I would like to express my gratitude to the many people who contributed to this book in various ways. First and foremost, thanks are due to Professor Alan Boyle ( University of Edinburgh, formerly Queen Mary and Westfield College, University of London) for his constructive and critical advice, which involved many hours of discussing concepts and ideas. Professor Francesco Francioni ( University of Siena) made valuable comments and suggestions on parts of this work, and helped me in numerous practical ways during my research in Siena in 1992. I am also indebted to Jennifer Clapp and Susanne Rublack for interesting discussions on wasterelated issues, and to Ursula and Rolf Ganz-Blüttler for technical as well as moral support.
Numerous institutions and individuals provided me with essential information and documentation. In this context, special thanks are due to Pierre Portas and Ahmed Fathalla of the Secretariat of the Basel Convention ( Geneva) for responding to my frequent requests for pertinent information and updates, and for giving me access to their files. I am also grateful to the staff of the Secretariat of the London Convention ( IMO, London), the Documents Section of IMO, and the OECD Secretariat, for extensive information and documentation. On various occasions, Albert Mumma of Simmons & Simmons ( London) and Alier Deng of the Sudanese Mission to the UN ( Geneva) provided me with documents and information that would otherwise have been difficult to obtain within a reasonable period of time.
I am particularly grateful to Queen Mary and Westfield College, and to the Janggen-Pühn Foundation (St. Gallen, Switzerland) for the research scholarships awarded to me, as well as to the Committee of ViceChancellors and Principals of the Universities of the United Kingdom for awarding me an Overseas Research Studentship (ORS) for the duration of my research. Without the generous financial support of these institutions, this book could not have been written.
Last but not least, I wish to thank the staff of the Department of Law and the Centre for Commercial Law Studies ( Queen Mary and Westfield College) as well as the Institute of Public and International Law ( University of Siena) for considerably facilitating my task by giving me access to photocopying, telefax, and printing facilities. I would also like to thank the Research Centre for International Law ( University of Cambridge) for hosting me during the final months of my research.
