The break-up of the Soviet Union, Yugoslavia and Czechoslovakia and the unification of Germany in the 1990s marked the dramatic return to center stage in international law of the issue of State succession. This book deals with one particularly controversial aspect of State succession that until now has not received much attention: the question of State succession to international responsibility. In State Succession to International Responsibility the international lawyer and scholar Patrick Dumberry addresses the question, critical for our times, whether or not a new State may be held responsible for wrongful acts committed before its independence by the predecessor State. He also considers the reverse situation: whether or not a new State may claim reparations for wrongful acts committed before its independence by third parties and which affected the predecessor State or one of its nationals. State Succession to International Responsibility contains the most comprehensive analysis ever published of doctrine and State practice related to these questions. It is the first attempt to examine systematically State conduct, both historical and modern, with a view to identifying the factors and circumstances under which rights and obligations of a predecessor State may be transferred to a new State.
