The U.S. Supreme Court ruled 4-4 on Thursday, blocking Oklahoma's attempt to establish the nation’s first taxpayer-funded religious charter school, St. Isidore of Seville Catholic Virtual School. This tie leaves in place a lower court's ruling that determined the school violated constitutional guidelines surrounding the separation of church and state, according to HuffPost and NPR.

The court's decision stems from an application approved by the Oklahoma Statewide Charter School Board to create a charter school that would incorporate Catholic teachings into its curriculum. This arrangement was viewed as conflicting with both state and federal laws that demand charter schools be nonsectarian, according to ABC News, CBS News, and Los Angeles Times.

Justice Amy Coney Barrett's recusal was a significant factor in the ruling's tie, as she has connections to the legal advocacy surrounding the case. The Supreme Court's brief decision did not elaborate on individual justices' positions, but the case is seen as a crucial test of the First Amendment's religion clauses, according to New York Times and Reuters.

This outcome represents a setback for advocates pushing for religious charter schools in Oklahoma and could have broader implications for similar cases in other states. The case was closely watched amid increased movement from conservative factions advocating for religious involvement in public education, according to BBC and Newsweek.
