More than two dozen families have asked the U.S. Supreme Court to strike down a Texas law requiring the Ten Commandments in public school classrooms, setting up a potential landmark fight over religion, parental rights, and constitutional precedent.
The families, representing multiple faiths and school districts across Texas, filed their petition on August 17, 2026, seeking review of two Fifth Circuit Court of Appeals rulings that upheld Senate Bill 10. Governor Greg Abbott signed the law in 2025, and parents challenged it almost immediately. A federal district judge blocked it. Then Texas Attorney General Ken Paxton fought back, and the Fifth Circuit ruled 9-8 in favor of the state.
Now the question lands where it was always headed: the Supreme Court. And the petitioners face a legal landscape that has shifted dramatically against them in recent years.
The families' core argument rests on Stone v. Graham, a 1980 Supreme Court decision that struck down a nearly identical Kentucky law. That ruling held that posting the Ten Commandments in classrooms served "no secular legislative purpose" and violated the First Amendment. For more than four decades, Stone stood as a wall against such displays.
But the wall developed a crack in 2022. In Kennedy v. Bremerton School District, the case of a high school football coach who prayed on the 50-yard line, the Supreme Court formally eliminated the so-called Lemon test, a framework courts had used since the early 1970s to evaluate Establishment Clause challenges. Stone v. Graham relied heavily on that test.
The Fifth Circuit saw the opening and drove through it. In Nathan v. Alamo Heights ISD, the appeals court ruled that with the Lemon test gone, Stone "no longer had a leg to stand on." The opinion, issued April 21, 2026, reversed U.S. District Judge Fred Biery's preliminary injunction against the law. A companion case, Cribbs Ringer v. Comal ISD, reached the same result.
The ruling was authored by Judge Kyle Duncan of Louisiana and grounded in originalist legal reasoning, National Review reported. Legal analyst Andrea Picciotti-Bayer described the decision in striking terms:
"The Ten Commandments have been carved in stone for millennia. Now, thanks to a landmark en banc ruling by the United States Court of Appeals for the Fifth Circuit, they may finally be safe from the chisels of separationist litigants."
The 9-8 margin was decisive for an en banc panel, meaning the full circuit weighed in, not just a three-judge panel. That distinction matters. En banc decisions carry more weight and signal that the court considered the issue significant enough to hear with all active judges participating.
The cert petition, filed with the Supreme Court and hosted by Americans United for Separation of Church and State, makes an argument that borrows heavily from language conservatives have championed in other contexts: parental rights in public education.
The petition contends that S.B. 10 mandates a specifically Protestant version of the Ten Commandments, and that displaying it as authoritative classroom text sends a message to students of other faiths, or no faith, that their families' beliefs are wrong. The petition's language is pointed:
"A Protestant version of the Ten Commandments is presented as the authoritative set of classroom religious rules to be followed, and it conveys to students who do not adhere to this scripture that the religious beliefs and practices instilled by their parents are incorrect and sinful."
The petitioners also cite the Supreme Court's own recent majority opinion in Kennedy v. Bremerton, which acknowledged that religious instruction in public schools, where students are a "captive audience," is "problematically coercive" and implicates a "foremost" historical hallmark of religious establishment. In other words, the families are trying to use the same ruling that undermined Stone to argue that the Texas law still crosses a constitutional line.
And they invoke Mahmoud v. Taylor, a case involving parents who sued to opt out of school reading materials they found religiously objectionable. A lower court had dismissed the parents' concerns, ruling that exposure to "religiously offensive ideas" did not amount to a government-imposed burden on religious exercise. The Supreme Court majority rejected that reasoning. Justice Samuel Alito, in a retort to the dissent, captured the stakes plainly:
"According to the dissent, parents who send their children to public school must endure any instruction that falls short of direct compulsion or coercion and must try to counteract that teaching at home."
