International courts and tribunals have played a predominant role in the development of the law of maritime delimitation.1 In fact, since the North Sea Continental Shelf cases of 1969, eleven judgments concerning maritime delimitations were given by international courts and tribunals. Owing to the richness of international decisions, one may currently speak of ‘case law’ in the field of maritime delimitations. Thus it is indispensable to consider the evolving process of the law of maritime delimitation on the basis of the practice of international courts and tribunals.
1 Many writers emphasized the importance of case law in this field.Weil, PPerspective du droit de la déelimitation maritime (ParisPedone 1988) 13.Google ScholarSee also Cahier, P ‘Les sources du droit relatif àa la déelimitation du plateau continental’, in Le droit international au service de la paix, de la justice et du déeveloppement, Méelanges Michel Virally (ParisPedone 1991) 175–82;Google ScholarJennings, RY ‘What Is International Law and How Do We Tell It When We See It?’ (1981) 37 ASDI 68;Google ScholarLucchini, L and Vœoelckel Droit de la mer, M, t. 2, Déelimitation (ParisPedone 1996) 200;Google ScholarChurchill, RR and Lowe, AVThe Law of the Sea (3rd ednManchesterMUP 1999) 185.Google Scholar Yet this does not mean that State practice is meaningless in the field of maritime delimitations. There is a rich State practice on this domain, and the analysis of that practice is highly important. For State practice relating to maritime delimitations, see Charney, JI et al. International Maritime Boundaries 4 vols (Nijhoff 1993, 1998, 2002).Google Scholar With respect to a comparative analysis between the case law and State practice, see Tanaka, Y Predictability and Flexibility in the Law of Maritime Delimitation, Thesis (GenevaIUHEI 2002).Google Scholar

17 Judgment op cit n 2, 133, para 285. Nigeria has claimed 30 nautical miles territorial sea while Cameroon claimed that of 50 nautical miles. According to Cameroon, however, these claims were withdrawn when the UN Convention on the Law of the Sea entered into force. Cameroon stated that the two States have acceptedterritorial seas of 12 nautical miles since 1975. Memorial of Cameroon, 535, paras 5.79–5.80. Furthermore, Professor Pellet, Counsel of Cameroon, indicated the fact that the ‘assemblee nationale’ of Cameroon adopted law No 2000/2 in 17 Apr 2000, and Art 4 of the law fixed the breath of its territorial sea at 12 nautical miles.

53 Obviously, that dilemma arises in international law as well. In this connection, Charles de Visscher states that: ‘L'éevolution du droit international contemporain est marquéee par deux orientations opposéees. Un besoin de certitude du droit et de séecuritée travaille, depuis un sièecle, àa un developpment technique trèes poussée des regies du droit positif. Un besoin, plus réecemment ressenti, d'assouplissement de la rèegie, face àa des situations nouvelles et de plus en plus individualisees, porte àa rechercher dans les voies de l'éequite une justice adaptéee au cas concret, aux particularites de l'espèece.’ It appears that this view also points to a similar dilemma between the predictability and flexibility. de Visscher, CDe l'éequite dans le reglement arbitral ou judiciaire des litiges de droit international public (ParisPedone 1972) preface, i.Google Scholar

