On the surface, Santa Fe Independent School District v. Doe (2000) rose out of fairly mundane circumstances to become a defining moment in jurisprudence involving prayer and public schools. Santa Fe is a rural district in southeastern Texas, not far from Galveston. They typically began home football games with prayer, and included similar expressions of faith during graduation. A Mormon family and a Catholic family complained, and the case worked its way up to the Supreme Court.
The school modified its policies along the way so that students first voted on whether or not to have an opening prayer at games, and when they voted 'yes' (there was never really any doubt about that part) they’d cast ballots to see who would lead it. The district hoped this would make the prayer a student-driven activity and insulate it from constitutional challenges. It didn’t.
