On July 8, 1996 the International Court of Justice handed down two Advisory Opinions on the legality of nuclear weapons. This book offers a comprehensive study of those opinions. More than thirty internationally respected experts contribute their analyses of the status of nuclear weapons in international law across all its sectors: use of force, humanitarian law, environment and human rights. The contributions also assess the implications of the opinions for international organizations and the international judicial function. Contributors include lawyers, academics, diplomats and advisors to international bodies.
