Over the years the European Union has expanded its legislation in the area of criminal law, criminal procedure and co-operation in criminal matters. This process led to an endless number of framework decisions, directives, regulations and other legal instruments. The fourth edition of Materials on European Criminal Law is a collection of legal instruments including all legal materials relevant for the practice of the Member States of the European Union in one concise volume. It incorporates the most relevant instruments in criminal law, and includes the most recent, such as the Trade and Cooperation Agreement with the United Kingdom. Materials on European Criminal Law in its fourth edition is available both as a hard copy and in electronic format and is useful for practitioners, academics and students alike.
