This book analyses constitutional change in federal and decentralizing countries from a comparative perspective. The authors identify structures, processes and strategies which have proven to favour successful constitutional amendment. Thereby, the book enables public officials, scholars, and students to learn from the constitutional reform experiences of other federal democracies and from practical suggestions how future reforms could be designed. From the Contents: The Relevance of Constitutional Change Constitutional Reform in "Co-operative" Federalism Constitutional Reform in Federal Systems with Divided Societies Devolution and Regionalisation in Federalising States Processes of Ratification Evolution after a Constitutional Reform Conclusion
