The Union faction in the Bundestag unanimously supported a constitutional complaint against the electoral law reform decided by the traffic light coalition.

According to participants at the parliamentary group meeting in Berlin, the MPs would submit an abstract norm control complaint to the Federal Constitutional Court in Karlsruhe to have it checked whether the new electoral law passed by the governing coalition is consistent with the constitution. The parliamentary group will also apply for a temporary injunction.

If the law passed by the traffic light coalition of SPD, Greens and FDP in the past week of meetings comes into force, the proxies of the parliamentary group would file the lawsuit for the MPs, it said. This requires 184 signatures - a quarter of the MPs. There are 197 parliamentarians in the Union faction.

A main thrust of such a control action would be the planned non-allocation of mandates won, the parliamentary manager of the CDU/CSU MPs, Thorsten Frei (CDU), had previously said. According to Frei, this is a violation of the principle of democracy, and citizens are being asked to vote in a sham election. The abolition of the basic mandate clause is also highly problematic from a legal point of view.
