1.O1 This Reply issubmittedin confumity with the Court's Orderof20
December1994andrespondsto the Counter-Mernorioal Hungaryof 5December1994. Itis
appropriateto begin this Reply byinformingthe Court of two developments thathave
importanceforthiscase.
I.O2 Thefirstisthaton 17Match 1995,Hungary demolishedthemEer dam,
thatisthetemporaryp, rotectingwallsurroundinheconstructionsitatNagymaros.Thesite
isnowinundated bythe watersoftheDanube.
r.03 The second is thaton 19 ApriI1995, thetwo Partiesconcluded an
Agreement concerningcertaintemporarytechnicaimeasureand dischargesintheDanube and
Mosoni branchofthe ~anube'. Under this Agreement,Slovakiawill increasetdischargt
intothe Mosoni branchof theDanube to43 m3/s(subjectto the hydrologicaandtechnical
conditions iAnnex I tu thAgreement). And the dischargintuthe main riverhedwill be
increasedtoan annualaverageof400 rn3isinaccordancewith mlesfinAnnex 2thereto).
1.04 Further,Hungarywill construct an underwaterweir at rkrn 1843
l
(cunstmction tu be completedi50 days). Monitoringof the effects of these improvements
wiilbe subjectujoint assessment,andanydisputesoverperformancewillbe resolvedthrough
thegoodofficesof theexpertsofthe CommissionoftheEuropean Union.

I
ta date, Hungary has attempted to transform the case into a debate over ecological or
l
environmentailssues,and to obscure therealissues,whicharethoseput to the Coun in the
SpecialAgreement.
I
1.O7 The essentialissuesinthis case'aIdtpend upon the 1477 Treaty,freeiy
1
concluded betweenHungaryandCrechoslovakia.Thisis ieflectedinArticle2 of the Special
Agreement, whichgivesprimacy to theTreat nrequiring IheCOUR todecide "onthebasisof
I
theTreatyand niles andprincipleof generalinternationlaw ...".And on that basisthe core
I
issues requiringdecisionare: (i) whether Hungarywas enIitleto suspendand subsequently
abandon theworiq and (ii) whether, in the faceof ~un~kry*s conducg Czechoslovakia was
entitledto proceedwiththe "provisionas lolution"(VariAt "C"). Al1the other issues are
I
subordinateto,or consequentialupon, thosetwo coreissues. Hungarc yannot,and doesnot,
evade the factthat itcondüct was primafacie inbreach of the 1977 Treaty. Asthe SpeciaI

becomes entirelyperipheran Hungary's pleadings- whether because itwas terminat byd

Treaty partiesin 1977 did riot assume they had identifieciand solved each and eveq

SEC~ION~. Brief Analvsis of the "~cientificCase" Now Presented in the
Hun~arianCounter-Memoriaf
1.2 One of the striking features of the original HungarianMernorial was
that, although the Hungariacaserested essentialon a!pleaof "ecoiogicalnecessity", the
scienùfc evidenîe forsuch a plea wu not presented id that Mernorial. Part of that
Mernorialgave only a "provisional"'ccountof theriskrandadmittedthe task of proving
thom riskto be "adiEcult task,withmany uncertaintied"'Belatedly,Hungary'sCounter-
Memorialnow attempts to providethe evidenceor proofwhich, properlyspeaking,should
havebeencontained in the Decfaratioof 16 May 1992 andin its Mernorial.Infact,No-

I.25 Hiingaryessentiallyarguesthat the legal requirement ofan EIA was
mandatoryin 1989, with the result thainthe absence of anEIA eitherTreaty Party could

foremost, itmarks a shiftinHungary's formerargumentcontainedinits 1992 Declaration and

Because this hasbeenshowri to be manifestlyuntrue, Hungarynow seeks tu show that no

suspensionof works in 1989, which is now categorisedas a refusa1 toproceed"without a

1.32 It is obviousrhat this new"ScientifiEvduation" of 1994couId not

1.33 The scientificbasisfor Hungary'sdecisionswould have to rest on

59 -eeS,lovakCounter-Mernoral,r10.36,gtçes. A. Article 4: The Issueof a TemporarvWater Management Repime
1-39 As willberecalled,Article4 providesas follows:
"f 1)the Partiesagreethat, pertdithe finaiJudpent of theCourt, they will
estabiish and impIement a temporary water management regimc for the
Danube ".
And, of course,thisparagrap h oesnotstandalone. Paragraph 2 makes itclearthat, pending
the estabIishmenofa ?WMR, ifeitherPart)believes"itrightsare endangered" recoursemay
behadtoconsuItation, tothe expertisof the EuropeanCornmunity,but to theCourt.
1.40 This position makes eminentlygood sense. The elaboration and
implementation of a TWMR is ahighlytechnicalproblem and in no sensea legal problem
appropriatefor reference toacourt of law. It was for preciselythireason thatthi wsas a
matter tube resoIvedby the Parties,with the assistanofthe technicalexpertsappointedby
the EC. Indeed,it was inherentlyunIikeIythat the Parties would have sought tu involvethe
International ourtina technicaprobkrnofthis kind.
1.41 Fromthis itfollows -and,as willbe seen,theterms of Article2 confirm
this-that it wasnevercontemplatedby the Partiesthat theCourt would be corifruntedby an
aIIegatiuof"breach" ofArticle4. Beingin the natureofa pacturnde wntrahendoa, it wauld
be dficuIt inanyevent to seehow faiIureto agreea TWMR couIdbe a "breach"attributable
toone Party.
1.42 Itistheviewof Slovakiathat the Agreement of 19 April1995 is,infact,
an agreement on a TWMR because iternbodiesal1those elementswhich the Partieshavehad

werethe issues discussedinthe context ofa TWMRunder Article4, andthese are precisely
the issuessertIedby the Agreementof 19 April1995. Moreover the role of the expertsfrom