78 Some consider the North Sea Continental Shelf cases of 1969 as an expression of corrective equity. See, for instance, the Dissenting Opinion of Judge Evensen in the Tunisia/Libya case, ICJ Reports, 1982, 292, para 12; M Bedjaoui ‘L'“éenigme” des “principes éequitables” dans le droit des delimitations maritimes’ (1990) 62 Revista Españnola de derecho internacional 370 and 378; Weil, op cit n 1, 205–6. In contrast, Judge Jiméenez de Arechaga rejected such an interpretation of the 1969 judgment. Separate Opinion of Judge Jiméenez de Aréechaga in the Tunisia/Libya case, ICJ Reports (1982) 104, para 15. In the same vein, B Kwiatkowska ‘The I.C.J. Doctrine of Equitable Principles Applicable to Maritime Boundary Delimitation and Its Impact on the International Law of the Sea’, in Bloed, A and van Dijk, P (eds) Forty Years International Court of Justice: Jurisdiction, Equity and Equality (UtrechtEuropa Institute 1988) 134–5.Google ScholarIt is difficult to assert that the ICJ, in that case, adopted the corrective equity approach, since the North Sea Continental Shelf judgment accepted neither the mandatory character of the equidistance method nor its application in specific cases.Google Scholar
79 In addition, even in the North Sea Continental Shelf judgment, which rejected the customary law character of the equidistance method, the Court had accepted the validity of the latter in the case of opposite coasts from the viewpoints of natural prolongation: ‘The continental shelf area off, and dividing, opposite States, can be claimed by each of them to be a natural prolongation of its territory. These prolongations meet and overlap, and can therefore only be delimited by means of a median line’, ICJ Reports (1969) 36, para 57.Google Scholar
80 In the Pierre, St and Miquelon, case, it was debatable whether the relationship of relevant coasts was opposite or adjacent. On this point, the Court of Arbitration held that the overall relationship was one of adjacency: the St Pierre and Miquelon case op cit, n 67, 1162, para 35.Google Scholar
81 In particular, this confrontation was clearly demonstrated by the two contrasting proposals made in Negotiating Group 7 (NG7) during the seventh session in 1978. One was based on equidistance as a general rule, and was presented by twenty States: ‘ l. The delimitation of the exclusive Economic Zone/Continental Shelf between adjacent or opposite States shall be effected by agreement employing, as a general principle, the median or equidistance line, taking into account any special circumstance where this is justified’, UN Doc NG 7/2, 20 Apr 1978, Platzoder, RThird United Nations Conference on the Law of the Sea: Documents, vol IX (New YorkOceana 1986) 392–3.Google Scholar The other proposal relied on agreements concluded in accordance with equitable principles, and it was supported by twenty-seven States: ‘ l. The delimitation of the exclusive economic zone between adjacent or/and opposite States shall be effected by agreement, in accordance with equitable principles taking into account all relevant circumstances and employing any methods, where appropriate, to lead to an equitable solution’, UN Doc NG 7/10, 1 May 1978, ibid 402. For the analysis of the legislative history of these provisions, see in particular, Nandan, SN and Rosenne, S (eds) United Nations Convention on the Law of the Sea, 1982, A Commentary (Centre for Oceans Law and Policy, University of Virginia School of Law), vol II (DordrechtNijhoff 1993) 796–816; 948–85;Google ScholarCaflisch, L ‘Les zones maritimes sous juridiction nationale, leurs limites et leur delimitation’, in Bardonnet, D and Virally, M (eds) Le nouveau droit international de la mer (ParisPedone 1983) 92–6.Google Scholar
82 On this point, it should be noted that the confrontation between two groups was linked to another hard-core issue of peaceful settlement of disputes. The supporters of ‘equidistance’ were, as part of the package, in favour of establishing a compulsory, third-party system for the settlement of delimitation disputes. By contrast, the supporters of 'equitable principles' have generally rejected the idea of a compulsory judicial procedures.Adede, AOThe System for Settlement of Disputes under the United Nations Convention on the Law of the Sea (DordrechtNijhoff 1987) 182;Google ScholarIrwin, PC ‘Settlement of Maritime Boundary Dispute: An Analysis of the Law of the Sea Negotiations’ (1980) 8 ODIL 110.CrossRefGoogle Scholar

86 In fact, Judge Gros, in the Gulf of Maine case, called these provisions ‘an empty formula.’ Dissenting Opinion of Judge Gros, ICJ Reports (1984) 365, para 8. Furthermore, the Court of Arbitration in the Eritrea/Yemen arbitration stated that Arts 74 and 83 ‘were consciously designed to decide as little as possible.’ <http://www.pca-cpa.org/ERYE2chap5.htm>, para 116. See also Caflisch ‘The Delimitation of Marine Spaces between States with Opposite or Adjacent Coasts’, in Dupuy, R-J and Vignes, D (eds) A Handbook on the New Law of the Sea (DordrechtNijhoff 1991) 480.Google Scholar
87 It should be noted that the Arbitral Tribunal, in the Eritrea/Yemen arbitration (second phase), ruled that: ‘It is generally accepted view, as is evidenced in both the writings of commentators and in the jurisprudence, that between coasts that are opposite to each other the median or equidistance line normally provides an equitable boundary in accordance with the requirements of the Convention, and in particular those of its Arts 74 and 83 which respectively provide for the equitable delimitation of the EEZ and of the continental shelf between States with opposite or adjacent coasts.' The Eritrea/Yemen case (second phase) <http://www.pca-cpa.org/ERYE2chap5.htm>, para 131. It is suggested that the Tribunal of Arbitration considered that, so far as the maritime delimitation between States with opposite coasts is concerned, an equidistance line would provide an equitable maritime boundary under Arts 74 and 83 of the UN Convention on the Law of the Sea.

