A midwestern school district approved a policy allowing open access to its facilities by the public as long as public use did not interfere with school activities. The community has a history of deep religious convictions. A group of graduating seniors and their parents arranged for a baccalaureate ceremony sponsored by the community. The ceremony was to be held in a school gymnasium. Verbal authorization was granted by school district officials. One month later, the district approved a new policy, which prohibited the group from using the gym.
