The book examines current debates about the emergence of an international legal norm of democratic governance and also considers some of the wider theoretical issues to which those debates give rise. It asks should international law seek to promote democratic political arrangements? If so, on what basis, and using which of the many competing conceptions of democracy? "Susan Marks has written a brilliantly provocative and sophisticated book giving a strikingly original and far-reaching slant to her analysis. The Riddle of All Constitutions provides an excellent critique of mainstream proposals about how to bring the pursuit of democracy into the thinking and interpretations of international Law." A significant and critical contribution to the theory of international law Susan Marks is a Lecturer in Law at the University of Cambridge
