The ultra-conservative Muslim group around German Salafist convert Sven Lau sparked public outrage with their vigilante patrols in the western city of Wuppertal in 2014, but prosecutors have struggled to build a case against them.
The city’s district court ruled that the seven accused members of the group did not breach a ban on political uniforms when they approached people while wearing orange vests bearing the words “Sharia Police”.
Judges said there could only be a violation of the law – originally aimed against street movements such as the early Nazi party – if the uniforms were “suggestively militant or intimidating”, a court spokesman said.
In this case, they found that the vests were not threatening and noted that one witness said he thought the men were part of a bachelor party.
The same court had already thrown out the case last year, but was overruled on appeal by a higher court which agreed with prosecutors that the ban on uniforms could be applied in this case.
