Schoolgirl is allowed to wear Niqab despite ban
For three years now, a 16-year-old student from Belm (Landkreis Osnabrück) has been coming to school fully covered. This is actually forbidden.
However, no punitive measures were taken against the girl and her parents so far, the school tolerated the concealment. Now the religion committee of the state parliament has interfered and decided: the young woman is allowed to wear her niqab, which leaves only a slot for the eyes.
They did not want to force her to remove the veil, explained State Secretary Erika Huxhold. And this despite the fact that the pupil was violating the Lower Saxony laws, the Lower Saxony constitution, and the Basic Law.
16-year-old gets involved in the lessons

The reason: According to statements of all involved, the school peace is not endangered by the full veiled 16-year-old, explained Huxhold. There had been no complaints from classmates, teachers or parents during the entire time. In addition, the student was also taking part in class. The school is still compulsory for the 16-year-old and she’s going to graduate from high school next year. The well-being of the girl was in the foreground, she said.
Headmistress tried to prevent the full covering
The headmaster of the Highschool in Belm had tried for a long time to persuade the girl and her family to give the veil up – but without success. Only when she became aware of the case of an 18-year-old student from Osnabrück, who also came to school with a Niqab in August, she turned to the Lower Saxony school authorities. In the case of the 18-year-old, the Osnabrück administrative court had forbidden participation in lessons with Niqab.
The Lower Saxony school authority had also commented on the process in Osnabrück. An official spokeswoman had declared that the state could not fulfill its educational task with disguised pupils. They said that open communication, which included the spoken word mimic and body language, were not possible with a face veil.
Is Belm the precedent?
According to the “Hannoversche Allgemeine Zeitung”, four other cases are known in the country, in which minor pupils had worn a Niqab. They could be convinced through conversations, to remove it. According to HAZ, the CDU [Christian Democrtic Party]fears that Belm could become a precedent. Stefan Politze (SPD) [Socialists], on the other hand, praised the committee’s thoughtful, leveled action “of the best interest of the children”.
