The notion of constitutional identity and its role in European integration

Since the introduction of Article 4(2) of the Treaty on European Union, the meaning and function of the notion of constitutional identity have become an important point of contention. This study, commissioned by the European Parliament's Policy Department for Citizens' Rights and Constitutional Affairs at the request of the AFCO Committee, examines what the concept of constitutional identity means and how it has been understood in various EU Member States. It assesses the impact of this concept on the relations between the EU and its Member States. Finally, the study evaluates how the notion of constitutional identity can play a role in future EU integration.