1.45 Then thereis a furtherissuerelating tu Article 2This &seshm
Hungary's attempttouse whatHungaryregardsaslegalprinciples relatintotheprotectionof
the environmentto overturn theexpressprovisionsof the 1977 Treaty. Hungary seeksto
justify this attemptthebasisofthe referencetu "principlofgeneral internationailawin
Article2(1)of the SpeciaAgreement. But theargumentis tutdrymisconceived. The phrase
used in Articl2(I)is: "TheCourt isreqütstedtu decideonthe bais oftheTreaty and niles
andprinciplesof generalinternationalla...." Thusthe SpecialAgreementenvisagedthat
suchniles andprinciplecouldbe usedto assisin theinterpretatiof the 1977 Treatyandto
supplementthe Treaty provisions,wherenecessary,and nottuovede them asa kind of&

and principles,siftheywere jusCO- isinconceivable.The rnatteisfurtherelaboratein

1.46 In the finalanalysis,however,it becornesclear that Hungaryinvitesthe

inreaiityinvitesthCourtto makea politicaljudgmentaboutwhether thePartieswererightto

1.47 Thus, the Court is to be distractedfrom the strictrequirements

2.02 Following faithfulthe approachused extensivelyin its Mernoriai,
Hungaryinvokesin supportof its lineof argumentw, ithoutany attemptat differentiatia,
broad mixtureof rulesandlegalprinciplesofdiversetype,originand date. In itselsuch a
wayof proceedingmaynot necessarilybe incorrectandit iscertainlyarguabthat:
"According toArticle2 of the SpecialAgreement,the Court isrequesied tu

MernorialexpIains this purposeimmediatdy fier it rnakesthe distinction. Iis tu asserthe
superiorstatusof thebasicTreaty of 1977to that of the 1977Mutuai Assistance Agreement
and theProtocolsamending it:
"Itisclearthattheseagreements couldnotmodifytheTreaty itseltheyhad to
be - and were - instrumentsto furtherits implementitionin pursuance of its
purposes9 '.
From this,Hungary goes sufar asto drawthe concIusionthat these "secondary instruments"
couIdbesuspended byone partyif theywere not adequateto "ensurethe fiIIIimplementation
of theprincipaltreaty". Theseargumentsencorinter anumberufubstacles.
2.08 In the first place, the principlon which Hungaryrelies is entirely
invented. An agreementthat enters into force simplyupon signature(accord en forme
simplifiée )s for examplethe 1977 MutualAssistanceAgreement, does not havea stahis
inferiorto aforma1 treaty(en formesolennelle)suchas the 1977 Treaty(enteredintoon the
same day').Accrirdingto Article11 of the ViennaConvention on the Law of Treaties,the
consentof a Statetu be boundby atreaty maybeexpressedeitherby signature,by ratification
or by anyother meanaif so agreed;and the meansof expressingagreementhas noIegaI effect
on the meaningand IegaIvalidity ofthe treatyor agreementH . Besides,in the presentcase,
ArticIes2 and 3 of the1977 Mutual AssistanceAgreementmodifythe principleofthe equd
divisionof worksand of hydroelectripower generatedunder the Project (provided for in
Article9 of the 1977 Treaty itself). InfactWungary expresslyrecogniçes thisfact in its

Princides ofGenera1InternationalLaw
2.29 Hungary attempts to justifj its "pick and choose" approach by
ernphasisinthatArticle2 (1)of the SpecialAgreement callsonthe Court "todecide onthe
basisofthe 1977Treaty and nilesandprincipleofgeneralinternationalla^"^^.
2.30 This 1st expressionfollows a commun furnula freqrientlyused in
agreementsbywhich Statesreferdisput testhird-partsettlemerrt. et Hungaryurgesthatit
be interpreted in a nuvel way. WhaHungaq seemstu be arguin isthat byincludingthis
phase inArticle2, thePartieswere askingthe Court toappIy anv principleand rulesof
generalinternationaaw, withoutregard totheTreaty, ortu whether amle would beappIied
retroactively,or tother principlesand niles ofequalrank,such as thatof specialis.
Hungary citesnoauthorityforsuch asweepingandunprecedented interpretatioand forgood
reason:suchan interpretationis incompatiblewith the Parties'requestthat the Courtalso
decideon the basisof "theTreaty".Hungary'sinterpretati-nputforwardforthe firstimein
itsCounter-Mernoria1-appearstu be that, whethor not theTreaty iinforce for theParties,
theCourt mayignoreif infavourof suchgeneralprinciples and nile ssHungarywouldhave
theCourt appIy.ThisthePartiesmanifesflycouIdnot haveintended.
2.31 As is well knuwn,the "generalruIeofinterpretationof treatieisset
forthin Article31 of the ViennaConvention,whichprovides in partthat a treatyis to be
interpreted"inaccordancewiththeordinary meaning to begivento the termsof thetreatyin
theircontextandinthelightof itsobjectandpurpose".Indetermining the"ordinarm y eaning"

Otherwise,the Partiesmust be regarded ashaving avenI the Court unbridIeddiscretiontu

2.32 But this is not to say that the "rulesand principlesof general

2.33 Inthisregard,Hungary makes a cdcature of Slovakia'spositionwhich
it allegis:
1
'>...thatihe generalinternationallawr-lother thhnpactasunt servanda- are

The general rulesofinternationallaw arerelevantfor ad leaîttwo reasons:(i) theSpecial

2-34 But it doesnot foIIowfrom thisthat thePartiecaninvoke,andthat the
Court is tu applyno matter what principIesor ruleof internationallaw, irrespectiveof the
particularsituatioand without anjrconsiderationof their rneauir,ature,the dateof their
I
entry into force, and without takinginto account whether they are afgeneralor specific
character. Inthe present case,it isnecessary to take special account ofthe niles of
internationallaw applyingto the relationshipbetwcen custornary niles and treaties,with
l
particulareferenceto the 1977Treaty. Inthisway,the principlesof generalinternationallaw
can assisinthe interpretatioandidentificatiooftherneakng of theprovisions ofthe Treaty
(dealt withbelow in sub-sectionA) so long as they do kt modify theTreaty, as Hungary
contends theycan do (sub-sectionBbelow).

