In Beyond Imperfect Justice (Brill, 2022), Dr Talita Dias (Jesus College & ELAC, Oxford) explores how the principles of legality and fair labelling have developed in international criminal law, from Nuremberg to the International Criminal Court and beyond. It features a comprehensive survey of domestic and international case law, treaties, and other materials, carefully unpacking the different rationales and elements of each principle and the various rules to which they apply.
