The Rhetoric of Fragmentation: Fear and Faith in International Law

  • ANNE-CHARLOTTE MARTINEAU
Abstract

Over the last decade international lawyers have been increasingly concerned with the ‘fragmentation’ of international law. However, given that this expression has been repeatedly used by the profession since the mid-nineteenth century to depict the state of international law, one may wonder about its recent revival in the international legal discourse. Why has it re-emerged? What can we learn from previous invocations? An answer may be sought by contextualizing the fragmentation debate in a historical perspective. This brings out the repetitive and relatively stylized modes in which the profession has narrated legal developments. This essay suggests a correlation between periods of crisis in general and a critical view of fragmentation on the one hand, and periods of scholarly enthusiasm and the prevalence of positive views about fragmentation on the other. This analysis sheds critical light on both the implicit assumptions and political implications of the current debate on fragmentation.

7 Although his analysis focuses on scholars in the United States, it can very well be expanded to include Continental doctrine, given the dynamics of production and the reception of international legal thinking. Accordingly, the last half of the nineteenth century saw a self-confident period of invention and renewal among international lawyers, which took place from roughly 1871 to the First World War. It was followed by a period of confusion and rethinking, which lasted from 1914 to the mid-1920s. This phase was replaced by another period of confidence and consolidation which persisted until the outbreak of the Second World War. But again, the war initiated a period of confusion and rethinking which continued through the early Cold War years. In the 1960s a period of self-confident renewal succeeded, repeating much of the previous enthusiastic periods. It lasted until the end of the Cold War, which gave rise to the current period of confusion and rethinking.

The notion of functional differentiation has been developed notably by Niklas Luhmann to explain the evolution of late modern societies. For his view on law, see Law as a Social System (2004). Andreas Fischer-Lescano and Gunther Teubner were among the first to transpose this conceptual framework to international law. See their article ‘Regime-Collisions: The Vain Search for Legal Unity in the Fragmentation of Global Law’, (2004) 25 Michigan Journal of International Law 999.

9 As is often the case with words with the same suffix, fragmenta-tion refers both to a result (international law is fragmented) and to a process (it is fragmenting). The two meanings are mutually exclusive: if the law is fragmented or primitive, then it cannot be disintegrating (we assume that it is already so); if the law is disintegrating, then it cannot yet be fragmented (we fear that it might become so). See more generally R. Guastini, Estudios sobre la interpretación jurídica (2003), at 71.

17 ‘The disunity of the modern world is a fact, but so, in a truer sense, is its unity. Th[e] essential and manifold solidarity, coupled with the necessity of securing the rule of law and the elimination of war, constitutes a harmony of interests which has a basis more real and tangible than the illusions of the sentimentalist or the hypocrisy of those satisfied with the existing status quo’.

21 We cannot simply ask whether international law forms a system, because our response depends precisely on how we have defined the ‘system’. M. Troper, Pour une théorie juridique de l'Etat (1994).

22 This draws on the suggestion that the systematization of international law has two advantages, namely to promote legal (and not political) relations between states and to ensure the primacy of international (and not national) law. See Kennedy, ‘When Renewal Repeats’, supra note 7; J.-L.

36 However much this sense could be criticized by both the ‘idealist’ and ‘realist’ positions. Kennedy has shown how narratives about the origin of international institutions rest on an ambivalent vision of war, of peace, and of the process by which war gives way to peace. See Kennedy, ‘Move to Institutions’, supra note 7, at 845.

47 This primacy was the result of a political choice for Kelsen, whereas it was presented by Scelle as a natural consequence of the unity of social reality. See H. Kelsen, ‘Les rapports de système entre le droit interne et le droit international public’, (1926-IV) 14 RCADI 233; G. Scelle, Précis de droit des gens (1932–4), 349–64.

48 For Kelsen, ‘norms of general international law are inferior in terms of number and importance as compared to local norms [including] norms of particular international law’. Kelsen, H., Théorie générale du droit et de l'Etat (1997) 327, at 374. Even the solidarist Scelle acknowledged the existence of ‘particular international legal orders’, since these orders were ‘conditioned and absorbed by larger international legal orders (international regionalism), these larger orders being themselves part of the global international legal order’. G. Scelle, ‘Règles générales du droit de la paix’, (1933-IV) 46 RCADI 327, at 343.

53 He claimed to be breaking with ‘the traditional conception of the universality of legal rules’ that he now labelled ‘formalism’. In the 1930s he did not speak of a ‘civilizing mission’ that belonged to Latin America (as he did previously). See, e.g., his La codification du droit international, ses tendances, ses bases (1912).

58 Le Fur, L., Précis de droit international public (1933), at 303.

59 Le Fur's anxiety echoed that of his contemporaries such as Paul Valéry, who depicted France in 1932 as subject to ‘a number of incompatible forces, none of which [could] either win or lose. Never [had] humanity linked so much power with so much disarray, so much anxiety with so many playthings, so much knowledge with so much uncertainty’. For a thorough analysis see E. Weber, The Hollow Years: France in the 1930s (1995). In art, the post-1914 disillusion and sense of chaos were forcefully expressed by Dadaism, using primitivism to represent the fractured world. See C. Sweeney, From Fetish to Subject: Race, Modernism, and Primitivism, 1919–1935 (2004).

