delivers thefollowing Judgment:
t.On 9 January 2003 the United Mexican States (hereinafter referred to as
"Mexico") filedin the Registry of the Court an Application instituting proceed-
ings against the United States of America (hereinafter referred to as the

"United States") Tor"violations of the Vienna Convention on Consular Rela-
tions" of 24 April 1963{hereinafter referred to as the "Vienna Convention")
allegedlycommitted by the United Slates.
In its Application, Mexicobased the jurisdiction of the Court OnArticle 36,
paragraph 1,of the Statute of the Court and on Article 1 of the Optional Pro-
tocol concerning the Compulsory Settlement of Disputes, which accompanies
the Vienna Convention (hereinafter referred to as the "Optional Protocol").

2. Pursuant to Article 40, paragraph 2, of the Statute, the Application was
forthwith communicated to the Government of the United States; and, in
accordance with paragraph 3 of that Article, allStates entitled to appear before
the Court were notifiedof the Application.
3. On 9 January 2003,the day onwhich the Application was filed,the Mexi-
can Government also fled in the Registry of the Court a request for ihe indica-
tion of provisional measures basedon Article41 ofthe Statute and Articles 73,

74 and 75 of the Rules of Court.
By an Order of 5 February 2003, the Court indicated the following provi-
sional measures :
"(a) The United States of America shall,take all mcasures necessary to
ensurc that Mr. CCsarRoberto Ficrro Reyna, Mr. Roberto Moreno
Ramos and Mr. Osvaldo Torres Aguilera arc not executed pending
fin-a1judgment in these proceedings;
(b) The Government of the United States of America shall inform the
Court of all measures taken in implcm~ntationof this Order."

It further decided that, "untilhe Court has rendered its finaljudgment, it shall
remain seisedofthe matters" which formed the subject of that Order.
In a letter of 2 November 2003, the Agcnt of the United Statcs advised the
Court that the United States had "informed the relevant state authorities of
Mexico's application"; that, sincc the Order of 5 February 2003, the United
Slatcs had "obtained from them information about the status or the fifty-four
cases, including the three cases identified in paragraph 59 (I)(a) of that
Order"; and that the United States could "confirm that none of the named
individuals [had]been executed".

4. In accordance with Article43of the Rules ofCourt, the Registrar sentthe
notification referred to in Article 63, paragraph1, of the Statute to all States
parties to the Vienna Convention or to that Convention and the Optional Pro-
tocol.
5. By an Order of 5 February 2003,the Court, taking account of thc vicwsof
thc Parties,fixed 6 June 2903 and 6 October 2003, respectively, as the time-
limits for the filingof a Memorial by Mexico and of a Counfer-Memorial by
the United States. ainsicompode,

as to withdraw its request for relief in the cases of two Mexican nationals men-
tioned in the Memorial, Mr. Enrique Zambrano Garibi and Mr. Pcdro Hernin-

victing, and sentencing the 52 Mexican nationals on death row

right to diplomatic proteclion of its nationals, by failing to inform,
without delay, the 52 Mexican nationals after their arrest of their
right to consular nolification and access under Article 36 (1) (h)
of the Vienna Convention on Consular Relations, and by depriving

Mexico of iu right to provide consular protection and the 52

ingful and effective reviewand reconsideration of convictions and

applying the 'procedural dcfault' doctrine and other municipal law
doctrines that fail to attach legal significanceto an Article 36 (1) vio-
lation on its own tcrrns;

On behuIf of the Governnwntofthe United States,

"On thc basis of the facts and arguments made by the United Statetn
its Counter-Memorial and in these proceedings,the Government of the
United Statesof Amerlcarequeststhat the Court, taking info account that
the United States hasconformed its conducllothis Court's Judgrncntin

President or the Court in that case, lo all detained fore~gnnationals,

15.The present proceedings have been brought by Mexico against the
United States on the basis of the Vienna Convention, and of theOptional

Protocol providing for thcjurisdiction ofthc Court over "disputes arising
out of the interpretation or application"of the Convention. Mexico and
the United States are, and were at all relevant times, parlies to the Vienna
Convention and to the Optional Protocol. Mexico claims that the United
States has committed breaches of the Vienna Convention in relation lo
the treatment of a number of Mexican nationals who have been tried,
convicted and sentenced to death in criminal proceedings in the United
States. The original claim related to 54 such persons, but as a resultof
subscqucnt adjustments to its claimmade by Mexico (see paragraph 7

above), only 52 individual cascsare involved, These criminal proceedings
have been taking place in nine different Statcs of the United States,
namely California (28 cases), Texas (15 cases), Illinois (three cases),
Arizona (one case), Arkansas (one case), Nevada (one case), Ohio
(one case), Oklahoma (one case) and Oregon (one case), between 1979
and the present.

17. The provisions of the Vienna Convention of which Mexicoallegcs
violations are contained InArticle 36. Paragraphs 1and 2 of this Article
arc set out respectively in paragraphs 50 and 108 below. Article 36

relates, according to its title, to "Communication and contact with
nationals of the sending State". Paragraph I (b) of that Article provides
that if a nationalof that Stale "is arrested or committed to prison or to
custody pending trial or is detained in any other manner", and he so
requests, the localconsular post of the sending State is to be notified. The
Articlegoeson to providethat the "competent authorities of the receiving
State" shall "inform the person concerned without delayof his rights" in
this respect. Mexico claimsthat in the present case these provisions were
not complied with by the United Statcs authorities in respcct of the 52
Mexican nationals the subject of its claims. As a result, the United States
has according lo Mcxicocommitted breaches of paragraph I (h) ;more-
over, Mexico claims,for reasons to beexplained below(seeparagraphs 98

et seq.j, that the United States is also in breach of paragraph 1 (a) and
(c) and of paragraph 2 of Article 36, in view of the relationship of
these provisions with paragraph 1 (b).

18. As regards the terminology cmployed to designate thc obligations
incumbent upon the receiving State under Article 36, paragraph 1 (b),
the Court notes that thc Parlies have: used the terms "inform" and
"notify" in differing senses. For the sake of clarity, the Court, when
speaking in its own name in the present Judgment, will use the word
"inform" when referring to an individual being made aware of his rights
under that subparagraph and the word "notify" when referring to the
giving of notice to the consular post.
19. The underlying factsallegedby Mexicomay be briefy described as
foilows :some are conceded by the United States, and some disputed.

Mexico states that all the individuals the subjectof its claims were Mexi-
can nationals at the time of their arrest. It further contends that the
United Statesauthorities that arrested and interrogated these individuals
had sufficient information at their disposal to be aware of the foreign
nationality of those individuals. According to Mexico'saccount, in 50 of
the specified cases,Mexican nationals were never informed by the com-
petent United States authorities of their rights under Article 36, para-
graph 1 (b), of the Vienna Convention and, in the two remaining cases,
such information was not provided "without delay", as required by that
provision. Mexico has indicated that in 29 or the 52 cases its consular
authorities learned of the detention of the Mexican nationals only after
death sentences had been handed down. In the 23 remaining cases,
Mexico contends that it Iearned of the cases through means other than

notification to the consular post by the competent United States authori-
tics under Article 36, paragraph 1 (bj. It explains that in five cases this 53. Osvaldo Netzahualcbyotl Torres Aguilera

Iwas too late to affect the trials, that in 15 cases the defendants had
already made incriminating statements, and that it became aware of the
other three cases only after considerable delay.

20. OF the 52 cases referredto in Mexico'sfinal submissions,49 are
currently at different stagesof the proceedings before UnitedStatesjudi-
cial authorities at state or federal level, and in three cases, thosof
Mr. Fierro (caseNo. 31), Mr. Moreno (caseNo. 39)and Mr. Torres(case
No. 531 judicial remedies withinthe United States have already been
exhausted. The Court has been informed of the variety of types of pro-
ceedingsand forms of relief available in the criminal justice systems of

the United States, which can differ from state to state. In very general
terms, and according to the description offered by both Parties in their
pleadings, itappears that the52casesmay be classifiedinto three catego-
ries: 24 cases which are currently in direct appeal; 25 cases in which
means of direct appeal have been exhausted, but post-conviction relief
(habeas corpus), either at slate or at federal level,is still available; and
three cases in which nojudicial remedies remain.The Court also notes
that, in at least 33 cases, the alleged breach of the Vienna Convention
was raised by the defendant either during pre-trial, at tronlappeal or
in haheas corpus proceedings, and that some of these claims weredis-
missedon proceduralor substantivegrounds and othersare still pending.
To date, in none of the 52 cases havethe defendants had recourseto the
clemency process.

2 1. On 9 January 2003,the day on which Mexicofiledits Application
and a requesl for the indicatioof provisional measures, all52 individ-
uals the subject of the claims wereon death row. However,two days later
the Governor of the State of Illinois, exercisinghis power of clemcncy
review, commuted the sentences of a11convicted individuals awaiting
execution in that State, including those of three individuals named in
Mexico's Application(Mr. Caballero (case No. 45), Mr. Flores (case
No. 46) and Mr. Solache (case No. 47)). By a letter dated 20 January
2003, Mexicoinformed the Court that, further to that decision, it with-
drew its requestfor the indicationof provisional measureson behalf of
these three individuals,but that itspplication remained unchanged.In
the Order of 5 February 2003, mentioned in paragraph 3 above, on the
request by Mexicofor the indication ofprovisional measures,the Court
considered that it was apparent from the information before ilthat the
three Mexicannationals named in the Application who had exhausted all
judicial remediesin the United States (see paragraph 20 above)wereat

risk of execution in the followingmonths, or even weeks.Consequently,
it ordered by way oC provisional measurethat the United States take all
measures necessary to ensurethat these individuals wouldnotbe executed AVENAFT AUTRES (ARR~T) 27

22. As noted above, the present disputhas been brought bel'orcthe
Court by Mexico on thebasisof'theVienna Convention and the Optional
Protocol tothat Convention. Articl1of the Optional Protocol provides:

"Disputes arising outf the interpretation or application of the
[Vienna] Convention shall lie within the compulsory jurisdiction of
the International Court of Justice and may accordinglbcbrought
before theCourl by a written application made by any party to the
dispute being a Party to the present Protocol."

23. The United Statcshas presented a number of objections to the
jurisdiction of the Court, as well asa number of objections to thc
admissibility of the claims advancbyMexico. It is however thcontcn-
lion of Mexico that all the objections raised by the United Statare
inadmissible as having bccn raised after the expiratofthe time-timit
laid down by the Rules of Court. Mexico draws attention to the text of
Article 79,paragraph 1,of the Rules of Courl as amended in 2000,which
provides that

"Any objectionby the respondent to the jurisdiction of the Court
or to the admissibility of the application, or other objection the deci-
sion upon which is requested before any furlhcr proceedings on the
merits, shall be made in writing as sooas possible, and not later
than threc months after the delivery of the Memorial."
Thc previous text of this paragraph rcquired objections to be made
"within the time-limitxedfor deliveryof the Counter-Memorial". In thc
prcscnl case the Memorial of Mexico was filed on 23 June 2003; the

objections of the Unitcd States to jurisdiction and admissibility were
presented in its Counter-Memorial, filed on 3 November 2003, more
than four months later.
24. The United States has observed that, during the proceedings on
the request made by McxicoForthe indicationofprovisional measures in
this case, it specifically reservedits right to makejurisdictional arguments
at the appropriate stage, and that subsequently the Parties agreed that
there shouldbe a single round of pleadings. The Court would however
emphasize that parties to casesbefore il cannot, by purporting to "reserve
their rights" to take someprocedural action, exempt themselvesfrom the
applicationto such action of the provisioof the Statute and Rules ofpas exkutks tant que I'arretdefiniliren la prkscnle instance n'aurait pas

24. Les Etats-Unis ont quant a eux rappele que, lors de la phase dc

Mexique, ils s'ktaient expresskmentresew6 le droit de contester la com-
pilence de la Cour au stade opportun de laprocedure, et que les Parties
Ctaient ensuite convenucs qu'il neserait procedk qu'ii un seul tour de
pieces&rites. La Cour soulignera ccpcndant que les parties aux affaires
dont elleest srtisi~ne sausaient, sous prktexte{{rkserveleur droith)de
prendre telle ou telle decision de prockdure, soustraire ces dkcisioksCourt (cf. Application of the Convenlion on he Prevention and Punish-
ment r$ the Crime ofGenocide (Bosaio and Fierzegovinav. Yugosluviu),
Order of13 Seplember1993, I.C.J. Reports 1993, p. 338,para. 28).

Thc Court notes, however, that Articlc 79of the Rules applies only to
preliminary objections,as isindicated by the title of the subsection of the
Rules which it constitutes. As the Court observed in the Lockcrbie cases,
"if it is to be covered by Article 79, an objection mu. ..possess a 'pre-
liminary' characlcr", and "Paragraph 1 of Articlc 79 of the Rules of
Court characterizes as 'preliminary' an objection 'the decision upon

which is requested beforeany further proceedings"' (Quwlions c$ Infer-
pretalion andApplicalion of the 1'971 Montreal Conv~nliun urising ji-om
the Acrid Incident at LockerBic (Libyan Aroh Jarnahiriya v. United
Kingdom) (Libyan Arab Jamahiriya v. Uniled Stufes of America), Pre-
liminaryObjeclions,I.C.J.Repurls 1998,p. 26, para. 47; p. 131,para46) ;
and the effectof thetimely presentation of such an objection is that the
proceedings on the merits are suspended (paragraph 5or Article 79).An
objection that is not presented as a preliminary objection in accordance
with paragraph 1 of Article 79 does not thereby become inadmissible.
There are of course circumstances in which the party failing to put for-
ward an objection to jurisdiction might be held to have acquiesced in

jurisdiction (Appeui Relaling to the Jurisdictionuf the ICAO Council,
Judgment, I.C. J. Reporls 1972, p. 52, para. 13). However, apart from
such circumstances, a party failing to avail itself of the Article 79
procedure may forfeit the right to bring about a suspension of the pro-
ceedings on the merits, but can still argue the objection along with the
mcrits. That isindeed what the Unitcd Stateshas done in thiscase;and,
for reasons tobe indicated below, many of its objections are of such a
nature that they wouldin any event probably have had to be heard along
with the merits. Thc Court concludes that it shodd not exclude from
consideration the objections of the United States to jurisdiction and
admissibility by reason of the fact that they were not presented within
three months from the date of fiEingof the Memorial.

25. The United Stateshas submitted four objections to thejurisdiction

of the Court, and five to the admissibility of the claims of Mexico. As
noted above, these have not been submitted as preliminary objections
under Article 74of the Rules of Court; and they are not ofsuch a nature
that the Court would be required to examine and dispose of all of them in
limine, before dealing with any aspect of the mcrits of the case. Some arc
expressed tobe only addressed to certain claims; some are addressed to
questions of the remedies to be indicated if the Courtfind that breaches
of the Vienna Convention have beencommitted; and some are of such a
nature that they would have to be dealt with along with the merits. The
Court will however now examineeach of them in turn. I'applicationdes dispositionsdu Statut et du Rkglementde la Cour (voir

Cour; et leur nature n'exigepas quela Cour lesexamine toutes et statue;i

Certaines exceptions sont censies ne viser qu'une partie des demandes;
d'autres portent sur des questions likes anx remkdes que la Cour devra

indiquer si elleconstate que la convention de Vienna ete violke;d'autres
encore, par leur nature,demandent ii Etre traitles au stade du fond. La
Cour les examinera cependant dis maintenant une par une. 26. The United States contends that the Court lacks jurisdiction to
decide many of Mexico's claims, inasmuch as Mexico's submissions in
the Memorial asked theCourt to decide questions which do not arise out
of the interpretation or application of the Vienna Convention, and which
thc Uniled Slates has never agreed to submit to the Court.

27. By its first jurisdictional objection, the United States suggested
that the Memorial is fundamentally addressed to the treatment of Mexi-
can nationals in the federal and state criminal justice systems of the
United States, and the operation of the United States criminal justicesys-
tem as a whole. It suggested that Mexico's invitation to the Court lo
make what the United States regards as "hr-reaching aiid unsustainable
findingsconcerning the United States criminaljustice systems" would be
an abuse of thc Court's jurisdiction. At the hearings, the United States
contended that Mexico is asking the Court to interpret and apply the
treaty as if it were intended principally to govcrn the operation of a
State's criminal justicc system as it affects foreign nationals.

