Kampf um Souveränität?

The article documents a panel debate held at the Kiel congress of the German Political Science Association (DVPW) in September 2009. With its Lisbon judgment passed in June 2009, the German Federal Constitutional Court delivered a groundbreaking decision on Germany’s involvement in the European integration process. The Court ruled that the German accompanying law (Begleitgesetz) violated the national constitution because it did not guarantee sufficient parliamentary involvement. Furthermore, the Court announced its intention to intensify the constitutional control of the national applicability of European legal acts (the ultra vires control and the identity control). Stephan Leibfried, Marcus Höreth, Martin Höpner, Fritz W. Scharpf and Michael Zürn discuss the judgment with respect to its implications for the further integration process, for the national and supranational capacities to act, for the democratic quality in the European multilevel system and for political-economic problems.
