SECTION 1. Summarv ofthe Caseas SlovakiaSea It

The Case isa "Treatv Casettand the 1977 Treatv is the Central
Element oftheDispute and of itsResolution

The Court isrequestedto decidt onthebasisof the Treaty andrules

(b) whether the Czech and SlovakFederal Republicwas entitledto

operationfrom October 1992 thissystem, describedin the Reportof the
WorkingGroup ofIndependenEt xpertsof the Commission ofthe European

(2) The Court is dso requested to determine the legd consequences,
incIudintherightsandobligationsfothe Parties,xisinhm its Judgmenton
thequestionsinparagraph(1)ofthisArticle."

1.04 The1977Treaty isthusthecentraielementofthedisputewhichdivides

theParties.The Courtis requesteto determinwhetherHungarywas entitleto suspendandsubsequentlyabandon itsobligationsarisingfromthe 1977 Treaty and then uniiaterallto
decide on its "termination". The Court idso asked tu determine whetherCzechodovakia

was, forits parlegallyeritidedtu secuan approximateapplicationby resortto aprovisional
solution, Varian"C". And, finally,the Court askedtu decidewhat the IegaIconseqrrences

areofitsfindings.

1.O5 Not only does theapplicatio- ornon-application- of the 1977 Treaty
constitutthe veryobjectof thedisputesubdtted to theCourt butf ,iirther,thePartieshave

agreed that the Treaty forms the essentialbasis of the applicablelaw. Certaidy, the
introductoryclauseto Articl2(1) oftheSpecialAgreement quotedabove does not make the

Treatytheexclusivebasisfortheresolution ofthatdisputesince italso mentions"nilesand
principlesof generalinternationalaw as weilas such other treaties asthe Courtmay find

applicable"B. utthisismerelybecause,astheCourt haspointed out:

"..a mIe ofinternationallaw, whether customq orconventional, does not

which have, for the mainpart,beencodifiedin the 1969 ViennaConvention on the Lawof
Treaties.

1.06 Ttis nonetheIess tme that,through the agreementofthe Parties inthe

SpeciaIAgreement, the 1977 Treaty constitues both the principd object ofthe dispute
betweenthe Parties andthe verybais ofitsresolutionwtiichthe Courthas been requestedtu

andysisof the caseis the 1977 Treaty,on whichHungq hasendeavoured to cast acertain

suspicion,inparticulbymeansof its constantallusionsto pressuresallegedlyappIiedbythe
SovietUnion at thetirneofitconclusion.Leavingasidethefactthatthese allegedpressures

1.O9 ThisTreaty,thevalidityofwhichhasnotbeencontestedbyeither ofthe
Parties,imposespreciseobligationofresult,theprincipalof whicharecontainedinArticle 1

(describinthem)andArticle5 (allocatingthembetweenthe Treatyparties). Intheiressence,
these obligationsconsistof the constructionof tG/N Projectwhich "shallcomprisethe

GabEikovo system of Iocks and the Nagymarossysternof locksand shallconstitutea single
andinvisibleoperationalsysteof works"(Article1).

1IO Concerns inreIatioto theenvironmentdo not fum the object ofthe

Treaty even ifas Hungary recognises,such concems were by no means overlookedby the
draftersof the Treaty,who -a rarethingfor the era-accordedthem a placein the Treaty

(ChapterVIIthereof andArticle15). Furthemore,oneof the most important objectivesof
the Treaty was protectionagainst floods- an essentid factor in terms of the hurnan

environmentin the light of the history of catastrophicfloods inthe area before the
construction of theGN Project. The Treatyparties alsointended to improve navigation

conditions- the Project areabeing oneof the remairing bottlenecks Endering the smoofh
functioningof the Rhine-Main-Danubenetwork (then under consideration) - and tu draw

additional benefit hm their naturalresources by developmofta renewabIeand pollution-
freesourceofenergy(the GIN Projectbeingeonceivedtosupplythe particularlyvaluablepeak
production electricity).

1.11 Thesepreoccupation sere of coursesharedbythe two Treatyparties.

Hungarymade this decisionata time when the means of investigationand evduation of

Mernorial.

