Book excerpt: The study of legal semiotics emphasizes the contingency and fluidity of legal concepts and stresses the existence of overlapping, competing and coexisting legal discourses. New problems, changing power structures and societal norms and new faces of injustice – all these force reconsideration, reformulation and even replacement of established doctrines. This book focuses on the application of law in a wide variety of contexts, including international politics and diplomatic practice.
