Draft AfD ban proposal submitted to German Parliament.

Die AfD soll durch das Bundesverfassungsgericht überprüft werden - so will es der Entwurf für einen Verbotsantrag mehrerer Abgeordneter. Er liegt nun dem Bundestag vor.

Couldn't find any English source. Main relevance, politically, being that now the Bundestag will have to discuss it, and they will have to vote on it, one way or the other, no more ducking away.
Only the constitutional court can ban parties, and only the Bundestag, Bundesrat, and the government can ask the constitutional court to do so.
