An evenly divided Supreme Court on Thursday upheld a lower court decision that invalidated a contract approved by the Oklahoma Statewide Charter School Board that established the nation’s first religious charter school, blocking the effort in a closely watched case that posed a test for the separation of church and state.

The high court split 4-4, which leaves in place the decision of the Oklahoma Supreme Court. Justice Amy Coney Barrett did not participate in the case. The high court issued a one line, unsigned decision stating “the judgment is affirmed by an equally divided court.”
