The right of peoples to self-determination seems well-settled and covered extensively in the scholarly record. Yet old Trotsky’s question – of whom is this right and to what? – haunts the self-determination literature. Somehow almost every work on it begins with an expression of puzzlement. This right turns out to be elusive, underdefined in its scope and content, paradoxical in almost every aspect. This book mobilises all powers of critical legal theory and modern philosophy to take the bull by its horns. Instead of ironing out the paradoxes, it aims to finally give them a proper explanation based on the concept of exception.
