During a turbulent time for constitutional law in general, and human rights law in particular, it is refreshing to read a book which radiates with optimism. Works by former judges are often fascinating insights into the judicial mind. This book, by former High Court judge Michael Tugendhat, is therefore to be doubly welcomed. . . . Tugendhat has taken care to make the book accessible - an admirable feat for such complex subject matter. He has explained difficult concepts in clear language and presented his thoughts in short, snappy chapters. Shona Wilson Stark, Cambridge Law Journal
