The volume discusses the legal interpretation and implementation of the three pillars of the Treaty of the Non-Proliferation of Nuclear Weapons, 1968, regarding the non-proliferation of nuclear weapons; the right to develop research, production and use of nuclear energy for peaceful purposes; and issues relating to nuclear disarmament. It examines the status of international law regarding nuclear capacity, considering competing legal approaches to the development of nuclear technology, non-proliferation, disarmament and regulating nuclear weapons within a contemporary international context.
