“Leave the matter of religion to the family altar, the church, and the private school, supported entirely by private contributions.” Ulysses Grant. Petitioners challenged a scholarship program that required enrollment in a “charter school” and admission to a qualified private school. Taxpayer money funded the scholarship, which was paid to the parents who then paid the private school. Nearly 93% of recipients enrolled in religious schools. The Court held the program unconstitutional under Colorado’s expansive prohibition on public funding of “sectarian” schools because the program “supports and sustains” such schools. The element of private choice was insufficient absent safeguards against funding religious schools. As such, invalidating the program does not violate the 1st Amendment. Petitioners lacked taxpayer standing to challenge the program under a statute.