SeeSlovakMernorial, para.6.08. 1.16 Hungaq'spositionderivesnut fiom a "scientific"ecology buhm a
"politicalecology. TheHungarianGovemment,overwhelmed with seriouseconomic and

financialdifficulties,had decitodblarneits inabilito meet itsobligationson supposed
environmentaolbstacles. It didnot hesitto put pressureon scient& bodies,in particular

theHungarian Academyof Sciences, toprovidea veneeroftmth to itspositionwhich,infact,
was inspiredbypoliticalandeconomicfactors7.

2.27 This gavethe Hungarian Governefit the opportunitytu "bringon

board" the ecologicrnovement, tu attributetuCzechosIovakithe reasonsfor the prevailing
discontent, anto lightenitundeniablyheavyfinanciaiburdens(dthough, inrelatioto the

Project,thesewereburdens sharedbetween thetwo Treatyparties).Once thismuvernentwas
set in action(andevenencouraged)t,heHungarian Goverment was unableandunwillingto

resistthefurthepressuresof the environmentaalctivists,whetherHungarianor foreign. No
oneis unaware oftherole playedby theenvironmenta ml ovementsinthedemocratic protests

againstthecomrnunistregimesin Centraland EasternEuropeand,in particulari ,nHungary.
Put forward- quite wrongiy-as theemanationof the regirnethein power,the G/N Project

became a symbol tu bedestruyed. And,dthough the HungariatiGovernent knew that the
clairnsagainstthe Praject hadno scientificbasis,it neither muld norwishedtooppose the

works at Nagymaros,then at Dunakiliti, and then by abaridondIgworks,andfindIy by

purportingto termina tnilateralthe Treaty. Not one of the stephada credible basis-
eitherinfact, orinlaw.

1.18 Oneexampleof particularsignificanceshowsthatthe so-calledmotives

"environmental" obstacle to the constructionof the GabEikovosection of the Project.

2.13 At variouspoints in its Mernorial,Hungarystresses the "integrated"

natureoftheProjectwhich,asArticle(1) ofthe1977 Treatyprovides:

"..shallcomprisetheGabEikovo systemof locksandtheNagymarossystemof

(emphasisadded);

or,astheHungwianMemurid describes iîasystern:

"combininbgothupstrearnand downstrem elemens ina systemof peakpower

2.14 Thisemphasisisjustified.Certainlntechnica lermstheProjectcould

be dividedintotwo distincparts- beingthe GabEikovo and Nagymarossections. It is this
divisionthatisreflectediArticlesl(2)andl(3) of theTreaty. But in legalandeconomic

termnthese two sectionswere not divisible. inparticiilar, the essentnature ofthe
cornpletion of Namarus tu the Projectmust be stressed: on theone hand to enable the

productionof peakelectriciat ~Eikovu, which was impossiblewithoua downstream weir

2.15 Hungary,moreover,recognisesthevitalimportance of theconstruction
ofNagymarosto the Project:

"In particular tNagymarosBarrage was essentidtu the Original Project,
which was,as demonstratedinChapter 4,conceivedas 'asingland indivisible

This puts inits tme light whatHungarynow cdls "the cautious provisionai and partial

2.31 Hungary iscorrectinsayingthatthe protectionofthe environment is

notthe essentialobjectof the 1977Treaty.PiototheTreaty'sconclusion,thepartiessirnply
took care to reassurethemselvethatthe Projectwas compatiblewith the requirementsof

indude the obligatitu ensure vigilantattentiontu the envirument. For exampIe,the word
"monitoring"("contrôle" inthFrenchtext)and"appropriatme aures" appearing inArticles

15 and 20, clearlyillustratethat the partieshad to ensurethe irnplementatiof these
1 provisionsby reachingcommonagreement asto anynecessarymeasures while at thesame

timemaintainingthe essentialobjeof theTreaty:theconstructionand operationof thGM

2.32 Hungary presupposesthe directoppusite of this. It proceeds to

substitute the preservationofthe environmtstheessentialobjectotheTreatyand, whatis
more, arrogatesto itselfthe rigtodecreeuniiaterdlywhat suchpreservationrequiresand

