A collection of essays on the various aspects of the legal sources of international law, including theories of the origin of international law, explanation of its binding force, normative hierarchies and the relation of international law and politics.

Provides an in-depth study of the theory, history, practice, and interpretation of customary international law.

States often regard themselves bound by treaty rules which have developed under customary international law, even though many of the treaties themselves have not been ratified. The Law of the Sea Convention, for instance, has generated new customary rules which modified the 1958 Geneva Conventions. These & many other issues are dealt with clearly & systematically in this informative handbook on the relations between written & unwritten international law. The conclusions of the first edition of Customary International Law & Treaties were largely confirmed by the International Court of Justice in the Nicaragua Case. This fully revised second edition, while basing itself on the original version, brings the subject up to date.

"A study of their interactions and interrelations, with special consideration of the 1969 Vienna Convention on the Law of Treaties."--T.p.

Interest in international law has increased greatly over the past decade, largely because of its central place in discussions such as the Iraq War and Guantanamo, the World Trade Organisation, the anti-capitalist movement, the Kyoto Convention on climate change, and the apparent failure of the international system to deal with the situations in Palestine and Darfur, and the plights of refugees and illegal immigrants around the world. This Very Short Introduction explains what international law is, what its role in international society is, and how it operates. Vaughan Lowe examines what international law can and cannot do and what it is and what it isn't doing to make the world a better place. Focussing on the problems the world faces, Lowe uses terrorism, environmental change, poverty, and international violence to demonstrate the theories and practice of international law, and how the principles can be used for international co-operation.

Fundamentals of Public International Law, by Giovanni Distefano, provides an overview of public international law’s main principles and fundamental institutions. By introducing the foundations of the legal reasoning underlying public international law, the extensive volume offers essential tools for any international lawyer, regardless of the specific field of specialization. Dealing expansively with subjects, sources and guarantees of international law, university students, scholars and practitioners alike will benefit from the book’s treatment of what has been called the “Institutes” of public international law.

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.
