Three final remarks suffice. First, both chambers of the German parliament have approved the Lisbon Treaty and have therefore made use of what the Federal Constitutional Court has deemed in its Maastricht judgment a key means of ensuring a democratic character of the Union and of Germany's membership in it.
Second, much of the academic literature, as well as an empirical inquiry recently conducted at Utrecht University, have shown that the Bundestag, unlike the Bundesrat, is quite passive in using the available tools of influencing Union's policies and laws.
Third, the outcome of the pending Lisbon Treaty cases is of prime importance not only for Germany but for the whole of the EU and its relevance transcends the remaining ratification procedures in Ireland, Poland and the Czech Republic. This is not least because the "sale of the state's vital powers" is at stake, as Prof. Klaus Buchner one of the complainants said.
It has all the ingredients to become the most influential pronouncement that the German Federal Constitutional Court has ever made regarding the EU.
