The book provides a broad and interdisciplinary approach to the doctrine of self-defence in both domestic criminal and international law. In particular it focuses on the requirement of imminence, which deals with the question of when individuals or States may legitimately resort to defensive force against a serious danger or harm.
Drawing from scholarship across law, history, politics and philosophy, this book explores the permissibility of employing preventive force under the law of individual and national self-defence. The book illustrates how the law of international self-defence, and in particular the requirement of imminence, has been subjected to controversy in parallel with its domestic counterpart. In both disciplines the debate over imminence is centred on similar concerns, issues and tensions despite the fact the arguments put forward are designed to address different scenarios. The book surveys the roots, role, rationale, and objectives of self-defence and questions whether the requirement of imminence should be removed from the traditional contours of the self-defence doctrine in national and international law.
