Mirabelli v. Bonta
Mirabelli v. Bonta, No. 25A810 (U.S. Mar. 2, 2026)
Posture: Application to vacate an interlocutory stay order entered by the Ninth Circuit staying a district court’s permanent injunction.
Factual and Procedural Background
The case arose from challenges by parents and teachers to certain California policies (as plaintiffs described them and as reflected in state-issued guidance and training materials) concerning students’ efforts to socially transition at school. The parents alleged that the policies prevent schools from informing parents about their children’s gender transitioning at school unless the child consents, and that schools must use children’s preferred names and pronouns regardless of parental wishes. The teacher plaintiffs objected to compelled participation in implementing the policies.
The litigation began in 2023 in the U.S. District Court for the Southern District of California when two teachers sued seeking an exemption from their school district’s gender-related student policies. During litigation, the school district asserted state law (as interpreted by the California Attorney General and Department of Education) required the policies; the teachers then added state officials as defendants, and parents joined as plaintiffs.
The opinion describes experiences of two sets of parent plaintiffs. John and Jane Poe alleged they were not informed that their daughter began presenting as a boy and using a male name and pronouns at school; they learned of gender dysphoria only after a suicide attempt and hospitalization, and later alleged school officials continued using male name and pronouns contrary to parental instructions. John and Jane Doe alleged that a principal explained state law prohibited disclosure of a child’s transitioning without the child’s consent; they transferred their daughter to a different public school and placed her in therapy.
In 2025, defendants asserted certain guidance documents were no longer operative and argued that claims against some state defendants were moot; after California promulgated a new required training curriculum that similarly directed teachers not to tell parents about a child’s gender identity without the child’s consent, defendants withdrew the mootness argument, and the district court declined to impose sanctions.
The district court certified a class with separate subclasses for parents and teachers (including subclasses for those objecting to the policies and those seeking religious exemptions). After discovery, the district court granted summary judgment for all plaintiffs and entered a permanent injunction. The injunction (as described in the opinion) prevents schools from “misleading” parents about children’s gender presentation and social transitioning efforts, requires schools to follow parents’ directions regarding children’s names and pronouns, and compels inclusion of a notice of rights protected by the injunction in state-created or approved instructional materials.
The Ninth Circuit stayed the permanent injunction pending appeal, raising procedural concerns (including class certification and breadth/standing) and expressing doubts about plaintiffs’ merits claims. Plaintiffs then filed this application seeking vacatur of the Ninth Circuit’s stay.
Legal Issues Presented
- Whether the Ninth Circuit’s stay of the district court’s permanent injunction was justified under the governing four-factor test for a stay pending appeal.
- Whether the parent plaintiffs seeking religious exemptions were likely to succeed on their Free Exercise Clause claim (including whether California’s policies likely trigger strict scrutiny and can survive it).
- Whether the parent plaintiffs were likely to succeed on their Fourteenth Amendment due process claim relating to parental authority over upbringing, education, and participation in mental-health decisions.
- Whether the parents faced irreparable harm absent relief, and whether the balance of equities favored vacating the stay as to the parents.
- Whether the Ninth Circuit’s procedural objections (including standing concerns and Rule 23 class certification concerns) were likely to prevail.
Arguments of the Parties
Plaintiffs’ (Parents’ and Teachers’) Position (as reflected in the opinion)
- The challenged California policies prevent schools from telling parents about their children’s efforts to engage in gender transitioning at school unless the children consent to parental notification.
- The policies require schools to use children’s preferred names and pronouns regardless of parental wishes.
- Parents alleged violations of the Free Exercise Clause and the Due Process Clause.
- Teachers objected to compelled participation in implementing the challenged policies.
Defendants’ Position (as reflected in the opinion)
- Defendants argued in 2025 that earlier guidance documents relied on by plaintiffs were no longer operative and that claims against certain state defendants should be dismissed as moot; defendants later withdrew the mootness argument after a new required training curriculum was promulgated.
- In opposing the free exercise claim at the stay stage, the State argued its policies advance a compelling interest in student safety and privacy.

