On 30 May 2016, the International Law Commission (‘ILC’) adopted a set of 16 Draft Conclusions providing a methodology on how to identify customary international law. Although largely based on the two elements approach set forth in article 38(1)(b) of the Statute of the International Court of Justice, the ILC study pushes the boundaries of the formal sources of international law beyond the realm of state practice by recognising that the practice of international organizations (‘IOs’) as such may be constitutive of custom. This article critically examines the ILC Draft Conclusions concerning the role of IOs in the process of custom creation. It examines the concept of resolution adopted by the ILC and assesses the coherence of the interpretive methodology devised by the ILC using the UN General Assembly resolutions as a case study. The findings show that the Draft Conclusions fall short of expectation in providing authoritative guidance to scholars and practitioners alike.

评估决议在国际法委员会关于习惯国际法识别的结论草案中的作用

2016 年 5 月 30 日，国际法委员会（“ILC”）通过了一套 16 项结论草案，提供了如何识别习惯国际法的方法。尽管主要基于《国际法院规约》第 38(1)(b)条规定的两个要素方法，但国际法委员会的研究通过承认国际法的正式渊源的界限超越了国家实践领域国际组织 ('IOs') 的做法本身可能构成习惯。本文批判性地审查了关于 IO 在自定义创建过程中的作用的 ILC 结论草案。它审查了国际法委员会通过的决议概念，并以联合国大会决议为案例研究评估了国际法委员会设计的解释方法的一致性。
