The recent developments in central and eastern Europe have changed the political landscape of the world. The dissolution of the Soviet Union, Czechoslovakia and Yugoslavia, the collapse of Communism in Europe, market reforms, and the processes of democratisation are all seminal events affecting not only the countries in transition but other states as well. All these changes presuppose fundamental legal reforms. In this process most of the countries in transition have adopted new constitutions where issues of participation in the international political order and questions of international law enjoy a prominent place. This book is one outcome of many research activities concerning these transitions in central and eastern Europe at the Centre of European Law, King's College London. It contains essays about constitutional reforms and international law by leading international judges and academics. It is edited by Mads Andenas, Director of the Centre of European Law at King's College London, Malgosia Fitzmaurice, Reader in International Law at Queen Mary and Westfield College, London, and Rein Mullerson, Professor in International Law at King's College.
