Bridget Mergens was a senior at West side High School in Omaha, Nebraska. She asked her homeroom teacher who was also her principal if she could start a after school Christian club. The school had over thirty clubs already. The principal told her a religious club would be illegal in a public school.
The Supreme Court ruled in favor of Bridget. They said allowing students to meet after school to discuss religion did not require sponsor from the school. The court also ruled that secondary students were responsible enough to meet without a sponsor.
If a school allows clubs that have ties to a class, then it can exclude clubs that are student interest. If the school does have student interest clubs, then they will have to allow religious clubs as well.
