The German Federal Constitutional Court and European Judicial Politics

With its decision on the ratification of the Lisbon Treaty, the German Federal Constitutional Court (FCC) has handed over another landmark ruling on European integration. The ruling made Germany's ratification of the Treaty conditional upon the passage of a new law giving the Bundestag greater oversight of European affairs.

This and the consequences of stronger parliamentary oversight for the German government and the way it conducts negotiations at European level have been the focus of most early comments on the decision.

No less important, however, are the ruling's potential repercussions on European judicial politics. Coming after a series of highly controversial judgments by the European Court of Justice, the FCC's Lisbon decision is clearly meant as a warning to Brussels and, above all, Luxembourg. The decision could undermine the Court of Justice's authority and encourage non-compliance on the part of national courts, thus bringing about a constitutional crisis at European level. Alternatively, the decision may compel the Court of Justice to reconsider some of the most controversial aspects of its activist jurisprudence and to exert more restraint in the foreseeable future.
