Supreme Court hears case on Oklahoma's religious charter school: Here's what's at stake

The U.S. Supreme Court heard arguments this week in a case involving St. Isidore of Seville Catholic Virtual School, which could become the first publicly funded religious charter school in the nation — and the outcome could reshape public education across the country.

The case, which has already sparked heated debate in Oklahoma, now has justices on the nation’s highest court weighing the future of public funding for religious schools.

CBS News correspondent Scott McFarlane joined us from Washington to explain what’s at stake.

Arguments lasted a little over two hours, ending just before 11:20 a.m., with a full transcript posted online & Audio Recording

The court's decision is expected on June 25, 2024.

Oklahoma Gov. Kevin Stitt has supported the creation of St. Isidore from the beginning. He is in D.C. on Wednesday to hear the arguments.

Drummond's Lawsuit

Oklahoma’s charter school board approved the proposal, but the state’s Attorney General Gentner Drummond filed a lawsuit against it, saying it violates the separation of church and state.

“This could not be clearer, our Constitution and our statutes say public schools shall be open and free to all and free from sectarian influence. That's what we have. That's what I'm defending,” he said. 

1. The Oklahoma Constitution prohibits public funding benefiting religious institutions, and the Attorney General's office points to Oklahoma law, which states that charter schools are considered public entities. (Article II-Bill of Rights, Section II-5)

Supreme Court Hearing

The Oklahoma Supreme Court agreed with Drummond. Now, the nation’s highest court will have a say, and the decision could set a new standard for how public education and religion mix across the country.

"Oklahoma is leading in education reform, we are leading and turning our education system around, and this will continue to make us that leader, and you'll see other states follow suit - I think it's tremendous for the entire country," said Walters.

Oral arguments are scheduled for Wednesday morning at 9 a.m. CST. A decision likely won’t be made until sometime in the summer. 

What It Could Mean For Oklahoma

If the Supreme Court rules in favor of the Oklahoma Statewide Charter School Board and St. Isidore, it could open the door for more state-funded religious charter schools, not just in Oklahoma but across the country.

While St. Ididore is a Catholic based school, Attorney General Gentner Drummond has argued that the state would be legally obligated to allow charter schools of any religious background to be created and apply for state funding through the charter school board.

All of those schools that receive taxpayer money would still be subject to state law regarding curriculum and accreditation, unlike private schools. How this would integrate with the intent of those institutions to also teach religious material is unclear.

Parent, Faith Leader, and Advocate Response

Parents, faith leaders, and public school advocates rallied in Tulsa with a shared message: Public dollars don't belong in religious classrooms.

Many critics, like Erika Wright of the Oklahoma Rural Schools Coalition, say they fully support the separation of church and state, but now that line is being crossed.

“My kids go to school Monday through Friday, and my expectation as a parent is that when they’re there, they’re focused on learning math and reading… Monday through Friday, school is not Sunday school,” Wright said.

Wright also believes that St. Isidore would be unconstitutional and threaten public school funding.

"The pot of money that is currently funding our brick-and-mortar traditional public schools, those pieces will continue to get smaller and smaller," Wright said.

Tulsa parents like Leslie Briggs say it's not about being anti-religious but about keeping public education secular, inclusive, and fairly funded.

"There are plenty of catholic schools. They've worked for decades," Briggs said. "So to suddenly decide they need to be fully funded by the government is a new and unusual and dangerous approach."

Among those in opposition is Oklahoma Attorney General Gentner Drummond, who filed the original lawsuit in 2023.
