University officials said Tuesday that the Muslim Student Union can take its case to the chancellor if its appeal is rejected. The suspension would go into effect Sept. 1.

The university revoked the group’s charter for a year and placed it on probation for another year.

Eleven students were arrested in February for disrupting the ambassador’s speech, which prompted an investigation by the university into the group’s activities.

The group’s attorney says the punishment will affect hundreds of Muslims who regularly attend prayer meetings and socialize together.
