OF CALIFORNIA, et al.
on application to vacate interlocutory stay order
No. 25A810. Decided March 2, 2026 Invoking the Free Exercise Clause and Due Process Clause, parents of California public schoolchildren and teachers in the California public school system brought this challenge to a set of statewide student gender policies. Under these policies, school employees must refer to students by their preferred name and pronouns, and school employees must obtain the child's consent before disclosing the child's gender identity to his or her parents. The District Court permanently enjoined enforcement of these policies. The Ninth Circuit stayed the injunction pending appeal. Held: As to the parents, the application to vacate the Ninth Circuit's stay is granted because the stay is not justified under the governing four-factor test. See Alabama Assn. of Realtors v. Department of Health and Human Servs., 594 U. S. 758 (per curiam ). The parents are likely to succeed on the merits of their free exercise claim. California's policies likely trigger strict scrutiny because they substantially interfere with the “right of parents to guide the religious development of their children.” Mahmoud v. Taylor, 606 U. S. 522, 559. The policies likely fail strict scrutiny because they cut out the primary protectors of children's best interests: their parents. The parents who object on due process grounds are also likely to succeed on the merits. Under long-established precedent, parents—not the State—have primary authority with respect to “the upbringing and education of children.” Pierce v. Society of Sisters, 268 U. S. 510, 534–535. The denial of plaintiffs' constitutional rights is irreparable harm. See Roman Catholic Diocese of Brooklyn v. Cuomo , 592 U. S. 14, 19 (per curiam ). And the equities— the most important of which is child safety—favor the parents. Application granted in part and denied in part.

Before us is an application to vacate a Court of Appeals order staying a permanent injunction entered by a District Court on behalf of parents and teachers who claim that certain California policies violate their rights under the Free Exercise Clause of the First Amendment and the Due Proc- Page Proof Pending Publication

I
This case began in the United States District Court for the Southern District of California in 2023 when two teachers sued seeking an exemption from their school district's policies regarding students' gender. During litigation, the school district claimed that state law, as interpreted by the California attorney general and Department of Education, required it to adopt these policies. So the teachers added state officials as defendants, and parents of California school-children joined the lawsuit as plaintiffs. Relying on their own experiences and guidance documents issued by state of-fcials, plaintiffs alleged that California's policies permitted disclosure of a student's gender transitioning at school only if the student consented. Plaintiffs claimed that these policies violated their rights under the Free Exercise Clause of the First Amendment and the Due Process Clause of the Fourteenth Amendment.
Two of the parent plaintiffs, John and Jane Poe, have religious objections to gender transitioning but were not told by their daughter's school when she began to present as a boy and use a male name and male pronouns during her seventh-grade year. In parent-teacher meetings, no one told the Poes about their daughter's transitioning or referred to her using the male name and pronouns that were used at school. At the beginning of their daughter's eighth-grade year, she attempted suicide and was hospitalized. Only then did her parents learn from a doctor that she had gender dysphoria Page Proof Pending Publication
Page Proof Pending Publication
Like the Poes, plaintiffs John and Jane Doe object to gender transitioning, but since fifth grade, their daughter has sometimes identified as a boy. When their daughter was in seventh grade, the Does confronted the school principal about their daughter's transitioning. They believed the school was using a male name and pronouns for their daughter behind their backs. The principal explained that state law prohibited the school from sharing information about a child's transitioning with the child's parents without the child's consent. The Does believed that the risk of leaving their daughter in that school was too great, so they transferred their daughter to a new public school because sending her to a private school was financially and logistically infeasible. The Does have also placed their daughter in therapy.
In 2025, defendants asserted that the guidance documents on which plaintiffs had relied were no longer operative and that the claims against certain state defendants should be dismissed as moot. But the State had promulgated a new required training curriculum that similarly directed teachers not to tell parents about their children's gender identity without the children's consent. Defendants then withdrew their mootness argument, and the District Court declined to impose sanctions.