60 In the face of Álvarez's strong definition of regionalism, Le Fur's response is marked by a mixture of desire and terror (the latter being prominent) similar to the field's attitude towards nationalism in the inter-war period. See Berman, N., ‘“But the Alternative Is Despair”: European Nationalism and the Modernist Renewal of International Law’, (1993) 106 Harvard Law Review 1792.

66 Ibid., at 493.

67 There were some, however, like Joseph Barthélemy, who criticized the field's ‘excesses in abstract legalism’ and its tendency to prefer uniform or general rules over the ‘reality’. Nevertheless, these denunciations seem to have remained in the background. J. Barthélemy, ‘Politique intérieure et droit international’, (1937-I) 59 RCADI 421, at 442.

68 Redslob, R., Les principes du droit des gens moderne (1937), 19. This idea was also expressed by Fauchille, supra note 57, at 301.

69 At that time, narratives about the League tended to differentiate its early days from its later days, considering the League to be successful until emasculated by power politics. See Kennedy, ‘Move to Institutions’, supra note 7, at 876–7.

73 Hence, the ICJ is as commonly described as the PCIJ's successor, whereas the PCIJ was thought to be related to the Hague system but not to have succeeded it. See Kennedy, ‘Move to Institutions’, supra note 7.

93 Kelsen's outright rejection of legal gaps was based on the presumption of states’ residual liberty. Any dispute could be resolved by international law if state parties so desired. H. Kelsen, ‘Théorie du droit international public’, (1953-III) 84 RCADI 175.

94 Lauterpacht refuted the distinction between legal and political disputes, considering the legal system to be materially (and not formally) complete. International judges could always resort to contextual standards or other considerations to resolve a case. Because he believed (his) judicial practice to be a privileged instrument for order and justice, he argued that the law's unity would be ensured not so much by UN administrative bodies as by the judicial profession. H. Lauterpacht, ‘Some Observations on the Prohibition of “Non Liquet” and the Completeness of the Law’, in Symbolae Verzijl (1958), 196. He had already formulated this argument in The Function of Law in the International Community (1933), 245–345.

107 Launched in the 1970s, the NIEO represented ‘the culmination of a decade-long process of attempting to articulate an alternative to the mainstream approach to the international economic system’. Mickelson, K., ‘Rhetoric and Rage: Third World Voices in International Legal Discourse’, (1998) 16 Wisconsin International Law Journal 353, at 365.

108 See, e.g., Chimni, C., International Law and World Order: A Critique of Contemporary Approaches (1993), 9.

109 Each had their domain: coexistence between the First and Second Worlds, co-operation in the Third; coexistence for peace and security, co-operation for development and economy, etc. Kennedy, D., ‘The “Rule of Law”, Political Choices, and Development Common Sense’, in Trubek, D. and Santos, A. (eds.), The New Law and Economic Development: A Critical Appraisal (2006), 120.

110 Anand, R. P., ‘Development and Environment: The Case of the Developing Countries’, (1980) 24 Indian Journal of International Law 1.

111 There were obviously disagreements regarding the appropriate strategy; Third World proponents debated whether the problem was inequality of bargaining power or a more profound structural bias, whether procedural solutions were adequate or not, and so on. Nevertheless, in broad terms the NIEO programme was a compromise between moderate and radical visions – and it was understood as such by both proponents and opponents.

112 In the 1970s the ‘basic needs’ strategy was endorsed by the World Bank, the ILO and other agencies. See, e.g., Report of the Director General of the ILO, Employment and Basic Needs: A One-World Problem (1976).

113 C. Fenwick, ‘International Law: The Old and the New’, (1966) 60 AJIL 475, at 481.

114 Another example is the law of development promoted by René-Jean Dupuy, whose ‘situational logic’ differed from the ‘universal logic’ of traditional international law. Traditionally, he explained, international law did not prescribe derogative rules for Third World countries, although their situation often required it. By contrast, development law was premised on the idea that unequal situations required different treatments, and this could only be done through ‘individualized, differentiated and concrete rules’.

120 At the 1977 annual meeting, he introduced his talk on the ‘impact of complex regional systems on the overarching structure’ by stating that ‘every regional system leads to the fractionalizing of the international legal order’. Thus the question was not whether fragmentation was formally possible but whether ‘it served or hindered the progress of international law’. This question could not be answered in the abstract because it depended on state practice: what would they privilege and to what ends? States could very often justify their actions on the basis of both universal law and regional law. L. Dubouis, ‘Les rapports du droit régional et du droit universel’, in Société Française pour le Droit International (SFDI), Régionalisme et universalisme dans le droit international contemporain (1977).
