It s the students decision. The invocation can t be unrestricted and prayer at football games is not allowed. 3 rd Circuit Students can t take a poll to decide if they will have prayer at graduation. 9 th Circuit Student council can t select a member of the student body to recite a prayer before a school assembly during the school day.

The school left it up to the students to select volunteers to deliver the invocation and did not monitor the religious speech. This had the effect of advancing religion. Unrestricted student-led messages at graduation ceremonies also violated the Establishment Clause. In 1993, the Alabama legislature enacted a statute permitting religious speech in its public schools. The district court determined that the statute was unconstitutional and issued a permanent injunction.