28. The Court would recallthat itsjurisdiction in the present case has

been invoked under the Vienna Convention and Optional Protocol to
determine the nature and extent or the obligations undertaken by the
United Statcs towards Mexicoby becoming party to that Convention. If
and so Taras the Court may find that the obligations accepted by the
parties to the Vicnna Convention included commitments as to the con-
duct of their municipat courtsin relation to the nationals of other parties,
then in order to ascertain whether there have been breaches of the Con-
vention, Ihc Court must be able to examine the actions of those courts in
the lightof international law. The Court is unable to uphold the conten-
tion of the United States that, as a matter of jurisdiction, it is debarred
from enquiring into the conduct of criminal proceedings in United States
courts. How far it may do so in the present case isamaller for the merits.
The first objection ofthe United Statcstojurisdiction cannot therefore be
upheld.

29. The second jurisdictional objection presented by the United States
was addressed to the first of the submissions presented by Mexico in its
Memorial (see paragraph 13above). The United States pointed out that
Article 36of the Vienna Convention "creates no obligations constraining
the rights of the United States to arrest a foreign national"; and that EXC~P~ION USINCQMP~~TENCE SOU[-EV~ES PAR I.ES ~TATS-UNIS

26. LesEtats-Unis affirment que la Cour n'a pas compitence pour sta-
tuer sur bon nornbre des demand~sdu Mexique du Caitque celui-ci,dans
les conclusions formulkes dans son memoire, a prie la Cour de se pro-
noncer sur des questions qui ne relkvent pas de l'interprktation ou de
l'application de la convention de Vienne et que les Etats-Unis n'ont
jamais accept&de soumettre a la Cour.

27. Par leur prerniire exception d'incompktence, les Etats-Unis
donnenl iientendre que lememoireconcerne essentiellementle traitement
des ressortissantsmexicainsdans Icssyslimcs dcjustice penale ambicaine,

Mcxiquc inviterail la Cour a formuler ce qu'ilsconsidkent comme udes
conclusions indkfendablcs et lourdes de consiquences sur les systemesde
justicepenale des Etats-Unis})ct a abuser de la compctcncc de la Cour.

Lors de la prockdure orale, les Etats-Unis ont soutenu que le Mexique
demandait i la Cour d'interprkter et d'appliques la convention comme si
die-ci visait principalemcnt i~rCgirle fonctionnement du systime dejus-
ticepinale d'un Etat quand celui-cis'applique ;ides Ctrangers.
28. La Cour rappelle que sa competence en l'espkcea CtCinvoquke au

savoir jusqu'ou elle peut proceder a cet exarncn cn l'espkceressorlit au

ne saurait donc Etreaccueillie.

29. La deuxiPme exception d'incompktence des Etats-Unis visail la
prernikc dcs conclusions presentees par le Mexique dans son memoire
(voir paragraphe 13ci-dessus).LesElats-Unis faisaient valoir en I'occur-

rence que l'articl35 de la convention de Vienne crnYinstitu[,ait.aucunc
obligation ltmitant lcdroitdesEtats-Unis d'arreter un ressortissant ktran-sirniiarlythe "detaining, trying, convicting and scnlencing" of Mexican
nationals could not constitute breaches of Article 36, which merelylays
down obligations of notification, The United States deduced from this
that the matters raised inMcxico'sfirst submission are outside the juris-
diction of the Court under the Vienna Convention and the Optional Pro-
tocol, and it maintains this objection in response to the revised submis-
sion, presented by Mexico at the hearings, whereby it asks the Court to
adjudgeand declare:

"That the United States of America, in arresting, detaining, try-
ing, convicting, and sentencing the 52 Mexican nationals on death
row described in Mexico'sMemorial, violated its international legal
obligations to Mexico, in its own right and in the exerciseof its right
to diplomatic protection of its nationals,by failingto inform, with-

out dclay, the 52Mexican nationals after their arrest of their right lo
consular notification and access under Article 36 (I) (b) of the
ViennaConvention on Consular Relations, and by depriving Mexico
of its right to provide consular protection and ~hc52 nationals'
right to receive such protection as Mexico would provide under
Article 36 (1) (u) and (c) of the Convention."

30. This issueisa question of interpretation of the obligationsimposed
by the Vienna Convention. It is true lhat the only obligation of the
receivingState toward a foreign national that is specificallyenunciatedby
Article 36, paragraph 1(b), of heVienna Convention is to inform such
foreign national of his rights, when he is "arrcsted or committed to
prison or to custody pending trial or is detained in any other manner";
the text does not restrain the receiving Slate from "arresting, detaining,
trying, convicting, and sentencing" the foreign national, or limit its
power to do so. I-lowever,as regards the detention, trial, conviction and
sentence of its nationals, Mexico argues that depriving a foreign national

facingcriminal proceedings ofconsular notification and assistancerenders
those proceedings fundamentally unfair.Mexico explains in this respect
that :

"Consular notification constitutes a basic cornponcnt of due pro-
cess byensuring both the procedural equality of a foreign national
in the criminal process and the enforcement of other fundamental
due process guarantees to which that national is entitled", AVENA ET AUTRES (ARKE'I') 31

S'agissantde la dktention, dujugernent, de la dklaration de culpabilitket
de la condamnation de ses ressortissants, le Mexique soutient cependant
que le fait de priver un Ctranger,lorsqu'une prockdure penale estengagk
son encontre, de la notification et de l'assistanceconsulaires rend cette
prokdure fondamentalement inkquitable. Le Mexique explique i cet

ceedings against fbreign nalionals." In Mexico's contention, "consular
notification has been widely recognized as a fundamental due process
right, and indeed, a hutwanright". On this basis itargues that the rights
of the detained Mexicannationals have been violated by the authorities
of thc Unitcd Slales, and that those nationals have been "subjectedto
criminal proceedingswithout the fairnessand dignity to whicheach per-

son iscntillcd". Conscquenlty,in the contention of Mexico, "the integrity
of these proceedingshas been hopelessly undermined, their outcomes
rendered irrevocably unjust".For Mexico to contend, on this basis,that
not mcrcly the faiiurc to noliry, but the arrest, detention, trial and con-
viction ofitsnationals were unlawfulis to argue in favour of a particular
it~terpretationof the ViennaConvention. Such an interpretation may or
may not be confirmed on the merits,but is not excluded from the juris-
diction conferred on the Court by the Optional Protocol lo thc Vicnna
Convention. The second objection of the United Slales Lo jurisdiction
cannot therefore be upheld.

71. The third objection by the United Statcs lo the jurisdiction ofthe

Court refersto the first of the submissionsin the MexicanMemorialcon-
cerning remedies.By that submission,whichwas confirmedin substance
in the final submissions. Mexico claimed that

"Mexicois cntitled to restiluiiin integrum,and the United States
lhercfore isunder an obligation lo restore the sralus quo ante, that
is, rc-establishthc situation that existedat thetime of the detention
and prior to the interrogation of, proceedings against, and convic-
tions and sentences of, Mexico's nationals in violationof the United

States'international legal obligations . . ."
On that basis, Mexicowent on in its first submissionto invite the Court
to declarethatIheUnitcd States was bound to vacatethe convictionsand
sentences of the Mexicannationals concerned, to excludefrom any sub-
sequent proceedingsany statementsand confessionsobtained rrom them,
to prevent the application of any procedural penalty for failureto raise a
timely defenceon the basis ofthe Convention, and to prevent the appli-

cation of any municipal law rule preventing courts in the United States
from providing a rcmedy for the violation of Article 36 rights.

32. The United States objects that so to require specificacts by the
United States in its municipal criminal justice systems would intrude
deeply into the independence of its courts; and that for the Court to AVENA ET AUTRES (ARR~~T) 32

En se fondant sur cet argument, le Mexiquea poursuivi, dans sa premiire
conclusion, en priant la Cour de dire quc Ics Elats-Unis kaient tenus
d'annuler les verdicts de culpabilitk sendus et les peines prononckesi

des Etats-Unis de la possibilitk de porter remede i une violation dcs

32. Les Etats-Unis retorquent qu'exigerde teur part des mcsures pri-

unc atteinte gravei l'indkpendance de lcursjuridictions; et qu'endecla-

24declare that the United States is undera specificobligation to vacate con-
victions and sentences would be beyond its jurisdiction. The Court, the
United States claims, has no jurisdiction to review approprialeness of
sentences in criminal cases,and even lessto determine guiltor innocence,
matters which only a court of criminal appeal could go into.

33. For its part, Mexicopoints out that the United States accepts that
the Court has jurisdiction to interpret the Vienna Convention and to
determine the appropriate form of reparation under international law. In
Mexico'sview,these two considerations are sufficient to deltat the third

objection to jurisdiction of the United Statcs.
34. For the same reason as in respect of the second jurisdiclional
objection, the Court is unable to uphold the contention of the United
States that, even if thc Court were to find that breaches of the Vienna
Convention have been committed by the United States of the kind
alleged by Mexico, itwould still be without jurisdiction to orderresridutitl
in integrum as requested by Mexico. The Court would recall in this
regard, as it did in theLuGrundcase, that, wherejurisdiction cxists over
a dispute on a particular matter, no separate basis for jurisdiction is
required by the Court in order to consider the remedies a party has
requested for the breach of thc obligation (I.C.J. Reports 2001, p. 485,
para. 48).Whether or how far the Court may order the remedy requested
by Mexico are matters to be determincd as part of the merits of the dis-
pute. The third objection of the United States to jurisdiction cannot

therefore be upheld.

35. Thc Fourthand last jurisdictional objection of the United States is
that "the Court lacks jurisdiction to determine whether or not consular
notification is a 'human right', or to declare fundamental requirements of
substantive or procedural due process". Asnoted abovc, itis on the basis
of Mexico's contention that the right to consular notification has been
widely recognized as a fundamental due process right, and indeed a
human right, that it argues that the rights of the detained Mexican
nationals have been violated by the authorities of the United States, and
that they have been "subjected to criminal proceedingswithout the fair-
ness and dignity to which each person is entitled". The Court observes
that Mexico has presented this argument as being a matter of inter-
pretation of Article 36, paragraph 1 (b), and therefore belonging to
the merits. The Court considers that this is indeed a question of inter-

pretation OFthe Vienna Convention, Torwhich it has jurisdiction ; the
fourth objection of the United States to jurisdiction cannot therefore be
upheld. AVENA ET AUTRES (AKKET) 33

rant que les Etats-Unis ant l'abligation particulikre en l'espke d'annuler

33. Le Mexique, pour sapart, expose que lesEtats-Unis reconnaissent
la compktence de la Cour pour interprkter la convention de Vienne et
pour dire quelle est lareparation requise en droit international. Selon 1e
Mexique, ces deux Climents suffisent pour rejeter latroisierne exception
d'incompetence desEtats-Unis.
34. Pour le motif dkji exposi lors de I'examende la deuxikmeexcep-

conskquent, ressortit au fond. La Cour considere qu'il s'agit 18effective-

Vienne, qu'ellea compktencepour traiter; dkslors la quatrikme exception
d'incompktencesoulevCepar les Etats-Unis ne saurait &re accueillie.

* * 36. In its Countcr-Memorial, the United States has advanced a number
of arguments presented as objections to the admissibility of Mexico's
claims. 1t argues that
"Before proceeding, the Court should weigh whether characteris-
tics of the case before it today, or special circumstances related to

particular claims, render either the entire case, or particular claims,
inappropriate for furtherconsideration and decision by the Court."

37. The first abjection under this head is that "Mexico's submissions
should be found inadmissible because they seekto have this CourtFunc-
tion as a court of criminal-appealv; there is, in the view of the United
States, "no other apt characterization of Mexico's two submissions in

respect of remedies". The Court notes that this contention is addressed
solelyto the question of remedies.The United States does not contend on
this ground that the Court should declinejurisdiction to enquire into thc
question of breaches of the VicnnaConvention at all, but simply that, if
such breaches are shown, the Court should do no more than decide that
thc United States must provide "sevicw and reconsideration" along the
linesindicated in the Judgment in.the LaGmndcase (I.C. J. Reports 2001,
pp. 513-514,para. 125).The Court notes that this is amatter of merits.
The first objectionof the United States to admissibility cannot therefore
be upheld.

38. The Court now turns to the objection of the Unitcd States
based on the rule of exhaustion of local remedies. The Uniled Slatcs
contends that the Court "should find inadmissible Mexico's claim lo
exercise its right of diplomatic protcction on behaIf of any Mexican
national who has failed to meet the customary legal requirement of
exhaustion of municipal remedies". It asserts that in a number of the
cases the subject of Mexico's claims, the detained Mexican national,
even with the benefit of the provision of Mexican consular assistance,
failed to raise the alleged non-compliance with Article 35,paragraph 1,
of the Vienna Convention at the trial. Furthermore, it contends that
all of the claims relating tocascs referred to in the Mexican Memorial
are inadmissible bccause local remedies remain available in every case.
It has drawn attention to the fact that litigation is pending bcforc

courts in the United States in a largenumber of the cases the subject
of Mexico's claims and that, m those cases whcrc judicial remedies
have been exhausted, the defendants have not had recourse to the
clemency process available to them; from this it concludes that none 36. Dans leur conlre-memoire, les Etats-Unis ont prksente un certain
nombre d'arguments en tan1 qu'exceptionslila recevabiliti:des demandes

38. La Cour en vient maintenant a l'exception dcs Etats-Unis fondee
sur la rigle de I'Cpuisernenldes voies de recours inlernes. Les E'tats-Unis
soutiennent que la Cour ctdoitjuger irrecevablela prktention du Mexique

tissant rnexicainqui n'a pas Cpuiseles voiesde recours internes ainsi que

outre que les demandes relatives aux cas visCsdans le rnkmojre du Mc-
xiquesont toutes irrccevablesparce que, dans chaque affaire,des voiesde
recours internes restent disponibles. 11sattirenl I'attention sur le queiz

engag6 la proccdure de recours en grace qui leur est ouverte; d'ou ilsof the cases "is in an appropriate posture for rcviewby an international
tribunal".
39. Mexico respondsthat the rule of exhaustion of local remedies can-
not preclude the admissibilityof its claims. It first states that a majority
of the Mexican nationals referred to in paragraph 16above have sought
judicial remediesin the United States based on the Vienna Convention
and that their claims havebeen barred, notably on the basis of thepro-
ceduraldefault doctrine. In this regard, itquotesthe Court's statementin
the LaCrandcase that

"the United States may not. . rely before this Court on this fact in
order to preclude the admissibilityof Germany's [claim] . .., as it
was the United States itselfwhich had failed to carry out its obliga-
tion underthe Convention to inform the LrtGrand brothers" (I. C.J.
Reports 2201, p. 488, pard. 60).

Further, in respcct of the other Mexican nationals, Mexico asserts that

"the courts of the United States have never granted a judicial
remedy to any foreign national for a violation of Article 36. The
United States courts hold either that Article 36 does not create an

individual right,or that a foreign national who has been denied his
Article 36 rights but given hisconstitutional and statutory rights,
cannot establish prejudiceand therefore cannot get relief."

It concludes that the available judicial remedies are thus ineffective.As
for clemency procedures, Mexicocontends that they cannot count for
purposes of the rule of exhaustion of local remedies,becausethey are not
a judicial remedy.

40. In its final submissions Mexicoasks the Court to adjudge and
declare that the United States,in failingto comply with Article 36, para-
graph 1, of thc Vienna Convention, has "violaled its international lcgal
obligations to Mexico,in its own Tight and in the exerciseof its right of
diplomatic protection ofits nationals".

The Court would first observethat the individual rights of Mexican
nationals under paragrapIh(b) of Article 36or the ViennaConvention
are rights which are to be asserted, at any rate in the first place, within
the domestic legal systemof the United States. Only whenthat processis
completed and local remediesare exhausted would Mexico be entitledto
espouse the individual claimsof its nationals through the procedure of
diplomatic protection.

In thepresent case Mexico doesnot, howcver,claimto bcacting solely

on that basis. It also asserts its own claims, basingthem on the injury
which it contends that ir has its+$ suffered, directly and ~hro~igh irsconcluent qu'aucune des affaires crnese trouv[ej en l'etat voulu pour Etre
rkexaminee par une juridiction internationale )>.
39. Le Mexique retorque que la reglc de I'Cpuisementdes voies de re-
cours internes ne saurait faire obstacle;ila recevabilite de ses demandes.
I1indique, en premier lieu, que la majoriti: des ressortissants mexicains
visksau paragraphe 16ci-dessus ont form6 des recours judiciaires fondts
sur la convcnlion de Vienne aux Etats-Unis et ont kkt dCboutks,notam-
ment en raison de la doctrine de la carence prockduralc. A cet egard,
il invoque le prononck de la Cour en l'affaire LnGrand, selon lequel

(les Etats-Unis ne [pouvaient] seprkvaloir ...devant la Cour dc cette
circonstance pour fairc obstacle h la recevabilitk [de la demande
allemande] ...d2s lors qu'ils avaient eux-mhes failli a l'exkcution
de leur obligation, en vertu de la convention, d'informer les frires
LaGrand~ (C.1.J. Recueil2001, p. 488, par. 60).