Later, plaintiffs sought classwide relief, and the District Court certified a class with separate subclasses for parents and teachers. One subclass of parents comprises all those Page Proof Pending Publication
Page Proof Pending Publication
After discovery, the court granted summary judgment for all plaintiffs and entered a permanent injunction in their favor. The injunction prevents the schools from “misleading” parents about their children's gender presentation at school and their social transitioning efforts. Id., at 24a. It also requires the schools to follow parents' directions regarding their children's names and pronouns. And it compels defendants to include in state-created or approved instructional materials a notice of the rights protected by the injunction.
The Ninth Circuit granted defendants' motion to stay the injunction pending appeal. It began by raising procedural objections to the District Court's injunction. It claimed that the District Court had granted class certification without undertaking the “ `rigorous analysis' ” required by Federal Rule of Civil Procedure 23. App. 7a (quoting Wal-Mart Stores, Inc. v. Dukes, 564 U. S. 338, 351 (2011)). And it stated that the injunction appeared to be overly broad because it “covers every parent of California's millions of public school students and every public school employee in the state.” App. 6a. As a result, it opined, the injunction seemed to grant relief to uninjured class members who lacked Article III standing.
The Ninth Circuit also expressed doubts about the District Court's decision on the merits. On the free exercise issue, it relied on a not-precedential Sixth Circuit decision and brushed aside Mahmoud v. Taylor, 606 U. S. 522 (2025), as “a narrow decision focused on uniquely coercive `curricular requirements.' ” App. 10a–11a (citing Doe No. 1 v. Bethel Local School Dist. Bd. of Educ., 2025 WL 2453836, *7 (CA6, Aug. 26, 2025)). The Ninth Circuit expressed skepticism Page Proof Pending Publication

II
When the Ninth Circuit stayed the injunction, the parents and teachers filed this application seeking vacatur of the Ninth Circuit's stay pending appeal.
We grant the application and vacate the stay with respect to the parents because this aspect of the stay is not “justified under the governing four-factor test.” Alabama Assn. of Realtors v. Department of Health and Human Servs., 594 U. S. 758, 763 (2021) (per curiam ) (citing Nken v. Holder, 556 U. S. 418, 434 (2009)).
Likelihood of success on the merits. We conclude that the parents who seek religious exemptions are likely to succeed on the merits of their Free Exercise Clause claim. California's policies likely trigger strict scrutiny under that provision because they substantially interfere with the “right of parents to guide the religious development of their children.” Mahmoud, 606 U. S., at 559 (citing Wisconsin v. Yoder, 406 U. S. 205 (1972)). The parents who assert a free exercise claim have sincere religious beliefs about sex and gender, and they feel a religious obligation to raise their children in accordance with those beliefs. California's policies violate those beliefs and “impos[e] the kind of burden on religious exercise that Yoder found unacceptable.” 606 U. S., at 550. Indeed, the intrusion on parents' free exercise rights here— unconsented facilitation of a child's gender transition—is greater than the introduction of LGBTQ storybooks we considered sufficient to trigger strict scrutiny in Mahmoud. See id., at 563.
California's policies will likely not survive the strict scrutiny that Mahmoud demands. The State argues that its policies advance a compelling interest in student safety and privacy. But those policies cut out the primary protectors Page Proof Pending Publication
Page Proof Pending Publication
The same is true for the subclass of parents who object to those policies on due process grounds. Under long-established precedent, parents—not the State—have primary authority with respect to “the upbringing and education of children.” Pierce v. Society of Sisters, 268 U. S. 510, 534–535 (1925); accord, Meyer v. Nebraska, 262 U. S. 390, 399–400 (1923). The right protected by these precedents includes the right not to be shut out of participation in decisions regarding their children's mental health. Parham v. J. R., 442 U. S. 584, 602 (1979). Gender dysphoria is a condition that has an important bearing on a child's mental health, but when a child exhibits symptoms of gender dysphoria at school, California's policies conceal that information from parents and facilitate a degree of gender transitioning during school hours. These policies likely violate parents' rights to direct the upbringing and education of their children.
