Oklahoma approved St. Isidore of Seville Catholic Virtual School as a public charter school. The Oklahoma Supreme Court blocked the plan. The U.S. Supreme Court split 4-4 after Justice Barrett recused herself, so the state-court ruling remained in place. The decision blocks this Oklahoma school but does not settle the national constitutional question about religious charter schools.
The case centered on whether a privately run charter school is a 'state actor' and if excluding religious groups violates the Free Exercise Clause. The evenly divided affirmance (605 U.S. 165) resolved the specific case without setting a binding nationwide precedent.
Can Oklahoma approve and fund a religious charter school as part of its public charter-school system, or does doing so violate state and federal limits on public religious education?
The judgment of the Oklahoma Supreme Court was affirmed by an equally divided Supreme Court, leaving in place the state-court ruling blocking approval of St. Isidore of Seville Catholic Virtual School as a publicly funded religious charter school.
The immediate effect is that Oklahoma cannot move forward with St. Isidore as a publicly funded religious charter school. The broader national question remains open: whether states must, may, or may not include religious schools in public charter-school programs. That uncertainty matters for religious families, public-school advocates, charter-school systems, and taxpayers because it leaves a major boundary between public education and religious instruction unsettled.
The Court affirmed by an equally divided Court. Justice Barrett did not participate. No opinion explained the Justices' votes.
