This book provides answers to the following questions. Is there a bright future ahead for a European Public Prosecutor Office? If so, is the regulation establishing the office sufficiently clear and balanced to attain that goal? Moreover, will the office be able to effectively fight fraud now damaging the EUs budget and will it respect the fundamental rights of the parties involved? Included are issues ranging from EU substantive and procedural criminal law, combatting EU fraud, the distribution of competences in European law enforcement, EU fundamental rights, to forum choice. The books aim is to inform academics, policy-makers and criminal law practitioners about key issues surrounding the attribution of prosecutorial powers to an entirely remodelled European Union body. In doing so, it sheds light on this body, as fundamentally changed bythe Council, which will undoubtedly have a greater impact on the European criminal justice system than the European Arrest Warrant ever did.
