WASHINGTON (Reuters) - The U.S. Supreme Court on Thursday blocked a bid led by two Catholic dioceses to establish in Oklahoma the nation’s first taxpayer-funded religious charter school in a major case involving religious rights in American education.

The 4-4 ruling left intact a lower court’s decision that blocked the establishment of St. Isidore of Seville Catholic Virtual School. The lower court found that the proposed school would violate the U.S. Constitution’s First Amendment limits on government involvement in religion.

Conservative Justice Amy Coney Barrett recused herself from the Oklahoma case. Barrett is a former professor at Notre Dame Law School, which represents the school’s organizers.
