Customary International Humanitarian Law, Volume I: Rules is a comprehensive analysis of the customary rules of international humanitarian law applicable in international and non-international armed conflicts. In the absence of ratifications of important treaties in this area, this is clearly a publication of major importance, carried out at the express request of the international community. In so doing, this study identifies the common core of international humanitarian law binding on all parties to all armed conflicts. Comment Don:RWI.

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.

International law holds a paradoxical position with territory. Most rules of international law are traditionally based on the notion of State territory, and territoriality still significantly shapes our contemporary legal system. At the same time, new developments have challenged territory as the main organising principle in international relations. Three trends in particular have affected the role of territoriality in international law: the move towards functional regimes, the rise of cosmopolitan projects claiming to transgress state boundaries, and the development of technologies resulting in the need to address intangible, non-territorial, phenomena. Yet, notwithstanding some profound changes, it remains impossible to think of international law without a territorial locus. If international law is undergoing changes, this implies a reconfiguration of territory, but not a move beyond it. The Netherlands Yearbook of International Law was first published in 1970. It offers a forum for the publication of scholarly articles of a conceptual nature in a varying thematic area of public international law.

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 I reproduces the summary records of the Commission's annual sessions.

This second volume of the AIIB Yearbook of International Law examines the role of international organizations in promoting effective dispute resolution. It is divided into five parts to reflect a series of overarching themes and relationships. Firstly, international arbitration’s effectiveness and affinity with multilateral institutions. Second, international organizations as proponents of the norms of dispute resolution. Third, the dispute resolution mandates of international organizations. Fourth, the role of dispute resolution and economic development. Together, this diversity of perspectives offers convincing evidence that effective dispute resolution is a precondition to successful economic development—and that international organizations have an essential role to play in promoting both. The fifth part presents the 2018 AIIB Law Lecture given by Georg Nolte, Chair of the International Law Commission, on the subject of ‘International Organizations in the Recent Work of the International Law Commission’ and the 2018 AIIB Legal Conference Report.