Irreparable harm. The denial of plaintiffs' constitutional rights during the potentially protracted appellate process constitutes irreparable harm. Roman Catholic Diocese of Brooklyn v. Cuomo , 592 U. S. 14, 19 (2020) (per curiam ).
Balance of equities. Finally, the “equities do not justify depriving [the parents] of the District Court's judgment in their favor.” Alabama Assn. of Realtors, 594 U. S., at 765. Everyone agrees that children's safety is the overriding equity. And the injunction here promotes child safety by guaranteeing ft parents a role in some of the most consequential decisions in their children's lives. The injunction Page Proof Pending Publication

Concurrence — Barrett J.
The Ninth Circuit's procedural objections to the injunction are unlikely to prevail.
First, the parents protected by the injunction very likely have standing because they are objects of the challenged exclusion policies. See Diamond Alternative Energy, LLC v. EPA, 606 U. S. 100, 114 (2025). Contrary to the Ninth Circuit's suggestion, the injunction does not provide relief for all the parents of California public school students, but only for those parents who object to the challenged policies or seek religious exemptions.
Second, class certification was likely proper. The District Court addressed the requirements for certification under Rule 23 and explained why it concluded that they were met.

The application to vacate the Ninth Circuit's stay presented to Justice Kagan and by her referred to the Court is granted as to the parents but is otherwise denied.
Justice Thomas and Justice Alito would grant the application in full.
Justice Sotomayor would deny the application in full.
Justice Barrett, with whom The Chief Justice and Justice Kavanaugh join, concurring.
As the dissent observes, substantive due process is a controversial doctrine. Judges typically interpret express constitutional rights, such as the freedom of speech or religion. But substantive due process asks us to find unexpressed rights in a constitutional provision that guarantees only “process” before a person is deprived of life, liberty, or property. U. S. Const., Amdt. 14, § 1. When rights are un-Page Proof Pending Publication
Page Proof Pending Publication
The parent-applicants are likely to succeed on the merits under a straightforward application of these cases. California prohibits its public schools from informing parents of their child's gender transition at school unless the child consents. The record in this case indicates that the State's nondisclosure policy applies even if parents expressly ask for information about their child's gender identification. One set of parents learned of their child's transition at school only after the child attempted suicide. Strikingly, even after this tragic event, school administrators continued to withhold information about the student's gender identification. California's nondisclosure policy thus quite obviously excludes parents from highly important decisions about their child's mental health, see Parham, 442 U. S., at 601–604, and is unlikely to satisfy heightened scrutiny. Our resolution of the parents' likelihood of success on this claim is dictated by existing law.
The dissent questions how the Court can adhere to parental-rights precedent after its decision in Dobbs v. Jackson Women's Health Organization, 597 U. S. 215 (2022). Post, at 505 (opinion of Kagan, J.). But Dobbs calls into question neither the doctrine of substantive due process nor the other Page Proof Pending Publication
Page Proof Pending Publication
No party to this dispute questions the continued validity of Meyer , Pierce, or Parham. For all its concerns about de-ciding the issue in this posture, the dissent expresses “no doubt that parents have rights, even though unenumerated, concerning their children and the life choices they make.” Post, at 507. And the precedent recognizing those rights controls our assessment of whether the parents are likely to succeed on the merits.
The word “likely” is important, because it reflects that our assessment is preliminary. We consider the merits not to conclusively resolve them, but because they bear on the limited question before us: Are the parents entitled to the bene-ft of the judgment entered by the District Court while California tries to overturn that judgment on appeal? The Ninth Circuit—itself acting on an interim basis—said “no.” We disagree. The parents must continue to litigate in the Ninth Circuit, and if necessary, this Court. But in the meantime, the injunction of California's policy—which, incidentally, was entered after a full merits process—remains in place.