The 1977 TreatvCreatedRiehts InRem

2.35 Hungary goes tu greatIengthsto establisthat the"1977 Treatywa
not a bourldary treaty, deIiberanotH since,accordingtu Hungary,"the partiescouIdnot

agree on the originalHungariademand that the boundarylinebeshiftedsuas tofoHowthe

wrong. The parties hadagreedtu rejectthisdernanas is quitecIeafiom theTreatyitself,in
particular,Articl22(1). The originofthe problem isattributedto Czechodovakiawho,

allegedly,"wasadamant in itsrefusalto contemplateashiftintheborderline. But even the
Hungarian Mernor aishowsthat inrealititwasHungarywhorefusedto modifytheborderline

"because therewas no suitableHungarianterritorythatcouldbe offerd"incompensationfor

the loss that CzechoslovakiawuuldhavesuEered asa resultofthe boundary beingshiftedtu

2.36 The reasons for Hungqis inaistence on this point are uncIear,

particularlsince itwould appearevident that,althoughit did not, of itself, establiah
boundary,the 1977 Treatyestablishedobligations and rightsrelatingto theregime of the

boundary and tothe use of thconcemed territory.Thishasthesame legd consequences,as
Slovakiaestabiishesbelow.

2.37 Mungws insistence ispresurnably a tactic deztineto introduce its

most surprising arsment regardingState succession, under which the 1977Treaîy is
artificidlyctassifiedamongthose treatiescreatingrightsexcIus&vpersonamandnot rights

2.39 Article22 ofthe Treaty is erititled"Determinationof the boundq line

This isfollowedin sub-paragrap a) by confirmatioof the existingboundaryand insub-

2.40 Asidehm these provisionsconcerningconfirmationor revision,this

reasons.

that,whereasthe new character othefiontieconstitutean importantelment oftheTreaty,

merely logicd but inevitabtu postpone fora frrrtheragreement the definitivefiofnthe

2.44 Thus,the essentiaboundarycharacter ofArticle22,even ifnot of the

Treaty asawhole,is clear.The attitudeofthepartieshowsthattheywerewellawareofthis.

The 1977 TreatvEstablishes aSpecificTerritoriaIRe~ime

2.45 However anxiousHungq isto minimisethe territorial nature of the

2.47 Moreover,Hungary's reluctantadmissionas tothe change incharacter

2.48 The1977Treatyprovidesfortheconstruction andsubsequent operation

2.49 The rightsand obligations concerninuse and restriction ouse are

A. Huneam'sErroneousAnmilvsio sf theJointContractualPian

2.58 Hungaryrepeatedlystressesthe importance of the JointContractual

Plan,"thebasisfor a greatdeal ofthe substanceof the Projectand "theprincipaltool for
implementint ghe obligatioforeseen"inthe 1977~reaty~'. Thisis correct:the1977Treaty

isa Cameworkinstrument, imposhg generd obligationson the parties,withimplementation

1(4));

- the "regulationsgoveming the organkation and activities"of the
"permanentand joint agencies for the performance " of the
Plenipotentiaris'nctions(Articl3(2));

- the "preparationof the joint investment"thatis to say,"the main

dimensionsof the works of the System of Locks, the technical
specificationoftechnicdequipment,the finalprojectwork schedule
and responsibia;for thewsts referreto inarticle12, paragraph2"
(Article4(2)(a));

- the basicdatafor "(1) Orderingthetechnicd equipment,construction
materids,machineryand steelworkforthe Systemof Locks"and "(2)
Drawirtgupthe constnrctionplansandspecificationsArtide 2(2)@));

- "thecostsof canyhg out thejoint investmet (Artide5(6));

SystemofLocks"(Article1 S(1));

- the means inorderto "ensurecornpliancewith the obligationsfor the
protection of naturaerisinginconnection with the constructionand
operafionoftheSystem of Locks"(kick 19).

2.59 At the same the as it rewgnises the importance of the Joint
ContractualPlan, Hungaxyatternpts to Iimiits IegaeIffect, in anatternptu escape its

respunsibility.And indeed,if the Treaty itçelis ody a nonself-executing5amework

thatthe Treaty partieacccptednoIegd obligationfor the breach for whichthey wouIdbe

respunsiMe.Thisis cIearIanindefensibIpeosition.

