This book aims to present a coherent picture of the influence of Union law on national criminal law and criminal procedure. It also sketches the contours of the emerging criminal justice system of the Union. European criminal law is explained as a multi-level field of law, in which the Union has a normative influence on substantive criminal law, criminal procedure and on the co-operation between Member States. In the future, this might be supplemented by a European Public Prosecutor's Office, through which the European Union would enforce criminal law directly.

The book is written for criminal lawyers and European lawyers, as well as practitioners, academics and students of European criminal law. It sets out to allow the reader to assess the mutual (and sometimes conflicting) influence of Union law and national criminal law respectively. The book explains how Union law will usually prevail, although national criminal law still remains relevant.