- A. The Princiriles of General International Law Do Not Justifv the
Disa~~earanceor Modification ofthe Ohiect orPurposeof the 1977
Treatv, Nor itsTermination
2.35 According to Hungq:
"Throughou itsMernorialS, lovakifocuses,to thevirtuaexcIusionofal1other
arguments ,n thelaw of treatie.... Withinthe law oftreatiesitfocuses,to
thesubstantialexclusionofother eIementsof thattaw,on the nom pactasunt
servanda6 "
And it addsthat Sluvakiarnakesthe mistakeof presenting this nom "notas a rule butas a
'r~~irne" But.thereisnoreason forHungary tobe indignant;the 1977 Treaty isinfactat
the centreofthepresent case,andhence,as SIovakiawiIIshow more specificaIin Chapters
IV and Vi below,thelawoftreatiesformstheessentialbasisof thecurrentdispute,whetherin

"Pactarunt servanda -the rulethattrsaUesare binpg on thepartiesandmust
be perfomed in goodfaith - is the fundamentalprincipleof the Iaw of
treaties."
Ami theSpecialRapporteurS , irHLimphreyWddock, emphasised its"suyrerniemportancei".
2.37 The firstconsequence of this"univkrsallryecognised"prln~iple(as the
secondclause of the Preambleto the 1969 Viema Conventionrecalls) is that,irom the
momentof enteringinto force,the 1977Treat becarne théIawfor theparties,wen as totheir
relationsintese underagreementsand rulesthen binding!m them,whether of a conventional
or custûrnarycharacter6.'
2.38 In order to arriveat this conclusiod,there ino need ttopostulate the
intrinsic superiorityoa treatyover customary rules,a thesis that Hungary would seem
l wrongIy to attnbuteto ~~uvakip. It is suffrcientmerelyto applythe two generalpinciples
pursuantto which thehierarchy of noms of internationa aw is organised:lex posteriorwriori

the greatescautionas seen,forexample, intherejectionduringthe 1969 ViennaConference
ofthedraR Articl38 submittedbythe ILC,which read asfollows:
"Atreaty maybe modified By subsequentpracticeinthe application ofthe
treatesîablishintheagreement ofthe partieIOmodifyits ."
2.41 Inany event,forsuch aresutttuoccur, anumberofconditionsmust di
be met:
-
The customarynom rnusthave the same object as the conventionai

-
Ttmust havethe same ora greaterdegreeof specificitothedse it dl

- The Partiesbytheir conduct must have demonstrated that they have

2.42 These conditions area Iong way from having beensatisfied in the
presentcase. Inessence,the new generalprinciplesinvokedby Hungaryare drawnfium the

2.43 Mthough concern fur theprotection oftheenvironmentwas not absent

It is indeed sttikithatthe sectionoftheHungarian~edoriai devoted tothe examinationof
I
"The Object andPurposeofthe ~reaty"~~fails tu mentionthe question of the protectionofthe

2.44 Obviouslyt,he conclusioncannot bedrawnfiom thisthattheprotection

HUNGARYFOR ITS SUSPENSIONAND ABANDONMENTOF
WORKS AND PURPORTEDTERMINATiON OFTHE mATY
SECTION 1. Introduction
-5.01 Hungary considers that it is relievedof the obligationto rebut
SLovakiaisdiscussion ofHungarykviolations ofthe 1977Treaty set out in the SIovak
Mernorial. Its pretextis that Slovakiahas exarninedseparatelyHungary's internationally
unlawfulactions,on the onehand,and Hungayis atfempfs atjustification the other hand,
butwithoutreIatingonedotheother.
"There is...Iittto be saidon thisscore,sincethe SIovakMemurialIimits
itselto the repeatedassertionof Hungariannon-compIiancewith treaty
provisions,withoutbotheringto examinethelegalgroundson whichHungary
claimedta beacting(theseareonly examined ina subsequentchapter,andthen
onlypartially."
And in afootnoteitis added:
"Theillogicalityof theSlovakMernorialnthispointappearsclearly from para
6.90:
"It isnot the purpose of this Chapter to deal with these so-called
Sustificationsi.sufficetu show thatsuch aunilaterd terminatiothat
dates tothe 1977 Treaty ..isper se an extremdy senous breach of
well-estabIishedand fundamenta1prinripIesof general international
law."
It hardlyneedssayingthatuntilit hasbeenshownthat a purportedtermination
is unjustifithatterminationcannot be describedasabreach of international

5.04 This approach,neveriheless, isn&Iess appropriatefor the law of

T

however, itiscorrecthat:
" .,thinneeds qualification. A partymay in certainIimited circumstances

Hungary hasrecognised that.prima fa&, it acted in violationof its conventionaIobligations

unambiiguws acceptane of the materiainatureof thebreachd and "a recognition as tu the
imputabilitoyf...theactivitiescornplaineof".And from thisitfolIows,secondly, thatthere
is no pointinthisChapter in returningtothebreaches: theseareadmittedandrecognisedby
Hungary;the only question remaining to be dealt with here is whether exceptional
circumstanceexist tojust'@them.
5.O6 Although the HungarianCounter-Mernorialis rather uncIearhere, it
appearsthat Hungarycontinues tordy on thesamethree arguments to justify iageneral way
the vaIidityofthe prima facie breachesconstifnted by its suspensionand abandonment of
worksanditspurported teminationof the 1977Treaty:
l
l - Analleged"stateof necessity";
- An aIIeged fundamentalchange of circrrmstances;
- Ailegedbreaches of the 1977Treaty by Czechoslovakia.
It isnoted thattheverystrangeargument based on impossibilitof performance containedin
theHungarian Mernoriasleems tohavebeenabandoned initscounier-~ernorial'. However,
the latterdevotes,once more,manypagesto an attemptto show -againstal1logic -the lack
of reIevanceof ArîicIe27of theTreaty,dealing with"Settlemen tfDisputes".
5.07 SIovakia has responded to these arguments at iength in its previous
pleadin&. It is riunettiebsuse61 to re-examine them inthe Iightof thentw IegaIarguments
and,in particular,the new presentationofthe facts contained inHungary'sCounter-Memonal.

