Selected from the papers presented at the twenty-third International Social Philosophy Conference held in July of 2006 at University of Victoria in Victoria, British Columbia --Preface.

The International Law Commission was established in 1947 with a view to carrying out the responsibility of the General Assembly, under article 13(1)(a) of the Charter of the United Nations, to “initiate studies and make recommendations for the purpose of ... encouraging the progressive development of international law and its codification.” Since its first session in 1949, the Commission has considered a wide-range of topics of international law and made a number of proposals for its codification and progressive development, some of which have served as the basis for the subsequent adoption of major multilateral treaties. The Yearbook of the International Law Commission contains the official records of the Commission and is an indispensable tool for the preservation of the legislative history of the documents emanating from the Commission, as well as for the teaching, study, dissemination and wider appreciation of the efforts undertaken by the Commission in the progressive development of international law and its codification. Volume II (Part One) reproduces the edited versions of the official documents considered by the Commission at the respective annual session.

This publication contains the texts of the papers presented at the UN Colloquium, together with a record of those presentations and of the discussions which took place around them.

In December 2011, the United Nations General Assembly adopted the International Law Commission's articles on the responsibility of international organizations, bringing to conclusion not only nearly ten years of reflection by the Commission, governments and organizations on this specific topic, but also decades of study of the wider subject of international responsibility, which had initially focused on State responsibility. Parallel to this reflection by the Commission, diplomats and public officials, the body of international case-law and literature on the many facets of the topic has steadily been growing. Responsibility of International Organizations: Essays in Memory of Sir Ian Brownlie contributes to the body of international literature by collecting a broad spectrum of different and sometimes differing perspectives from well-known experts in the field, ranging from the bench to the Commission, academia, and the world of in-house counsel. The book is also a memorial to the renowned Sir Ian Brownlie, himself a former Chairman of the International Law Commission who, as a leading scholar and practitioner, greatly contributed to the reflection on international responsibility, including the responsibility of international organizations. Edited by Maurizio Ragazzi, a former pupil of Sir Ian, the book is an ideal companion to International Responsibility Today, a collection of essays on international responsibility which the same editor presented in 2005 in memory of Oscar Schachter, and to which Sir Ian Brownlie had contributed. The essays collected in Responsibility of International Organizations: Essays in Memory of Sir Ian Brownlie, conveniently grouped by the editor under broad areas for the reader's benefit, will be relevant not only to all those interested in this specific subject but also, more generally, to all those engaged in the field of international law and the law of international organizations.

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.

The Charter of the United Nations was signed in 1945 by 51 countries representing all continents, paving the way for the creation of the United Nations on 24 October 1945. The Statute of the International Court of Justice forms part of the Charter. The aim of the Charter is to save humanity from war; to reaffirm human rights and the dignity and worth of the human person; to proclaim the equal rights of men and women and of nations large and small; and to promote the prosperity of all humankind. The Charter is the foundation of international peace and security.
