The Procedural Criminal Law Cooperation of the EU

This book is the second volume that is based on research conducted within the project “Towards an Area of Freedom, Security and Justice”. The project is financed by Torsten and Ragnar Soderberg’s foundations, which have provided Stockholm University with the Torsten and Ragnar Soderberg chair of legal science. During the years 2011–2014, I was the holder of the chair, which entailed that for four years I was free from the responsibilities connected to my ordinary chair. As stated in the preface to the first volume (The Substantive Criminal Law Competence of the EU), this has made it possible for me to devote time to research, which has (this is, of course, an understatement) substantially contributed to the writing of this book. As in the first volume, parts of the book build upon earlier publications. Chapter 4 (Mutual Recognition qua Legal Principle) was written within the framework of this project, but has been published in Festschrift fur Helmut Fuchs (2014). Chapter 7 (Jeopardy on European Level: What is the Question to which the Answer is the EPPO?) was written during the project period, but has been published in the anthology The European Public Prosecutor’s Office—Legal and Criminal Policy Perspectives (2015). In addition, bits and pieces of the text (especially in Chapter 3) draw on previous publications of mine. I have benefitted greatly from being a member of the European Criminal Policy Initiative and of the Commission’s Expert Group on EU Criminal Policy. Equally important has been that I have had the privilege of being a part of the criminal law group at Stockholm University; I have learned a lot from our discussions (on questions relating to both education and research) and I have—this is not less important—had great fun.