En outre, s'agissant des autres ressortissants mexicains, le Mexique in-
dique ce qui suit:
ales juridictions des Etats-Unis n'ont jarnais fait droit au moindrc

recours judiciaire intenti. par un ressortissant Clranger pour une vio-
lation de l'article36.Cesjuridictions dkclarent soit que I'article3ne
crke pas dc droit individuel, soit qu'un ressortissant Ctranger qui a
Cti:privkdes droits qu'il tenait de I'article36,mais qua en revanche
btnCfici6de ceuxprtvus par la Constitution et leslois americaincs, ne
peut Ctablir l'existenced'un prijudice et donc obtenir ri.paralian.)>
Le Mexique conclut que les recours judiciaires disponibles sont dis lors

incfficaces. Quant itla prockdure de recours en grice, ellc ne saurait,
selon le Mexique, entrer en ligne de compte aux finsde la rigle de I'epui-
sement des voies de recours internes, puisqu'il ne s'agit pas d'un recours
judiciaire.
40. Le Mexique, dans ses conclusioils finales, grie la Cour de dire et
jugr que les Etats-Unis, en ne se conformant pas au paragraghe 1 de
l'article 36 de la convention de Yienne, ant crviolCleurs obligations juri-
diques internationales envers le Mexique agissant en son nom propre et
dans I'exercicedu droit qu'acet Etat d'assurer la protection diplomatique
de ses ressortissants>).
La Cour fera d'abord observer que les droits individuels que les res-
sortissants mexicains tirent de 1'alinCabJ du paragraphe 1 de I'article 36
de la convenlion de Vienne sont des droits don1 la rkalisation doit, en
tout cas en premier lieu, etre recherchk ddan le cadre du systkmejuri-
dique intemc des Etats-Unis. Ce n'est qu'une fois ce processus mentB
son terme et les voies de recours internes Cpuisies que le Mexique pour-

rait faire siennes des demandes individuelles de ses ressortissanls par le
mkanisme de la protection diplomatique.
En I'espkcele Mcxique ne prktend cepcndant pas agir seulementpar ce
mkcanismc. I1prksente en outre des demandes qui lui sont propres en se
fondant sur Itprkjudice qu'il declare avoirsubihi-meme, directemenl etnulionul.~,as a result of the violation by the United States of the obliga-
tions incumbent upon il under Article 36, paragraph 1 (a), (B) and (uj.

The Court would recallthat, in the LaCrurzdcase, it recognizedthat

"Articlc 36, paragraph 1 [of the Vienna Convention], creaks indi-
vidual rights [forthe national concerned], which . . may be invoked
in this Court by the national State or the detained person" (I.C.J.
Reports2001, p. 494, para. 77).
It would further observe that violations of ~hc rights of the individual

under Article 36 may entail a violation of the rights of the sending State,
and that violations of the rights of the latter may cntail a violatioof'the
rights ofthe individual. In these specialcircumslances of interdependence
of the rights of the State:and of individuai rights, Mexico may, in sub-
mitling a claim in its own name, requcst the Court to rule on the viola-
tion of rights which it claims to have suffered both directly and through
the violation of individual rights conferred on Mcxican nationals undcr
Article 36,paragraph 1(b). Thc duty to exhausl local remedies does not
apply to such a request. Further, for reasons just explained, the Court
does not find it necessaryto deal with Mexico's claims of violationunder
a distinc~ heading af diplomatic protection. Withoul needing to pro-
nounce at this juncture on the issues raised by the procedural default
rule, as explained by Mexico in paragraph 39 above, the Court accord-
inglyfinds that the second objection by lhc United States lo adnlissibility
cannot be upheld.

41. The Court now turns to the question of lhc alleged dual national-
ity of certain of the Mexican nationals the subjcct of Mexico's claims.
This question is raised by the United States by way of an objection lo the
admissibility of those claims: the United States contends that in its
Memorial Mexico had failed 10establish that it may cxercisediplomatic
protection based on breaches of Mexico's rightsundcr the Vienna Con-
vention with respect to those of its nationals who are also nationals of the
United States. The United States regards it as an acccpted principle that,
when a person arrested or detained in the receivingState is a national of
that State,then even if he is alsoa national of another State party to the
Vienna Convention, Article 36 has no application, and the authorities
or the receiving Slate are not required to procced as laid down in that
Article; and Mexico has indicated that, Torthe purposes of the present
case it docs not contest that dual nationals have no right to be advised

of rheir rights undcr Article 36.

42. It has howeverto be recalledthat Mexico, in addition to seekingto
exercise diplomatic protection of its nationals, is making a claim in its AVENA ET AUTRES (ARK&T) 36

u Iruvers se.~rtr.ssortissadusfait de la violation par les Etats-Unjs des
obligations qui leur incornbenta son igard en vertu des alinkas a), h) et
cJ du paragraphe 1de I'articlc36.
La Cour rappellera que, dans l'affaire LuGrunrl,elle a reconnu que

ctleparagraphc 1 de l'article 36 crke [pour le ressorlissant concernk]
des droits individuels qui ... peuvent @treinvoquks devant la Cour
par I'Etat dont la personne dktenue a la nationalitk})(C.I.J. Recueil
2001, p. 494, par. 77).
Elle observ~raen outre queloute violation dcsdroits que l'individu tient
de l'article36 risque d'entrainer une violation des droits de 1'Etatd'envoi

et que toute violation des droits de cc dernier risque de conduiri une
violation des droitsde l'individu. Dans ces circonstances loutes particu-
liires d'interdkpendance des droits de 1'Etatetdcs droits individucls, le
Mexique peut, en sournettant une demande en son non7propre, inviter la
Cour istatuer sur la violation des droits dont il soutient avoir elk victime
Bla fois dircctement eti travcrs la violation des droits individuets confk-
rks rises ressortissants par I'alinea b) du paragraphe 1 de l'arlicl36.
L'obligation d'tpuiser les voies de recours interncs ne s'appliquepas a
une telle dernandc. Au demeurant, pour les motifs qui viennent d'Ctre
exposks, la Cour n'esdme pas necessaire de traiter des demandes mexi-
I cainesconcernant lesditesviolations sous \'angledistinct de la protection
diplomatiquc. Sans qu'ily aitlieu a ce stadc d'aborder lesquestions sou-
levies par la rigle de la carence proc6durale, tdles qu'exposkes par le
Mexique au paragraphe 39 ci-dessus, la Cour conclut que la deuxieme
exceptiondYirrecevabili~sCoulevkepar IcsEtats-Unis ne saurait donc Etre

accueillie.

41. La Caur en vient rnainlcnant a la question de la double nationalite
qu'auraient cerrains des ressortissants mexicains raisant l'objet des de-
mandes du Mexique. Les Etats-Unis soulkventcette question en opposant
une exception a la recevabilitkdesdites den~andes:ils soutiennent que le
Mexique n'avait pas Ctabliclansson memoircqu'ilpouvait, au titre de la
violation desdroits qu'il tire de la convention de Viennc, exercerla pro-
tcction diplomatique en faveur de ccux de ses ressortissants qui sont tga-
lemcnt ressortissants des Etats-Unis. Les Etats-Unis tiennent pour un
principe ginkralement admis que, lorsqu'une personnc arrCtk ou placCe
en dkl~ntion dans 1'Elatde risidencc est ressortissanlc de cet Etat, I'ar-
ticle 36n'estpas applicable, meme si cette personne est kgalemcntressor-
tissante d'un autre Etat partik la convention de Vicnne, et les autoritis
de 1'Etalde rksidencenc sont pas teiiucs de procider comme prCvudans
cct article; eIc Mexique a indiqui que, aux fins de la prksenle affajre,

il ne conteste pas que les ressortissants ayant la double nationalit6 ne
peuvent prktcndre a un droil d'ttre inforrnksen vertu de l'article 36.
42. 11hut toutefois rappeler que le Mexique, outre qu'il cherche i
exercerla protection diplomatique ;iI'Cgardde scs rcssortissants. prkscnteown right on the basis of the alleged breaches by the United States of
Article 36 of the Vienna Convention. Seen from this standpoint, the
qucstion of dual nationality is not one of admissibility, but of merits. A
claim maybe made by Mexicoof breach of Article 36of the Vienna Con-
vention in relation to any of its nationals, and the United States is therc-
upon free to show that, because the person concerned was also a United
Statesnational, Article 36 had no application to that person,so that no
breach of treaty obligations could have occurred. Furthermore, as regards
the claim to exercisediplomatic protection, the question whether Mexico
is entitled to protecta person having dual Mexican and United States

nationality is subordinatedto the question whcther,in relation to such a
person, the United States was under any obligation interns of Article 36
of the Vienna Convention. It is thus in the courseof its examination of
the merits that the Court will have lo consider whcther the individuals
concerned, or some of them, were dual nationals in law. Without preju-
dice to the outcome of such examination, the third objection of the
UnitedStates to admissibility cannot therefore be upheld.

43. The Court now turns to the fourth objection advanced by the
United Slates to the admissibility of Mexico'sclaims: the contention that

"The Court should not permit Mexico to pursue a claim against
theUnited States with respect to any individual case where Mexico
had actual knowledge of a breach of the Vienna Convention] but
failedto bring such breach to the attention of the United States or
did so only after considerable delay."

In the Counter-Memorial, the United States advances two considerations
in support of this contention: that if the cases had been mentioned
promptly, corrective action might have been possible; and that by
inaction Mexico created an impression that it considered that the
United States was meeting its obligations under the Convention, as
Mexico understood them. At the hearings, the United States suggested
that Mexico had in effectwaivedits right to claimin respect of the alleged
breaches of the Convention, and to seek reparation.

44. As the Court observed in the case of Certai Phosphate land.^in
Nauru(Nouru v. Austrulia), "delay on the part of aclaimant Statemay
render an application inadmissible", but "international law does not lay
down any specifictime-limitin that regard" (1.C.J. Reports1992,pp. 253-
254, para. 32). In that casethe Court recognized that delay might preju-

dice the respondent State "with regard to both theestablishment of the
facts and the determination of the content of the applicable Iaw" (ihid,
p. 255,para. 36),but it has not been suggestedthat there isany such risk
of prejudice in the present case. Sfar as inadmissibility mightbe based
on an impIied waiver of rights, the Court considers that only a much une demande en son nom propre a raison des violations a1lCgui.e~ de
I'article 36 de la convention de Vienne cornmises par Ics Etats-Unis. De
ce point de vue, la question de la double nationaliti: n'est pas une ques-
lion de recevabilitk,mais de fond.Le Mexiquepeut fair valoir une viola-
I lion de l'article 36 de la convention de Vienne a l'kgard de n'importe
lequel de ses ressortissants, aprk quoi il est loisible aux Etats-Unis de
dkmontrer que, I'inlbessk etant egalement ressortissant des Etats-Unis,
I'article6 ne s'appliquait pas son endroit, de sorte qu'aucune obliga-
tion conventionnelle ne pouvait &treviolCe. Qui plus est, pour cc qui
concernela prktention d'exercerla protection diplomatique,la question de
savoir si le Mcxique a le droit de protiger une personnc ayant la double
nationalit6 - mexicaine et amkricainc - est subordonnke a celle de
savoir si les Etats-Unis Ctaienttenus d'une obligation ri1'Cgard de cette

personne aux termes de I'article 36 de la convention de Vienne. C'est
donc lors de I'examende l'affaire au fond que la Cour devra apprecier si
lesintkresds, ou du moins certains d'entre eux,avaient en droit la double
nationalitk. Sans prejudice de I'issuedecet examen, la troisikme excep-
I tiond'irrecevabilitedes Etats-Unis ne saurait donc Ctreaccueillie.
*

43. La Cour passera maintenant BI'examende la quatrikrne exccption
d'irrecevabililt!opposke par les Etats-Unis aux demandes du Mexique, h
savoir que:
t{[l]aCour ne doitpas permettre au Mexique de faire valoir une prk-
lcntion a l'encontredes Etats-Unis pour les cas oh le Mexique avait
effectjvernent connaissancc d'une violation dc la [convention dc
Yienne] mais n'a pas porti: cettc violation ;i l'attention des Etats-
Unis ou I'a fait avec un retard considkrable~.

Dans le contre-mkmoire, les Etnts-Unis font valoir deux considCrationsa
l'appuide cet argument: la premiere estque, sices casnvaient Cti:signalks
promptement, il aurait kte possible d'agirpour corriger la situation; la
seconde est que le Mexique, par son inaction, aurait donne I'irnpression
qu'il considerait que Ics Etats-Unis rcrnplissaient les csbtigations leur
incombant en verlu de la convention, telles que le Mexique les interprk-
tait. Lorsdes audiences, les Etats-Unis ont avancCque le Mexique avait,
de fait, renonck a se prkvaloir de son droit ri contester les violations alle-
gueesde la convention et sidemander rkparation.
44. Comme la Cour I'afait observer dans I'affairede Certaines terres
ciphospkares d Nauru (Nauru e. Australie), si ctle retard d'un Etat
demandeur peut rendre une requkte irrccevable~>c,rledroit international
n'imposepas h cet kgard une limicede temps dkterminke >>(C.I.J. Recueil
1992, p. 253-254,par. 32). Dans cette affaire, la Cour a reconnu qu'un
i retard pouvait porter prkjudice a 1'Etat dkicndeur {ten ce qui concerne
lant l'etablissement des faits que la dktermination du contenu du droit

applicable>>(ibid.,p. 255,par. 36),mais un tel risque de prejudicen'a pas
Ctkevoque dans Pa prksente espece. Pour autant qu'une irrecevabilitk
puisse Stre fondCesur la renonciation tacite rdes droits, la Cour consi-more prolonged and consistent inaclion on the par1 of Mexico than any
that the United Slatcs has alleged might be interpreted as implying such
a waiver. Furthermore, Mexico indicated a number of ways in which it
brought to the altcntion of the United States the breaches which itper-
ceived of the Vienna Convenlion. The fourth objection of the United
States to admissibility cannot thereforebe upheld.

45. The Court has now to examine the objection of the United States
that the claim of Mcxico is inadmissible inthat Mexico should not bc
allowed to invoke against the United States standards that Mexico does
not follow in its own practice. The United States contends that, in
accordance wilh basic principles of administration of justice and the
equality of States, both litigants are to be hcld accountable to the same
rules of international law. The objection in this regarwas presented in
terms of the interpretation of Article 36 of the Vienna Convention, in the
sense that, according to the Unikcd States, a treaty may not be inter-
preted so as to impose a significantlygreater burden on any one party
than the other (DiversionoJ Water from lizeMeuse, Judgment, 1937,
P.C.I.J., Series AIB, No. 70, p. 20).

46. The Court would recall that thc United Statcs had already raiscd
an objection of a similar nature before it in the LaGrundcase; there, the
Court held that it need not decide "whether this argument of the United
States, if true, would resull in the inadmissibility of Germany's submis-
sions", sincethe United States had failed to prove that Germany's own
praciie did not conrorm to the standards it was demanding from the
United States (I. J. Reports 2001, p. 489, para. 63).

47. The Court would recall that is in any event essentialto have in
mind the nature of the Vienna Convention. It lays down certain stand-
ards to bc observed by all States parties, with a view lo the "unimpeded
conduct of consular relations", which,as the Court observed in 1979,is
important in present-day international law "in promoti~lgthe develop-
ment of lkicndlyrelations among nations, and ensuring protection and

assistance for aliens resident in the territories of other States" (Unired
Srutes Diplomutic und Consulur Slug in Tehran (Unilud Stures of
Amerku v. Iran}, Prtlvisional Measures, Order of 15 Dccember 1979,
I.C.J. Reports 1979, pp. 19-20,,para. 40). Even if it were shown, there-
fore, that Mexico'spractice as regards the application of Article36 was
not beyond reproach, this would not constitutc aground of objection to
the admissibility of Mexico's claim. The fifth objection of the United
States to admissibility cannot thereforebe upheld. dere que seulc une inaction bien plus longue et systkmatique quc celle
qu'ont alleguee les Etats-Unis en ce qui concerne le Mexique pourrait
6tre interprktke comme impliquan tune telle renonciation. D'ailleurs, le
Mexique a signale plusieurs voies qu'il avait utiliskes pour portcr ft
I'attention des Etats-Unis cequ'il tenstitpour des violations de la convcn-
tion de Vienne. La quatriime exception d'irrecevabilitksoulevee par les

Etats-Unis ne saurait donc ktre accueillie.

