This article focuses on the different implementation solutions of mutual recognition framework decisions, based on a study of the first four framework decisions and their implementation in the Nordic Member States. The Lisbon Treaty changed the environment of EU criminal law and explicitly mentions mutual recognition in Art. 82(1) TFEU. This article also briefly analyses the change towards using either directives or regulations as mutual recognition instruments.Through transformation, the most commonly used form of implementation, the framework decisions are transformed into national legislation and into some of the rules on cooperation in criminal matters in the respective national legal systems. Transformation entails modifying other relevant national legislation to correspond with the implementing national legislation.

The budget of the EU for 2010 amounted to over €140 billion, a sum greater than the national budget of 20 of the 27 Member States of the Union for the same year. Such a large amount of money calls for sound financial management and presents a significant risk of fraud and corruption. The European Anti-Fraud Office (OLAF) is the body tasked with safeguarding the financial interests of the EU. Established in 1999 by a Commission Decision, its main task is to fight illegal activities that could have a detrimental effect upon the EU budget. Although formally a part of the Commission, OLAF enjoys full independence when conducting investigations. It must be noted, however, that in practicing its independence, the Office is accountable to a number of EU bodies. OLAF’s accountability can be of a disciplinary, political, auditable, administrative, and judicial nature.
