This book presents a collection of essays on key topics and new perspectives on the EU's Area of Freedom, Security and Justice (AFSJ).As the AFSJ becomes more and more intertwined with 'mainstream' EU law, this edited collection provides a timely analysis of the merger between the two. Showcasing a selection of work from key thinkers in this field, the book is organised around the major AFSJ themes of crime, security, border control, civil law cooperation and important 'meta' issues of governance and constitutional law.
