Within societies, on a national level, self-defence may be used as a defence against the use of force in order to prevent crime against oneself, a fellow human being or even property. Between societies on the international level, self-defence was traditionally linked to the concept of armed attack. However, in today’s world, new forms of aggression, the concept of collective security, and an increasing interaction between national and international law necessitate a reassessment of the concept of self-defence. The first session of the Hague Colloquium on the Fundamental Principles of Law, on the topic of self-defence and honouring Shabtai Rosenne, the first Laureate of the Hague Prize for Intenational Law, brought together experts from both academic and professional circles to debate the notion of self-defence in the world of today. Both the Colloquium and this subsequent publication make a valuable contribution to the development of the law by recognising the sources of the principle of self-defence, and the theories underlying it, by following its path of evolution and by reassessing its current status. The essays are accompanied by a remarkably full and useful bibliography and by documentary materials, many of which are difficult to obtain elsewhere.

This book will contribute constructively to stimulating scholarship and research in the field of self-defence; it provides food for thought, and will hopefully inspire more colloquia and publications on the topic.

Self-defence may be used as a defence for the use of force in order to prevent crime against oneself, a fellow human-being or property. Although traditionally linked to the concept of armed attack, new forms of aggression, the concept of collective security and an increasing interaction between national and international law have forced a reassessment of self-defence. The first Hague Colloquium on the Fundamental Principles of Law on the topic of self-defence brought together experts from both academic and professional circles to debate the notion of self-defence. Both the Colloquium and this subsequent publication make a valuable contribution to the development of the law by recognising the sources of the principle of self-defence, and the theories behind it, by following its path of evolution and by reassessing its current status.