2.60 Hungq contends thattheJoht ContractualPlanissubordinatedto the
7977Treaty (and the 1976 Buund- WatersManagementAgreement), which iscorrect,

although notin thesenre intendecl yHungary. Further,Hungary contendsthatthe Joint
ContractuaPl lanisnoa conventionailnstrumentr treaty. This,bycontrast,isincorrect.

2.61 Accordhg to Hungar :y

"The JointContractudPlanwas not concludedin the formof an interstate
treaty, and was notas such ariinstrument governed by iriternationd law,
whatevermayhavebeenthe statusofthe 1976Agreementfor the drawingup
ofthePlan. Itwas subjectmerelytu'approval'nconfomity with nationdIaws

andregdations (Article4(3)), rather thsignaturandratification,asinthe
caseofthe 1977Treatyitse1P9."

But thinisto overlookArticle11 ofthe Viema Convention (whichonthis point,Iikemany

others,iindeed acodificatioofexistingcustomaryinternationllw):

"The consentofa Stateto beboundto atreatymay be expressedbysignature,
exchange of instrumentsconstitutinga treaty, acceptance, a~proval or
accession,rbyanyothermeansif soagreed7'."

2.62 TheJointContractuaP l lantherefore appearstobea treatyinthe fuii
senseofthe tem, and,even,inthe narrow senseofArticle2(l)(aof the Viema Convention,

thePlan is:

"... internationalagreementgovernedby internationallaw and concluded in

B. Hun~arv'sErroneousAnaiysis of the Other Related A~reements
and their Relationshito the1977 Treatv

2.73 Like Slovakia, Hungary accepts that "the 1977 Treaty was not
concluded in a vacuumbut wa~ part of a mat& of bilaterd and muiilateraltreati..."8'.

However,udikeHungq, SIovakiaconsidersthat th"matrix"incIrrdesagreementconcluded
both before and after the1977 Treaty(although these comprise two distinctcategories).

SIovakiadso hds Hungarjt's analysisofthe reIevanceof these agreements tobe odd and
seIective.

2.74 In linewithits utterindifferetoethechronology of events,Hungary

tuArticIe34of theViema Conventionon SuccessionofStatesinRespectofTreatiesof1978.

The Viema Conventionis not a treatyinforce and, assuch, is not applicablein relations
between SIovakiaaridHrrngaty,except when the mIes set outintheConvention aremies of

general internationtaw. In fact,the Convention codZed, tu a largeexterit, the existing
custornaq law. Hungq, nonetheless,sçerts:

"Not ody is theConventionitseifwidelyregardedaslegislativeincharactand
not as a statementof existinggeneralinternationallaw,butthereis littleor no
supportforArticle34 asbeingdeclaratoryofgeneralinternationaaw6 ."

But,thisassertionisnot accornpaniebyanysubstantive analysis.Therearesound reasonsfor

Siovakia to takjust the oppositeview,inparticulaasfaras theapplicationofArticle34 in
concerned.

3.08 inits commentary to the 1974 dr& ofthis provision (at that time

Article331,theInternationaLlawCommissio cnncludedthat:

"..althoughsomediscrepanciesrnightbe found in State practice, still that

practicewas suEcientlyconsistentto supporttheformulationof a mle which,
wirhthe necessaryqualification,ouIdprovide thattreatiesinforcat thedate
of thedissoIutionshuuldremaininforce iwsoiure with respecttu eachState
emergingfiom thedissoIutiun.The factthat thesituatiomay be regarded as
one of 'separationofpartor partsof a Statetratherthan one of 'dissoIutionl
doesnot dter thisbasicconclusion."

The key tothe Commissian's adoptionof this positionlay in what, in 1972, hadbeenwo

differentarticles (Artic27 and28) whichdealtseparatelywithdissolutionof a Statewhen
the continuity principshould apply, and sefiaratiof part of a Statein which event the
"cleanslate"doctrineoperated(becausea new Stateemerging hm sucha separationhadbeen

consideredasbeingin the same positionasanewfyindependent State).

was IittIerecentSîatepracticetu jnstiSfit. TheCommissionacceptedthia sndamdgamated

the mu situations, opting for a continuity principleasthe uriiform nrle for both cases

(dissolutioas weIIasseparation).