5.08 The use intheHungarian Counter-Mernori afl the "stateofnecessity"

byHungaryin itsMemonal tojustifthe terminatioof tde~reaty", initsCounter-Mernorial

I
althoiigh in essence Hungary Iimits itsetu referringback tu its Memonai - declaring

Hungarybetween13 May 1989(the suspensi ofon orksat Nagymaros) and 19 May 1992
(the notificatioof termination) were foundedon EItrngayts genuineconviction that the
completion of the ProjectwouId createa major ecologicd risk and that this mets the
requirementsofthe defenceof necessityunderthe Iaw ofState responsibiIity. Slovakihas
shown thatthe responsetothisquestionisnegative;Hungary has failedtu show theopposite;
it, infact,recognisthat "therealisatiooftheProject ..posedanenorrnous financial urden
whichthedeteriorating statbudget couldhardlyfinance"I6w , hichis noalegitimatebasisfor
invuking adefenccofnecessity.
5.12 Itis importantto explainoncemoretheexactsignificance of Slovakia's
l ,-
approach.Itis notargued thatHungary did notinvoke as itsreasonecologicalimpactsof the
Trtaty praject. Hungarydid surepeatedlyhm May 1989 onward(althoughit must be
recaiIedthat tttwas ody three rnonthsafieHungaryhadobtained theformal accelerationof
rhe work schedule - in the Protucol of6 February 1989 - aIso onthe basis ofecoIogical
arguments).Nor isit Slovakiasoint thatHungarydid notconsideritselfto haveanyoption
butto take unilateralctionsinviolationof the 1977 Treat-which,aRerall, betokens a type
of "necessifyifonly in iteveryday (not its legasense. Hungary nolonger consideredif

In short,Hungary"disguised" asituationofwhat itconsideredwas "economic necessity"as

5.46 Hungarydevotes severalpagesof itsCounter-Mernoria tl discussing
the "relevanceof Article27 ofthe Treaty" , hichconcems the "Settlementof ~is~utes"".
AccordingtothisArticle:
"1. The settIement of disputesin mattersrelating tu the reaiisatioand
operation ofthe Systernof Locks shaIIbc a function of the government
[plenipotentiaries].
2. If thegovernment[plenipotentiariesa]reunableto reach agreementon

5.47 Inresponsetu the SIovakassertionthat HungaryfaiIedto makeuse of

5.51 Hungary would have the Courtbelieve,in thus insistingon the
obligatorynature of the recoursetothe means ofsettlementprovidedby Article 27 of the
1 Treaty, that SIovakiwas resewingforitseIf"avetoovermodification o the ~roject"~~.
5.52 Once more, it must be stressaithat the prubiernis not asHungav

them. Theprinciplepactasuntservanda createsat the veryleast,such apresumption. Of

continue tu apply. If there ia "veto",it operates theperiod ofapplication of the
Treatyon thegroundsthat"everytreaty in forceis bindingupon the partiestitand must be
performed by them ingood faith"".
5.53 But it isquita differentsort ofveto that Hingary cIaimshûuld be
applied:not against the non-application of the Treaty but, on the contrary, againsi its
implementation. If such a theory were to be accepted,the stabilityof IegaIIybinding

7.01 The Partiesare in agreement that the worksat Nagyrnaros were
suspended by Hungary on 13 May 1989 and abandonedby ResoIutionof the Hungariari
Government on 27 October 1989. The evidenceis absolutelycharthat,thereafter,the
possibilityof Hungaryresumptionof work atNagymaroswas neverentertained,let alone
proposed,by Hungaryor madethe subjectof negotiationsbetween the Treaty parties.
Hungarytreated Nagymaros ashavingbeen abandoneddefinitivein7989 andnot a matter
for discussionother thtu fomaIiseitsabandonment by Treatyamendment(and afiethe
Hungarian Resolution of 20 December 1990,by Treatytermination). In

of the entireGlN Projeclagreedunderthe 19Treaty,induding Nagymaros,andatno stage

b. SlovakCounter-Mernorial,ra5.37-42. l 7.3Z First;relyingonthelackofanagreed record ofthe26 Octobermeeting,
the Hungarian Counter-Mernoria contends thatthe willingnesssubsequentlymanifested by
Czechoslovakiain its Note Verbale of 30 Octuber tu initiaa treaty on environmenfd
guaranteeswas nut made clearatthe 26 October meeting. Thus, su Hungary argues,faced
with continued Czechoslovak intransigenceH,ungq adopted a Resolutiorithe nextdayto
abandonNagymaros, and it seid its Parliament of the question. By the time the
Czechoslovak NoteVerbaleof 30 October was delivered,withits"compromis effer"itwas,
accordingtu Hungary, tooIate.Infa&,Hungary assertsthat theNote was:
"..deliveredat amomentwhentheoffeirna prty couIdbecertain that icouM
notbeincorporated intothedecisionto beadoptedbv theParliament 20hours
-aterS"
7.32 Ignoring this intimation ofbad faith, Hungary'sversionof events is
directlydisprovedby the evidericeproduced by both Parties. For in the vety ripening
paragraph of the 30 OctuberNote Verbaleitself, Czechosiovakiaindicated that it was
"presentingthe position"of the Governrnent of Czechoslovakia"expressed by the Prime
Ministerof Czechoslovakia ...at the [26 Octobermeeting]"60.It isapparent thatthe Note
constituteda formal confirmationof the officia!posititaken earlierby the Czechoslovak
PrimeMinister at the 26 Octobermeeting. There can,thus, bbeno sense in whichtheNote
Verbaleof 30 Uctoberwas delivered "toolate". Infact, Czechcislovakihôd had thethe

