Provides an in-depth study of the theory, history, practice, and interpretation of customary international law.

The global landscape has changed profoundly over the past decades. As a result, the making of international law and the way we think about it has become more and more diversified. This Research Handbook offers a comprehensive guide to the theory and practice of international lawmaking today. It takes stock at both the conceptual and the empirical levels of the instruments, processes, and actors involved in the making of international law. The editors have taken an approach which carefully combines theory and practice in order to provide both an overview and a critical reflection of international lawmaking. Comprehensive and well-structured, the book contains essays by leading scholars on key aspects of international lawmaking and on lawmaking in the main issue areas. Attention is paid to classic processes as well as new developments and shades of normativity. This timely and authoritative Handbook will be a valuable resource for academics, students, legal practitioners, diplomats, government and international organization officials as well as civil society representatives.

Professor Suy occupies a prominent place in international law, both as an academic lawyer as well as the former Under-Secretary-General & Legal Counsel of the United Nations. His activities as a teacher, scholar, UN Legal Counsel, keynote speaker on many occasions & as a legal advisor to Belgian & foreign governmental authorities naturally led to the sub-divisions of this volume, such as the law of international organizations, the law of the European Union, the law of armed conflict, & the peaceful settlement of disputes. The contributions, all by friends of Eric Suy, present the vast panorama of his intellectual pursuits.

Two fish are swimming in a pond. 'Do you know what?' the fish asks his friend. 'No, tell me.' 'I was talking to a frog the other day. And he told me that we are surrounded by water!' His friend looks at him with great scepticism: 'Water? Whats that? Show me some water!' International lawyers often find themselves focused on the practice of the law rather than the underlying theories. This book is an attempt to stir up 'the water' that international lawyers swim in. It analyses a range of theoretical approaches to international law and invites readers to engage with different ways of legal thinking in order to familiarize themselves with the water all around us, of which we hardly have any perception. The main aim of this book is to provide interested scholars, practitioners, and students of international law and other disciplines with an introduction to various international legal theories, their genealogies, and possible critiques. By providing an analytical approach to international legal theory, the book encourages readers to enhance their sensitivity to these different approaches and to consider how the presuppositions behind each theory affect analysis, research, and practice in international law. International Law Theories is intended to assist students, scholars, and practitioners in reflecting more generally about how knowledge is formed in the field.

Amnesty, Serious Crimes and International Law examines the permissibility of amnesties for serious crimes in the contemporary international order. In the last few decades, there has been a growing tendency to consider that amnesties are prohibited in respect of certain grave crimes. However, the question remains controversial as there is no explicit treaty ban and general amnesties continue to be frequently issued in post-conflict and transitional contexts. The first part of the book explores the use of amnesties from antiquity to the present day. It reviews amnesty traditions in ancient societies and provides a global picture of modern amnesties. In parallel, it traces the development of the accountability paradigm underpinning the current prohibitive stance on amnesties. The second part assesses the position of modern international law on amnesties. It comprehensively analyses the main arguments supporting the existence of a general amnesty ban, including the duty to prosecute international crimes, the right to redress of victims of human rights violations, international standards and trends in state practice, and the mandate of international criminal courts. The book argues that, while international legal or policy requirements restrict the freedom of states to extend amnesty in respect of serious crimes, or the effectiveness of amnesty measures in preventing the prosecution of such crimes, these restrictions do not add up to an absolute and universal prohibition.
