A higher labor court judge said today that wearing the headscarf wouldn't have led to tension at the school. The plaintiff, who wasn't identified, had appealed an earlier ruling by a court which had rejected her case. City education authorities can appeal the latest ruling.
Berlin has a so-called neutrality law which says teachers, police officers and judicial employees shouldn't wear religious clothes.
But judge Renate Schaude referred to a 2015 ruling by Germany's highest court that general headscarf bans in the western state of North Rhine-Westphalia were infringing religious freedom.