45.La Cour doit maintenant examiner l'exception des Etats-Unis
selon laquelle la demande mexicaine est irrecevable en ce sens qilc le
Mexique nedevrait pas etre autorid i invoquer conlre les Etats-Unis des
nomcs qu'il ne suitpas dans sa propre pratique. Selon 1esEtats-Unis, les
principes de la bonne administration dc la justice et l'egalite des Ems
exigent que les deux Parties soient tenues de respecter les mCrnesrkgles
de droit international. CC~ igard, l'exceptiona Ct6prtsentke commeayant

dcs Etats-Unis ne sausait donc ktre accueillic. 48. Having established that it has jurisdiction to entertain Mexico's
claimsand that they are admissible,the Court willnow turn to the merits
of those claims.

44. In its final submissions Mexico asks the Court to adjudge and
declare that,
"the United States of America, in arresting, detaining, trying, con-

victing, and sentencing the 52 Mexican nationals on death row
described in Mexico'sMemorial,violated itsinternational legalobli-
gations toMexico,in its own right and in the exerciseof its right to
diplomatic protection of its nationals, by failingto inform, without
delay, the 52 Mexican nationals after their arrest of their right to
consular notification and access under Article 36 (1) (h) of the
Vienna Convention on Consular Relations,andbydepriving Mexico
of its right to provide consular protection and the 52 nationals'
right to receive such protection as Mexico would provide under
Article36 (1) (a) and (c) of the Convention".

50. The Court has already in its Judgment in the LaGrund case
describedArticle 36, paragraph 1, as "an interrelated regime designed to
facilitatehe implementationof the system ofconsularprotection" (I.C.J.
Reporis 2001, p. 492, para. 74). It is thus convenient to set out the
entirety of that paragraph.

"With a viewtoward facilitating theexerciseof consular functions
relatingto nationals of the sending State:

(a) consular officersshall be free to communicatewith nationals of
the sendingState and to have accessto them. Nationals of the
sendingState shall have the same freedom withrespectto com-
munication with and accessto consular officersof the sending
State;
(h) if he so requests, the competent authorities of the receiving
State shall, withoutdelay, inform the consular post of the send-
ing Stateif,within its consular district, a nationoi that State:
is arrested or committed to prison or tocustody pendingtrial
or is detained in any other manner. Any communication
addressed to the consular post by the person arrested,inprison,

50. Dans son arrCtrendu en I'affaireLaGrand,la Cour a dkji prksente
le paragraphe I de I'article 36 comme definissant ciun regime dont les
divers ClCmentssont intcrdipendants et qui est conqu pour faciliter la
mise en Eeuvredu systltnc dc protection consulairen (C.I.J.Recueil2001,

gralitk.

tissants de 1'Etatd'envoi soit facilite:

without delay.Thc said authorities shall inform the person con-
cerned without delay of his rights under this subparagraph;

(c) consular officersshall have thc right to visit a national of the
sending State who is in prison, custody or detention, to con-
verse and correspond with himand to arrange for his legalrep-
resentation. They shall also have the right to visit any national
of the sending State who is in prison, custody or detention in
their district inrsuance of ajudgment. Nevertheless,consular

officcrsshall refrain from taking action on behallofa national
who it;in prison, custody or detention ir he expressly opposes
such action."

51.The United States as the receiving State does not deny its duty
to perform thesc obligations. However, it claims that the obligations
apply only to individuals shown to be of Mexican nationality alotie, and
not to those of dual MexicanlUnilcd States nationality. The United
States further contends irzteralia that it has not committed any brcach
of Article 36, paragraph 1 (b), upon the proper interpretation of

"without delay" as used in that subparagraph.

52. Thus two major issues under Article 36,paragraph 1 (b), that are
in dispute between the Parties are, first,e question of the riationality of
the individuals concerned;and second, the question of the meaning to be
givcn to the expression "without delay". Thc Court will examine each ui'
these in turn.

53. The Parties have advanced thcir contentions as to nationalily in
three different legalcontexts. The United Stateshas begun by making an
objection to admissibility, which the Court has already dealt wilh (see:
paragraphs 41 and 42 above). The United States has further contended
that a substantial number of the 52 persons listed in paragraph 16
above were United States nationals and that it thus had no obligation

to these individuals undcr Article 36, paragraph 1 (h). The Court will
address this aspect of the matter in the followingparagraphs. Finally, the
Parties disagree as to whether the requirement under Article 36, para-
graph 1 (h), for the information to be given "without delay" becomes
operalive upon arrest or upon ascertainment of nationality. The Court
will address this issue latersccparagraph 63 below).

54. The Parties disagree as to what each of them must show as regards
nationality in connection withthe applicability of thterns of Article 36,
paragraph 1,and as to how the principles of cvidencehave been met on

the facts of the cases. AVENA ET AUTRES (ARRET) 40

obligations ne s'appliquent qu'aux personnes dont il a kt6 etabli qu'elles
etaient uniquement de nationalite mexicaineet non Bcellesposskdant i la

nCab) du paragraphc I dc I'articlc36,comptctcnu dc I'inlcrprktationqu'il
convient de donner de I'expression({sansretard)) utiliskedans cet alinia.

52. Par condquent, en ce qui concerne 1'alinCahJ du paragraphe 1de
I'arrjcle75,deux points majeurs sur lesquels les Parties s'opposent sont,
prernihement, la question de la nationalite des personnes concernkes,
deuxiimement, la question de la significationqu'il canvient de donner i
l'expressionrcsans retard>).La Cour examinera successivementchacun de
ccspoints.
53. Les Parties ont situt leursarguments rclatifs la nationalitt dans
trois conlexlesjuridiyues differents. LesEtats-Unis en ont en premier lieu
tire une exception d'irrecevabiliteque la Cour a dejjkexaminee (voir para-
graphes 41 et 42 ci-dessus).Par ailleursles Etats-Unis soutiennent qu'un
grand nombre des cinquante-deux personnes viskes au paragraphe IS ci-
dessus Ctaient des rcssortissants amkricains cl quc, par conskqucnt, lcs
Elals-Unis n'klaicnt lenus d'aucune obligation envers ces personnes en
vcrtu dc I'alinta hJ du paragraphe 1 de l'articl36. La Cour traitera de

cet aspccl dc la queslion dans les paragraphes qui suivent. EnGn, les
Parties divergent sur la qucstion dc savoir si l'information quidoit etre
donnie ({sansretard)), comme le prescrit l'alinia b) du paragraphe 1de
I'article 38, doic I'elrdts I'arrestation d'une pcrsonne ou a partir du
moment ou sa nationalit6 est etablie.La Cour se penchera sur cette ques-
tion plus loin (voirparagraphe 63 d-apres).
54. Les Parties ne sont d'accord ni sur ce que chacune d'elles doit
prouver en ce qui concerne la nationalilk aux tins de I'application du
paragraphe I de l'article35, ni sur la maniere dont lesprincipes regissant
la preuve ont 6tSrespectksdans chaque cas en ce qui concerne les faits. 55. Both Parties recognize the well-sellled principle in international
law that a litigant seeking to establish the existence of a fact bears the
burden of proving it (cf. Military und Pararniliiary Activilies in and
uguinst Niuarragncc(Nicaragua v. Uniied Slates ofAmericu), Jurisiliction
and Adwissisibility J,udgnzenl,I. C.J.Rpporls 1984, p. 437, para. 101).
Mexico acknowledges that it has the burden of proor to show that the
52persons listedin paragraph 16above were Mexicannationals to whom
Ihc provisions of Article36,paragraph 1(b), in principle apply.It claims
it hasmet this burden by providing to the Court I~C birth certificates of
these nationals, and declarations from 42 of them that they have not

acquired United States nationality. Mexico further contends that the
burden of proof lieson the United States should it wish lo contend that
particular arrested persons of Mexican nationality were, at the relevant
time, also United States nationals.

56. The United States accepts that in such cases it hasthe burden of
proof to demonstrate United States nationality, but ont tendsthat none-
thelessthe "burden of evidcnce" as to this remains with Mexico.This dis-
tinction is explained by the United States as arising out of the f:dctthat
persons of Mexican nationality may also havc acquired United States
citizenship by operation of law, depending on their parents' dates and
places or birth, places of residency, marital status at time of their birth

and so forth. I1the viewof the United States "virtually all such informa-
tion is in the hands of Mexico through the now 52 individuals it repre-
sents". The United Slates contends that it was the responsibility of'
Mexico lo produce such information, which responsibility ithas not dis-
charged.
57. Thc Court finds that it ISfor Mexicoto show that the 52 persons
listed inparagraph 16above held Mexicannationality at the time of their
arrest. Thc Court notes that to this end Mexico has produced birth
certificates and declarations of nationality, whose contents have not
been challenged by the United States,

The Court observes further that the United States has, however, ques-
tioned whether some of these individuals were not also United States

nationals. Thus, the United States has informed the Court that, "in the
case of defendant Ayala (case No. 2)we are close to certain that Ayala is
a United States citizen", and that this could be confirmed withabsolute
certainty if Mexico produced facts about this mattes. Similarly Mr.
Avena (case No. 1)was said to be "likely'90 be a United States citizen,
and there was "some possibility" that some 16 othcr defendants were
United States citizens.Asto six others, the United States said it "cannot
rule out the possibility" of United States nationality. The Courlakes the
viewthat it was for the United States to demonstrate that thiswas so and
to furnish the Court with all information on the matter in its possession.
In so far as relevant data on that matter are said by the United States to

lie within the knowledge of Mexico, itwas for the United States to have 1

sought that information from the Mexican authorities. The Court cannot
acceptthat, because suchinrormation may have bccn in part in the hands
of Mexico, it was for Mexicoto produce suchinformation. It was for the
United States to seek such information, with sufficient specificity,and to
demonstrate both that this was done and that the Mexican authorities
declined or failed to respond to such specific requests. At no stage,
however, has the United States shown the Court that it made specific
enquiries of those authorities about particular cascs and that rcsponses
were not forthcoming. The Court accordingly concludes that the United

Statcs has not mct its burden of proof in its attempt to show that persons
of Mexican nationality were also United States nationals.

The Court therefore finds that, as regards the 52 persons listed in
paragraph 16 above, the Unitcd Statcs had obligations under Article 36,
paragraph 1 (b).
58. Mexico asks the Court to find that

"the obligationin Article 36,paragraph I, of the Vienna Convention
requires notification ofconsular rights anda reasonable opportunity
for consular access before the competent authorities or the receiv-
ing State take any action potentially detrimental to the foreign
national's rights".

59. Mexicocontends that, i11each of the 52cases beforethe Court, the
United States failed to provide the arrested persons with information as
to their rights under Article 36, paragraph 1 (h), "without delay". It
alleges that in one case, Mr. Esquivel(case No. 7), the arresled person
was informed, but only some 18months after the arrest, whilein another,
that of Mr. Juirez (case No. lo), information was given to the arrested
person of his rights some 40 hours after arrest. Mexicocontends that this
still constituted violation, because "without delay" is to be understood
as meaning "immediately", and in any event before any interrogation
occurs. Mexico further draws the Court's attention to tlze fact that in
this case a United States court found that there had been a violation of

Article 36, paragraph 1 (b), and claims that the United States cannot
disavow such a determinatioil by its own courts. In an Annex to its
Memorial, Mexicomentions that, in a third case (Mr. Ayala, case No. 2),
the accused was informed of his rights upon his arrival on dcath row,
some four years after arrest. Mexico contends that in the remaining
cases the Mexicans concerned were in fact never so informed by the
United States authorities.

60. The United States disputes both the facts as presented by Mexico
and the legalanalysis of Article36, paragraph 1 (b), of the Vienna Con-
vention offered by Mexico. The United States claims that Mr. Solache

(case No. 47) was informed of his rights under the Vienna Conventionsiondu Mexique,lesEtats-Unis dcvaicnts'enenquerir aupris des autorites
mexicaines.La Cour nepeut pas acceplcrI'argument selon lequeillrevenait
au Mexique de produire ces informations au motif qu'ellesse trouvaient

de chercher iiobte~lirlesdilesinrormations, avecun degrede precisionsuf-

some sevenmonths after his arrest.The United States further claimsthat
many of the persons concernedwereof United States nationalityand that
at leastsevenof these individuals"appear to have affimativcly claimedto
be United Statescitizensat the timeof their arrest". Thesecases were said
to be those of'Avena (case No. l), Ayala (case No. 21,Benavides (case
No. 3), Ochoa (caseNo. 18),Salcido(caseNo. 22),Tafoya (caseNo. 241,
and Alvarez(case No. 30).In the viewof the United States no duty of

consular information arose in these cases.Further, in the contention of
the United States, in the casesofr*Ayala (caseNo. 2)and Mr. Salcido
(caseNo. 22)there wasno reasonto believethat the arrested personswere
Mexicannationals at any stage; the informationin the caseof Mr. Juirez
(cascNo. 10)was given"without delay",
51. The Court thus nowturns to the interpretation of Article 36,para-
graph 1 (b), having found in paragraph 57above that it isapplicable to
the 52persons listedin paragraph 16.It beginsby noting that Article 36,
paragraph 1 (b), contains three separate but interrelated elements: the
right of thc individual concerned lo be informed without delay of his

and the obligation of the receivingState to forward without delay any
communication addressed to the consular post by the detained person.

62. The third element of Articlc 36, paragraph 1 (b), has not been
raisedon the facts beforethe Court. The Court thus begins withthe right
of an arrested or detained individualto information.

63. The Court finds that the duty upon the detaining authoritiesto
givethe Article 36, paragraph 1 (b), information to the individualarises

either legallyor illegally,on its territory, and moreover that its lawscon-

cerning citizenship are generous. The United States has also pointed out
that itis a mullicuItura1society, wilh citizenshipbeing heldby pcrsons of
diverse appearance, speaking many languages. The Courl appreciates
that in the United States the language that a person speaks, or his
appearance, does not ncccssarily indicate that hc is a foreign national.
Nevertheless, and particularly in view of the large numbers of foreign
nationals living in the United States, lhcse very circumstances suggest
that it would be desirable for enquiry routinely to be made of the indi-
vidual as to his nationality upon his detention, so that the obligations of
the Vienna Convention may be complied with. The United Stales has
informed the Court that some of'its law enforcement authorities do
routinely ask persons lakcn into detention whether they are United States
citizens. Indccd, were each individual to be told at that time that, should
hc be a foreign national, hc is entitled to ask for his consular post to be

contacted, compliance with this requirement under Article 36, para-
graph 1 (h), would be greatly enhanwd. The provision of such informa-
tion could parallel the readingof'those rights of which any person taken
into custody in connection with a criminal offcnce must be informed
prior to interrogation by virtue of what in thc United States is known as
the "Miranda rule"; these rights include, inleraliu, the righl to remain
silent, theright to have an attorney present during questioning, and the
right tohave an attorney appointed at government expense if the person
cannot afford one. The Court notes that, according to the United States,
such a practice in respect of the Vienna Convention rights is already
being followed in some local jurisdictions.

65. Bearing in mind the complexities explained by the United States,
the Court now begins by examining the application of Article 36,
paragraph I (b), of the Vienna Convention to the 52 cases. In 45 of
these cases, the Court has no cvidence that the arreslcd persons claimed
United SVdtesnationality, or wercreasonably thought to bc United States

nationals, with specific enquiriesbeing made in timely fashion to verify
such dual nalionality. The Court has explained in paragraph 57 above
what enquiries it would have expectedto have been made, within a short
time period, and what information should have been provided to the
Court.
66. Seven pcrsons, however, are asserted by the United States to
have stated at the timc of arrest that they were United States citizens.
Only in the casc of Mr. Salcido (casc No. 22) has the Court been pro-
vided by the United States with cvidenceof such a statement. This has
been acknowledged by Mexico. Further, there has been no cvidence
before thc Court to suggest that there were in this case at the same time
also indications of Mexican nationality, which should have caused
~apidenquiry by the arresting authorities and the providing of consular
information "without delay". Mexico has accordingly not shown that in1 Mexiquc n'a donc pas dcmonlrt que les Etats-Unis aient viol&les obli-

Etats-Unis estM. Alvarez (casno30),qui a ttCarrttC au Texasle 20juin
1998. Les registresdu Texas le designentcomme citoyen desEtats-Unis.
i Dans les trois jours qui ont suivison arrestation, les autoritks du Texasinlbrmed that the Tmmigrationand Naturalization Service was holding
investigations to determine whether, because of a previous conviction,
Mr. Alvarez was subjcctto deportation as a foreign national. The Court
has not been presented with evidencethat rapid resolution was sought as
to the question of Mr. Alvarez'snationality.

