In June the court ruled [JURIST report] that the German Bundestag has the right to be heard on the European financial crisis, holding in a case initiated by the Green party that Chancellor Angela Merkel failed to notify the parliament early enough about plans for the ESM regarding its sister party in Austria. Although that decision did not have any effect on the 500 billion euro ESM, it increased the parliament's rights by requiring the chancellor's government to provide notice to the parliament as early as possible in the future. A previous ruling that gave the parliament similar rights over matters concerning the EU was issued in February. The country's constitutional court held [JURIST report] that the use of a parliamentary subcommittee to fast-track decisions related to eurozone bailouts is unconstitutional, instead requiring the entire Bundestag to overview such decisions. In September the court ruled [JURIST report] that the parliament did not unconstitutionally impair its own ability to adopt and control the nation's budget, nor did it infringe on the budget autonomy of future parliaments.
