This article challenges the argument that the World Trade Organization (WTO) is devoid of executive or governing functions and, hence, immune from the regime set out in the International Law Commission’s 2011 Draft Articles on the Responsibility of International Organizations (RIO). A brief drafting history of the RIO, clarification of the terminology associated with matters of international responsibility, and two hypothetical examples illustrating the potential for WTO responsibility set the stage for the article’s main argument. The author examines the WTO’s nature by analyzing its constituent law, its sui generis mandate and functions, its international legal personality, and its own use of terminology in presenting itself to the world. Critical analysis of RIO Articles 64 (on lex specialis) and 10 (on the existence of a breach of an international obligation), and their application to the WTO, completes the argument. The author thus refutes both the notions that (1) the WTO is exclusively member driven and, hence, not an executive, governing organization but a sui generis entity and (2) the WTO is therefore unable to breach an international obligation and thus immune from the RIO regime. The article concludes that, while a breach by the WTO of an international obligation may be exceedingly rare, it nonetheless — as any international organization — comes within the ambit of the RIO regime. The WTO should therefore consider adjusting its internal rules accordingly.
