The Federal Constitutional Court is a characteristic institution of post-war German democracy. The Basic Law accorded it the right to repeal legislation passed as part of the legitimate democratic process should it come to the conclusion that such legislation contravenes the Basic Law. The Constitutional Court only acts in response to petitions. Those entitled to lodge a complaint include the federal bodies Federal President, Bundestag, Bundesrat, Federal Government and their constituent parts – elected representatives or parliamentary parties – as well as federal state governments. In “constitution-related” disputes, the Constitutional Court acts to protect the division of powers guaranteed in the Basic Law and the federal state. In order to enable parliamentary minorities to be able to appeal to the Constitutional Court, one third of the elected representatives of the Bundestag is sufficient to submit a complaint against a valid law (“abstract judicial review”).

Furthermore, the Basic Law empowers individual ciizens to launch a “constitutional complaint” should they feel that the state has infringed their basic rights. Year after year thousands of citizens register a complaint against the constitution. However, the Court reserves the right to select from the mass of petitions submitted only those that can be expected to result in verdicts that point the way ahead in terms of the validity of basic rights. Ultimately every German court is obliged to submit a petition for actual assessment of the normative basis to the Constitutional Court should it consider a law to be un-constitutional. The Federal Constitutional Court holds a monopoly on interpretation of the constitution with regard to all jurisdiction.
