In Justice in Extreme Cases, Darryl Robinson argues that the encounter between criminal law theory and international criminal law (ICL) can be illuminating in two directions: criminal law theory can challenge and improve ICL, and conversely, ICL's novel puzzles can challenge and improve mainstream criminal law theory. Robinson recommends a 'coherentist' method for discussions of principles, justice and justification. Coherentism recognizes that prevailing understandings are fallible, contingent human constructs. This book will be a valuable resource to scholars and jurists in ICL, as well as scholars of criminal law theory and legal philosophy.
