Book excerpt: EU criminal law is one of the fastest evolving, but also challenging, policy areas and fields of law. This Handbook provides a comprehensive and advanced analysis of EU criminal law as a structurally and constitutionally unique policy area and field of research. With contributions from leading experts, focusing on their respective fields of research, the book is preoccupied with defining cross-border or ‘Euro-crimes’, while allowing Member States to sanction criminal behaviour through mutual cooperation. It contains a web of institutions, agencies and external liaisons, which ensure the protection of EU citizens from serious crime, while protecting the fundamental rights of suspects and criminals. Students and scholars of EU criminal law will benefit from the comprehensive research present in this Handbook. National and EU policy-makers, as well as judges, defence lawyers and human rights lawyers will find the analysis of current legal action, combined with proposed solutions, useful to their work
