'This book is fascinating and rich in insight. The ad hoc tribunals came about at a rare moment of East-West accord. They gave a voice to war crimes victims and put the criminals in the dock. They also produced a historical record, opened the way to the International Criminal Court and even advanced peace in the Balkans. But that political moment may have passed, and in Syria today, as the authors point out, there's no accountability and little hope of international justice.' Roy Gutman, Pulitzer-Prize winning journalist 'This excellent book will be of significant interest to jurists, practitioners and scholars studying the contributions of the ad hoc tribunals, as well as to those interested in international criminal law in general.' Christina Van Den Wyngaert, Judge of the International Criminal Court (2009-18) 'The Yugoslavia and the Rwanda tribunals ignited the rapid development of international criminal law over the past two decades. This book provides an outstanding account of how these institutions have established a lasting legacy by shaping this growing field of law.' Stephen Rapp, former US Ambassador-at-large for War Crimes Issues 'At a time when multilateral institutions are under attack, as is multilateralism itself, this book provides a timely reminder of what two of its products, the ICTY and ICTR, managed to accomplish despite the odds.' Jose Alvarez, Herbert and Rose Rubin Professor of International Law, New York University