That line cuts both ways. Alito wrote it to defend parental objections to progressive curriculum. The Texas petitioners now want the Court to apply the same principle to a state-mandated religious display. The Supreme Court has shown a willingness to engage in sharp internal debate on questions of government power and individual rights, and this case could produce another such clash.
Texas officials have not been shy about celebrating the Fifth Circuit's decision. Attorney General Ken Paxton framed the ruling in moral terms.
As the Washington Examiner reported, Paxton declared it "a major victory for Texas and our moral values." In separate remarks carried by the AP, Paxton said the Ten Commandments "have had a profound impact on our nation, and it's important that students learn from them every single day."
Jonathan Saenz, president of Texas Values, went further, calling the ruling "one of the most important religious liberty victories for Texas in our glorious history."
The ACLU and its co-plaintiffs, meanwhile, have made clear they intend to fight. A joint statement from the ACLU and the plaintiff coalition said they "anticipate asking the Supreme Court to reverse this decision." The statement argued that the First Amendment "safeguards the separation of church and state, and the freedom of families to choose how, when and if to provide their children with religious instruction," and that the Fifth Circuit's ruling "tramples those rights."
The cert petition asks the justices to settle a question the petitioners say only the Supreme Court can answer: whether Stone v. Graham remains binding precedent. The families argue that only the Supreme Court itself, not a lower court, can overturn its own decisions, and that the Fifth Circuit overstepped by treating Stone as effectively dead.
The Fifth Circuit's ruling does not affect Texas alone. AP News reported that the decision bolsters similar laws in Louisiana and Arkansas. If the Supreme Court declines to take the case, or takes it and upholds the Fifth Circuit, states across the country could move to enact their own Ten Commandments display requirements with confidence that the legal ground has shifted in their favor.
The original lower court injunction had blocked the law in about a dozen Texas school districts. The Fifth Circuit's reversal cleared the way for S.B. 10 to take effect statewide, requiring displays in all public school classrooms beginning in the 2025-2026 school year.
The Supreme Court has a busy docket of culturally significant cases. The justices are already weighing landmark rulings on gun rights and transgender athlete bans, and other petitions involving religious liberty and cultural flashpoints continue to arrive, including a case in which a Korean spa asked the Court to protect its female-only policy from a state transgender mandate.
Whether the justices grant certiorari in the Texas Ten Commandments case remains to be seen. The petition was filed August 17, 2026, and as of publication, the Court had not acted on it. But the petitioners face a difficult reality: the legal framework they depend on, the Lemon test, was dismantled by the very Court they are now asking for help.
The families' argument has a certain symmetry that could appeal to justices on both sides of the ideological divide. Parental rights in education have become a rallying cry for conservatives, from school board fights over curriculum to congressional demands for transparency after major Court rulings. The Texas petitioners are asking the Court to extend that same principle to parents who object to state-mandated religious content.
But the argument cuts against itself. The petition leans on Mahmoud v. Taylor and Justice Alito's defense of parents who objected to progressive instruction. Alito's reasoning was aimed at protecting families from a school system that dismissed their religious concerns. Applying it to block a law that promotes religious content in classrooms requires the Court to treat parental objections to religion in schools the same way it treats parental objections to secular ideology, a move that could create tensions the current majority may not want to invite.
The Fifth Circuit, for its part, has been described as the nation's most conservative appellate court. It has also been reversed by the Supreme Court more times than any other circuit for three consecutive years. That track record gives the petitioners a sliver of hope, but it also reflects a circuit that has pushed legal boundaries the current Court may ultimately endorse.
The cert petition argues that the Court has shown "a long line of concern for the Establishment Clause rights of public school children." That is true. But the Court's recent trajectory, eliminating the Lemon test, defending a praying football coach, and siding with parents who objected to progressive materials, suggests the justices are far more interested in protecting religious expression than in policing it.
The families challenging S.B. 10 deserve a hearing. Every parent has a stake in what the state puts on a classroom wall. But the legal ground beneath their feet was reshaped by the same Court they now petition, and asking nine justices to reverse a shift they themselves set in motion is a long walk uphill.