And contrary to the dissent's charge, granting interim relief is not a sign of the Court's “impatience” to reach the merits. Post, at 503. Instead, the grant reflects the Court's judgment about the risk of irreparable harm to the parents. Page Proof Pending Publication
Page Proof Pending Publication
One last point: The Court has chosen to accompany today's order with a per curiam opinion that explains its reasoning. The choice to say more rather than less is perhaps the source of the dissent's concern that our disposition of this application will be taken as a “conclusive merits judgment.” Post, at 504. But see, e. g., Whole Woman's Health v. Jackson, 594 U. S. –––, ––– (2021) (Kagan, J., dissenting from denial of application for injunctive relief) (critiquing this Court's interim orders for “barely bother[ing] to explain [their] conclusion[s]”); Trump v. Boyle, 606 U. S. –––, ––– (2025) (Kagan, J., dissenting from grant of application for stay) (similar). Interim applications routinely require the Court to balance the lock-in risk of saying too much against the transparency cost of saying too little. See Labrador v. Poe, 601 U. S. 1110, 1128–1129 (2024) (Kavanaugh, J., concurring in grant of stay). In my judgment, the benefits of explanation win out here. The Ninth Circuit (following the Sixth Circuit) significantly misunderstood Mahmoud v. Taylor, 606 U. S. 522 (2025), and general course correction will allow the case to progress efficiently. And because of the Dobbs point that Justice Kagan raises, it would have been unwise to issue an unreasoned order on the parents' substantive due process claim.
When an interim application comes to us, “we must decide it—grant or deny.” Labrador , 601 U. S., at 1121 (Kava-naugh, J., concurring in grant of stay). Because the Nken Page Proof Pending Publication

Dissent — Kagan J.
Justice Kagan, with whom Justice Jackson joins, dissenting.
Today's decision shows, not for the first time, how our emergency docket can malfunction. A case raising novel legal questions and arousing strong views comes to this Court via an application about whether to stay a district court's injunction pending appeal. The ordinary appellate process has barely started; only a district court has ruled on the case's merits. The Court receives scant and, frankly, inadequate briefing about the legal issues in dispute. It does not hold oral argument or deliberate in conference, as regular procedures dictate. It considers the request on a short fuse—a matter of weeks. And then the Court grants relief by means of a terse, tonally dismissive ruling designed to conclusively resolve the dispute. The Court does all this even though the application of existing law to the case raises tricky questions, and so cries out for refection and explanation. The Court is impatient: It already knows what it thinks, and insists on getting everything over quickly. See also, e. g., Department of State v. AIDS Vaccine Advocacy Coalition, 606 U. S. –––, ––– (2025) (Kagan, J., dissenting from grant of stay application); Trump v. Wilcox, 605 U. S. –––, ––– (2025) (Kagan, J., dissenting from grant of stay application).
Indeed, the precipitousness of the Court's decision today has yet a further—and wholly new—dimension: In granting emergency relief, the Court cannot even wait for an appellate court to conclude its own process for deciding the identical issue. As the Court notes, a Ninth Circuit panel last month stayed the District Court's injunction against the challenged policies, pending the State's appeal of that order. See ante, at 495–496. The plaintiffs responded by simultaneously fling two motions—one asking this Court to vacate the panel's Page Proof Pending Publication

And still, there is worse: The Court resolves the issues raised through shortcut procedures on the emergency docket even though it has had—for months now—the option of doing so the regular way, on our merits docket. Since November of last year, a petition for certiorari has been pending in a case that, in critical respects, is a carbon copy of this one. In Foote v. Ludlow School Comm., 128 F. 4th 336 (CA1 2025) (per curiam ), cert. pending, No. 25–77, as here, a public school adopted a policy, conforming to a state agency's guidance, about students who identify as transgender. There, as here, the policy requires school employees to use only a student's preferred name and pronouns, while barring employees from disclosing the student's at-school gender identity to parents. And there, as here, parents challenge that policy as a violation of their right to substantive due process. See id., at 340–344. 1 Why not, then, just grant certiorari in
1 The one difference between this case and Foote is that this case also involves a First Amendment free exercise claim, which would (if successful) give relief to parents with religious objections to the State's pol-Page Proof Pending Publication Page Proof Pending Publication
Certainly, the Court cannot claim that thought and care are not needed. If nothing else, this Court owes it to a sovereign State to avoid throwing over its policies in a slapdash way, if the Court can provide normal procedures. And throwing over a State's policy is what the Court does today. To be sure, the Court sprinkles the word “likely” atop its assessment of which party's arguments will succeed. But no one—in particular, neither a state official nor a lower court—is apt to read the Court's per curiam, brusque though it is, as anything less than a conclusive merits judgment.
