Law And Treaty Series

Revised and updated, this handbook by the Treaty Section of the United Nations Office of Legal Affairs is intended as a contribution to UN efforts to assist States in becoming parties to the international treaty framework. It is written in simple language and, with the aid of diagrams and step-by-step instructions, touches upon many aspects of treaty law and practice. This handbook is designed for use by States, international organizations and other relevant entities. In particular, it is intended to provide some degree of assistance to States that may have scarce resources and limited technical proficiency in treaty law and practice to participate fully in the multilateral treaty framework.

The author successively discusses: I) The scope of the Convention and its relationship to customary law; II) The conclusion and entry into force of treaties; III) The application, interpretation, amendment and modification of treaties; IV) The invalidity, termination and suspension of operation of treaties; V) Jus cogens and the settlement of disputes.

The centrality of treaties to the international legal system requires little emphasis. Not only is the treaty a source of law that the International Court of Justice (ICJ) is bound to apply when resolving international disputes, but it is also the medium through which the vast preponderance of international legal intercourse is now conducted. The essays contained in this informative volume disclose a wide variety of opinion on a broad range of issues concerning the conclusion, application and termination of treaties.

The United Nations is a vital part of the international order. Yet this book argues that the greatest contribution of the UN is not what it has achieved (improvements in health and economic development, for example) or avoided (global war, say, or the use of weapons of mass destruction). It is, instead, the process through which the UN has transformed the structure of international law to expand the range and depth of subjects covered by treaties. This handbook offers the first sustained analysis of the UN as a forum in which and an institution through which treaties are negotiated and implemented. Chapters are written by authors from different fields, including academics and practitioners; lawyers and specialists from other social sciences (international relations, history, and science); professionals with an established reputation in the field; younger researchers and diplomats involved in the negotiation of multilateral treaties; and scholars with a broader view on the issues involved. The volume thus provides unique insights into UN treaty-making. Through the thematic and technical parts, it also offers a lens through which to view challenges lying ahead and the possibilities and limitations of this understudied aspect of international law and relations.

The book explores the various means of making non-conventional/non-treaty law and the cross-cutting issues that they raise. Law-making by technical/informal expert bodies, Conferences of Parties, international organizations, the UN Security Council, regional organizations and arrangements and non-state actors is examined in turn. This forms the basis for the analysis of the complementarity of international treaty law, customary international law and non-traditional law-making, potential subject matters of non-treaty law-making, domestic consequences of non-treaty law-making, proliferation of actors, commissions and treaty bodies of the UN system, and International courts and tribunals.

On the publication of its first edition, this textbook was welcomed as the definitive study of treaty law written from the viewpoint of an experienced practitioner. As with the first, this edition aims to provide the student and practitioner with a full understanding of the law and updates existing information and refines previous arguments. New to its scope of examination is the study of the use of memorandums of understanding (MOUs) in litigation, the treaty-making capacity of entities such as the Vatican, Taiwan and Palestine, and the effect of hostilities on treaties. Given their increasing importance, there is also a new chapter on international organisations, including an attempt to explain the sometimes baffling roles in treaty-making played by the European Community and European Union. Students and practitioners alike will find this an invaluable guide to this increasingly important subject.
