International law is constantly navigating the tension between preserving the status quo and adapting to new exigencies. But when and how do such adaptation processes give way to a more profound transformation, if not a crisis of international law? To address the question of how attacks on the international legal order are changing the value orientation of international law, this book brings together scholars of international law and international relations. By combining theoretical and methodological analyses with individual case studies, this book offers readers conceptualizations and tools to systematically examine value change and explore the drivers and mechanisms of these processes. These case studies scrutinize value change in the foundational norms of the post-1945 order and in norms representing the rise of the international legal order post-1990. They cover diverse issues: the prohibition of torture, the protection of women's rights, the prohibition of the use of force, the nonproliferation of nuclear weapons, sustainability norms, and accountability for core international crimes. The challenges to each norm, the reactions by norm defenders, and the fate of each norm are also studied. Combined, the analyses show that while a few norms have remained surprisingly robust, several are changing, either in substance or in legal or social validity. The book concludes by integrating the conceptual and empirical insights from this interdisciplinary exchange to assess and explain the ambiguous nature of value change in international law beyond the extremes of mere progress or decline.

This book conducts the first ever comprehensive study of the ICRC’s interpretations and law-ascertainments. It analyses in detail their impact on the development of international humanitarian law and international law in general as well as the reasons for their impact. This analysis involves the discussion of the ICRC’s authority. Is it legal or just factual authority? The analysis also illuminates the direction that IHL – and international law in general – develops. This insight sheds light on the question of the current type of international law, i.e., what international law is and who makes it.

This Research Handbook examines the complex relationship between international law and domestic legal systems. An interdisciplinary range of experts analyse the topic from historical, conceptual, critical and doctrinal perspectives, setting the tone for future reflections on the development of the international legal order.

This book challenges the idea that international law looks the same from anywhere in the world. Instead, how international lawyers understand and approach their field is often deeply influenced by the national contexts in which they lived, studied, and worked. International law in the United States and in the United Kingdom looks different compared to international law in China and Russia, though some approaches (particularly Western, Anglo-American ones) are more influential outside their borders than others. Given shifts in geopolitical power and the rise of non-Western powers like China, it is increasingly important for international lawyers to understand how others coming from diverse backgrounds approach the field. By examining the international law academies and textbooks of the five permanent members of the UN Security Council, Roberts provides a window into these different communities of international lawyers, and she uncovers some of the similarities and differences in how they understand and approach international law.

This insightful book analyses the issue of norm erosion in international law by examining arms transfers to non-state actors. Balancing empirical research with legal theory, the author dissects recent case studies, tracing individual changes in norms against a background of systemic transformation.

Uses the focus of environmental disputes to develop a novel comparative analysis of the functions of international courts and tribunals.