74. The Court concludes that Mexico has failed to prove the violation

by the United States of its obligationsundcr Article 36,paragraph 1 (b),
in the caseor Mr. Salcido (case No. 22),and his casewill not be further
cornmenlcd upon. On the other hand, as regards the other individuals
who are alleged to have claimed United States nationality on arrest,
whose cases have beenconsidered in paragraphs 67 to 73 above, the
argument or lhc UnitcdStates cannot be upheld.

75. The question noncthcless remains as to whether, in each of the 45
cases referredto in paragraph 65 and of the sixcases mentioned in para-
graphs 67 to 73, the United States did provide the required information
to the arrested persons "without delay". Itis to that qucstion that the
Court now turns.

76. Thc Court has been provided with declarations from a number of
the Mexican nationals concerned that attest to their never beinginformed
of their rights under Article6,paragraph 1 (b). The Court at the outset
notes that, in 47 such cases, the United States nowhere challenges
this fact of information not being given. Nevertheless, in the case of
Mr. Hernindez (case No. 34),the United States observes that

"Although the [arresting] officerdid not ask Hernindez Llanas
whether he wanted them to inform the Mexican Consulate of his
arrest, it was certainly not unreasonable for him to assume that an
escaped convict would not want the Consulate of the country from
which he escaped notifiedof his arresl."

Thc Court notes that the clear duty to provide consular information
under Article 36, paragraph 1 (B), does not invite assumptions as to
what the arrested person might prefer, as a ground For not informing
him. It rather givesthe arrested pcrson, once informed, the righto sayhe
nonetheless does not wish his consular post to be notified.It necessarily
rollowsthat in each of these 41 cases, the duty to inform "wilhout delay"
has been violated.

77. In four cases, namely Ayala (caseNo. 2), Esquivel (caseNo. 7),
Juirez (caseNo. 10)and Solache (caseNo. 471, some doubtsremainas to
whether the information that was givenwas providcd without delay. For

these, some examination of the tern isthus necessary.

78. This is a matter on which the Parties have very different views.avaient cependant Ctkinformkes des recherches du servicede l'immigra-

no 47), des doutes subsistent quant a la question de savoir si l'informa-
tion donneel'a it6 sans retard. A cette finlconvientdonc de preciser le

sens de cette expression.
78. I1s'agitd'uncqucstion surlaquelle lesParties ont des vues trksdif-According to Mexico, the timing of the notice to the detained person "is
critical to the exercise of the rights provided by Article 36"andthe
phrase "without delay" in paragraph 1 (hj requires "unqualified imme-
diacy". MexicoI'urthercontcnds that, in viewof the object and purpose
of Article 36which is to enable "meaningful consular assistance" and the
safeguarding of the vulnerability of foreign nationals in custody,

"consuiar notification. . .must occur immediately upon detention
and prior to any interrogation of the foreign detainee, so that the
consul may offcr useful advice about the foreign legal system and
pravide assistance inobtaining counsel before the foreign national
makes any ill-informeddecisionsor the State takes any action poten-
tially prejudicial to his rights".

79. Thus, in Mexico'sview,it would followthat in any case in which a
foreign national was interrogated before being informed of his rights
under Article 36, there would @so facto be a breach of that Article, how-
everrapidly after the interrogation the informationwas given to the for-
eign national. Mexicoaccordingly includes the case of Mr. Juirez among
those where it claims violation of Article6, paragraph 1 (b), as he was
interrogated before beinginformed of his consular rights, some40 hours
after arrest.

80. Mexico has also invoked the dravnnxpr6purutoires or the Vienna
Convention in support of its interpretation of thcrequirement that the
arrested person be informed "without delay" of the right to ask that the
consular post be notified. In particulaMexico rccallcd that the phrase

proposed to the Conferenceby the International Law Commission, "with-
out undue delay", was replaced by thc United Kingdom proposal to
delete the word "undue". The United Kingdom representative had
explained that this would avoid the implication that "some delay was
permissible" and no delegate had expressed dissent with the USSR and
Japanese statements that the result of the amendment would be Eo
require information "immediately".

81. The United States disputed this interpretation of the phrase "with-
out delay". In its viewit did not mean "immedialely, and before interro-
gation" and such an understanding was supported neither by the termi-
nology, nor by thc object and purpose of the Vienna Convention, nor by
its travaux pr&paruloires.In the booklet referred to in paragraph 63
above, the State Department explains that "without delay" means "there
should be no deliberate delay" and that the required action should be

taken "as soon as reasonably possible under the circumstances". It was
normally to be expected that "notification to consular officers" would
have been made "within 24 to 72 hours ofthe arrest or detention". The
United States further contended that such an interpretation of the words
"without delay" would be reasonable in itself and also allow a consistent AVENA ET AUTRES (ARR~T) 47

interpretation of the phrase as it occurs in each of three different occa-
sions in Article 36, paragraph 1 (h). As fbr the truvous prkparrrtoires,
they showed only that unduc or dclibcratc dclay had been rcjcctcd as
unacceptable.

82. According to the United States, the purpose of Article 36 was to
facilitate the exerciseof consular functions by a consular officer:
"The significanceof'giving consular inlbrmalion to a national is
thus limited .. . It is a procedural device that allows the foreign
national to trigger the related process of notificatio. . [It] cannot
possibly befundamental to the criminal justice process."

83. The Court now addresses the question of the proper interpretation
of the expression "without dclay" in thelight of arguments put to it by
the Parties. The Court begins by noting that the precise meaning of
"without delay", as it is to be understood in Articl35, paragraph 1 (b),

is not defined in the Convention. This phrase therefore requires interpre-
tation according to the customary rules of treaty interpretation refleclcd
in Articles 31 and 32 of the Vienna Convention on the Law ot'Treaties.

84. Article I of the Vienna Convention on Consular Relations, which
defines certain of the terms used in the Convention, offers no definition
of the phrase "without delay". Moreover, in the different language ver-
sions of the Convention various terms are e~nployedto render the phrases
"without delay" in Article 36and "irnmedialely" in Article 14.The Court
observes that dictionary definitions, in thc various languages of the
Vienna Convention, ok'f'eriverse meanings of the tcrm "without dclay"

(and also of "immediately"). It is therefore necessary lo look elsewhere
for an understanding of this term.

85. As for the object and purpose of the Convention, the Court
observes lhalArticle 36 provides for consular officers to be free to com-
municate with nationals of thc scnding State, to have access to them, to
visit and speak with them and to arrange for their legal representation. It
is not envisaged, either in Article 36, paragraph 1, or elsewhcrc in the
Convention, that consular functions entail a consukar officer himselfor
herself acting as the legal representative or more directly engaging in
the criminal justice process. indeed, this is confirmed by the wording of
Artide 36, paragraph 2, of the Convention. Thus, neithcr thc lcms
of the Convention as normally understood, nor its object and purpose,

suggest that "without delay" is to be understood as "immediately upon
arrest and before interrogation".

86. The Court further notes that, notwilhslanding the uncertainties in
the travuzrxprkpuraloires, they too do nor support such an interpreta-tion de I'expression({sansretard )>est en elle-mime raisonnable et perrnet
en outre une interpretation homogkne de l'expressiondans trois passages

I'arrestation et avant l'interrogatoireb.
86.La Cour rclkve en outre que, quellesque soient lesincertitudes dcs
travaux prepara~oires, ceux-ei ne viennent pas davantagc ktayer cette tion. During the diplomatic conf'crence,the conference's expert, former
Special Rapporteur of the International Law Commission, explained to
the delegatcs that the words "without undue delay" had bcen introduced
by the Commission, after long discussion in both the plenary and draft-
ing committee, to allow for special circumslanccs which might permit
information as to consular notification notlo be givenat once. Germany,
the only one of two States to present an amendment, proposed adding
"but at latest withinone month". There was an extended discussion by
many different delegates as to what such outer time-limit would be
amptable. During that debate no delegate proposed "immediately". The
shortest specific period suggested was by the United Kingdom, namely
"promptly" and no later than "48 hours" afterwards. Eventually, in the
absence of agreement on a precise time period, the United Kingdom's

other proposal to delete the word "undue" was accepted as the position
around which delegatescould converge. It isalso of interest that there is
no suggestion in the travaux that the phrase "without delay7'mighthave
different meanings in each of the three sets of circumstancesin which itis
used in Article 36, paragraph 1 (bJ.

87. The Court thus finds that "wizhout delay" is not necessarily tobe
intcrprcted as "immediately" upon arrest. It further observes that during
the Conference debates on this term, no delegate made any connection
with the issue of interrogation.hc Court considers that the provision in
Article 36, paragraph I (b), that the receiving Stale authorities "shall
inform the person concerned without delay of his rights" cannot be intcr-
. preted to signifythat the provision of such information must necessarily
precede any interrogation, so chat the commencement of interrogation
before the information is given would be a breach of Article 36.

88. Although, by application of the usual rulesofin~erpre~ation,"with-
out delay" as regards the duty to inform an individual under Article 36,
paragraph 1 (b), is not to be understood as necessarilymeaning "irnrnc-

diately upon arrest", there is nonetheless a duty upon the arresting
authorities.to give that information to an arrested person as soon as it is
realized that the personisa foreign national, or once therare grounds to
think that the person is probablya foreign national.

89. With one exception, no information as to entitlement to consular
notification was given in any of the casescited in paragraph 77 within
any ofthe various time periods suggested by the delegatesto the Confer-
ence on the Vienna Convention, or by the United States itself (see para-
graphs 81and 86above). Indeed, the information was giveneither not at
allor at periods very significantlyremoved from the time of arrest. the

consular rights 40 hours after his arrest. The Court notes, however, that
Mr. Juirez? arrest report statedthathe had been born in Mexico; more-
over, therehad been indicationsof his Mexicannationality from thc time
of his initial interrogationy agents of the Federal Bureau of Investi-
gation (FBI) Lbllowinghis arrest. It EoIlowsthat Mr. Juiirez'sMexican
nationality was apparent from the outset of his detention by the United
Statesauthorities. In these circumstances, in accordance with its interpre-
tation of the expression "without delay" (see paragraph 88 above), the
Court concludes that theUnited States violated the obligation incumbcnt
upon it under Article36, paragraph 1 (BJ,to inform Mr. Juarez without
delay of his consular rights. The Court notcs that the same finding was

reached by a California Superior Court, albeit on different grounds.

90. The Court accordingly concludes that, with respect to each of the
individualslistedin paragraph 16,with the exception of Mr. Salcido (case
No. 22; see paragraph 74 above),the United Stateshas violaled its obli-
gation under Article 36, paragraph 1 (b), of the Vienna Convention to
provide information to the arrested person.
91. As noted above, Article 36, paragraph I (b), contains three
elements. Thus far, the Court has bccn dealing with the right of an
arrested person tobe informed that he may ask for his consular post lo
be notified. The Court now turns to another aspect of Article 36,
paragraph 1 (h), The Court finds the United States is correct in observ-
ing that the fact that a Mexican consular post was not notified under
Article 36, paragraph 1 (151does not of necessityshow that the arrested
person was not inlbm~edof his rights under that provision. He may

have been informed and declined to have hisconsular post notified.Thc
givingof the information is relevant, however, for satisfying the clement
in Article36, paragraph 1 (A) ,n which the other two elements thcrcin
depend.

92. In only two caseshas the United States claimed that the arrested
person was informed or hisconsular rights but asked for the consular
post not to be notified. These arMr. luirez (case No. 10)and Mr. So-
lache (case No. 47).
93. The Court is satisfied that whcn Mr. Juirez (case No. 10)was
informed of his consular rights 40 hours after his arrest (see para-
graph 89) he chose not to have his consular post notified. As regards
Mr. Solache(caseNo. 471,however, itis not sufficientlyclcar to the Court,
on the evidencebefore it, that he requested that hisconsular post should
not be notified.Indeed, the Court has not been provided withany reasons

as to why, if a request of non-notification was made, the consular post
was then notifiedsome three months latcr.

94. In a further three cases, the United States alleges that the con-
sular post was formally notifiedof the detention of one of its Mexican51 AYENA AND OTI4ERS(JUDGMENT)

nationals without prior information to the individual as to his consular
rights.These are Mr. Covarrubias (case No. 6), Mr. Hernandez (case
No. 34) and Mr. Reyes (case No. 543.The United States further con-
tends that the Mexicanauthorities were contacted regarding the case of
Mr. Loza (caseNo. 52).
45. The Court notes that, in the case of Mr. Covarrubia(caseNo. 61,
the consular authorities learned from third parties of his arrest shortly
after it occurred.Some 16 months later, a court-appointed interpreter
requested that the consulate intervene in the case prior to trial. It would
appear doubtrul whether an interpreter can be considered a competent
authority for triggering theinterrelated provisions of Article, para-
graph 1 (b), of the Vienna Convention. In the caseofMr. Reyes (case
No. 54), the United States has simply told the Court that an Oregon

Department of Justice attorney had advised United States authorities
that both the District Attorney and the arresting detective advisedhe
Mexicanconsular authorities of his arrest. No information is givenas to
when this occurred, in relation to theate of his arrest. Mr. Reyes did
receiveassistance beforehis triaIn these two cases,the Court considers
that, evenon thehypothesisthat the conduct of the United Stateshad no
serious consequencesfor the individuals concerned, it did nonetheless
constitutea violation of the obligations incumbent upon the United
States under Article36, paragraph I (h).

96. In the case of Mr. Loza (case No. 523,a United States Congress-
man from Ohio contacted the Mexican Embassy on behalf of Ohio
prosecutors, some four months after the accused's arrest, "to enquire
about the procedures for obtaininga certified copyof Loza's birth cer-
tificate". The Court hasot been provided witha copy of the Congress-
man's letter and is therefounable to ascertain whether itexplained that

Mr. Loza had been arrested. The response from the Embassy (which
is also not included in the documentation provided to the Court) was
passed by the Congressman to the prosecuting attorney, who then asked
the Civil Registry of Guadalajara for a copy of the birth certificate.
This request made no specificmention ofMr. Loza'sarrest. Mexicocon-
tends that its consulate was neverformally notifiof Mr. Loza'sarrest,
of which it only became aware after he had been convicted and
sentenced to death. Mexico includesthe case of Mr. Lord among those
in which the United States was in breach of its obligation of consular
notification. Taking amount of all these elements, and in particular
o€ the fact that the Embassy was contacted four months after the
arrest, and that the consular post became aware of the defendant's
detention only after hc had been canvicted and sentenced, the Court
concludes that in the caseof Mr. Loza the United States violated the
obligation ol' consular notification without delay incumbent upon it

contactke quatre mois apri-s l'arrestation et que Ie poste consulaire n'a

Unisont violCI'obligation denotification consulaire sans retard qui Ieur

15 Octobcr 1997.The United States authorities had no reason to believe
he might have American citizenship.The consular post was notified the
followingMonday, that isfivedays (corresponding to only threc working
days) thereafter.The Court finds that, in the circumstances, lhc United
Statcs did notify the consular post without delay, in accordanw with its

obligation under Article 36, paragraph 1 (h).

88. In the first of its final submissions, Mexico also asks the Court
to find that the violations it ascribes to the United States in rcspect of
Article 36, paragraph 1 (h), have also deprived "Mexico of its right to
provide consular protection and the 52 nationaldright to receive such
protection as Mexico would provide under Article 36 (1) (a) and (c)
of thc Convention".