8.06 The immediate,vehementseriesof protestsmadebythe Czechoslovak

between the parties inSeptember and Octuber 1989, the detaiIsof which(and theidiemath)
have a directbearîng on the answers to the two questions put tu the Court under Article
2(l)(a) oftheSpecialAgreementinrelationto theGabEikovo section.

response to Hungary'sproposal, by whichit declared "itsreadinessto concludesuch an

Czec hoslovakia'sofficial position against the abandonment of Nagymartls, Hungary's
confirmationon 3 Novemberof its proposalto resumework at GabEikovo onthebasisof an
agreement on guarantees did not tie such resumption of work to the conditionthat

provision,a two-ticrprocedure of disputessetthent was envisaged
(subjecttu timeIimits),with uItimatsettlement tobe bycompuIsory

Hungaryproposedadding aspecialprovision:

Thiswas anobvious attemptto ratifa procedurethat wascontrary to the 1977 Treaty and
was a formal acknowledgment by Hungaryof the unlawfulnessof itsunilateralactsof

G/NProject. 9.03 As ChaptersWI and MI1 abovehive show Hungary was notmtitled
1
to suspendandthenabandon its worksunderthe Projectin 1989-early 1990. Accordingly,
I
whennegotiationsresumedinApril1991,Hungstry had longbefore,in breachof the Treaty,
ceasedto perfom itsobligationst~procee &dth theprojece.
9.04 The Hungdan Counter-Memona iandidly describesthe situationin
1991 as seen by Hungary, when negotiationswereabout1 torestart. Hungaryassertsthat it
was"self-evident"thatthe 1977Treatywas stilineffect,butadds that:
"In 1991, Hungary stiII saw some chanc ehat the 1977Treaty could be
amendedor terminated by mutual agreement and the partiecoutd agree an
importantrelaedissues...."
That istosay,Hungaryno longerregarded theresumption of the G/N Projectin accordance
I
with the Treatyasa possibiIity.Whatrernainedtube settIedwith Czechoslovakia,according
I
toHringary,concernedsuchmatters as"assessrnentand compensationoflusses,the fate ofthe
installationsalreadycompleted,the resolution of the problems of navigation and flood
protectionand the rehabilitatinf theaream'. The only!proposaHl ungarywas preparedto
rnaketo Czeçhoslovakia asa basisforsettlingtheirdisput-andHungary's sole aimin these
I
negotiations-presumed the total abandonmentof theTreaty Projecî bymutna1agreement.
There isnot a shredof evidencethat,afierit abandonedIa1constructionwurks on the G/N
Project, Hungary ever expresseda willingnes-to resume the Project jointly with
Czechoslovakia.

"Theconcept of divertingthe Danubeatthe sectionwhere bothembankments

9.14 The special relevanceof this offer is that itwas an attempt by
Czechoslovakia to have any deviationsfromthe OriginalProject, as well as the Project's
continuation , adethe subjectofimpartiasltudyand negotiationbetweenthe Treaty parties.
Hrrngary'sresponsewas a complete refusaltu enterinto anydiscussionthat involvedgohg

9.15 It hasto be re-emphasisedthatat no tirne afiitsabandonmentof the

any kindon the Project. AIthoughHungarydid propose joint (bilateral)studiesof the

Hungarygavenoindication thatiwasprepared to agreeto resumejointperformanco efwork

9-16 Furthemore, Hungary'sjoint study proposed was conditioned on
Czechuslovakias ltoppiridl workonthe Project. This was a newconditionthat, thenceforth,
Hungary irnposed as a prerequisitetu any further studies or the appointmentof any

9-18 Itmust be emphasired that th~rekty parfieswere in entireldiEerent
positionsconcerningthe Treaty'sperformance. Hungary had dreadyabandoned the Project
and, though its controof the Dunakiliweir,hadunilaterailypreventedthe damming ofthe

SECTION 7, Conclusionsinthe Li~ht of theAririiicabIeLaw
A. Czechoslovakia's Entitlement to Proceed With the ttProvisional
Solutionttin November1991
9.56 The Iegalbasis for CzechosIovakia'saction in November 1991 fo
proceed with the "provisional solution" was t1977 Treaty. This action was the first
concretesteptakên towardsputtingthe GabEikovosectionof theGINProject into operation;
andinArticle2(1)(b) of the SpecialAgreementitwas singledoutas thefirsof two actions
takenby Czechoslovakia concerning the "provisionalolution"on whose legalvaliditythe
Court was askedto rulen. It is uncontestebetween the Parîiesthat the Treaty winfull
forceandeEect atthetimethisactionwas taken.
9.57 Therewere four other particuIarlyimportant factors formingof the
context withinwhich CzechoslovakiaactedW, Hungarywas (and had longbeen)in breach
of the Treatasa resuIof a serieof breachesstartinon 13 May 1989 and cuIminatingin
Hungary'stotal abandonmentof the Project by mid-1990 (given formarecognitionin the
Hungarian GovernrnentResolutionof20 Dccember I990).
9.58 Second, the evidence now before the Court reveals that when
i~egutiationsresumedin 1991 theexclusiveaim of Hungary was to gain CzechosIovakiais
agreement taterminatethe Treatyand tubring theProject roanend. Czechodovakidsaim
was quitediEere itt :stu induceHungary turesurneworkunderthejointIy agreedpIanfor

