This is the official report of the International Law Commission to the General Assembly on its seventy-third session dated 18 April-3 June and 4 July-5 August 2022.

Peremptory Norms of General International Law (Jus Cogens): Disquisitions and Dispositions is a collection of contributions on various aspects of jus cogens in international law.

Seventy Years of the International Law Commission: Drawing a Balance for the Future brings together voices from academia and practice to celebrate and critically evaluate the work of the United Nations International Law Commission (ILC) over the past seventy years. The edited volume draws on the events commemorating the seventieth anniversary of the Commission, which took place in New York and Geneva in May and July 2018. At a time when multilateral law-making has become increasingly challenging, the edited volume appraises the role of one the most important driving forces behind the codification of international law and discusses the ILC’s future contribution to the development of international law.

This volume contains a consolidated reproduction of Part One (articles 1 to 35) of the Draft Article on State Responsibility and their important Commentaries, prepared by the International Law Commission in the period ending in 1980. These articles deal with the origin of international responsibility, including general principles, the act of State, breach of an international obligation, and circumstances precluding wrongfulness. They were drawn up on the basis of eight reports submitted by the Special Rapporteur, Professor, now Judge Roberto Ago. An introduction written by Shabtai Rosenne traces the history of the official codification of the topic of State Responsibility since the League of Nations first broached the matter in 1924. State Responsibility is central to the daily practice of international law, and its systematic treatment is central to the codification process. The International Law Commission is continuing work on the topic. In the meantime, the articles of Part One, now concentrated for the first time in a single volume, are the major starting point for this work. This volume will be of great value to practitioners, teachers and students of international law. Shabtai Rosenne was a member of the International Law Commission from 1962 to 1971, when the basic decisions regarding the approach to the current phase of the work were taken.