99. The relationship between the three subparagraphs of Article 36,
paragraph 1, has been described by the Court in its Judgment in
the LaCrund case (I.C.J. Reporr~ 2001, p. 492, para. 74) as "an
interrelated r6gime". Thc legal conclusions to bc drawn from that

interrelationship necessarily depend upon the facts of each case. In the
LaGrund case, the Court found that the failure for 16 years lo inform
the brothers of their right to havc their consul notified effcclively pre-
vented the exercise of other rights that Germany might have chosen to
exerciseunder subparagraphs (a) and (cj.
100. Ilisnecessaryto revisitthe interrelationship of the three subpara-
grnphs of Article 36, paragraph 1,in the lighl of the particular facts and
circumstances of the prcsentcase.
101. The Court would first recall that, in the case of Mr.Juhrez (case
No. 10) (seeparagraph 93 above), whcn the defendant was ialbrmcd af
his rights, he declinedto have hisconsular posznotilicd. Thus in this case
lhere was no violation of either subparagraph la)or subparagraph (c)
of Article 36,paragraph 1.
102. In the remaining cases,because of the failure of the United States

to acl in conformity with Article 36, paragraph I (b), Mexico was in
effect prccluded (in some cases totally,and in some cases for prolonged
periods of time) from exercisingits right under paragraph 1 (a) to com-
municate with its nationals and have accessto them. As the Court has
already had occasion to explain, il is immaterial whether Mexico would
have offered consular assistance, "or whether a different verdict would
have been rendered. It is sufficient that the Convention conferred these
rights" (I.CX Reporrs2001, p, 492, para. 74),which might havc been
acted upon.
103. The same is true, pari pcr.rsu,of ccrtain rights identified in sub-
paragraph (c): "consular officers shall havethe right to visit a national
or the sending State who is in prison, custody or detention, and to con-

verse and correspond with him . ..". 97. M. Hernilndez (cas no 34) a ite arrete au Texas le tnercredi

penser qu'ilaurait pu avoir la ciloyennetkamkricaine. Le poste consulaire

paragraphe 1 de l'article 36.

qu'une notification soit adresske h son poste consulaire. I1n'y a dkslors

104.On the other hand, and on the particular facts of this case, no
such generalized answer can he given as regards a further entitlement
mentioncd in subparagraph (c), namely, the right ofconsular officers"to
arrangc for [the]legalrepresentation" of the foreign national. Mexico has
laid muchemphasis in this litigation upon the importance of consular
officersbeing able lo arrange for such representation before and during

trial, and especiallyt sentencing, in cases in which a severepenalty may
be imposed. Mexicohas further indicated thc importance of any financial
or other assistance that consular officersmay provide to defcncecounsel,
intcr aliu for investigationof the defendant's familybackground and
mcntal condition, when such information is relevant to the casc. The
Court observes that the exerciseof the rights or the sending State under
Article36, paragraph 1 (c), depends upon notification by the authorities
of the receiving State.t may be, however, that information drawn to the
attention of the sending State by other means maystill enable itsconsular
officers to assist in arranging legal representation Tor its national. In
the following cases, the Mexican consular authorities learned of their
national's detention in time to provide such assistance, eithcr through

notification by United States authorities (albeit belatedly in terms of
Article 36, paragraph 1 (h)) or through other channels: Renavides
(case No. 3);Covarrubias (case No. 6); EsquiveI (case No. 7); Hoyos
(case No. 9); Mendoza(case No. 17); Ramirez (case No. 20); Sanchez
(case No. 23); Verano (case No. 27); Zamudjo (case No. 29); Gomez
(case No. 33); Hernindez (case No. 34); Ramires (case No. 41); Rocha
(case No. 42); Solache (caseNo. 47); Carnargo [case No. 49) and Rcyes
(case No. 54).

105. In relation to Mr. Manriquez (case No. 14), the Court lacks pre-
cise information as to when his consular post was notified. It is merely
given to understand that it was two years prior to conviction, and that
Mr. Manriquez himself had never been informed of his consular rights.

There is also divergence between the Parries in regard to the case of
Mr. Fuentes (caseNo. 15), where Mexico claims it became aware of his
detention during trial and the United States says this occurred during
jury selection, prior to the actual commencement of the trial. In thc
case of Mr. Arias (case No. 44, the Mexican authorities became aware
of his detention less than one week before the commencement of the
trial. Inthose three cases, the Court concludes that the United States
violated its obligations under Article 36, paragraph 1(c).

106. On this aspect of the case, the Court thus concludes:

(1) that the United States committed breaches of the obligation incum-

bent upon it under Article 36, paragraph 1 (b), of the Vienna Con-
vention to inform detained Mexican nationals or their rights under AVENA ET AUTRES (ARRET) 54

107. In its third final submission Mexicoasks the Court to adjudge
and declarethat

"the United Statesviolated its obligationsunder Article 36 (2)of the
Vienna Convention by failing to provide meaningful andeffective
reviewand reconsideration ofconvictionsand sentences impairedby
a violation of Article 36 (I)".

108. Article 36, paragraph 2, provides :
"The rights referred to in paragraph 1of this article shallbe exer-

cised in conformity with the laws and regulations of the receiving
State, subject to the proviso, however,that the said lawsand regu-
lations must enable full effectlo be given to the purposes for which
thc rightsaccorded under this articleare intended."

109. In thisconnection, Mexico has argued that the United States
"Byapplyingprovisionsof itsmunicipal lawto defeat or foreclose
remedies forthe violation of rights conferred by Article 36 - thus
failingto provide meaningful review and reconsideration of severe

sentencesimposed in proceedings that violated Article 36- ... has
violated, and continues to violate, the Vienna Convention."

More specifically,Mexicocontends that:

"The United States uses several municipallegal doctrines to pre-
vent finding any legal effect from the violations of Article 36.First,
despitethis Court'sclear analysisin LuGrand,US courts, at both the
state and federal level,continue to invoke default doctrines to bar
any review of Article 36 violations - even when the national had

been unaware of his rights to consular notification and communica-
tion and thus his abilityto raise their vioIation as an issue at trial,
due to the competent authorities' failureto comply with Article36."

110. Againstthis contention by Mexico,the United States arguesthat:

"the criminal justice systems of the United States address all errors

110. A cela, les Etals-Unis repondent que:
<<les systemesde justice penaie des Etats-Unis permettent l'exarnen in process through both judicial and executive clemencyproceed-
ings, relyingupon the latter when rulesof default haveclosedout the
possibility of the former. That is, the 'laws and regulations' of the
United States provide for the correction of mistakes that may bc
relevant to a criminal defendant to occur through a combination
of judicial review and demcncy. These processes together, working
with other competent authorities, give fulleffst to the purposes for
which Article 36 (1) is intended, in conformity with Article 36 (2).

And, insofar as a brcach of Article 36 (1) has occurred, these pro-
cedures satisfy the remedial function of Article 38 (2) by allowing
the United States to provide review and reconsideration of convic-
tionsand sentences consistent with La Grrrrzd."

111. The "procedural default" rulc in United States law has already
bccn brought to the attention of the Court in the LaCrundcase. The fol-
lowing brief definitionof the rulewas provided by Mexico in its Mcmo-
rial in this case and has not been challenged by Ihc United States: "a
defendant who could have raised, but failsto raise,a legal issueat trial
willgenerally not be permitted to raise it in future proceedings,on appeal
or in a petition for writ of huheas (:orpus".The rule requires exhaustion
of remedies, inter ulirral lhc statc level and before a Izuheascorpus
motion call be filed with federal courts. In the LaGrandcase, the rule in
question was applied by United Stales federal courts; in the present case,
Mexico also complains of the application of the rulc in certain state

courts of criminal appeal.

112. The Court has alrcady considered the application of the "pro-
cedural default" rule, alleged by Mcxico to be a hindrance to the full
implementation of the international obligations of the United States
under Article 36,in the LaGrandcase, when the Court addressed the issue
of its implicationsfor the application of Article 36,paragraph 2, of the
Vienna Convention. The Court emphasized that "a distinction must be
drawn between that rulc as such and its specificapplication in the present
case". The Court stated:

"In itself, the rule does not violate Articl36of the Vienna Con-
vention. The problem arises when the procedural default rule does
no1allow the detained individual to challenge a conviclion and sen-
tence by claiming,in reliance on Article36,paragraph 1,of the Con-
vention, that the competent national authorities failed to comply
with their obligation to provide the requisite consular information
'without delay',thus preventing the person from seekingand obtain-
ing consular assistance from the sending State." (I.CJ. Reports

par. 90.)57 AVENA AND OTI.IERS(JUDGMENT)

On this basis, the Court concluded that "the procedural default rule
prevented counsel Forthe LaGrands to effectivelychallenge their convic-
tions and sentences other than on United States constitutional grounds"
(I.C.J. Reports 2001, p. 493, para. 91).This statement of the Court seems
equally valid inrclation lo the present case, where a number of Mexican
nationals have been placed exactlyin such a situation.

113. The Court willreturn to this aspect below, in the context of Mexi-

co'sclaims as to remedies. For the moment, the Court simply notes that
the procedural default rule has not been revised, nor has any provision
been made to prevent its application in cases where it has beenIhe failure
of the United States itself to inform that may have precluded counsel
from being in aposition to have raised the question of a violation of the
Vienna Convention in the initial trial. It thus remains the casc that the
procedural default rule may continue to prevent courts from attaching
legal significancetothe fact, inter uliu, that the violationthe rights set
forth in Article 36, paragraph 1, prevented Mexico, in a timely fashion,
from relaining privatccounsel for certain nationals and otherwise assist-
ing in their defence. In such cases, application of the proceduraldefault
rule would havethe effect of preventing "full effect[from being] givento
the purposes Forwhich the rightsaccorded under thisarticleare intended",

and thus violate paragraph 2 of Article 36.Thc Court notes moreover
that in several of the cases cited in Mexico's final submissions the pro-
cedural default rule has already been applied, and that in others it could
be applied at subsequent stages in the proceedings. However, in none of
the cases, savefor the three mentioned inparagraph 114 below, have the
criminal proceedings against the Mexican nationals concerned already
reached a stage at wh~chthere is no further posnbility of judicial re-
examination of those cases;that isto say, all possibilityisnot yet excluded
of "review and reconsideration" of conviction and sentence, as called for
in the LaCrandcase, and as explained further in paragrslphs 128 and fol-
lowing below. It would therefore be premature Forthe Court to concludc
at this stage that,inthose cases, there is alreadya violation of thc obli-
gations under Article 36, paragraph 2, of the Vienna Convention.

114. By contrast,the Court notes that in the case of three Mexican
nationals, Mr. Fierro (case No. 311,Mr. Moreno (mse No. 391,and
Mr. Torres (case No. 53),conviction and scntence have become final.
Moreover, in the case of Mr. Torres the Oklahoma Court of Criminal
Appeals has set an execution date (see paragraph 21 above, in Jne).
Thc Courtmust therefore conclude that, in relation to these three indi-
viduals, the United States is in breach of the obligations incumbent
upon it under Article 36, paragraph 2, of the Vienna Convention. Sur cettebase,la Cour a concluque ((lareglede lacarence prockdurale

cace,si ce n'est sur la base du droit constitutionnel des Etats-Unis, leurs

cution (voirparagraphe 21 injine ci-dessus).La Cour doitdonc conclure
que, a l'kgardde ces trois personnes, lesEtats-Unis ont viol6les obliga-
tions leur incombant en vertu du paragraphe 2 de I'article 36 de la

convention de Vienne.58 AVENA AND OTHERS (JUDGMENT)

115. Having concluded that in most of the cases brought before the
Court by Mexico in the 52 instances, there has been a failure to observe
the obligations prescribed by Article 36, paragraph I (b], of thc Vienna
Convention, the Court now proceeds to the examination of the legal
consequences or such a breach and of what legal remedies should be con-
sidered for the breach.
116. Mexico in its fourth, fifth and sixth submissionsasks theCourt lo

adjudge and dcclare:
"(4) that pursuant to the injuries sufl'eredby Mexico in its own right
and in the exercise of diplomatic protection of its nationals,
Mexico is cntitled to Full reparation for these injuries in the
form of resriiutio i~?inlegrum;

(5)that this restitution consists of the obligation to restore the
status guu unlr by annulling or otherwise depriving of full
force orcfSectthe conviction and sentences of all 52 Mexican
nationals; [and]

(6) that this restitution also includes the obligation to take
all measures necessary to ensure that a prior violation of
Article 35 shall not aKcctthe subsequent proceedings."

117. In support of its fourth and fifth submissions,Mexicoargues that
"lt is wdl-established that the primary form of reparation available to a
State injured by an internationally wrongful act is rrstirutiin intrgrum",
and that "Thc United States is therefore obliged to take the necessary
actlon to restore the srarus quo ante in respect of Mexico's nationals
detained, tried, convicted and sentenced in violation of their intcrnalion-
ally recognized rights." To restore thestatus quo ante, Mexico contends
that "restitution hcrcmust take the form of annulment OFthe conv~ctions
and sentences lhat resulted from the proceedings tainted by the Article 36

violations", and that "It follows from the very nature of rrstilutiothat,
when a violation of an international obligation is manifested in a judicial
act, that act must be annulled and thereby deprived of any force or effect
in the national legal system." Mexico therefore asks in its submissions
that the convictions and sentences of the 52 Mexican nationals be
annulled, and that, in any Suturc criminal proceedings against these 52
Mexican nationals, evidence obtained in breach of Article 36 of the
Yicnna Convention be excluded.

118. The United States on the other hand argues:
"LaCrmrds holding calls for the United States to provide, in each
case, 'review and reconsideration' that 'takes account of the viola- tion, not 'reviewand reversal', not across-the-board exclusions of

evidence or nullification of convictions simply becausea breach of
Article36 (1)occurredand without regard to its effcctupon the con-
viction and sentence and, not .. .'a precise,concrete, stated result:
to re-establish theslutusquo ante"'.

119. The general principleon the legal consequencesof thecommis-
sion of an inlcrnationally wrongful act was stated by the Permanent

Court of International Justicein theFactory ut Chorrbwcaseas follows:
"It is a principle ofinternational law that the breach of an engagement
involves an obligation to make reparation in an adequate form." [FCLC-
tory at Chorzdw, Jurisdiction, 19.27,P.C.I.J., Series A, No. 9,p. 21 .)
What constitutes"reparation in an adequate form" clearly variesdepend-
ing upon the concrete circurnstanws surrounding each case and the pre-
cisenature and scope of the injury, sincethe question has to beexamined
from the viewpoint of whatis the "reparation in an adequate form" that
corresponds to the injury. Pna subsequent phase of the same case, the
Permanent Court went on lo elaborate on this point as follows:

"The essential principlecontained in Iheactual notion of an illegal
act - a principle which seems to be established by international
practice and in particularby the decisionsof arbilral tribunals - is
that reparation must, as far as possible, wipeout all the conse-
quences ofthe illegalact and reestablish the situation whichwould,
in all probability, have existedif that act had not been committed."
(Factory al Chorzdw, Meriis, 1928, P.C.I.J., Series A, No. 17,
p. 47.)

120. In the LaGrand case the Court made a general statement on the
principle involvedas follows :
"The Court considersin this respectthat ifthe United States, not-
withstanding its comrnitrncnt [to ensure implementation of the

specific measuresadopted in performalice of its obligations under
Article 36, paragraph 1 (b)], should fail in its obligation of consular
notificationto the detrimentof German nationals, an apology would
not sufficein cases wherethe individuals concerned have been sub-
jected to prolonged detention or convicted and sentenced to severe
penalties.In the case of such a conviction and sentence, itwould be
incumbcnt upon the United Slates to allow the reviewand reconsid-
eration of the conviction and sentenceby taking account of the vio-
lation of the rights set forth in the Convention. This obligation can
be carried out in various ways.The choice of n-reansmust be left lo
the United States." (LC J. Reporis 2001, pp. 513-514,para. 125.)

121. Similarly. in the present case:the Court's task is to determine
what would be adequate reparation for the violations of Article 36. It
should be clear from what has been observedabove that the internation-
ally wrongful acts committed by the United Stales were the failure of its violation,et non pas ccunrkexamen et une infirntationn, ni une ex-
clusion gknkraledes dements de preuveouI'annulation de la condam-

C.P.J.I. strie A a" 17, p. 47.)

120. Dans l'affaire LaGrand,la Cour a fait la declaration gCnCralesui-
vante au sujet du principe en jeu :
ciLa Cour cstime a cet egard que, si Ics Etats-Unis, en dCpit de

verses fa~ons. Le choix des moyens doit revenir aux Etats-Unis.))
(C.I.J. Recueil2001',p. 513-514,par. 125.)

121. De la m2me maniire, dans la prksente esptce, il s'agit de deter-
miner quelle serait la riparation adkquate des violationsde l'article 36. I1

tionalement illicites des Etats-Unis consistent en ce que leurs autoritks50 AVENA AND OTlIERS (JUDGMENT)

competent authorities to inform the Mexican nationals concerned, to
notify Mexican consular posts and to enable Mexico to provide consuIar
assistance. It follows that the rerncdy to make good lhese violations
should consist in an obligation on thc United States to permit reviewand
reconsideration of these nationals' cases by the Uniled States courts, as
the Court will explain further in paragraphs. 128 ta 134below, with a
view lo ascertaining whether in each case the violation of Article 36com-
mitted by thecompetent authorities causedactual prejudice to the defend-
ant in the process of administration of criminal justice.