In any event, there is something else: This case presents some thorny legal issues. The Court grants relief to parents on the same two substantive grounds that supported the District Court's injunction. First, the Court says, some parents can show that the State's policy “substantially inter-
icy. But as addressed later, the Court's recognition of the substantive due process claim here makes the free exercise claim immaterial. See infra, at 505. That is because accepting the due process claim gives relief to all objecting parents, religious and non-religious alike. So granting certiorari in Foote would allow the Court to consider, on its regular merits docket, the only claim doing actual work here. And if it is nonetheless thought important to address the First Amendment issue as well, the Court could grant certiorari (as I next explain) on one of multiple other cases raising both issues that are likely to reach us in short order.

Anyone remotely familiar with recent debates in constitutional law will understand why: Substantive due process has not been of late in the good graces of this Court—and especially of the Members of today's majority. The Due Process Clause, needless to say, does not expressly grant parental rights of any kind. The relevant text bars a State only from depriving a person of “liberty” “without due process of law.” Members of the majority often have expressed skepticism— sometimes outright hostility—to understanding the “capacious” term “liberty” to enshrine specific rights. Dobbs v. Jackson Women's Health Organization, 597 U. S. 215, 239 Page Proof Pending Publication
Page Proof Pending Publication
None of this is to say that the Court gets the merits here wrong. It may not—as to the plaintiffs' free exercise claim,
2 For that reason, Justice Thomas has called for overruling “all” of this Court's “substantive due process precedents.” Dobbs, 597 U. S., at 332– 333 (concurring opinion). That invitation presumably extends to the precedents supporting both the District Court's decision and today's per cu-riam. See ante, at 497 (citing Meyer v. Nebraska, 262 U. S. 390 (1923); Pierce v. Society of Sisters, 268 U. S. 510 (1925); and Parham v. J. R., 442 U. S. 584 (1979)); App. to Emergency Application 38a–39a.
3 Another contrast—this time, between this case and United States v. Skrmetti, 605 U. S. 495 (2025)—is also striking. In Skrmetti, several parents challenged Tennessee's ban on gender-affirming care for minors. The Page Proof Pending Publication Page Proof Pending Publication
The Court, however, would be far better equipped to draw the appropriate line and to explain its legal basis—in short, to do law in the right way—if it had followed our ordinary processes. A mere decade ago, this Court would never have granted relief in this posture. (Indeed, I am confident that the plaintiffs would never have thought to ask, at this stage, for the Court's involvement.) Then, though apparently not now, we understood that our normal processes—full briefing, oral argument, conference, and opinion writing, along with the time they take—exist for a reason. They ensure that before the Court makes a decision, it has marshaled all the
suit raised claims grounded in both equal protection and substantive due process. As to the latter, the parents in Skrmetti, similarly to the parents here, asserted a right “to make decisions concerning medical care for their minor children.” Pet. for Cert., O. T. 2023, No. 23–466, p. 34; see id., at 18 (invoking a “right of parents with respect to the care, custody, and control of their children, including in decisions about medical care”). And in support of that right, the Skrmetti parents relied on the same precedents the Court does today: Parham, 442 U. S. 584, and Pierce, 268 U. S. 510. See Pet. for Cert., No. 23–466, at 34–36; ante, at 497. But the Court, when deciding to grant certiorari in Skrmetti, limited its review to the equal protection issue: It would not even hear the parents out on their substantive due process claim.