3.10 The Commissie onvisaged onIy one exceptionfiom the continuity
principleinthe event of separation.Thiswas reflected inparagraph 3 of the iinai drafof

Article33 whichprovided that:

"..i fpart ofthe temtory ofa Stateseparates hm it andbecomes a Statein
circurnstancewhichareesseniidly of the same characterasthose existingin
thecase oftheformation ofa newIy independen Sttatethesuccessor Stateshall

Inotherwords, ody inthatsituationwould the"cleanslate"mleapplyandnotthe principle of

continuity.As SirFrancisVallat,theexpertconsultante, xplaineto theConference:

"...fromthewording ofArticle33 andthe commentq tu it, it was cIearthat
paragraph 3 was not intendedtu apply tothe case where a predecessor Statt
ceased tuexist. ConsequentIyit wouldnot appIyto thecaseofdissoIutionofa
%teg ."

3.11 The InternationalLaw Commission's approach was in principle

approvedbythe ViennaConference held in 1977-1978. The proposais to alterthe basic

principleof this articlewererejectedby the conferences. In defending the Commission's
approach and inagreemenw t iththeprevailingview,the ddegate of theUnited Statesstated

3.12 The view that the continuityprinciplewasjustfied,irrespectivof

whether thedissolutioofa Stateorthe separatioof partof aStatewasinvolved,was shared
by the majoritof delegations. Andtherewas anear consensusamongstdelegationsthatin

thatthe successionwouldoccur inaccordance withandto the extent
determinedby theexistingmIesof internationallaw;

3.54 The conclusionsthat Hungaryseeksto draw from the formulachosen
by the Partiesin the prearnof the SpeciaAgreement areinvalida. Itwas evidento the

Partiesthat thedraftingofprearnburaragraph2 oftheSpecialAgreement had to be without
prejudiceto the questionssubmittedbythemto the Court. The failureto mention specifically

that Slovakiahadsucceededto the 1977Treaty cannote interpreteasan agreement that it

economic and environmentalissues (inthat order) andrecommended that a comprehensive,
twoyear environmentalimpact studybe c&ed out. But it did notfind thatthe Projecî

cngendered my irremediable riskstu the environment. To the contrary,in this paperthe
HungarianAcademyexpressedthe view that "therealor supposedenvironmentaidamage

coming from the [G/NProject]constructioncan be decreasw eitha greatprobabity or can
beavoided ..."12The focusofthepositionpaper,however, was onthe costofsuchavoidance.

4.19 In factthe central concenof the positionpaperwas simpIythat the

Project might not be cost effectiveparticularfwhen the additionalcost of necessary
protection masures outsideoftheProjectwastaken intoaccount:

"The 30 biIIionForintstu beborneby theHungarianparty ..doesnot contain

Thus, whileit istme thathe positionpaperrecome~ded the suspensionor abandonment of
theProject, thiwas oneconomic,not environmentai,grounds. Thepaperconclnded:

"It is doubt...thataIongtem invesfrnw enhichonIy consumesandfreezes

4.20 Hungary hascIaimed thatthispaper"was completelyneglected by the

The Impact on the G/N Proiect of the On-Goinp Environmental

4.31 Hungarycontendsthat thedesignof the GM Project datesback to the

that in the 1977Treatyartalready archaic designwas institutionalised.Asihm being
factuaIIywrong, this contention confIiwith Hungary'sown Treaty analpis. For the

HungarianMemonalconectlypoints outthatthe finalProjecdesignwas not laiddown bythe
1977Treaty, buwas containedinthe JointConfractuaPI=. As Hungarynotes:

"TheJoint Contractua Pilanhad not beenconcluded when the 1977 Treaty
enteredinto force,asArticle3(2) reveals.The Plan was not even a single

document, butmore afilingsystemof specificatio,nd was ofenormoussize.

