This book explores the global phenomenon of migration, transplantation, and borrowing of constitutional ideas. It combines conceptual and normative approaches, to dissect a phenomenon which has been both praised and maligned in current political and academic discourse.

The contributors consider constitutional transplantation as a specific case of migration of ideas, and place it within that broader intellectual framework of movement of knowledge. They analyse, from historical, conceptual, and normative angles, the transplantation of constitutions and constitutional ideas from one state to another, and the role played by existing cultures and histories in the reception of constitutional provisions and ideas.

The book takes a broad view of the term ‘constitutional’. The results of the movement of constitutional ideas can be found outside, as well as within, the law, and the implications of such movement go beyond it. The authors are drawn from the fields of comparative constitutional law, medieval history, political philosophy, private law, and administration of justice.

It reflects a view that the study of non-hegemonic systems, as well as hegemonic systems, is important in understanding transplantation of constitutional ideas, both as sources of transplants and as their receivers, and includes discussions of constitutions in Latin America, Asia, Europe, and North America.
