sentences:  In September 2003, the German Federal Constitutional Court ("Bundesverfassungsgericht") ruled that the states could ban the wearing of Islamic headscarves by female teachers, and that this would not infringe the constitutional protection of freedom of religion.However, a ban could only be implemented by a state law, and not by administrative decisions.In one incident involving Islamic dress in Germany, two 18-year-old students, one Turkish and one Kurdish, appeared at a school in Bonn in a burqa; they were suspended for "disturbing the peace."
