International claims commissions have, over the last few decades, established themselves as important and permanent fixtures in international adjudication. This book provides a comprehensive review and analysis of the workings and mechanics of claims commissions to assess their success and predict their utility in the future. The book examines the legal framework of an international claims commission and the basic elements its processing procedure, as well as exploring the difficulties and challenges associated with operating costs, remedies and compliance with judgments. International claims commissions are created ad hoc to consider large numbers of complex legal claims resulting from an international upheaval, making them important international dispute resolution mechanisms. By focusing in large part on the examples set by the United Nations Claims Commissions, the Iran US Claims Tribunal, and the Eritrea Ethiopia Claims Commission, the authors assess the reasons to establish a claims commission by discussing their legal and operating structures, issues related to evidence and costs and the challenges and successes of creating them. The book concludes with a detailed analysis of lessons learnt to guide policy makers in the creation of future claims commissions. Written by two academics and a former practitioner this book is a practical resource for international law academics; counsel and judges in international courts and tribunals; policy makers in international organizations and foreign ministries, and diplomats.
