Nuclear Weapons under International Law is a comprehensive treatment of nuclear weapons under key international law regimes. It critically reviews international law governing nuclear weapons with regard to the inter-state use of force, international humanitarian law, human rights law, disarmament law, and environmental law, and discusses where relevant the International Court of Justice's 1996 Advisory Opinion. Unique in its approach, it draws upon contributions from expert legal scholars and international law practitioners who have worked with conventional and non-conventional arms control and disarmament issues. As a result, this book embraces academic consideration of legal questions within the context of broader political debates about the status of nuclear weapons under international law.

This Commentary offers detailed background and analysis of the Treaty on the Prohibition of Nuclear Weapons, which was adopted at the UN Headquarters in New York in July 2017. The Treaty comprehensively prohibits the use, development, export, and possession of nuclear weapons. Stuart Casey-Maslen, a leading expert in the field who served as legal adviser to the Austrian Delegation during the negotiations of this Treaty, works through article by article, describing how each provision was negotiated and what it implies for states that join the Treaty. As the Treaty provisions cut across various branches of international law, the Commentary goes beyond a discussion of disarmament to consider the law of armed conflict, human rights, and the law on inter-state use of force. The Commentary examines the relationship with other treaties addressing nuclear weapons, in particular the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). Background on the development and possession of nuclear weapons and theories of nuclear deterrence is provided. Particular attention is paid to controversial issues such as assistance for prohibited activities, the meaning of 'threaten to use', and the definition of nuclear explosive devices. Casey-Maslen also considers whether a member of NATO or other nuclear alliance can lawfully become a state party to the Treaty.

The debate on no-first-use of nuclear weapons has been conducted on a number of fronts. First use of nuclear weapons has come under challenge from many different directions: from church synods, from international lawyers, in debates at the United Nations, and from strategic thinkers. Originally published in 1984, this book takes stock for and against no-first-use and examines the political, military and arms control implications of such a commitment.

The contributors to this book describe, discuss, and evaluate the normative reframing brought about by the Treaty on the Prohibition of Nuclear Weapons (the Ban Treaty), taking you on a journey through its genesis and negotiation history to the shape of the emerging global nuclear order. Adopted by the United Nations on 7 July 2017, the Ban Treaty came into effect on 22 January 2021. For advocates and supporters, weapons that were always immoral are now also illegal. To critics, it represents a profound threat to the stability of the existing global nuclear order with the Nuclear Non-proliferation Treaty as the normative anchor. As the most significant leap in nuclear disarmament in fifty years and a rare case study of successful state-civil society partnership in multilateral diplomacy, the Ban Treaty challenges the established order. The book’s contributors are leading experts on the Ban Treaty, including senior scholars, policymakers and civil society activists. A vital guide to the Ban Treaty for students of nuclear disarmament, arms control and diplomacy as well as for policymakers in those fields.

Banning the Bomb: The Politics of Norm Creation participates in the ongoing debate on international norm creation between Realists and Constructivists in international relations scholarship. The author argues from a Constructivist provenance that it is critical to examine the role of international non-state coalitions in order to appreciate the broader political context. Well-researched and rich in detail, this book will be a valuable resource for scholars and students of international relations, disarmament, and peace studies.
