`This study confirms Professor Sarooshi as a leading writer today in the field of international organizations - a field in which he has immersed himself and taken on the challenge of its ever expanding and deepening nature. As with The United Nations and the Development of Collective Security, he has married impressive knowledge of detail with original conceptual thinking. The result is a book that is at once informative and challenging.' Judge Rosalyn Higgins, DBE, QC, President of the International Court of Justice `This may be the most important future terrain for international law generally, and will also certainly challenge some of the fundamental assumptions of general international law. This is a path breaking work that provides important insights which practitioners and scholars will need as the world struggles with change and circumstances creating enormous risks but also great opportunities in the wake of economic, political, and scientific forces beyond the traditional controls available to individual nation states.' Professor John H. Jackson, Georgetown University Law Center `The clarity and thoroughness of his analysis provides a firm foundation for the development of the law in this important area.' Professor Vaughan Lowe and Professor Ian Brownlie QC (Emeritus), Series Editors' Preface `The backing of such a renowned and acclaimed author like Dan Sarooshi will undoubtedly shore up the credibility of such a progressive proposal.' Global Law Books `Professor Sarooshi has examined in rich detail the many modes by which national powers are being conferred, transferred or delegated to international organizations to the point that sovereignty itself has become a "contestable" concept. This is an original and important book.' Professor Michael Reisman, Yale Law School
