h is book was accepted by the Faculty of Law of the University of Hamburg as the dissertation for my doctorate in law in the spring of 2008. It was updated to its current form for publication. I owe special thanks to Prof. Dr. Dr. . Rüdiger Wolfrum, professor of international law at the University of Heidelberg, director of the Max Planck Institute for Comparative Public Law and International Law and judge at the International Tribunal for the Law of the Sea, for his supervision and timely review of my submissions and his support when I was a senior research.