The LeealBasisfor Praceedinewiih the "PravisionaISolution"
9.61 Until the time when ~zechoslovai<ia decided to proceed with the
I
"provisionalsolution"(in November 1991),there werea Rurnberof coursesof actionlegally
I
availabletoit:
l
- -irsf, tu attempto resolve Hungqis breachesthrough negotiatians;
I
just snch an attempwas madeby Czechoslovakiaduring 1989, but it
faitedbecause thenegotiationswere brought to an end by Hungary in
early 1990,who thenproceeded unilaterallyo abandon the Projectby
mid-1990;

breachesand to seekanarbitraiorjudiciaisefilement;
- Third. to continue to perform the Treaty asbest it could in the
circumstances, seeking a negotiated or a judicial settlementof the
damagesresultingfrom Hungary's breaches, and attempting in the
meantimeto mitigatethedamages to bothsides;
- Fourth,to accedeto Hungary'd semandsto terminate theTreaty andthe
Project; however,duringthe 199 1negotiatians ,zechoslovakia made it
clear to Hungary that this option was not acceptable and that it
continued tu insiston the perforinanceofthe Treaty (and the entire
Project) iaccordance with the Treatysterms.
9.62 Thus,thechoice tobe made came down to the second and options,
andin the circumstancesit was,in apracticaisense,nochoice atall. For duringthe fouror
moreyearsrequired to resolvethe disputeifthe second optionwere chosen, not onlywould
theGabEikovo sectionstructures,almost completedin1989, havecontinuedto deterioratebut

Hungary'sabandonment.For an abandonment a treaty of its obligations
thereunder isnot to be giventhesamelegaleffect as a validterminationof the treaty;
andin the present case,thisabandonmeno tccurred thepurportedtermination of
theTreaty.
9.64 As Chapter VI above has shown, Czechoslovakia's actions were in

of damages. To denyCzechosIovakia the rîght tu havesuacted would betu deprive it of ifs

9.65 Czechoslovakia'asctionin November 1991 occurredapproximately a
year before thenarrow "window" of time for dammingthe Danube would permitthe

actionto procd was in no sense a fai atcompli sufar asthe final implementafioof

obviously impossibletoimpIy arightof termination;
- Therefure, theTreaty cannot be denounced under the des codrfied

- Asa result, Hungq must finda bais outsidethe Treaty tu support its
contentionsregarding ifspurportedterminationof the Treaty;thesecm
onlybe foundin the nilescodifiedunder Articles60 to 63 of the 1969
Convention;
- At theçametime,Hungaryhas not estaldishedthat its "termination"was
inresponse to abreachof theTreaty by Czechodovakia (Articl60}, or
that thereexistedthe impossibilityof performance(Article 61) or an

10.16But this is notto say that th19 ky notificatiowas without le@

significance.In its communicationtu the Czechoslovakauthoriries, Hungary confimed,
definitively,rhat it had nointentionofcanyingout its oblunderthe Treaty Ofcourse,
as alreadyrhown inChaptenVI1 and VIII,by susPendi&andthen abandoning theworks
successively at Nagyrnarosand then at Gabi-ikovo,&ungary had breachedits Treaty

this,froma strictlylegalstandpoi,twouldstiHhavebeeripossib foeHungary foreturnto
the Treaty. The Projecrschedulemaynut havebeenrespected,the prublernsofcompensation
maynot have beenaddresseci,but the Treatycontaineciits ownsysternof of

I
notification,however,it becarneclearthat Hungarjrwould no longercarranyofits Treaty
obligationsandthat thdoor was finnlyshuto anyarrangements ornegotiationbasedon the
Treaty. And this was so despite innumerablegesturds of good faith on the part of
Czechoslovakiawho neverhad ruledout eithea postponlmen otf the daof dammingor a
possiblere-examinationof peak mode operationor, obviously,of a retum to theoriginal
TreatyProject.
21

wmpIetely excludedandCzechoslovakih aadnochuice butto proceedto put intooperation

Czechoslovakiatu obtainthe performance - appruximate as itonly couldbe -of the 1979
Treaty,which remained validandbinding between theTreatyparties.
10.18 Thus, although the 19 May notificationhad no effect on the Treaty's
vaIidiryit nonethelessconstitutedthe admission by Hungary of its definitive,irreversible
breachesofits Treatyobligations.Hungarycould not byitseIfputan end tothe Treaty,but by
itsconduct itreveakd inthe dearest possibw leay itsintentionnottu performthe Treaty.
Through the simpleapplication of the principleof good faith,the followingconsequences
thereforefollow:
- F&, Hungôry forfeitedtherightto rely inthe future onthe Treaty
whoseapplicabilityit denied(venire contrfachrm proprirrmnon vaIat);
in particular,thad no rightto attackthe puttinginto operationof

Effect

10.30 No matterunwhatdateit occurred,the terminatiof the1977 Treaty
couldnot inany eventhavehadretroactiveeffect. Thiscustomaryprincipleof international
lawiscodifiedinthesetermsbyArticle70(1)ofthe 1969ViennaConvention:

10.31 Comrnenting on the initial draftf this article, the Es Specid
Rapporteur , iHumphrey Waldock,expressed theopinion thattheseprovisions:
" ...arlargelyseifmevidentndtheir main import&nceis tounderlinethat the

Article33(d)ofthe Harvard ResearchDraR Conventionadoptedthe sameapproach:

"Thetemination of a treat...does notaffectthevaIidityof@ta acquiredin

that date,the foIlowingsituationprevaiIed:
- The workson the Wikovo sectiohad almost beencompleted - the

