This book provides a detailed legal history of fraud prevention in Europe, from its origins in Roman law through to current EU legislation. Pierre Hauck assesses the development of EU legislative projects that led to the establishment of the PIF Directive, the European Public Prosecutor's Office (EPPO) Regulation and the European Anti-Fraud Office (OLAF) Regulation. Presenting a comparative examination of EU law from the perspectives of individual member states, this book focuses on the history of the three parent legal systems of France, England and Germany. Hauck investigates the close interconnections between the EU's supranational legislation and respective national legal developments, highlighting the ways in which they influence each other. He puts forward a pan-European understanding of fraud on a comparative national basis, contributing to a better understanding of EU law. Fraud in Europe is an indispensable reference for scholars in the field of fraud and for all those involved in the development of fraud laws in Europe, including practitioners at both the supranational EU level and the national level. It is also of great interest to those in the fields of criminal law and justice, European law, corruption and economic crime.
