This event marks the launch of Professor Jacob Öberg's book "The Normative Foundations for EU Criminal Justice: Powers, Limits and Justifications ". Should the European Union regulate criminal justice? The book explores the question forensically, establishing whether a compelling normative justification for EU action in the field exists. The book seeks to develop an integrated theoretical framework based on the perspectives of the effective allocation of regulatory authority between the EU and the Member States, representation-based political theories, and harm-based theories of criminal law.