5.10 There can beIittle doubtfiom both the text and thetone of this
Resolutionthatthedecisionof13May was seenbytheHungarian Governmen tsthefirsstep

toward aplannedterminationoftheNagymaros sectionoftheGM Project. The studiestbe
cornrnissionedereairnedatamending theTreaty;andin thelighof item(v) aboveiisclear

that the sole reasforamendingthe Treaty was tu terminateNagymaros. Item fv)was a
referace backtuthe PwlîamentaryResolutionof7 Octuber 1988 andto the eighpointsset

out inthe Goverrunent'reporf(appruvedbythe Parliament).Point 1inthe Goverment's
reportwas thefollowing:

"Thebarrage system must beconstrticteas itstandsin the initialconcept,
includingthe NagymatosBarrage;namely,to enablepeakcapacityoperation.
Without fuIIimplementation of the Project the techriicd-economicand

developmentgoalsformingthe basisofthe decisioon the investmentcannot

Thus, item fv) ofthe Resolutionwas ine£îecta request to Parliamenttu approve the
efiminatioof Naparos hm theProject. ThisinWrn, cdIedhto questionthe viabilityof

the Prujecas a wholehm the Hungarianstandpoint, fur asstatedindem (v), withoiit the

5.11 There was nothing inthe Resolutionof 13 May that indicated,as

5.12 The HungarianParIiamenfar Ryesuliifiof 2 June 1989 co&ms this

This is untrue, and no evidencehas been producedby Hungaryin supportofsuch an

incorporatedintheHungarian Government'R s esolutionadoptedthatveryday. Thisis clear

evidenceoftheunilaterdcharacteo rfthesedecisions3'.

5.20 In retruspecf,the Hungarian Goverment - and now Hungary's
Mernoria i havemade an attempt toexplainawayHungwy'sunilatera icts asto Nagymaros

by clairningCzechoslovakia'sacquiescence. This is entirelycontrary to the facts;and it

indicateshow wlnerable Hungary redises itscase tu be inrespect tu Nagparos. The
CzechosIovak Governent atoncevehementlyprotestedin the most fumd way thedecisiuns

as steps taken lrniIare raIdinviolationof the 1977 ~reafl. The Hungarian Mernorial

theHungarian Govement's adoption ofa ResoIutionconfairiingthnew decisionsonthe very

Decernber 1991,the CzechosIovak Governent decided"to putthe GabEkovo part [ofthe

"open to the conclusionsofthe experts"of a ftilatercornmittee. This isclearhm the
Czechoslovak PrimeMiriister'etteraf18 DecernberI991 '49.

5.91 As Hungary's Memorial points out, this letter expressed

Czechoslovakia'sintentionto put Gabèkovo into operation- but only "to preservethe

5.103 The Resolution,whichwas not made publicat the time but which

of seriousenvironmentdriskon which Hungary publicIybase tsunilaterd decisiontu stop

7.17 The hdings of Bechtelhave already been examined inthe Slovak

7-70 According tu Appendii 3 ofHungaxy'sMemurial,a fivevearresearch
and develuriment program was carried out, starting in 7980by Budapest Waterworks

specXcallydirected at "the protectionand developmentof bank filtereddrinkingwater
res~urces"'~.The resultofthisprogram havenotbeenannexedbyHungaiy toitMemorid.

Huwever,shortextracts are provided,hm which the fulIowingtwo points areof cruciai
importance:

- &g, the Danube riverbedintheNagymaros-Budapesstector hasbeen

lowered by up tu 1.5 rn "due to theeffects ofcommercial grad
dredging (20millionm3)".Suchdredging, carri eut byHungaryand

exceeding by 3 timestheexcavationsenvisagedunderthe Project,has

7.71 With regard to Hurigary'sdredghg of this sector of the Danube,

Appendix 3 to the HungarianMemorialnow Statesthatfurîher"rivertrainingor regulation

correct, dthough thisew-found concem forthe riverbaiater layeriincontrat tu the large-

scale dredgingworks c&ed out inthe 1960s and1970s. hd it mustbe stressedthat the
dredging todatehasfarexceededthat whichwasanticipated for theconstructionofthe GM

System. It is truethattheProjectorîguiallyenvisagedthatthere shouldbe dredgingbelow
Nagymaros to the extent of6.5 millionm3 ofgrave1 fiom theDanube riverbed. But the

dredgingthat hasaIreadybeen carriedoutby Hungq - for reaçonsIargelyunconnected4th

theProject -is accordingtuthe HungarianMernorial2 ,0 millionm3'" . Ir is fur this reason
thatthe Bechtelreportnotedin 1990 that the dredgingwork "hasbeen teniiinatedsothat is

nolongerafactor"'08.

