How does international law change? How does it adapt to meet global challenges in a volatile social and political context? The Many Paths of Change in International Law offers fresh, theoretically informed, and empirically rich answers to these questions. It traces drivers, conditions, and consequences of change across the different fields of international law and paints a complex and varied picture very much in contrast with the relatively static imagery
prevalent in many accounts today.
Drawing on inspirations from international law, international relations, sociology, and legal theory, this book explores how international law changes through means other than treaty-making. Highlighting the social dynamics through which different areas and institutional contexts have generated their own pathways, it presents a theoretical framework for tracing change processes and the conditions that affect their success. Based on this framework, each contribution illuminates the paths of
change we observe in contemporary international law. The explorations centre on strategies, forms, forces, and social contexts and draw on primary source material and in-depth case studies.
Overall, the volume offers a fascinating account of an international legal order in flux-with a dynamic not captured through traditional doctrinal lenses-and helps situate change processes and their varied implications in international law and politics. A relevant book for everyone wanting to understand change and its consequences in international law.
