In March 2010, the authors were both appointed as rapporteurs of the draft Directive of the Council and the European Parliament on the European Protection Order (hereinafter EPO). This initiative was led by the Spanish Presidency, which found enough support within the Member States to activate the new powers conferred by the Lisbon Treaty in criminal matters. This proposal legally emerged from the Stockholm Programme guidelines adopted by the European Council on December 2009, which is a 5-year plan for the EU to settle on a common policy for justice and home affairs, including fundamental rights and the protection of citizens. These guidelines indicate that the area of freedom, security and justice must, above all, be a single area where fundamental rights and freedoms are protected. Moreover, mutual trust between authorities and services in the different Member States is seen as the basis for efficient cooperation in this area and as one of the main challenges in the future. Judicial cooperation in general, especially in criminal matters, is one of the pillars enabling mutual trust and, according to Art. 82(1) of the Treaty on the Functioning of the European Union (TFEU), shall be based on the principle of mutual recognition of judgements and judicial decisions.

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.
