This book focuses on the enforcement of EU financial law on the national and supra-national levels. Emphasis is laid on the interaction between the EU and national levels (vertical interaction), as well as between the private, administrative, and criminal law levels (horizontal interaction). The book takes a multi-jurisdiction and inter-disciplinary approach and covers a range of issues that are highly topical, such as the new EU Anti-Money Laundering regime, and the ReNEUAL model for administrative law.
