The ILC Articles on State Responsibility: The Paradoxical Relationship Between Form and Authority

Abstract

The adoption by the International Law Commission (ILC) in 2001 of its articles on state responsibility is an achievement that presents a paradox. This essay is about the form and authority of the articles, and the paradox that they could have more influence as an ILC text than as a multilateral treaty. The essay addresses the questions of the appropriate authority to be given an ILC text, why undue influence may be attributed to an ILC text (particularly by arbitral tribunals), and how an arbitral tribunal should approach interpreting and applying the articles on state responsibility.
