The Inherent Right Of Self Defence In International Law

Determining the earliest point in time at which international law authorises a state to exercise its inherent right of self-defence is an issue which has been debated, but unsatisfactorily reasoned, by scholars and states since the 1960’s. Yet it remains arguably the most pressing question of law that faces the international community. This book unravels the legal and factual complications which have obscured the answer to this question. In contrast to most other works, it takes an historic approach by tracing the evolution of the rights, rules and principles of international law which have governed the use of force by states since the 16th century. Its emphasis on self-defence provides the reader with a new and complete understanding of how and why the international legal framework limits defensive force to repelling an imminent threat or use of offensive force which is directed at the territory of a state. Taking an historic approach enables this book to resurrect an understanding of the human defensive instinct which has guided the formation of the international law of self-defence. It also explains the true legal nature and scope of the inherent right of self-defence, of anticipatory self-defence and provides a definition of the legal commencement of an armed attack for the purpose of Article 51 of the Charter. Finally, the reader will receive a unique source of research materials and analysis of state practice and of scholarly works concerning self-defence and the use of force since the 16th century, which is suitable for all readers of international law around the world.

The book examines in detail one of the most controversial topic in current international law, namely the scope and extent of the right of individual self-defense. The book carefully traces the paths which have been followed in the developing legal debate on self-defense. The author uses numerous case-studies of incidents involving the use of force in alleged self-defense (such as the Entebbe Incident 1976, the Nicaragua Case 1986 or the Israeli-Lebanese conflict of 2006) which have formed the central point of scholarly debate. The author's conclusions are based not only on thorough analysis of academic discussions but also of the practice of States and international bodies, especially of the United Nations Organization. At the outset of the book the author reviews the historical context and the customary evolution of the right of self-defense. Reference is made to the famous Caroline Case of 1837, which set the necessary conditions of lawful exercise of self-defense. Next, the author examines the concept and legal nature of self-defense, carefully assessing the customary conditions of necessity, proportionality and immediacy derived from the Caroline Case. As the occurrence of an "armed attack" is a conditio sine qua non of lawful invocation of self-defense, several modalities of an armed attack are attentively evaluated such as its constituent elements, beginning or scale. The author explores, whether reactions to acts of international terrorism committed by a non-State may be based on the right of self-defense. In times of global terrorist networks it is highly desirable to attach special attention to use of force in self-defense as a remedy against serious acts of terrorism. Thorough analysis of State practice is shown on several examples from recent history - the U.S. air raid on Libya in 1986 and on Baghdad in 1993 and relatively recent air strikes on Sudan and Afghanistan in 1998. Reference is also made to the most striking example - the Al-Qaeda attack on the United States in 2001. The validity of claims of anticipatory/preventive self-defense is examined on a theoretical level and then applied to the specific details of the Israeli air strike on the Osiraq Nuclear Reactor in 1981. The two main approaches to preventive self-defense - "restrictive" and "traditional" - are then discussed in detail. Brief analysis is also devoted to the nature of the so-called - pre-emptive - self-defense indicating its current position under international law.

Yoram Dinstein's influential textbook is an indispensable guide to the legal issues of war and peace, armed attack, self-defence and enforcement measures taken under the aegis of the Security Council. This fifth edition incorporates recent treaties such as the Kampala amendments of the Statute of the International Criminal Court, new case law from the International Court of Justice and other tribunals, and contemporary doctrinal debates. Several new supplementary sections are also included, which take into account recent conflicts around the world, and consideration is given to new resolutions of the Security Council. With many segments having been rewritten to reflect recent State practice, this book remains a wide-ranging and highly readable introduction to the legal issues surrounding war and self-defence.

Collective self-defence can be defined as the use of military force by one or more states to aid another state that is an innocent victim of armed attack. However, it is a legal justification that is open to abuse and its exercise risks escalating conflict. Recent years have seen an unprecedented increase in the number of collective self-defence claims. It has been the main basis for US-led action in Syria (2014-) and was advanced by Russia in relation to its full-scale invasion of Ukraine (2022-). Yet there still has been little analysis of collective self-defence in international law. This book crucially progresses the debate on various fundamental and under-explored questions about the conceptual nature of collective self-defence and the requirements for its operation. Green provides the most detailed and extensive account of collective self-defence to date, at a time when it is being invoked more than ever before.

This book defines the right of self-defence as understood in and before 1945 and offers a possible better alternative for interpreting the significance of the precondition provided for in the Article 51 of the United Nations Charter.

The legal rules governing the use of force between States are one of the most fundamental, and the most controversial, aspects of international law. An essential part of this subject is the question of when, and to what extent, a State may lawfully use force against another in self-defence. However, the parameters of this inherent right remain obscure, despite the best efforts of scholars and, notably, the International Court of Justice. This book examines the burgeoning relationship between the ICJ and the right of self-defence. Since 2003 there have been three major decisions of the ICJ that have dealt directly with the law governing self-defence actions, in contrast to only two such cases in the preceding fifty years. This, then, is an opportune moment to reconsider the jurisprudence of the Court on this issue. This book is the first of its kind to comprehensively draw together and then assess the merits of this jurisprudence. It argues that the contribution of the ICJ has been confused and unhelpful, and compounds inadequacies in existing customary international law. The ICJ's fundamental conception of a primary criterion of 'armed attack' as constituting a qualitatively grave use of force is brought into question. The book then goes on to examine the underlying causes of the problems that have emerged in the jurisprudence on this crucial issue. Winner of the American Society of International Law's Lieber Society Book Prize 2009 Dr Green's monograph demonstrates a thorough understanding of the law of self-defence, coupled with an informed and evaluative discussion of the role and function of the International Court. It is an impressive analysis of the International Court of Justice's jurisprudence on self-defence. Professor Iain Scobbie, Judge of the American Society of International Law's Lieber Society Book Prize 2009, Sir Joseph Hotung Research Professor, School of Oriental and African Studies, London James Green's "The International Court of Justice and Self-Defence in International Law" usefully draws together the jurisprudence of the International Court of Justice on the international law governing self-defence. The work could not be more timely in light of both contemporary State practice and the Court's recent controversial judgements on the topic. Of particular note is his analysis of the very complex, and as yet unsettled, notion of "armed attack."