ben constructcd,with orrlya fewthingsleftu be cornpletedand the
actualda-g of theDanube at Dunakilitiernaininu be out
(originalscheduledforOctoberf 989);
- Incontrat, due tu the considerabdelay incarryingout the work at
Nagymarosforwhich Hungary was responsible,andrelatedprojects,the
constructiontherwas farfiombeing completed;
- Czechoslovakia had undertaken prelirninarstudies into alternative
schemes for putting GabEikovointo operation and, beginning in
Novernber 1991, had proceeded to the "provisional solution" which,
however,was not to be put into operatiountilthe end ofOctober
1992.
10.34 These three aspectof theperformanco efthe Treaty presendiferent
problems asregardstheeffects(orwhatmight havebeen theeffects)oHungary's purported
termination. At thetimeHungaryclaimedtoputanend to thTreat yNagymarosbeingonly
about 20% complete- it mightbe maintainedthal, excastu matiers ofincurredliability,the
terninationof rhe Treat-if vali-would haveended Hungary'sobligation tu completethe
works atNagymarosforwhich itwas responsibleundertheTreaty.
10.35 But, as regardsthe works at GabEikovo,the situationwas entirely
different. Thertheworktu be carriedoutbyCzechosluvakiawasabout 90% compIete when
Hungary issuedits19 Maynotification.Thousandsof hectaresof former famland hadbeen
appropriate or theProject. Iwas absoluteloutofthe questiontoallowthingstoremain in
thatstatewithoutcreatingan ecologicalcatastrop-erealand immediate,nothypothetica-
just as iwas out of the questioto returntu the statuquo ante,whichwas technicaIIy,economicdly and finançiallynotfeasibld'. In thisiniatioq Czechoslovakia(and now
l
Slovakia)had the vested rightto seethatthe remaininework to completeGabfikovo was
carried out. Thisconsistedlargelyof the damming of the Danube at Dunakiliti. Due tu
Hungary'r sefusal,thedammingcouldnot takeplaceat thissiteCzechosIovakiao 'sdymems
of ensuring that its rights were respected- without infnngbg on Hungary'stemtorid
sovereignty-wasto proceed to theirnplementatioonf Vapant"C",once itwasconvincect ihat
Hungarywouldnotcarry out itsobligations.
l
10.36 The 1977 Treatyhadbeen almost completely camed out sufaras
GabCikovowas concemed (thanks largely to the efforts of Czechoslovakia); and
Czechoslovakiacouldnot be deprivedof the fiuitsof its laboby theunilateradecision of
Hungatyto endthe Treatyprematureljr. Otherwise ,his wouldbe to annul retroactivelythe
performance of the Treaty by CzechosIavakia and hencI to give retroactiveeEect tu its
temination invioIatioof theprinciplsetout in&cIe 70(1) ofthe1969ViennaConvention.
10.37 Thesarneconsiderationsapplyto thbquestion ofthe validitof Variant

acknowledged byArticle2 (I)(b)ofthe SpecialAgreement. Consequentlyd, espiteHungary's

protests,this decisioatleastwas takenundertheTreaty,whichunquestionably was at the

20.38 Itisperfecticlearthatitwas preciselybecaus Hungaryknew thatthe

attemptto tie thwaterquaiityprobIern tutheGIN Project isobviouslyinvalid.
12.05 Indeed,itis notpossibleto seethe relevanceof theexamplesprovided
by Hungary. Hungaryclaims nomore thanthatits own dredgingin the 1970s "led tothe

have an adverseimpact. But suchlarge scde dredgingwas notenvisagedbyandnor was it
carriedout withinthe fiameworkof theGIN Pr~ject.
12.06 What littlcredibilityHungary'sclaimshaveis negatedby thissimple
fact. Its contentioof "seriousrisk"isbased onthe assertionthatProject"dredging was to
have taken place" downstream of~a~~maros'~. The JointContractual Plan did originally
anticipatethe dredgingof 6 miilionm3hm the riverbeddownstreamof Nagymaros. But
Hungary hasalready dredged some20 miIIionm3hm this stretch for industriaVcommercid
purpuses". Asrecorded ina 1989 studyprepared by theHungarian scientistsSomlyudy,& d:
"As a resriltofintensivedredginoverthe past decades,thewater ievelof thegresentsection

12.25 The retevance to Hungary'sIegd case ofits presentation ofaIIeged
Projectimpacts to flora and fauna appearsto be as followsn: Hungary'sinvocation of
necessity isbased, in part,on the "severedamage" which was "anticipated "o fiora and
faunaT3 w,hilstitssuspensionof worksisjustifieby the allegednon-fulfilmen tfArticle19 of
the 1977 Treaty"conceming thenaturalen~konrnent"~~.
12.26 But even within the gqeral tupic of mils, floraand fauna, the legd
relevanceofthe individua1 impactsposited by Hungarymust be questioned. For example,
Hrrngary seesanadverseimpactinthe snbmergingof 20 "isIandsanndIargeparts of shoreIine
in the Nagymarosreservoir" . But th inundation wasai intcgraIand necessa payrtof the
Project towhich theTreatypartiesknowinglyagreed. In anyevent,Article 19 ofthe Treaty
cannotbe appliedto prohibit thisresult,for todo so wouldhavethe effect ofpreventingan

considers to be the scant attention paidtu flora and fauna inthe SIovak ~ernoria~'~,but

assessrnentof anticipatedimpacts but,for themain part,atanattempt to disprovethe factof
theTreaty parties'agreementto incorporate thevariousremedial masures intotheprojects4.
This is indicativeof the centralrole in Hungary'sargumentsplayedby itsconcept of the
"OriginaP lroject", hichIargeIyignorestheremedial measures agreed bytheTreatyparties (in
partas a responseto Hungary's1985 EIA). ,Onlyfive paragraphs of Hungary'sCounter-

to peakoperations6 andtwo relateto internationaelxperienceof dubious relevances7. The