7.72 No evidence isgiven to suppor turrgary'csontention that thwater

E. The Non-Existence of "Threats" to Drinkin~ Water Was
Confirmeci by the Findinps of the 1985 Environmental Im~act
Assessmenf

7.73 Priorto Hungary's abandonmeno tf worksatNagymarosinMay 1989,

one of the mostimportantassessmentsof theProject'simpacton waterquantityandquality
was Hungary's 1985 EnvironmentaIlmpact ~ssessment"' . It may be noted that thiswas

concIuded atthe sametime asthe 1980-198 researchprogram camed out bythe Budapest

Waterworks.

7.74 Before reviewingthe Assessment'sconclusions, two points must be
made. m, the Remlution reqrriringitspreparatidso laiddown a serieofenvironmental

prerequisitesthe firsofwhichwas thatthe Project should not "imposedangeron thewater
supply of ~uda~est""~. The compilersof the Assessrnenttherefore accorded primary

importanceto the issues of drinkingwater re~ources"~. Second t.e findingsof the
Assessrnentinrelationtodnnking waterwerenotchallenged untilitwas politicallyconvenient

to do su,that isnot untii1989. The 1985 Opinionofthe HrrngarianAcademyof Sciences

may have criticisecerlainaspectsofthe ~ssessrnent"~, butitfullyacceptedthe findingsin
relationto drinkinwatersupplies.

7.75 With regardto both thewater in the aqriiferandthattaken hm the

hank-fdteredwells, the ksessment foundthatthe Projen wouldhave no negative cffcand
that the red threatto such resources was 6om wholIyunreiattdsources of background

pollution.FortheSzigetkozaquifer, apositiveimprovemeni tnthequalityof theresourcewas

Nor was sedimentation in the Dunakiliti-HnrSoeservoirseen asa prubiem. However the
threatto theaquiferfiom "communa andagriculturalp"ollutionwashighlighted.And itwas

noted thatasimilarpollutionthreaexistedforthewellsof SzentendreIsland(downstream of

"The Szigetkoz watertreasurisnot hmperedbythe1ocdsediieritationofthe

7.76 No Project-relateddeteriorationwas predicted forthe bank-filtered
wells upstreamof Nagyrnaros. Again,the threat to these wells was seen to be fiom

background pollution,a threat that would be decreasedasa direct resultof Project
operation"' :

"The research dealing &th the circumstancesofthe bank filteredwater

Finally,the41-importantBudapestsupplyweIIswereconsidered:

"TheBarrage System has no effect upon the filter layof the Budapest
Waterworksl waterresourcesatthe SzentendreIdand. The changesinthe filter

7.77 Thus,the Assessment'soverdl conclusionwas that"the[GN Project]

7.100 To dlege thatdue to the Projxt "nolonger wouId the water Ievel

Hungq consideredplans tu constructoneor twobmages at Nagymam. It was noless tme
when, later, Xungary initiatednegotiationsin relationto a joint developmentwith

Czechoslovakia,or in1958 when apreliminarydecisiontodevelopwas reached,or in1977

whentheTreaty was ~i~ned'~~.

7.127 Hungary argues that,in1980, it commenced a review of its hancial
undertakings asa resuitof"thechangingworId economy andthe deterioratingeconomic

example,in Iune1993, the DanubewaterIevelmund Nagymarosdropped to 68cm,
making cumercid navigationquite Zn the Iightof this, Hungary's

contentionthatVariant"Cu hashad an adverseeffecon navigationis nonsense. It is
Hungary'sunilateralnon-implernentatiaof the G/N Projectthat has createdthe

continuingnavigational roblemon the BratislatuBudapeststretchoftheDanube.

F. SeismicandGeoloeicalConsiderations

comprehensive evduaiionof the region'sgeoIugicaand seisrnicrisis. Not only did

Variant "C"benefitfrom the impressiveresearchdata,strrdieand explanatorydata

G. EnvironmentalProtection

Variant "CH with a review of the 19 environmentaclonditionswhich the SIovak
Commission for the Environmentdevelopedpriorto the implementationofVanant
11~76
. Hungary makesno comment asto the sufficiencyof these conditions. It is
therefure supposed that theyare accepted to be adequate prerequisitesfor the

implementationofVariant "C".