| Precedent | Rule or Principle Cited For | Application by the Court |
|---|---|---|
| Wal-Mart Stores, Inc. v. Dukes, 564 U. S. 338, 351 (2011) | Rule 23 requires a “rigorous analysis” for class certification. | Quoted by the Ninth Circuit in stating that the district court allegedly failed to conduct the required rigorous analysis. |
| Mahmoud v. Taylor, 606 U. S. 522 (2025) | (1) Parents’ right to guide the religious development of their children; (2) a burden on religious exercise sufficient to trigger strict scrutiny; (3) used as a comparator for the level of intrusion (LGBTQ storybooks in a curriculum context). | The Court relied on Mahmoud to conclude the religious-exemption parents were likely to succeed on free exercise and that strict scrutiny likely applies; it found the intrusion here greater than what triggered strict scrutiny in Mahmoud. Justice Barrett stated the Ninth Circuit misunderstood Mahmoud. The Ninth Circuit characterized Mahmoud as narrow and uniquely coercive (as described by the per curiam). |
| Doe No. 1 v. Bethel Local School Dist. Bd. of Educ., 2025 WL 2453836, *7 (CA6, Aug. 26, 2025) | Cited by the Ninth Circuit (as described) in addressing the free exercise issue and in its characterization of Mahmoud. | The per curiam noted the Ninth Circuit relied on this not-precedential Sixth Circuit decision and brushed aside Mahmoud. |
| Alabama Assn. of Realtors v. Department of Health and Human Servs., 594 U. S. 758, 763 (2021) (per curiam) | Stay relief must be justified under the governing four-factor test; cites Nken. | The Court held the Ninth Circuit’s stay was not justified under the four-factor test as to the parents; also cited for the equities analysis that the equities did not justify depriving parents of the district court’s judgment. |
| Nken v. Holder, 556 U. S. 418, 434 (2009) | Source of the governing four-factor test for stays pending appeal. | Used as the governing standard; Justice Barrett also cited Nken for the irreparable-harm principle in the interim-relief analysis. |
| Wisconsin v. Yoder, 406 U. S. 205 (1972) | Substantial interference with parents’ right to guide their children’s religious development; unacceptable burdens on religious exercise in the parental context. | The Court concluded California’s policies impose a burden akin to what Yoder found unacceptable, supporting likely success and strict scrutiny under the Free Exercise Clause. |
| Troxel v. Granville, 530 U. S. 57, 68-69 (2000) (plurality opinion) | Parents as primary protectors of children’s best interests. | Invoked to rebut the State’s asserted compelling interests by emphasizing that California’s policies “cut out” parents. |

S. 510, 534-535 (1925) | Parents have primary authority over the upbringing and education of children. | Used to support likelihood of success on the parents’ due process claim; also cited in Justice Barrett’s concurrence and Justice Kagan’s dissent as parental-rights precedent. |
| Meyer v. Nebraska, 262 U. S. 390, 399-400 (1923) | Parents’ authority over upbringing and education of children. | Used alongside Pierce to support likelihood of success on due process; also cited by Justice Barrett and Justice Kagan. |
| Parham v. J. R., 442 U. S. 584, 602 (1979) | Parental right includes participation in decisions regarding children’s mental health. | Applied to conclude the nondisclosure and facilitation policies likely violate parents’ due process rights; emphasized again in Justice Barrett’s concurrence and discussed in Justice Kagan’s dissent. |
| Roman Catholic Diocese of Brooklyn v. Cuomo, 592 U. S. 14, 19 (2020) (per curiam) | Denial of constitutional rights during potentially protracted appellate proceedings constitutes irreparable harm. | Used to find irreparable harm to the parents if the stay remained in place during appeal. |
| Diamond Alternative Energy, LLC v. EPA, 606 U. S. 100, 114 (2025) | Standing principle: plaintiffs have standing when they are objects of challenged policies. | Used to reject the Ninth Circuit’s standing concerns as unlikely to prevail, concluding the protected parents likely have standing as objects of the exclusion policies. |
| Washington v. Glucksberg, 521 U. S. 702, 721 (1997) | Test for recognizing unexpressed rights: “deeply rooted in this Nation’s history and tradition” and “implicit in the concept of ordered liberty.” | Justice Barrett cited it as the demanding test used to mitigate risks in substantive due process adjudication and to frame how parental rights fit within that doctrine. |

| McDonald v. Chicago, 561 U. S. 742, 811 (2010) (THOMAS, J., concurring in part and concurring in judgment) | Quoted critique of substantive due process as a “particularly dangerous” “legal fiction” inviting judges to act on personal views. | Justice Kagan cited it to illustrate the majority’s stated skepticism toward substantive due process. |
| Obergefell v. Hodges, 576 U. S. 644, 721 (2015) (THOMAS, J., dissenting) | Further cited critique of substantive due process. | Justice Kagan cited it as part of the dissent’s discussion of the Court’s recent substantive due process debates. |
| Sessions v. Dimaya, 584 U. S. 148, 191 (2018) (GORSUCH, J., concurring in part and concurring in judgment) | Quoted concern about judicial misuse of the “so-called ‘substantive component’ of due process” to dictate policy. | Justice Kagan cited it as another example of skepticism toward substantive due process. |
| United States v. Skrmetti, 605 U. S. 495 (2025) | Discussed as a comparison regarding the Court’s treatment of substantive due process claims involving parents and medical care for minors. | Justice Kagan cited it to note that in Skrmetti the Court limited review to equal protection rather than hearing a substantive due process claim asserted by parents. |
Court's Reasoning and Analysis
The Court applied the “governing four-factor test” for a stay pending appeal (citing Alabama Assn. of Realtors and Nken) and held the Ninth Circuit’s stay was not justified as to the parents.
