This book deals with the role that private international law may play in times of global crises. Addressing current legal frameworks, unresolved issues and potential reforms it demonstrates how private international law can evolve from a predominantly coordinating discipline into one that is normatively engaged and globally responsive. Contributors illustrate how private international law can provide solutions to some of the most pressing challenges of the 21st century, including war and armed conflicts, rule of law backsliding, protection of human rights in global supply chains, climate change and sustainability. Through doctrinal and normative analyses, they explore the structural and conceptual changes necessary to mitigate the effects of these crises. The book advocates for a re-evaluation of private international law's traditional role, proposing a reconceptualization that highlights its potential to resolve global issues and achieve justice. This book is an essential read for scholars and students of private international law, and international law more widely. It is also beneficial to practitioners in these fields, particularly those working in international civil procedure.
