What did the U.S. Supreme Court rule in Sloan v. Lemon regarding tuition reimbursement for private schools?

In Sloan v. Lemon, the U.S. Supreme Court struck down the state's tuition reimbursement law as unconstitutional. The case centered around the separation of church and state, particularly in relation to public funding for private education. The Court found that reimbursing parents for tuition at religiously affiliated private schools violated the First Amendment's Establishment Clause, which prohibits the government from promoting or funding religious activities.

This ruling emphasized the importance of maintaining a boundary between governmental support and religious institutions, affirming the principle that public funds should not be used to support religious education. Consequently, it underscored the legal perspective that financial aid or benefits that favor religious schools could be interpreted as an endorsement of religion by the state.
