International Law; Customary International Law; Fragmentation; International Court of Justice
Résumé :
[en] This chapter critically examines the International Court of Justice's (ICJ) role in shaping customary international law and its broader implications for the coherence of international law. It challenges the notion of the ICJ as a unifying 'high priest' of international law, instead highlighting its cautious approach to the development of customary law. The chapter critiques the widely held belief in a standardized 'rule of recognition' for identifying customary law, exploring how fragmented judicial practices and vague methodologies contribute to systemic ambiguity. Drawing on H.L.A. Hart's theories, it emphasizes the inherent challenges in aligning the ICJ's authority with a coherent, universally accepted legal framework. Additionally, it discusses the ICJ's "methodological poker face," suggesting that its cautious and often opaque approach neither strengthens its centrality nor mitigates concerns of fragmentation. The analysis concludes by exploring how states, scholars, and the International Law Commission respond to this ambiguity, often maintaining similarly guarded and cautious positions.
