Barcelona Traction at 40: The ICJ as an Agent of Legal Development

Published online by Cambridge University Press:  22 November 2010


The article revisits the Barcelona Traction judgment of the International Court of Justice, rendered forty years ago. It evaluates the lasting influence of the Court's pronouncements on the nationality of corporations and on obligations erga omnes, and uses the case to illustrate the Court's role as an influential agent of legal development. In this respect, it identifies a number of factors that can help to explain under which circumstances judicial pronouncements are likely to shape the law.

5 H. Lauterpacht, The Development of International Law by the International Court (1958), 21. Of course, one can always claim that each application of law, each judgment, is also ‘either a step forward or a step backward in the development of the law’, as does Lachs, M., ‘Some Reflections on the Contribution of the International Court of Justice to the Development of International Law’, (1983) 10 Syracuse Journal of International Law and Commerce 239, at 241Google Scholar. How to determine whether the step is a big or a small one, and what counts as ‘forward’ and ‘backward’, remains a singularly difficult endeavour; see A. Pellet, ‘Article 38’, in A. Zimmermann et al. (eds.), The Statute of the International Court of Justice – A Commentary (2006), 677, at 789 (mn. 316 in fine).

6 The subsequent considerations focus on the Court's contentious jurisdiction. Whether the Court has greater leeway to develop international law through its advisory function is a separate matter, addressed, e.g., by Lachs, supra note 5, at 246–62; and J. A. Frowein and K. Oellers-Frahm, ‘Article 65’, in Zimmermann et al., supra note 5, 1420 (mn. 316).

7 See, e.g., Legality of the Threat or Use of Nuclear Weapons (Advisory Opinion), [1996] ICJ Rep. 226 (hereafter Nuclear Weapons), at 237, para. 18; Interpretation of Peace Treaties (Second Phase), [1950] ICJ Rep. 221, at 244 (Judge Read, Dissenting Opinion); C. G. Weeramantry, ‘The Function of the International Court of Justice in the Development of International Law’, (1997) 10 LJIL 309, at 311.

8 The most prominent example in point is Art. 3(2) of the WTO Dispute Settlement Understanding, pursuant to which ‘[r]ecommendations and rulings of the [WTO Dispute Settlement Body] cannot add to or diminish the rights and obligations provided in the covered agreements’. Within the context of international criminal law, the reliance on ‘elements of crime’ (agreed between states, and intended to ‘assist the Court in the interpretation and application’ of the law (Art. 9)) presents a variant on the same theme.

20 See, e.g., the dissenting opinion of Judge Álvarez in Competence of the General Assembly (Advisory Opinion), [1950] ICJ Rep. 4, at 13. See generally on Judge Álvarez's position on the lawmaking power of the International Court K.

24 R. Jennings and A. Watts (eds.), Oppenheim's International Law, vol. 1 (1992), 41; Boyle and Chinkin, supra note 12, at 268.

25 For details on the techniques used by international courts to influence the law see Lauterpacht, supra note 5, at 156–7; Ch. de Visscher, Theory and Reality in Public International Law, trans. P. E. Corbett (1968), 393–403; and, in more detail, Weeramantry, supra note 7, at 313–20. According to the latter (at 320) the compounding of decisions applying general rules to specific facts unavoidably leads to further elaboration and development of the law, even if only on a ‘micro scale’. Cf. H. Kelsen, Reine Rechtslehre (1960), 242 ff., who speaks of the ‘constitutive character of judicial decisions’ in general.

26 De Visscher, supra note 25, at 391. For considerations on the ‘limits of lawmaking’ see also D. Terris, C. Romano, and L. Swigart, The International Judge: An Introduction to the Men and Women Who Decide the World's Cases (2007), 127–30.

27 This is the most generous calculation, based on the number of cases inscribed on the Court's General List (146 as at May 2010), including those quickly dropped. For full details see It should be noted that even Charles de Visscher, who otherwise stressed the importance of judicial law-making, remarked that ‘[d]oubtless long years must still pass and many more judgments be rendered before the Court's decisions can be synthesized in a systematic body of principles or rules’ (supra note 25, at 403). See further Boyle and Chinkin, supra note 12, at 269.

28 In Pellet's terms, ‘the Court does not have the last word’ (supra note 5, at 790 (mn. 319)).

29 The reversal, in Art. 1 of the 1952 Brussels Collision Convention and Art. 11 of the 1958 High Seas Convention, of the Lotus ruling on the exercise of national criminal jurisdiction over persons responsible for collisions on the high seas may be the most prominent example in point. For brief comment see A. von Bogdandy and M. Rau, ‘Lotus, The’, in Wolfrum, supra note 2, at para. 20.

30 Cf. Lauterpacht, supra note 5, at 5: international tribunals as ‘agencies for the development of international law’.

31 But see the balanced considerations in Boyle and Chinkin, supra note 12, at 300–10.

32 In addition to the ‘rules of thumb’ addressed in the text, it is worth mentioning that some commentators (e.g. G. Schwarzenberger, International Law as Applied by International Courts and Tribunals, vol. 1 (1957), 31) place emphasis on the margin by which a decision has been reached: hence a pronouncement that has gained the unanimous or near-unanimous support of the bench is said to be more influential than one that divided the Court.

