"A sweeping exploration of the authority of international courts across different audiences. Broad in its empirical scope and unique in its focus on de facto authority, this is the most important account to date of the role of international courts in world politics. Employing a common framework across 13 different judicial institutions, International Court Authority is a masterwork." - David A. Lake, Gerri-Ann and Gary E. Jacobs Professor of Social Sciences, University of California, San Diego

"Adopting an historical and comparative perspective, this extremely valuable investigation of the authority of international courts and tribunals offers an insightful tour of the debates surrounding this delicate and cross-cutting issue. Rich and multilayered, thought provoking and convincing, eighteen extremely accomplished scholars restore historical nuance to the question of how contextual factors beyond the control of international judges affect international court authority. International Court Authority raises important questions that deserve to attract more attention in contemporary scholarship." - Hélène Ruiz Fabri, Director of the Max Planck Institute Luxembourg for Procedural Law

"International Court Authority is a first-of-its-kind account of the factors that shape the de facto authority of international courts. Path-breaking and comprehensive, the authors offer a general theory that grapples with the legal, political, and social challenges international judges face. A group of scholars then examines a rich array of judicial bodies, demonstrating the strength of a truly interdisciplinary approach. A must read for the designers of future international courts, for every international judge, and of course for scholars of international adjudication." - Eyal Benvenisti, Whewell Professor of International Law, University of Cambridge
