Mahmoud v. Taylor
Does the Free Exercise Clause of the First Amendment require a public school district to provide religious opt-outs from a mandatory curriculum involving storybooks with LGBTQ themes, and does a policy eliminating previously available opt-outs trigger strict scrutiny?

Majority Opinion— John G. Roberts Jr.concurring ↓dissent ↓
In a 6–3 decision authored by Chief Justice John G. Roberts Jr., the Supreme Court reversed the Fourth Circuit and ruled in favor of the parents. The Court held that the Montgomery County Board of Education's policy of eliminating religious opt-outs from the LGBTQ-inclusive storybook curriculum triggered strict scrutiny under the Free Exercise Clause and that the policy could not survive that scrutiny.
The majority reasoned that the no-opt-out policy was not neutral and generally applicable because the school district maintained a system of individualized exemptions from other curriculum materials for a variety of secular reasons. Under the framework established in Fulton v. City of Philadelphia (2021) and Church of the Lukumi Babalu Aye v. City of Hialeah (1993), when a government creates a mechanism for granting individualized exemptions but refuses to extend comparable exemptions for religious exercise, the policy is not generally applicable and must satisfy strict scrutiny. The Court found that MCPS could not demonstrate that its refusal to allow religious opt-outs was narrowly tailored to achieve a compelling government interest.
Critically, the majority determined that remanding the case to the lower courts to apply the correct standard was unnecessary. Because the factual record was sufficiently developed and the lower courts had only erred on the legal standard of review—not on factual findings—the Court applied strict scrutiny directly. The Court emphasized that the school district had operated the same curriculum with opt-outs for months without any demonstrated harm to its educational objectives, fatally undermining any claim that a blanket no-opt-out policy was the least restrictive means of achieving the district's goals.
The majority was careful to note that the decision did not grant parents a general veto over public school curricula. Rather, the holding was grounded in the specific circumstances of this case: a system that already provided for individualized exemptions yet categorically refused them for religious objectors, combined with the district's inability to show that the opt-out ban was necessary to accomplish its educational mission.
Concurring Opinions
Justice Amy Coney Barrett wrote a concurrence joined by Justice Brett Kavanaugh emphasizing the narrowness of the holding, stressing that the decision turned on the specific finding that MCPS operated a system of individualized exemptions while categorically denying them for religious reasons, and that the ruling should not be read as establishing a broad parental right to opt out of any curriculum content that conflicts with religious beliefs.
Dissenting Opinions

The dissent argued that the majority fundamentally mischaracterized a routine curriculum decision as a burden on religious exercise and that the decision threatens the ability of public schools to fulfill their core educational mission. Justice Sotomayor contended that exposure to information about the existence of diverse families is not a burden on anyone's religious practice and that the Constitution does not entitle parents to a religious exemption from every public school lesson they find objectionable.
- Public schools have long been understood to have broad authority over curricular decisions, and the Free Exercise Clause has never been interpreted to give individual parents the right to carve out religious exceptions from the general academic program
- The majority's comparison of secular curriculum adjustments (such as medical or accessibility accommodations) to religious opt-outs from substantive content is a false equivalence that distorts the individualized-exemption framework beyond recognition
- The practical consequence of the decision is to give any parent with a sincere religious objection a potential constitutional right to withdraw their child from curriculum content, which will chill schools from teaching about a wide range of topics and disproportionately harm LGBTQ students who see their families reflected in the classroom
- The Court should not have applied strict scrutiny in the first instance but should have remanded to allow the lower courts to develop the record and assess the school district's justifications under the correct standard
Background & Facts
In 2023, Montgomery County Public Schools (MCPS) in Maryland introduced a collection of storybooks with LGBTQ-inclusive themes—such as books depicting same-sex couples and gender-nonconforming characters—into the English Language Arts curriculum for pre-kindergarten through eighth-grade students. When the books were first introduced, the district allowed parents to opt their children out of lessons involving those titles if the content conflicted with the family's values or beliefs. However, within months, MCPS reversed course and eliminated the opt-out policy entirely, requiring all students to participate in lessons featuring the books regardless of parental objections.
A coalition of parents from multiple religious backgrounds—including Muslim, Christian, and Jewish families—filed suit. The lead plaintiff, Lubna Mahmoud, a Muslim mother, argued that forcing her young children to sit through classroom readings of material that directly contradicted her family's deeply held religious beliefs about marriage, sexuality, and gender placed a substantial burden on her free exercise of religion. The defendants were members of the Montgomery County Board of Education, with the case styled against board member Taylor.
The parents sought a preliminary injunction that would restore the opt-out policy while the case was litigated. The U.S. District Court for the District of Maryland denied the injunction, finding that the school curriculum was a neutral, generally applicable policy that did not implicate strict scrutiny under the Free Exercise Clause. On appeal, the U.S. Court of Appeals for the Fourth Circuit affirmed in a divided 2–1 decision, applying rational basis review and concluding that the parents had not shown a likelihood of success on the merits.
The Supreme Court granted certiorari, recognizing the significant and recurring question of when public school curriculum policies trigger heightened judicial scrutiny under the Free Exercise Clause. The case drew enormous public attention and a large number of amicus briefs from religious organizations, civil liberties groups, educators, and state governments on both sides.
The Arguments
The school district's elimination of religious opt-outs from curriculum materials that directly contradict parents' sincerely held religious beliefs imposes a substantial burden on their free exercise of religion. Because the policy is neither neutral nor generally applicable—given that MCPS grants other types of individualized exemptions from curriculum requirements—strict scrutiny applies and the policy cannot survive it.
- The school district previously allowed opt-outs, proving that accommodating religious families was feasible and did not disrupt the educational program
- MCPS continues to grant individualized exemptions from other curriculum materials for various secular and medical reasons, making the no-opt-out rule for these particular books neither neutral nor generally applicable under the framework of Fulton v. City of Philadelphia
- The government cannot show that denying religious opt-outs is narrowly tailored to serve a compelling interest, especially when it previously operated the same curriculum with opt-outs in place
The school district's curriculum is a neutral, generally applicable educational policy that does not target religious practice. Parents do not have a constitutional right to dictate or selectively exempt their children from the public school curriculum, and rational basis review is the appropriate standard.
- The storybooks are part of a broad, secular educational mission to promote literacy and teach children about the diversity of families in their communities, not to suppress any religious viewpoint
- No student is asked to affirm or adopt any belief—parents remain free to teach their own values at home, and exposure to diverse perspectives is a core function of public education
- Granting religious opt-outs from disfavored curriculum topics would undermine schools' ability to maintain a coherent educational environment and could open the door to limitless exemption requests
