INTERNATIONAL COURTS AND TRIBUNALS SERIES General Editors: Ruth Mackenzie, Cesare P.R. Romano, and Philippe Sands The European Court of Justice and International Courts INTERNATIONAL COURTS AND TRIBUNALS SERIES General Editors: Ruth Mackenzie, Cesare P.R. Romano, and Philippe Sands A distinctive feature of modern international society is the increase in the number of international judicial bodies and dispute settlement and implementation control bodies; in their case-loads; and in the range and importance of the issues they are called upon to address. These factors reflect a new stage in the delivery of international justice. The International Courts and Tribunals series has been established to encourage the publication of independent and scholarly works which address, in critical and analytical fashion, the legal and policy aspects of the functioning of international courts and tribunals, including their institutional, substantive, and procedural aspects.

To Jennifer Preface This book started out as a doctoral thesis many years ago at my alma mater in Erlangen. I passed my viva almost to the day five years ago and the topic has stayed with me since. With the benefit of hindsight it was perhaps a little foolish to write it in German—the language in which the book first appeared. At the same time, however, the five additional years leading to its publication in English allowed the book to grow with me academically. The passage of time made a number of updates necessary and enabled me, I would hope, to improve its substance. Literature and case law are accurate as of the end of August 2014. I was able to include a few late coming cases and articles after that date, in particular the Court of Justice's Opinion 2/13 on EU accession to the ECHR. While research and writing, in the legal field at least, are solitary activities, their quality is considerably improved by a good support network. I have been fortunate enough to have profited from working in inspiring environments: at the University of Erlangen, where I learnt my trade and where I made the decision to become an academic; at University College London, where I had my first job in the UK as DAAD-Lecturer, and where most of the research for this book was carried out; at the University of Surrey, where I met some of my best academic friends; and at the University of Edinburgh, where I have the privilege of being based in outstanding academic surroundings and where this work was completed. I have profited enor- mously from exchanges with colleagues, from talks and lectures, workshops and conferences organized at these institutions and I am very grateful for this. I would in particular like to thank my doctoral supervisor Bernhard W. Wegener, who inspired me to write a thesis around the (then pending) MOX Plant case. In addition, I would like to thank those friends and colleagues who have read and commented on various parts of this book: Filippo Fontanelli, Apolline Roger, Konstanze von Papp, Neil Walker, as well as Ariadne Panagopoulou, who provided valuable research assistance. Thanks are also due to the team at OUP, in particular Merel Alstein and Emma Endean, for their excellent support. Finally, I am eternally grateful to my parents for supporting me in whatever I have done and am doing and, in particular, to my wife Jennifer, to whom this book is dedicated. I am sure she knows why.
