Annexed to GA Resolution 56/​83 of 2001, the International Law Commission's Articles on Responsibility for Internationally Wrongful Acts put the international law of responsibility on a sound footing. As Special Rapporteur for the second reading, James Crawford helped steer it to a successful conclusion. With this book, he provides a detailed analysis of the general law of international responsibility and the place of state responsibility in particular within that framework. It serves as a companion to The International Law Commission's Articles on State Responsibility: Introduction, Text and Commentaries (Cambridge University Press, 2002) and is essential reading for scholars and practitioners concerned with issues of international responsibility, whether they arise in interstate relations, in the context of arbitration or litigation, or in bringing international claims.
