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.

The political changes in the world have profoundly altered the United Nations. This new book is one of the first to describe the structure of the world organization in the present context of international relations. "The United Nations: Law and Practice" is a no-nonsense book, concise, informative and up-to-date. In their respective careers as diplomats or academics, all authors combine vast practical and theoretical experience in dealing with the UN.

This is a study of the principal negotiating processes and law-making tools through which contemporary international law is made. It does not seek to give an account of the traditional - and untraditional - sources and theories of international law, but rather to identify the processes, participants and instruments employed in the making of international law. It accordingly examines some of the mechanisms and procedures whereby new rules of law are created or old rules are amended or abrogated. It concentrates on the UN, other international organisations, diplomatic conferences, codification bodies, NGOs, and courts. Every society perceives the need to differentiate between its legal norms and other norms controlling social, economic and political behaviour. But unlike domestic legal systems where this distinction is typically determined by constitutional provisions, the decentralised nature of the international legal system makes this a complex and contested issue. Moreover, contemporary international law is often the product of a subtle and evolving interplay of law-making instruments, both binding and non-binding, and of customary law and general principles. Only in this broader context can the significance of so-called 'soft law' and multilateral treaties be fully appreciated. An important question posed by any examination of international law-making structures is the extent to which we can or should make judgments about their legitimacy and coherence, and if so in what terms. Put simply, a law-making process perceived to be illegitimate or incoherent is more likely to be an ineffective process. From this perspective, the assumption of law-making power by the UN Security Council offers unique advantages of speed and universality, but it also poses a particular challenge to the development of a more open and participatory process observable in other international law-making bodies.

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.