Likelihood of success (parents—Free Exercise): The Court concluded that parents seeking religious exemptions were likely to succeed on their Free Exercise Clause claim because California’s policies likely trigger strict scrutiny by substantially interfering with “the right of parents to guide the religious development of their children” (citing Mahmoud and Yoder). The Court found the policies impose an unacceptable burden on religious exercise and described the intrusion—unconsented facilitation of a child’s gender transition—as greater than the curricular exposure at issue in Mahmoud. The Court then found the policies were likely not narrowly tailored even assuming compelling interests in student safety and privacy, reasoning that the policies “cut out” parents and that safety interests could be served by allowing religious exemptions while restricting disclosure to parents who would engage in abuse.
Likelihood of success (parents—Due Process): The Court also found likely success for the subclass of parents objecting on due process grounds. Relying on Pierce and Meyer, it reiterated that parents have primary authority over “the upbringing and education of children,” and relying on Parham, it stated that this includes the right not to be shut out of decisions regarding children’s mental health. The Court reasoned that gender dysphoria bears importantly on a child’s mental health, but that California’s policies conceal relevant information from parents and facilitate social transitioning at school, likely violating parental rights.
Irreparable harm: The Court held that denial of the parents’ constitutional rights during a potentially protracted appeal constitutes irreparable harm (citing Roman Catholic Diocese of Brooklyn).
Balance of equities: The Court concluded equities favored the parents, emphasizing that children’s safety is the overriding equity and that the injunction promotes safety by guaranteeing fit parents a role in consequential decisions. It added that the State may still protect children from unfit parents through child-abuse laws and removal from custody where appropriate (citing Alabama Assn. of Realtors).
Procedural objections (standing and class certification): The Court found the Ninth Circuit’s procedural objections unlikely to prevail. It reasoned the parents likely have standing as objects of the challenged exclusion policies (citing Diamond Alternative Energy), and rejected the Ninth Circuit’s characterization of the injunction as benefiting all parents statewide, stating it covers only those who object or seek religious exemptions. It also stated class certification was likely proper because the district court addressed Rule 23 requirements and explained why they were met (with the opinion indicating omissions in the quoted discussion).
Separate writings: Justice Barrett (joined by the Chief Justice and Justice Kavanaugh) concurred, emphasizing the need for a demanding approach to unenumerated rights under substantive due process (citing Glucksberg) while concluding existing parental-rights precedent likely controls; she also addressed the dissent’s reliance on Dobbs and explained why Dobbs does not undermine parental-rights cases. Justice Kagan (joined by Justice Jackson) dissented, criticizing the Court’s emergency-docket process, objecting to the Court preempting the Ninth Circuit’s en banc consideration, and arguing the issues should be resolved through the Court’s regular merits docket (discussing Foote and other matters). The dissent also discussed the controversy around substantive due process and cited multiple opinions critical of that doctrine.
Holding and Implications
Holding: The application to vacate the Ninth Circuit’s stay is GRANTED as to the parents and OTHERWISE DENIED. The Court vacated the stay with respect to the parents, leaving the district court’s permanent injunction in effect as to them while the appeal proceeds; the application was denied in other respects (including as to the teachers).
Implications: As a direct effect, the parents covered by the class/subclasses described in the opinion are entitled to the benefit of the district court’s injunction during the Ninth Circuit appeal. The Court’s order does not finally resolve the merits; it addresses interim stay relief and emphasizes likelihood-of-success and irreparable-harm considerations. Justice Thomas and Justice Alito would have granted the application in full, while Justice Sotomayor would have denied it in full.

SUPREME COURT OF THE UNITED STATES
No. 25A810 ELIZABETH MIRABELLI, ET AL. v. ROB BONTA,
ATTORNEY GENERAL OF CALIFORNIA, ET AL.
ON APPLICATION TO VACATE INTERLOCUTORY STAY ORDER
[March 2, 2026]
PER CURIAM.
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 cer- tain California policies violate their rights under the Free Exercise Clause of the First Amendment and the Due Pro- cess Clause of the Fourteenth Amendment. The parents object that these policies prevent schools from telling them about their children's efforts to engage in gender transition- ing at school unless the children consent to parental notifi- cation. The parents also take issue with California's re- quirement that schools use children's preferred names and pronouns regardless of their parents' wishes. The teachers object to their compelled participation in the implementa- tion of the State's policies.
