The constitutional development of the European Union

Project managers: Göran von Sydow, Anna Wetter and Josefin Almer Wulff

The Lisbon Treaty, which came into force on 1st December 2009, entails a significant number of changes in central areas of EU governance. The Treaty marks the end of a long constitutional process, and introduces changes in the nature of cooperation within a series of policy areas. It is still uncertain, however, what the actual consequences of these changes will be. The question of whether or not the Treaty of Lisbon will be subject to renegotiation has gained new recency since Prime Minister David Cameron announced his intention to hold a British referendum in 2016. The referendum is expected to guide the future of the British EU membership and it can not be ruled out that it will also have effects on the EU constitutional legal order. Since 2003, SIEPS has continuously analysed the constitutional developments in the EU, and aims to continue doing so in 2016.

In 2016, Sieps will also continue its analysis on the practice of the Swedish courts in bringing effect to the EU legal order through the preliminary reference procedure. While the role of the Court of Justice of the European Union is often portrayed as one of the most powerful in the world, Sieps will in a separate publication focus on the interaction between the EU Court and the Member States in the process of preliminary reference procedures.

Another focus of attention relates to the development of the area on EU criminal law and procedure. The area will be highlighted in a couple of publications.