12.36 Hungary's allegationof adverseProjectimpact tofoiraand fauna inthe
Szigetkozand,in particular,tsactivefloodplainaremisleadingand greatlyexaggerated. A
"fundamenta cl angeintheoriginallandscapeofthisfloodplain"is predictedlo5.However,the
referenceto "originalIandscape"isverymisleadi nrgthefloodplainreferredto was reduced
inthe 19thCentury toa stripalongtheDanube just1-5km wide. Even wittiinthisslip, there
is no truly original Iandscape. For example64% of the fioodptainfurestcunsists ofone
species type- a hybridpoplar,whichis a eultivatedand harvestedtree,specificaIIumamral
for the floodplainarea. A detailedaccountof the changesin the floraand faunain the
floodplainas aresuitof humaninterventionprior to thedammingof the Danube isset outin
VolumeII1hereto,Chapters4 and 5.
12.37 Thisis not to saythat the flora and faunaofthe region, asof1989 or
1992,were not of great importance. This is not questioned.And preciselybecauseof tkis
importance and ifs recognition by Czechoslovakia(and now Slovakia)the impacts that
Hungary now aIIegesand, inpatticular,the imminent "declinein biodiversity"cannot be
'substantiatedlo6
12.38 Onceagain,Hungary's allegationsassumea drop of surfaceandground
waterlevels, althougha new emphasis is placedon the valueof regularlyfluctuatingwater
levelsand the ecohgicaIIyharmfblnature ofundenvater weirsl". Indeed,Wungary considers
that the "determiningecoIogicaIfactorof AoodpIainsis the cyef floodinganddrjring",that
is surfacewaterfluctuation1". Slovakiaaccepts thatfluctuationpiaya significantrole But
the flooding patternsthaexistedpriorto the implementafion ofVariant "Cu were inno way

to morefrequent andmore extremeflooding,which was in turnaggravated bytheisolationof

12.64 In a reportdatedSeptember 1994 prepared for the GeologicaIInstitrite
of Hungaryby a Hungarianscientist(2. Balla),a previouslyunknownfault line (given the
name "Gyür-Beçskefault line")in the region ismentioned for the first time. This timely

the convenienteffectof reducingthe distancebetweenGabEikovo and a "known" fauIt Iine
from 45 km (thedistanceto a previouslyhypothesisedfault IinepassingthroughKomho) to

SECTION 1.
13.01 Slovakia hasshow intheIntroduction to thisRepiythatcertain of the
adverseProject impacts allegedbyHungary are notrelevantto itslegalarguments,regardless
ofwhether they can bc proved:for example, ifthe 1977 Treaty partieschose to exchange
receipts from hydrodectricity productionfor the Iessimportant economic benefi ts Eom
agricrrIturandforestry production(qtoO non)t,heywere atfuT1liberttu do so. From this it
naturaly foIIowsthat the impactaIIegedby Hungary to agricultureandforestrydo nut have a
legal linkageto itsdaims of anecoIogica1 "stateof necessity",or to allegedbreaches by
Czechoslovakia of the 1977 Treaty. Hungary does not claimthatthe adverseimpactshere
wereunknown in1977. Hence, itis difficuto see how thesesarne impacts couldsuddenly
create astateof necessityin1989'. Andthere isnoprovision inthe 1977 Treatyrelatingto
agricultureor commercia forestry. Hungary's argumentsin relationto Articles15 and 19
cannotbe appIiedhere. Hence, agricultureand forestry aretreated separatefrom the other
adverse"environmental"impacts aIIegedby~un~a$. However,regardless ofthe above,it is
stress& chatthe Project as it developed did not have adverseimpacts on agriculture and
forestryproduction.

section briefly reviews these technical aspectsbut, first, considers the overaaims and
relevance ofHungary's considerationof a topicthat was totallyabsenthm the Hungarian
Memoial.
13.17 Hungarybases its new emphasis on riverbeclmorphology on an
allegation as to the "justificationfor the "OriginalProject"contained in the Slovak
~ernorial~'. Slovakia,itisdaimed, contendsrhatfloodcontrolandnavigation measures led
to the Iowering of the Ievel of the Danube downstream of Bratislavaand,in turn ,o the
reductionof theground watertable,resuitinginahamihl impacton theenvironmen atsweII
asonagricultura endforestry. From this,Hungary arguesthatSlovakia'rseasoningis basedon
threeassurnptions :i)that rneasuretu improveflood corttroIand navigationhad tubetaken;
(ii)that these measuresnecessarilyletuthe reductioninthe ground water table;and (iithat
only the 1977 Treatycould solvethe three problemsof flood control,navigationand the
reductionof thegroundwater level(andin so doing alsosolve theenvironmentap lroblemsof

13.18 Of theabove threeassumptions ,he secondis said by Hungaryto be
"criticat"becauseoftheIinkagebetween"worksportrayed as essentialfortheregion'ssuMvai

environmentalprublems ..whichresult fiomthe drapin theground watertable";andHungary
contendsthat, iitdisproves thislinkage,"much of thereasoningcollapses"on whichSlovakia
supposedlybased its "justificatiofor the Original~roject~'". However,Hungary's initial
premise isfaIse. SIovakia dow nut seek tû justie the Gm Project. The Treatyparties

SECTION 3. The AIIe~edivUnnecessarvBentfits: Enewv, Navigation and Flood
Con troi
13.26 The Hungarian Counter-Memurial devotes a surprisingly Iong sub-
sectionto a consideratioof the Project'sbenefitsintermsof electricityproductionthebasic
purposeof which isto showthattheamountofenergy tobe produced was at bestrathersmall
and, in facteven unnecessary. The justification for this expandedtreatmen-even though
Hungary acceptsthat the"[bjroader issues ofenergy poIicyarenot before the Court in this
case" -isthatthere were in"theSlovakMernorial'p sejorativereferencestoHungarian energy
policy". Hence,Hungary argues there ia need"tuputinto perspectivethe value of power
generationthroughthe OriginalPraject andthrough Variantc"" .
13.27 But the Slovak Mernorial can be searched in vain for any such
"pqorative referencesnS6. Slovakia merely noted that Hungary did not expioit the
hydroele~triîpotential of irivers". As Slovakiaexplained,the sole purpose of its fucuon
thisissuewas to explainthat,whereasin 1977Hungaryhadagreed todevelop itshydroelectric
potentiaiinthejointGR\T ProjectwithCzechoslovakias,incethat dateHungaqhasinvestedin
other foms of energy suthat, in 1989, its need for theeIertrictoybe generated under the

allegation. Indeed,Hungarynow admitsthat, at thetimeof itsTreatybreaches,it did not

13.28 Moreover, Slovakiaconsiders thak there is no need "to put into

the riverto atternptto meander. The irnpoundment df water in the stretch behindthe
