Core of State Sovereignty and Boundaries of European Union's Identity in the Lissabon – Urteil

In the 2009 judgment dealing with the Treaty of Lisbon, the German Federal Constitutional Court urges to modify a domestic statute in order to guarantee the rights of the internal rule-making power and also provides a reasoning on the role of the European Union (EU) as an international organization, the principle of sovereignty and the relations between European Institutions and Bodies and the EU Member States. According to the German Court the Treaty of Lisbon does not transform the European Union into a Federal State (Staatsverband), but into a Confederation of States (Staatenverbund). In spite of the 1993 landmark judgment, the so-called “Maastricht Urteil”, the Court steps forward and focuses also the subject-matters that necessarily have to pertain to the Member States jurisdiction, the so-called “domain reserve”. The German Federal Constitutional Court decision on the Lisbon Treaty arouses the reflection on the core of State sovereignty and on the boundaries of the EU legal system and focuses on the force of the right to vote of every citizen, the basis of democracy.Furthermore, the decision of the German Federal Constitutional Court highlights the well-known issue of the EU's identity and the balancing between EU democracy and Member State sovereignty. In the light of the German Constitutional Court statements, the present work aims to understand which could be actually the EU's identity and how could be approached “democratic deficit” of the EU.