69 A detailed treatment can be found, for example, in the following works: A. de Hoogh, Obligations Erga Omnes and International Crimes (1996); C. J.

Sicilianos, Les réactions décentralisées á l'illicité: des contre-mesures á la légitime défense (1990); P. Picone, Comunità internazionale e obblighi ‘erga omnes’ (2006); as well as in the contributions to C. Tomuschat and J.-M. Thouvenin (eds.), The Fundamental Rules of the International Legal Order – Jus Cogens and Obligations Erga Omnes (2006). The clearest summary is J. A. Frowein, ‘Obligations Erga Omnes’, in Wolfrum, supra note 2. Ragazzi's monograph, supra note 3, contains much information on specific examples of obligations erga omnes, but curiously neglects the concept's enforcement aspect.

70 See, e.g., A. D. McNair, ‘Treaties producing effects “erga omnes”’, in Scritti di diritto internazionale in Onore di Tomaso Perassi, vol. 2 (1957), 21; and see Tams, supra note 69, at 103–6, for comment and further references.

89 The most radical extension of the erga omnes concept can be found in Judge Cançado Trindade's separate opinion appended to the Court's interim order in the Belgium v. Senegal case (supra note 81, at paras. 68–73). In the judge's view, the erga omnes concept, ‘heralding the advent of the international legal order of our times, committed to the prevalence of superior common values’ (para. 71), required a wide-ranging reinterpretation of traditional international law; notably it implied the granting of interim protection under more lenient conditions, and the horizontal application of human rights law. For brief comment see Tams, supra note 69, 312 ff. (new epilogue to the paperback edition).

90 See, e.g., van Alebeek, R., ‘The Pinochet Case: International Human Rights Law on Trial’, (2000) 71 British Year Book of International Law 29, at 34CrossRefGoogle Scholar.

91 See, e.g., Gabcikovo Nagymaros, [1997] ICJ Rep. 7, at 117–18 (Judge Weeramantry, Dissenting Opinion); R. Lefeber, ‘Editorial: Cum Grano Salis’, (1998) 11 LJIL 1, at 6–7; C. J. Tams, ‘Waiver, Acquiescence and Extinctive Prescription’, in J. Crawford, A. Pellet, and S. Olleson (eds.), The Law of International Responsibility (2010), para. 14.

92 Legal Consequences of the Construction of a Wall in the Occupied Palestinian Territory (Advisory Opinion), [2004] ICJ Rep. 136, at 200, para. 159. This may have been better explained as a consequence of the serious breach of an obligation imposed by a peremptory norm in the sense of ASR, Art. 41. For comment see S. Talmon, ‘The Duty Not to “Recognize as Lawful” a Situation Created by the Illegal Use of Force or Other Serious Breaches of a Jus Cogens Obligation: An Obligation without Real Substance?’, in Tomuschat and Thouvenin, supra note 69, at 99–125.

93 Rubin, supra note 78.

94 See Judge Higgins's pertinent observation in her separate opinion in the Wall opinion (supra note 90, at 216, para. 37 (Judge Higgins, Separate Opinion): ‘The Court's celebrated dictum in Barcelona Traction, Light and Power Company, Limited, Second Phase (Judgment, I.C.J. Reports 1970, p. 32, para. 33) is frequently invoked for more than it can bear.’

95 Terris et al., supra note 26, 129.

96 The Court determined the existence of a gap quite clearly when it stated that ‘international law had not established its own rules’ on the matter under consideration: see supra note 40.

100 De Visscher, supra note 25, 397.

101 Supra, section 1.2.

102 In contrast, the experience of the case confirms the third ‘rule of thumb’ – namely that unanimous or near-unanimous pronouncements by the Court would be more likely to influence the law. See supra note 32 for reference.

107 For further attempts to dismiss the erga omnes dictum as irrelevant because of its obiter status see F. A. Mann, ‘The Doctrine of Jus Cogens in International Law’, in Ehmke et al. (eds.), Festschrift Scheuner (1973), 399, at 418 (a dictum ‘that was unnecessary to the decision and which convey[s] the impression of having been studiously planted into the text or artificially dragged into the arena’); and similarly J. Charney, ‘Comment’, in Delbrück, supra note 78, 158 at 159.

108 It seems to be treated as such by many commentators who are prepared to accept the relevance of the erga omnes dictum, but maintain the distinction between ratio and obiter; see, e.g., Shahabuddeen, supra note 34, at 159; O. Schachter, International Law in Theory and Practice (1991), 344 (‘Although this comment . . . was pure obiter dictum, it has been widely influential’).

109 [1928] PCIJ, Ser. A, No. 17, at 47. In the circumstances of the case, Germany had only demanded compensation; see C. Gray, Remedies in International Law (1987), 96.

110 [1932] PCIJ, Ser. A/B, No. 46, at 147. This was to serve as the basis for VCLT, Art. 36; see the ILC's commentary on draft article 32, (1966) 2 Yearbook of the International Law Commission 228, para. 4.

111 [1927] PCIJ, Ser. A, No. 10, at 18. In fact, the Lotus presumption is often criticized as (among other things) having been unnecessary; see notably Lauterpacht, supra note 5, at 361.