122. The Court reaffirms,that the case before it concerns Article 36of

the Vicnna Convention and not the correctness as such of any conviction
or sentencing. The question of whether thc violations of Article 36, para-
graph 1, are to bc regarded as having, in the causal sequence of events,
ultimately led to convictions and scvere penalties is an integral part of
criminal proceedings before the courts of the United States and is lor
them to dctcrmine in the process of review and reconsideration. In so
doing, il is for the courts of the United States to examine the facts, and in
particular the prejudice and its causes, taking account of the violation of
the rights set forth in the Convention.

123. 11 isnot to be presumed, as Mexico asserts, that partial or total
annulment of conviction or sentence providcs the necessary and sole

remedy. In this regard, Mexico cites the recent Judgment of this Court
in the caseconcerning the Arrest Wurranrof II April 2000 (Drmour~rtic
R~public ofthe Congo v. Belgium), in which the "Court ordcred the
cancellation of an arrest warrant issued by a Bclgianjudiciab oKicial in
violation of thc international immunity of the Congo Minister for Foreign
Affairs". However, the present case has clearly to be distinguished from
thc Arrest Wurrant case. In that case,the question of thc legality under
international law of the act of issuing thc arrest warrant against the
Congolese Minister for Forcign Affairs by the Belgianjudicial authori-
ties was itsclfthe subject-rnatlcr of the disputc. Since the Court found
that act to be in violationof intcrnational law rclating to immunity, the
proper legal consequence was Lbrthe Court to order the cancellation of
the arrest warrant in question (1.C.J. Reports 2002, p. 33). By contrast,

in the present case itis not the convictions and senlcnces of the Mexican
nationals which are to be regarded as a violation of international law,
but solely certain breaches of treaty obligations which preceded them.

124. Mexico has further contended that the right to consular notifica-
tion and consular communication under the Vienna Convention is a fun-
damental human right that constitutes part of due process in criminal
proceedings and should be guaranteed inthe territory of each of the Con-
tracting Parties to the Vienna Convention ; according to Mexico, this6 1 AVENA AND OTHERS (JUWMEN'I')

right, as such, is so fundamentalthat its [email protected] pro-
duce the effect of vitiating theentire processf Ihc criminal proceedings
conducted in violation of this fundamental right. Whether or not the
Vienna Convention rights are human rights is not a matter that this
Court need dccide. The Court would, howevcr, observe that neither the
text nor the object and purpose ofthe Convention, nor any indicationin
the travaux prkpnraloires, support the conclusion that Mcxico draws
from its contention in that regard.
125. For these reasons, Mexico'sfourth and fifth submissionscannot
bc upheld.
126.The reasoning of the Court on the fifth submission of Mexicois
equallyvalidinrelation to the sixth submissionof Mexico.In elaboration
of its sixth submission, Mcxicocontends that,

"As an aspcct ofreslitutioin inlegrum, Mcxico is also entitled to
an order that in any subsequent criminal proceedingsagainst the
nationals, statements and confessionsobtained prior to notification
to the national of his right to consular assistance be excluded."

Mexico argues that "The cxclusionaryrule appliesin both common law
and civillawjurisdictions and requires the exclusion of evidencethat is
obtained in a manner that violatesdue proecssobligations", and on this
basis concludesthat

"Thc status of the exclusionaryrulc asa general principle of law
permits the Court to order that the United States is obligated to
apply this principlein respectof statements and confessions givento
United Stateslaw enforcementofficialsprior to thcaccused Mexican
nationals being advised or their consular rights in any subsequent
criminal proceedingsagainst thcm."

127. The Court does not consider that it is necessaryto enter into an
examination of thc merits of thecontention advanced by Mexicothat the
"exclusionary rule"is "a general principle oflawunder Article38 (1) (cJ
of the ... Statute" of the Court. The issue raisedby Mexico in itssixth
submission relatesto the qucstion of what legalconscquencesflow from
the breach of the obligations under Article36,paragraph 1 - a question
whichthe Court has already sufficientlydiscussedabovein relation to the
fourth and the firth submissonsof Mexico.The Court is of the view that
this qucstion is one whichhas to beexamined under the concretccircum-
stances ofeach caseby the United States courts concernedin the process
of their reviewand reconsideration.For this reason, the sixth submission
of Mexicocannot be upheld.

128. While the Court has rejected the fourth, fifth and sixth submis-
sions of Mexicorelating to the remediesfor the breaches by the UnitedMcxiquc, ce droit, en tan1 que tel, est si fondamental quesa violation a
ipsofacto pour cfTeldc vicierl'ensemblede la prockdure penale conduite

convention, ni aucune indication qui figurerail dans les lravaux pripara-
toires, ne permettent d'arrivek la conclusion que lc Mexique lire de cet
argument.
125. Pour ces motifs, les quatrilme et cinquieme conclusions du Me-
xique nc sauraient &Ireaccueillies.

126. Le raisonncmcnt suivi par la Cour a propos de la cinquikme

la Cour a dkji sumsarnment trait6 a propos des quatrikme et cinquieme

naux amkricains concernks par le processus de reexamen et de revision
d'examiner cette question 6 la lumibe des circonstances concrktes
propres a chaque eas. Pour ce motif, la sixiemeconclusion du Mexique
ne sauraitEtreaccueillie.
128. Si la Cour n'a pas donne suite aux qwatrikme, cinquieme et
six~emeconclusions du Mexique concernant les mesures a prendre pourSlalehof its international obligationsunder Article 36of the Vienna Con-
vention, the Factremains that such breachcs have been committed, as the
Court has found, and it isthus incumbent upon the Court to specifywhat
remediesare required in order to redress the injury done to Mexico and
to its nationals bythe Unitcd States through non-compliance with those
international obligations. As has already been observed in paragraph 120,
the Court in the LaGrandJudgment stated the gencral principle to be
applied in such cases by way of a remedy to redress an injury of this kind
(I.C.J. Reports 2001, pp. 513-514, para. 125).
129. In this regard, Mexico'sseventh submission also asks ~hcCourt

to adjudge and declare:
"That to thc extent thatany of the 52convictions or senlcncesare
nol annulled, the United States shall provide, by means of its own
choosing, meaningful and effectivereviewand reconsideration of the
convictions and sentences of thc 52 nationals, and that this obliga-

tion cannot be satisfiedby means of clemency proceedings or iFany
municipal law rule or doctrine [that fails to attach legalsignihcance
to an Article 36 (I) violation] is applied."
130. On this question of "review and reconsideralion", the United
Statcs lakes the position that it has indeed conformed its conduct to the
Lacrand Judgment. In a further elaboration of this point, the United

States argues that "[tlhe Court said in LaCrtrndthat lhe choice of means
for allowing the reviewand reconsideration il called For'must be left'to
the United States", but that "Mexico would not leave this choice to the
United States hut have the Court undertake the review instcad and
decide at once thal thebreach rcquircs the conviction and sentence to bc
set aside ineach case".
131. In stating in its Judgment in the LcrGrand case that "the United
States 01'Arncrica, by trnerms ofils own choosing, shall allow the review
and reconsideration of the conviction and sentence" (I.C..J. Reports '
2001, p. 516, para. 128 (7); emphasis added), the Court acknowledged
that the concrete modalities for such reviewand reconsideration should
be left primarily to the United States. It should be underlined, howcvcr,
that this freedom in the choice of means for such reviewand reconsidcra-

tion is not without qualification: as he passage of the Judgrncnt quoted
above rnakcs abundantly clear, such reviewand reconsideration has to be
carried out "by taking account of the violation of the rights set forth in
the Convention" (I.C.J. Rcporls ZOUJ,p. 514, para. 125);including, in
particular, the question of lhe lcgal consequences of the violation upon
the criminal procccdings that have followed the violation.
132. Thc United Statesargues (1)"that the Court'sdecisioninLclGrand
in calling for reviewand reconsideration called for a process to re-exam-
ine a conviction and sentencein light of a breach of Article 36"; (2) that,
"in calling for a processof rcview,the Court necessarily impliedthat one
legitimate result of that process might bea conclusion that the conviction

and scntcnce should stand"; and (3)"that the relief Mexico seeksin thiscase is flatly inconsistentwith thc Judgment in LaGrand: it seeks pre-
cisely the award of a substantive outcome that the Lacrand Court
declined to provide".

133. However, the Court wishesto point out that the current situation
in the United States criminal procedure, as explained by the Agent at thc
hearings, is that

"If lhc derendant allegedat trial that af;uilureof consular informa-
tionresulted in harm to u pclrtiouhr right essen~iul[(Ia fairfrial,an
appeals court can review how rhelower courl handledthat claim of
prejudice",

but that
"Ij theforeign nalional did not raise his Arlrcle36 clcriruttriul,

he mayface proceduraI constraints [i.e., the application of the pro-
cedural default rule]on raising that particular claim in direct or col-
lateral judicial appeals" (emphasis added).

As a result,adaim based on the violation of Article 36, paragraph I, of
the Vienna Convention, however meritorious in itself,could be barred in
the courts of the United States by the operation or the procedural default

rule (see paragraph 111 above).
134. It isnot sufficientfor the United States to argue that "[wlhatever
label [the Mexicandefendant] places on his claim, his right ... must and
will he vindicated if il is raisedin someform at trial" (emphasis added),
and that

"Inthat way, even though a failure to label the cornpIaint as a
breach of the Vienna Convention may mean that he has lechnically
speaking forfeited his right to raise this issue as a Vienna Conven-

tion claim,on appeal that failure would not bar him from independ-
ently assertinga claim tl?ahe wasprejudiced becuusr he lucked his
critical protection neededfor u fair trial." (Emphasis added.)

The crucial point in this situation is that, by the operation of the
procedural default rule as it isapplied at present, the defendant is

cffcclively barred from raising the issue of the violation of his rights
under Article 36 of the Vienna Convention and is limited to seeking the
vindication of his rights under thc Unilcd States Constitution.

135. Mexico, in the latter part of its seventh submission, has stated
that "this obligation [of providing review and reconsideration] cannot bcculpabilitk et de la peine)},et 3) que {(leremede dernandi: par le Mexique

135. Dans la seconde partie de sa septikmeconclusion, le Mexique dit
que crcetteobligation [consistant a assurer le rCexamenet la revision] nesatisfied by means of clemency proceedings". Mexico elaborates this
point by arguing first orall Ihat "the United States's reliancon clemency
proceedings is wholly inconsistent with its obligation to provide a
rcmedy,as that obligation was found by this Court in LaCratnf'. More
specifically, Mexico contends :

"Firs t s clear that the Court's direction toIhc United Statcs in
LuGrund clearly conteinplated that 'review and reconsideration'
would be carried out by judicial procedures . . . .

Secmrsrlt,heCourt was fully aware that the LaGrand brothers had
received a clemency hearing, during which the Arizona Pardons

Board took into account the violation of their consular righls.
Accordingly, the Court determined in LuGrundthat clcmcncy review
alonc did not conslitutc thcrcquired 'reviewand reconsideration' . . .

Finully,the Court specified that the United States must 'allow the
review and reconsideration of the conviction lrnd sentence by taking
account of the violation of the rights set forth in the Convcnlion'. ..
it is a basic matter of U.S. criminal procedural law that courts
rcvicw convictions; clemency panels do not. With the rare exception
of pardons based on actual innocence, the focus of capital clemency
review is on the propriety of the sentence and not on he underlying
conviction."

Furthermore, Mexico argues that the clemcncy process is in itself an
ineffective remedy to satisfy the international obligations of thc Unitcd
States. It concludes: "clemency review is standardless, secretive, and
immune from judicial oversight".

Finally, in support of its contention, Mexico argues that
"the failureof state clemency authorities to pay heed to the interven-
tion of the US Department of State in cases of death-sentenced
Mexican nationals refutes the [United States] contention that clem-
ency review willprovide meaningful consideration of the violations

of---ghts conferred under Article 36".

136. Against this contention of Mexico, the United Statcs claims that
it "gives 'full effect'to the 'purposes for which the rights accorded under
[Article 36, paragraph l,] arc intended' through executive clemency". It

argucs that "[tlhe clemency process . . is well suitedto the task or pro-
viding review and reconsideration". The United States explains that
"Clemency . . . more than a matter of grace; it is part or the overall
scheme for ensuring justice and fairness in the legal process" and thatpourra etre satisfaite par des prockdurcs de grricen.Le Mexique dive-
loppe cet argument en soutenant avant tout que ccs'cnrcrncltrc aux pro-
ckdures de recours en grice ne saurait pcrmctlre aux Etats-Unis de

lations' ofthe United States through which errors are addressed".

137. Specificallyin Ihc context of the present case, the United States
contends that the followingtwo points are particularly noteworthy:

"First, these clemencyprocedures allowfor broad participation by
advocates of clemency,including an inmate'sattorney and the send-
ing state's consular officer.. Second, these clemency officialsare
not bound by principles of procedural default, finality, p~ejudice
standards, or any other limitations on judicial review.They may
consider any facts and circumstances that they deem appropriate
and relevant, including specifically ViennaConvention claims."

138. The Court would emphasize that the "review and reconsidera-
tion" prescribed by it in the LaGraiadcase should be effective.Thus it
should "tak[e]account ol'thcviolation of the rights set forth in [Ihc]Con-
vention" (I.C.J. Reporrs 2001, p. 516, para. 128 (7))and guarantee that
the violation and the possible prejudice caused by that violation will be
fully examined and taken into account in the reviewand reconsideration
process. Lastly, review and reconsideration should be both of the sen-
tence and of Ihe conviction.

139. Accordingly, in a situation of the violation of rights under
Article 36, paragraph I, of the Vienna Convention, the defendant raises
his claim in this respcct not as a caof "harm to a particular right essen-
tialto a fair trial- a concept relevant to the enjoyment of due process
rights under the United States Conslitution - but as a case involving the
infringement ofhis rightsunder Article 36, paragraph 1.The rights guar-
anteed undcr the Vienna Convention are treaty rights which the United
States has undcrtaken to comply with in relation to the individual con-
cerned, irrespectiveOF the due process rights under United States consti-
tutional law. In this rcgard, the Court would point out that what is
crucial in the reviewand reconsideration processis the existenceof a pro-
cedure which guaranlccs that full weight is given to thc violation of the
rights set forth in the Vienna Convention, whatever may be the actual
outcome of such review and reconsideration.

140. As has been explained in paragraphs 128 to 134above, the Court

isof the viewthat, in cases where the breach of the individual rights of
Mexican nationals undcr Article 36, paragraph 1 (h), of the Convention
has rcsultcd, in the sequenceof judicial proccedings that has followed, in
the individuals concerned being subjected to prolonged detention or con-
victed and sentenced to severe penalties, the legal consequences of this
breach have to be examined and taken into account in the course of- --

57review and reconsideration. The .Court considers that it is thejudicial
process that is suiled to this task.

141. The Court in the LaCrcrnA case Ieft to the United States the
choice of mcans as to how reviewand reconsiderationshould beachieved,
especially in Ihe light of the procedural defaull rule. Nevertheless, the
prcmisc on which the Court proceeded in that case was that the process

of review and reconsideration should occur within the overall judicial
proceedings relating to the individual defendant concerned,
142. As regards the clemencyprocedure, thc Court notes that this per-
forms an important function in thc administration of criminal justice in
the United States and is "thc historic remedy for preventing miscarriages
ofjustice whcrcjudicial process has been exhausled" (I-lerrerv. Collins,
506US 390 (1443) at pp. 41 1-412). The Court accepts that executive
cIcmency,while not judicial, is an integral part of the overall scheme for
ensuringjustice and fairness in thc legal process withinthe United Slales
criminaljustice system. It must, however, point out that what is at issue
in the present caseis not whcther executive clemencyas an institution it;
or is not an integral part of the "existing laws and regulations of the

United States", but whether the clemencyprocess as practised within the
crirnina!justice systemsof different stalesinthe United States can, in and
of itself, qualify as an appropriate means for undertaking the effective
"review and reconsideration of the conviction and sentence by taking
account of the violation of the rights set Sorlinthe Convention", as the
Court prescribed in the LaGrrrndJudgment (I.C.J. Rr.porl.52001, p.514,
para. 125).