8.46 Hungarydoes not citethe conditions;it merely summarises
them in iîs Mernoriai. Referencein suppoismade tu theWWF Ausrrian Report of

January 1994,which does not cite the conditions,eithercontentsitseIfby notirig

contrary, Hungaryasserts,on the bais ofaninformationreleaseof the Slovak
Environmental Commission of Mach 1993, that asof thatdatejust 7 of the 19

conditionshadbeenfuIErI (conddition9,10, 12,14, 5, 16 and 19)7. h fa&,this

8.48 Furthemore, the same document predicts the idfilment of

conditions1,3,4 and 5befuretheend of 1993. Thus,ody 2 conditionsweredeerned

Hungary states:

the relevant provisioof the1977 Treaty were,inéffect,anUnpIementationof the

the negotiations had to involve either the furnisbg of dekitive proof by

Obligationtu Couperate

11.O4 The Hungarian Memorial advances the argument that Varian" tC"
involves theunilateraoperationof the G/N Projectand, thus, violates the joint system

estaHished under the 1977 ~reaty'. It dso asserts that th1976 Boundary Waters
Management Agreement'"laidyprohibitsunirateraioperation"af irivariousprovisions of

1 HungananMernoria,aras.7.06-7.07.thisAgreement insupportz. Hungary argues that thereievantpronsions of these freatieset

out procedures tobe foIIowed inthemanagemeno t fconimonlysharedwaters,namely, supply
of prior information, mnsultation, negotiations and joint agreement3. The relative

performance ofthe partiesisthen~mparedand ifisasseked:
l

"Hungaryhas continue upheldits due to consult and negotiate, especidy
from 1989 onward,asshow throughoutthis ~emoIial' ."

Theanaiysisof the events and evidenceinChaptersV 6d VI abovehasestabfished thetotal
faisi ofythisassertions. I
I

11.05 The HungarianMemord dso corjtendsthat, withparticularregard to

Variant "C",CzechosIovaki daidnot compfywiththetreatyobligations to couperate,citing as
1
an example: I
i
"[Czechoslovakia'su ]nwiliingnessto interrupt:the works on Variant "C"

pending a negotiatedsettlement,despire theinvitationsmadebyHungq hm
1989 onwards..'."
i

But the reference to "1989 onwards"is wholly misleàdig. Therewere no works to be
intemir>ted and oreenththenhe &vity did not affectthe flow of the

Danube.Nor wasthereprogress on anegotiatedsettlement. On 10 Januq 1990, Hungaty's

11.07 The Hungarian Mernorial'finaargument in supportof itcontention

SECTION 1. TheRe~ublicofHunearv'sView of Those Conseauences

12.02Hungary' sholeperceptioofwents isbasedupon fourpremises.

(i) Thatthe 1977 Treatywas lawfullterminateby Hungaryon 19 May
1992.

fii) That until December 1992 -thedateofCzechuslovakia'dissoIution

-anyresponabiq restedentirylwithCzechoslovakia.

(iii) ThatSlovakiawasneithera-Parttothe1977 Treaty,norasuccessoto
CzechosIuvakiain respectofany rights and obligationsunderthe
Treaq.

That,accordingly,the liabiitiesof Slovarisnot fiomthe Treaty

constructioand operationofVariant "C" - andffringarytherefure seeks rernediesagainSIovakiain!respe ocrthis quite separact of

i

12.03 It wiibe imrnediatelobviousthatHungary'sprimaryaimis to isolate

Slovakiafrom the 1977Treaty. For ifSInvakiahasneither righnor obligationsunder the
Treaty,itfoHows- atIeastiHungary' vsiew-thatSlovakiaismt entitlto chargeHurigary

with any breachof the Treaty, Iiotoju* VariantTC* as the best availabmeansof
implernentinthe Treatyintheface of afundamenta blrkh byHungary. The reasoningis

fundamentaiiyflawed. As Chapter X has demonstratedthe purportedterminationof the
Treaq byHungary was illegal,andwithout eEeonthe &hts ofCzechoslovdia. Moreover,

as ChapterD has shown,SIovakiais inlawthesuccessutu Czechosiovakiainrespectofthe
1977 Treaty,andfuiIyentitletu invokewhateverrightqdaims or remediesCzechoslovakia
