The contents of the Yearbook reflect the diversity of Canadian and international thought, opinion, and practice on current problems of international law. Included this year are cutting-edge analyses on such varied topics as the plea of superior orders in international criminal law; interaction of the economic and environmental dimensions of the principle of sustainable development; and legal dimensions of Canada's dispute with the European Union over international trade in seal products. Each volume includes a notes and comments section; a digest of international economic law; a section on current Canadian practice in international law; a digest of important Canadian cases; and book reviews.