89 At the same time, it should be recalled that, as early as 1977, the Court of Arbitration in the Anglo-French Continental Shelf case held that the combined rule of ‘equidistance-special circumstances’ reflected the customary law of equitable principles, without distinguishing delimitation between opposite or adjacent coasts.Google Scholar

91 The delimitation of the contiguous zone was not at issue in the case law regarding maritime delimitations. Nor was it mentioned in the UN Convention text and, consequently, the rule applicable to the contiguous zone remains unclear. According to Caflisch, the possible solutions are: (1) to apply, by analogy, either Art 15 or Arts 74/83 of the UN Convention; (2) to resort to the equidistance method of Art 24 (3) of the Convention on the Territorial Sea and the Contiguous Zone; (3) allow for the joint exercise of the attributions provided for in Art 33 by the State concerned. Caflisch op cit n 86, 442–5. In the light of the close link between the contiguous zone and the territorial sea, Vukas favours the application of rule of territorial sea delimitation prescribed in Art 15 of the UN Convention on the Law of the Sea.Vukas, B ‘The LOS Convention and Sea Boundary Delimitation’, in Vukas, B (ed) Essays on the New Law of the Sea (ZagrebSveucilisnanaklada Liber 1985) 163–4.Google Scholar On the other hand, Symonides advocates the application of Art 74 of the UN Convention where the economic zone and the contiguous zone are to be delimited.

95 On this point, the argument of Malta in the Libya/Malta case is worth noting. In its Counter-Memorial, Malta mentioned that ‘an excessive individualisation of the rule of law, which changes from one case to another, would be incompatible with the very concept of law. Every legal rule presupposes a minimum of generality. A rule which is elaborated on a case by case basis rests on the discretionary power of the judge, on conciliation, on distributive justice—in brief, on ex aequo et bono.’ The Libya/Malta case, Pleadings, vol II, p 293, para 111. Furthermore, in the article published in 1976, Akehurst stated that: ‘Although it is desirable that rules of law should be just, it is perhaps even more desirable that they should be certain, clear and predictable’,Akehurst, ‘Equity and General Principles of Law’ (1976) 25 ICLQ 809.CrossRefGoogle Scholar

97 Bedjaoui expressly states that: ‘Us [les principes equitables] ne constituent pas une forme d'equite autonome, independante de la regie de droit et substituable a celle-ci, mais bien une equite correctrice intervenant de maniere endogene pour eviter que la regie de droit n'aboutisse a un resultat inequitable dans son application a un cas concret', Bedjaoui op cit, n 78, 384. More generally, Charles De Visscher considered the function of equity as corrective and supplementary. He mentioned that: ‘[l]a fonction de l'equite apprait tantot comme correctrice, tantot comme suppletive de la regie de droit. Correctrice, elle peut se limiter a une attitude general e d'application du droit positif dans un esprit liberal. Suppletive, elle remplit dans des cas individuels la fonction de completer la reglementation positive’, De Visscher op cit, n 53, 5–6.Google Scholar

Lucchini and Voelckel take the same viewby saying that: ‘[l]e titre est, en effet, l'element fondamental de base. La delimitation ne peut avoirlieu qu'a partir de lui et en s'appuyant sur lui.’ Op cit, n 1, 211.Google Scholar

119 The Court's view is not necessarily a new one. Some members of the Court had alreadyexpressed the similar opinion. For instance, Judge Jennings stated in the Libya/Malta case of 1984that: ‘[T]he slightest acquaintance with the jurisprudence of this Court shows that Art 59 does byno manner of means exclude the force of persuasive precedent. So the idea that Art 59 is protec-tive of third States’ interests in this sense at least is illusory’, Dissenting Opinion of JudgeJennings, ICJ Reports (1984) 157, para 27. See also 158–60, paras 28–34. In the same case, JudgeOda also stated that: ‘I would simply say that what the Court states regarding Art 59 does notlessen the concern of the third State, particularly where a right erga omnes is at issue between theoriginal litigants’, Dissenting Opinion of Judge Oda, ibid 94, para 9.
