This book examines the European system for the protection of fundamental rights. The aim is to identify the constitutional dynamics that occur as a result of the interaction between state and transnational human rights standards. Fabbrini compares the European system with the US federal system based on four case studies. Fabbrini sets out the critical issues with clarity, and in providing extensive empirical case studies and a comparative methodology, the breadth of his scholarship is impressive. He writes with lucidity and clarity and provides useful summaries at the end of each chapter. This book is a clear and very useful addition to the perplexing topic of human rights protection in Europe, and a signpost for the way forward in the debate.
