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.

The 1968 Nuclear Non-proliferation Treaty has proven the most complicated and controversial of all arms control treaties, both in principle and in practice. Statements of nuclear-weapon States from the Cold War to the present, led by the United States, show a disproportionate prioritization of the non-proliferation pillar of the Treaty, and an unwarranted underprioritization of the civilian energy development and disarmament pillars of the treaty. This book argues that the way in which nuclear-weapon States have interpreted the Treaty has laid the legal foundation for a number of policies related to trade in civilian nuclear energy technologies and nuclear weapons disarmament. These policies circumscribe the rights of non-nuclear-weapon States under Article IV of the Treaty by imposing conditions on the supply of civilian nuclear technologies. They also provide for the renewal and maintaintenance, and in some cases further development of the nuclear weapons arsenals of nuclear-weapon States. The book provides a legal analysis of this trend in treaty interpretation by nuclear-weapon States and the policies for which it has provided legal justification. It argues, through a close and systematic examination of the Treaty by reference to the rules of treaty interpretation found in the 1969 Vienna Convention on the Law of Treaties, that this disproportionate prioritization of the non-proliferation pillar of the Treaty leads to erroneous legal interpretations in light of the original balance of principles underlying the Treaty, prejudicing the legitimate legal interests of non-nuclear-weapon States.

Nuclear proliferation poses a serious threat to international peace and security. The non-proliferation regime is the body of public international law that aims to counter this threat. It has been a cornerstone of global security for decades. This book analyses its main instruments. The book focuses on the Nuclear Non-proliferation Treaty, international trade controls and the International Atomic Energy Agency. It describes the internal mechanics of these mechanisms, their development, and their strengths and weaknesses. It shows how they together are the basis of a political-legal order that is more than the sum of its parts, offering new insights on the role of international law in an area dominated by security-driven politics.

Rising concern over the increasing threat of nuclear war impelled the 2017 United Nations (UN) negotiations and adoption by 122 UN member states of a Treaty on the Prohibition of Nuclear Weapons. The Treaty seeks to ban nuclear weapons globally in the same way chemical and biological weapons have already been prohibited. This book provides the first in-depth comprehensive analysis of the implications and possibilities of the new treaty, drawing on the insights of international relations, international laws, and disarmament experts and specialists from Europe, America, the Asia-Pacific, and the UN. In a context where existing nuclear weapon states have so far declined to be party to the new treaty, the book examines not only its emergence and significance but also the prospects and possibilities for its implementation, the challenges associated with verifying the new agreement, the role of both civil society and governments, and the treaty’s wider implications in addressing regional and global nuclear threats. This book was originally published as a special issue of Global Change, Peace & Security but additionally includes the special section articles on the treaty in the Journal for Peace and Nuclear Disarmament.

The Treaty on the Prohibition of Nuclear Weapons (2017) sets out to challenge deterrence policies and military defence doctrines, taking a humanitarian approach intended to disrupt the nuclear status quo. States with nuclear weapons oppose its very existence, neither participating in its development nor adopting its final text. Civil society groups seem determined, however, to stigmatize and delegitimize nuclear weapons towards their abolition. This book analyzes how the Treaty influences the international security architecture, examining legal, institutional and diplomatic implications of the Treaty and exploring its real and potential impact for both states acceding to the Treaty and those opposing it. It concludes with practical recommendations for international lawyers and policymakers regarding non-proliferation and disarmament matters, ultimately noting that nuclear weapons threaten peace, and everyone should have the right to nuclear peace and freedom from nuclear fear.
