This book is a revised and updated version of the doctoral dissertation which I defended at the Faculty of Law of the Humboldt University Berlin in December 2009. As this is a book about complicity, it is only fair to gratefully acknowledge the ‘aid and assistance’ that I received from a number of people. It should very well be understood that this ‘complicity’ does not entail any responsibility for errors and misconceptions which can only be attributed to the author.
First of all, I would like to thank my academic teacher, Professor Georg Nolte. He supervised my work as a doctoral candidate. My way of thinking about international law has been deeply influenced by him. I am especially grateful for the academic guidance with which he has accompanied my work so far, as well as for his personal cordiality and warmth. He also initially directed my attention to the topic of this book.
