Statement of the Czech President Václav Klaus on the procedure

In Germany the Federal Constitutional Court had to decide on several constitutional complaints against the Lisbon Treaty and its accompanying law.
The hearing of the Second Senate of the German Federal Constitutional Court took place on 10. and 11. February 2009. The judgement was delivered on 30. June 2009. On the one hand the Federal Constitutional Court declared the Lisbon Treaty to be compatible with the German Basic Law. On the other hand, it stated that Germany's approval in the EU Council of legal instruments of the EU in various policy fields are subject to a prior approving act by the Bundestag (parliament) and Bundesrat (federal council). Regarding a particvipation of the German armed forces in a European initiative the Federal Constitutional Court clarified that the German government may act in this field only upon the order of the German Bundestag.
