The International Law Commission is a subsidiary organ of the United Nations General Assembly entrusted with the progressive development of international law and its codification. This talk argues that the Commission interprets international law, as part of its function, in numerous topics of its work, and that the Commission’s interpretative activity serves its long-lasting vision to reinforce international law by providing clarity and predictability as to its content thus convincing states to continue to use international law as a medium by which they regulate their affairs. Dr. Danae Azaria is a Senior Lecturer at the Faculty of Laws at University College London (UCL). She is the author of numerous publications on public international law, including the monograph, 'Treaties on Transit of Energy via Pipelines and Countermeasures' (OUP, OMIL, 2015), which received the Paul Guggenheim Prize in Public International Law (2016). Her research interests lie in general public international law, the law of treaties, state responsibility, international economic law and the law of the sea. Her recent research focuses on the work of International Law Commission, and the Sixth Committee. She frequently advises governments, international organisations and companies on issues of public international law.