143. It may be true, as the United Stalcs argues, that in a number of
cases "clemency in fact results in pardons of convictions as well as com-
mutations of senlences". In that sense and to that extent, it might be
argued that the facts demonstrated by the United Stalcs testify to a
degree of effectivenessof thc clemencyprocedures as a means of relieving

defendants on death row rrom cxccution. The Court notes, howcvcr, that
the clemency process, as currently practised within the Unitcd States
criminal justice system, does not appear to meet the requirerncnts
described in paragraph 138 above and that it is therefore not sufficientin
itsclf'to serveas an appropriate means of "reviewand reconsideration" as
envisaged bythe Court in the LaGrandcase. The Court considers never-
theless that appropriate clemency procedures call supplement judicial
review and reconsideration, in particular where the judicial systemhas
failed to take duc account of the violation of thc rights set forth in the
Vienna Convention, as has occurred in the case of the three Mcxtcan
nationals referred to in paragraph 114 above. 144. Finally, the Court willconsider the cighth submission of Mexico,
in whichit asks the Court to adjudge and declare:
"That the [United States] shall ceaseils violations of Article 36 of

the ViennaConvention with regard to Mexico and its 52 nationals
and shall provide appropriate guarantees and assuranecs that it
shalltake measures sufficientto achieve increased compliance with
Article36 (I) and to ensure compliancewith Article 36 (21.'"

145. In this respect,Mexicorecognizesthe effortsby the United Stares
to raise awarenessof consular assistance rights,through the distribution
of pamphlets and pocket cards and by the conduct of'training pro-

grammes, and that the measures adopted by the United Slates to that
end were noted by the Court in its decision in the LuGrundcase (I. C.J.
Reports 2001, pp. 511-51 3,paras. 121, 123-1241,Mcxico,however,nolcs
with regret that
"the United States programme, whatever its components, has
proven ineffective to prevent the regular and continuing violation
by itscompetent authorities of consular notification and assistance
rights guaranteed by Article 36".

146. In particular, Mexico claims in relation to thc violation of thc
obligations under Article 36, paragraph I, of the Vienna Convention:

"First,competent authoritiesof the United States regularly failto
provide the timely notification required by Article 36 (1) (h) and
thereby lo [sic] frustrate the cornrnun~cationand access conlem-
plated by Article 36 (1) (u)and the assistance contemplated by
Article 36 (1) (u) .These violalions continue nolwithstanding the
Court's judgment in LaCrundand the programme described there.

Mexico has dernonstratcd, moreover, that the pattern or regular
non-compliance continues.During the firsthalf of 2003,Mexicohas
identified at least one hundrcd cases in which Mexicannationals
havebeen arrested by competent authoritiesof the United Statesfor
serious feloniesbut not timely notifiedof their consular notification
rights."

Furthermore, in relation to the violation of the obligations under
Article 36, paragraph 2, of the Vienna Convention, Mexico claims:

"Second,courts in the United States continue to apply doctrines

of procedural default and non-retroactivity that prevent thosccourts
from rcaching the merits of Vienna Convention claims, and those
courts that have addressed the merits of those claims (becauseno
procedural bar applies)have repeatedlyheIdthat no remedyis avait- 144.En dernier lieu, la Cour examinera la huitikme conclusion du
Mexique dans laquelle cedernier la prie de direl juger que:
r{Les Etats-Unis d'Arnerique devront cesser leurs violations de

cinquantc-deux ressortissants et devront Cournir des garanties et
assurances approprikes qu'ilsprendront des mcsures suffisantespour

faire plus largcment respecter le paragraphe 1 dc I'article36 et assu-
rer le respect du paragraphe 2.>>
145.A cct kgard, le Mexique reconnait quc les Etats-Unis rnenent une
action pour hire rnieuxprendrc consciencedu droit l'assistanccconsu-
hire en assurant la diffusion de brochures et de fichcs et en organisant
des programmes de formation; la Cour a quant elle pris acte des me-
sures adoptkcs par les Etals-Unis a cette tin dans la decision qu'elle a
rendue dans I'afiaireLaCrand (C .J. Rccueil2001, p. 511-513, par. 12 1,

I 123-124). Le Mexique constate toutefois avec regret quc
ctleprogramme arnkricain, quelle qu'en soit la nature, [s'est]revkle
incfficace pour empicher les autoritks compktentcs de violer de
maniire rkcurrentc et continue les droits de notification et d'assis-
tance consulaires garantis par I'article36n.

146. En particulier, au sujet de la violation dcs obligations dkoulant
du paragraphe 1 de I'article36 de la convention de Vienne, le Mexique
formulc les griefs suivants:
crTout d'abnrd les autoritts compktentes dcs Etats-Unis omcttent

syslkmatiquement d'inforrner sans retard les intkcsses, ainsi que le
requiert I'alinCab) du paragraphe 1de I'article36, faisant ainsi ob-

graphe. Ces violations continuent nonobstant I'arrEt rcndu par la
Cour en l'affaire LuGrand et le programme decrit alors.
.............................
Le Mexique a en outrc dkrnontre que cette pratique de violation
systematique continue. Au cours du prcmier semestre de I'annee
2003, Ic Mexique a rccensi:au moins cent cas oi les autoritks com-
petentes des Etats-Unis ont arrCti:des ressortissants mexicains prC-
sum& criminels sans les informcr en temps voulu de leurs droits en
matiere de notification consulaire.)>

En outre, en ce qui concerne la violation des obligations decoulant du
paragraphe 2 de l'article 36 de la convention de Vienne, le Mexique for-
muje les griefsci-apres:
crEnsudtul,es juridictions des Etats-Unis continuent d'appliquer
Icsdoctrines de la carence procedurale et de la non-rktroactivile qui

les empgchent d'examiner au fond les rklamations presentkes au
titre de la convention de Vienne; quant aux juridiclions qui ont
examine de telles demandes au fond (parce qu'aucune resuiction able for a breach of the obligations of Article 36 . .. Likewise, the
United States' reliance on clemency procccdings to meel LaGrirnds
requirement of review and reconsideration represents a deliberate
decision to allow these lcgal rules and doctrines to continue to have
theirincvitable effect. Hcnce, the Unitcd States continues to breach
Article 36 (2) by failing to give full effect to the purposes for which
thc rights accorded under Article 36 are intended."

147. The Unilcd States contradicts this contention of Mexicoby claim-
ing that "its en'ortsto improve the conveyanceof information about con-
sular notification are continuing unabated and are achieving tangible
results".Ttcontends that Mexico "Failsto establish a 'regular and con-
tinuing' pattern of breaches ofArticle 36 in the wake of LuGrand'.

148. Mexico emphasizesthe necessity of requiring the cessation ofthe
wrongful acts because, italleges,the violation of Article36 with regard to
Mexico and its 52 nationals still continucs, The Court considers, how-
ever, that Mexico has not establisheda continuing violation ofArlicle 36

of the YiunnaConvention with respcct to the 52 individuals rekrred toin
its final submissions; it cannot therefore uphold Mexico's claim seeking
cessation. TheCourt would moreover point out that, iwasmuch as these
52 individual cases are at various stages of criminal proceedings before
the United Statcs courts, they are i11the slate of pcndente lire; and thc
Cvurt has already indicated in respect of them what it regards as the
appropriate remedy, namely review and reconsideration by reference to
the breach of the Vienna Convention.

149. The Mexican request for guarantees of non-regctilion isbased on
its contention that beyond these 52 cases there is a "regular and continu-
ing" pattern of breaches by the United States of Article 36. In this
respect, the Court observes that thero:is no evidcnce properly before it
that would establish a gcneral pattern. While it is a matter of concern

thal, even in the wake of theLaCrcrndJudgment, there remain a substan-
tialnumbcr of casesof f'ailureto carry out the obligation to f~~rnishcon-
sular information to Mexican nationals, the Court notes that the United
States has been making considerable efforts to ensure that itslaw enforce-
ment authorities provide consular information to every arrcsted person
they know or havc reason to bclieve is a foreign national. Especially at
the stage of pre-trial consular information, it is noteworthy that the
United States has been making good faith efforts to implement the obli-
gations incumbent upon it undcr Article 36, paragraph 1,of the Vienna
Convention, through such measures as a new outreach programme
launched in 1998,including the dissemination to fcdcral, state and local
authorities of the State Department booklet mentioned ahovc in para- prockdurale n'y Ffaisaitobstacle), cllcs ont invariablemcnt decla-

148. Le Mexique insiste sur la niccssite de demander la cessation de
I'illicitc parce que, psitend-il, la violalion de I'article 36 a l'kgard
du Mexique et de ses cinquante-deux rcssortissants persiste. La Cour
considere c~pendant que le Mexique n'a pas Ctabli l'existcnce d'une
violation coiltinue de I'article36 de la convention deVienne i I'egarddes
cinquante-deux pcrsonnes visCes dans ses conclusic~nsfinales ; elie ne
saurait des lor: accueillir la demande mexicaine visant a obtenir la
cessation. Elle fera ctl outre observcr que, comme ws ctnquante-deux
cas individuels se trouvent actuellement itdilrerents stades de la prock-
dure pinale devanl les juridictions amkricaines, ils sent pendants; et la

Cour a deja indiqd, en ce qui les conccme, ce qu'elleconsidkre cornme

149. La demande de garantie de non-repetition Sormulkepar le Me-
xiquc sc base sur I'alltgation que, au-dcla des cinquante-deux cas consi-
dCrb, il existerait unc pratique de violation ccrkcurrentcelcontinue,, dc
I'article36 par les Etats-Unis. A cet egard, la Cour fait observer qu'cllc
n'a pas ete dhrnent saisie dlklCmentsde preuvc de nature ri fairc appa-
raitre unc pratique habituelle revktant un caractgre genkral. S'il y a des
raisons de sYinquiCtedru fail que, mime h la suite du prononcc de 1'arrCt
en l'affaircLuCrund,il subsisteun grand nombre de cas oh I'obligationde
fournir I'information consrllaire a des ressortissants mexicains n'est pas
rcspecde, la Cour prend acte de ce que les Etals-Unis ont men6 une
action intcnsive pour f-aircen sorte que lcs servicesde la force publique
fournissent l'information consulairerequise rilout individu arrCiCdont ils
savenl ou ont tout licude croire qu'il s'agit d'un ktranger. Tout particu-

likrement en cc qui coticernc l'information consulaire iicornmuniquer
prkalablement au proces, il convient de relever que les Etats-Unis ont
cherchi de bonne foi ris'acquitter dcs obligations lcur incombant en
vertu du paragraphe 1de I'ariicle36 de laconvcntion de Vienneen adop-graph 63. The Court wishes to recall in this context what it has said in
paragraph 84 about efforts in somejurisdictions to provide the informa-
tion under Article 36,paragraph l (bJ, in parallel with thc reading of the
"Miranda rights".

150. The Court would further note in this regard that in the LaGrand
case Germany sought, interalia, "a straightforward assurance that the
United States will not repeat its unlawfuI acts" (I.C.J. Rtports 2001,
p. 511, para. 120).With regard to this gcneral demand for an assurance
of non-repetition, the Court stated:

"lf a State, in proceedings before this Court, repeatedly refersto
substantial activities whicitiscarrying out in order to achievecom-
pliance with certain obligations under a treaty, then this expresses a
commitment to follow through with the efforts in this regard. Thc
programme in question ce~tainlycannot provide an assurance that
there willnever againbe a failure by the United Slates to observe the
obligations of notification undcr Article 36 ol'the Vienna Conven-
tion. But no State could give such a guarantee and Gcrmany does
not seek it. The Court considers that the commitment expressed by
the United States to ensure implementation of the specificmeasures
adopted in performance of its obligations under Articlc 36, para-
graph 1 (b),must be regarded as meeting Germany's request for a
general assurance of non-repetition." (IC.J. Reports 2001, pp. 512-

513, pard. 124.)

The Court believes that as Car as the request of Mexico for guarantees
and assurances of non-repetition isconcerned, what the Court stated in
this passage ofthc LaGrandJudgment remains applicable, and therefore
meets that request.

151. The Court would now re-emphasize a point of importance. In the
present case,it has had occasion toexamine theobligations of the United
States under Article 36of the ViennaConvention in relation to Mexican
nationals sentenced to death in the United States. Its findings as to the
duty of review and reconsideration of convictions and sentences have
been directed to the circurnstancc of severe penalties being imposed on
foreign nationals who happen lo be of Mexican nationality. To avoid any
ambiguity, it should bemade clear that, whilewhat the Court has stated
concerns the Mexican nationals whose cases have bcen broughl bcfore it

by Mcxico, the Court has been addressing the issuesof principle raisedintant certaines mesures, qui ont consisti par exempleA lancer en 1998un
nouveau programme de sensibilisation, lequel s'est traduit notamment
par la diffusion aupris des autorites Ekdkrales,etatiqucs et locales, du

Cour souhaite riidrer dans ce contexte les observations qu'ellea formu-

afin de fournjr, parallclementiila lecture des c<droitsMirunda,), I'infor-
mation prkvue h I'alinta h) du paragraphe I de I'article 36.
150. La Cour entend par ailleurs rappeler;ice sujet que, dans l'affaire
Lacrand, 1'Allemagnea notamment voulu obtenir crdesEtats-Unis une
assurance pure et simple qu'ils ne rkpctcront pas leurs actcs illicites,,
(C.I.J. Recueil 2001, p. 511, par. 120). Conccrnant cette demande de
caractkre genkral visant l'obtention d'une assurance denon-ripetition, la
Cour a dit ceci:

nikrc repetCedevant la Cour aux activites substantielles auxquelles
il se livre aux fins de mettre en muvre certaines obligations decou-

obligations autitre de I'alinta h) du paragraphe 1de l'article36 doit

La Cour estime que, s'agissantde la dcmande du Mexique visant a abte-
nir des garanties et assurances de non-rkpttition, ce qu'elle a dit dans
I'extraici-dessus dc 1'arrEtLuCrand dcmeure applicable ct satisfait ladite
demande.

151. La Cour souhaite cncore rkaffirmer un point important. En

Etats-Unis en vertu de I'article36de la convention de Vienne a 1'Cgardde

nalitk mexicaine. Pour tviter toute ambiguitk, il y a lide prkciser que,
bien que les observationsde la Cour intkrcssent lescasdesressortissants
mexicains qui lui ont etk sournis par le Mexique, elle s'est r~l'krkea:ux70 AVENA AND UTHERS (~UDGMENT)

the course of the present proceedings from thc viewpoint or the general
applicalion of the Vienna Convention, and there can bc no question of
making an a corz!rurioargument in respect of any of the Court's findings

in the present Judgment. In other words, the fact that in this case the
Court's ruling has concerned only Mexicannationals cannot be taken to
imply,that the conclusions reached by it in the present Judgment do not
apply to other foreignnationals finding themselvesin similar situations in
the United Slates.

152. By its Order OF5February 2003the Court, acting on a request by
Mexico, indicated by way ofprovisional measure that

"The United States of America shall take a41measures neccssary
to ensurethat Mr. CksarRoberto Fierro Rcyna, Mr. Roberto Moreno
Ramos and Mr. Osvaldo Torres Aguilcra are not exccuted pending
finaljudgment in these proceedings" (I.C.J.Reports 2003, pp. 91-92,
para. 59 (1))(see paragraph 21 above).

The Order of 5February 2003,according to its terms and to Article 4 1or
the Statute,was effectivepending finaljudgment, and the obligations of
the United States in that respect are, with effect from the date of the
present Judgment, replaced by those declared in this Judgment. The
Court has rcjccted Mexico'ssubmission thal, by way of re.stirutiininrp-
gruwa, the United States is obliged to annul the convictio~snd sentences
of all of the Mexican nationals the subject of its claims (see above, para-
graphs 115-125).The Court has found that, in relationtothesc three per-
sons (among ~thcrs), the United States has committed breaches of its
obligations under Article 36,paragraph 1 (b), of the Vienna Convention
and Arlicle 36,paragraphs I (a) and (c), of that Convention; moreover,

in respect of those three persons alone, the United States has also
committed breaches of Article 36, paragraph 2, of thesaid Convention.
The review and reconsideration ofconviction and sentencc required by
Article 36, paragraph 2, which is the appropriate remedy tbr breaches of
Article 36, paragraph 1, has not been carried out. Thc Court considcrs
that in these three Casesit is for the United Statcs to find an appropriate
remedy having the nature of reviewand reconsideration according to the
critcria indicated in paragraphs 138ei seq. of the present Judgment.

153. For these reasons,