I
This case began in the United States District Court for the Southern District of California in 2023 when two teach- ers 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 schoolchildren joined the lawsuit as plaintiffs. Relying on
1
2 MIRABELLI v. BONTA Per Curiam
their own experiences and guidance documents issued by state officials, 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 re- ligious 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 re- ferred 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 and had been presenting as a boy at school. Just months after being discharged, the Poes' daughter was rehospitalized and held there involuntarily because she was at risk for self-harm. At a new school in ninth grade, she once again began identifying as a boy. Contrary to the Poes' instructions, teachers and school offi- cials continued to use a male name and pronouns for their daughter, citing their obligations under California state law. The Poes have placed their daughter in therapy and obtained psychiatric care for her.
Like the Poes, plaintiffs John and Jane Doe object to gen- der 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
2
3 Cite as: 607 U. S. ____ (2026) Per Curiam
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 be- cause 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 docu- ments on which plaintiffs had relied were no longer opera- tive and that the claims against certain state defendants should be dismissed as moot. But the State had promul- gated a new required training curriculum that similarly di- rected 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 who object to the challenged policies, while a separate sub- class is limited to those who seek a religious exemption. App. to Emergency Application 90a (App.). Two similar subclasses of teachers were also certified. Id., at 89a-90a. After discovery, the court granted summary judgment for all plaintiffs and entered a permanent injunction in their favor. The injunction prevents the schools from "mislead- ing" 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 re- garding their children's names and pronouns. And it com- pels defendants to include in state-created or approved in- structional 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
3
4 MIRABELLI v. BONTA Per Curiam
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 be- cause it "covers every parent of California's millions of pub- lic 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 Dis- trict 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 about the parents' and teachers' Fourteenth Amendment due process claim because it viewed those claims as seeking to expand the protection afforded by es- tablished precedent.
When the Ninth Circuit stayed the injunction, the par- ents and teachers filed this application seeking vacatur of the Ninth Circuit's stay pending appeal.
II
We grant the application and vacate the stay with respect to the parents because this aspect of the stay is not "justi- fied 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. Califor- nia's policies likely trigger strict scrutiny under that
4
5 Cite as: 607 U. S. ____ (2026) Per Curiam
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 poli- cies 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 sto- rybooks we considered sufficient to trigger strict scrutiny in Mahmoud. See id., at 563.
California's policies will likely not survive the strict scru- tiny 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 of children's best interests: their parents. See Troxel v. Granville, 530 U. S. 57, 68-69 (2000) (plurality opinion). California's policies also appear to fail the narrow-tailoring requirement. The State's interest in safety could be served by a policy that allows religious exemptions while preclud- ing gender-identity disclosure to parents who would engage in abuse. For these reasons, the parents who object to the California policies on free exercise grounds are likely to suc- ceed on the merits.
The same is true for the subclass of parents who object to those policies on due process grounds. Under long-estab- lished 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 in- cludes the right not to be shut out of participation in deci- sions regarding their children's mental health. Parham v.
5
6 MIRABELLI v. BONTA Per Curiam
J. R., 442 U. S. 584, 602 (1979). Gender dysphoria is a con- dition that has an important bearing on a child's mental health, but when a child exhibits symptoms of gender dys- phoria at school, California's policies conceal that infor- mation from parents and facilitate a degree of gender tran- sitioning 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 eq- uity. And the injunction here promotes child safety by guaranteeing fit parents a role in some of the most conse- quential decisions in their children's lives. The injunction also permits the State to shield children from unfit parents by enforcing child-abuse laws and removing children from parental custody in appropriate cases.
III
The Ninth Circuit's procedural objections to the injunc- tion 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 pre- sented to J USTICE KAGAN and by her referred to the Court is granted as to the parents but is otherwise denied. J USTICE THOMAS and JUSTICE ALITO would grant the ap- plication in full.
J USTICE SOTOMAYOR would deny the application in full.

SUPREME COURT OF THE UNITED STATES
No. 25A810 ELIZABETH MIRABELLI, ET AL. v. ROB BONTA,
ATTORNEY GENERAL OF CALIFORNIA, ET AL.
ON APPLICATION TO VACATE INTERLOCUTORY STAY ORDER
[March 2, 2026]
JUSTICE BARRETT, with whom THE CHIEF JUSTICE and J USTICE KAVANAUGH join, concurring. As the dissent observes, substantive due process is a con- troversial doctrine. Judges typically interpret express con- stitutional 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 prop- erty. U. S. Const., Amdt. 14, §1. When rights are unstated, how do judges know what they are? The obvious risk is that judges will use their own values as a guide, thereby jeop- ardizing the People's right to self-governance. To mitigate this risk, the Court has crafted a demanding test for recog- nizing unexpressed rights: They must be "deeply rooted in this Nation's history and tradition" and "implicit in the con- cept of ordered liberty." Washington v. Glucksberg, 521 U. S. 702, 721 (1997) (internal quotation marks omitted). Relevant here, the doctrine of substantive due process has long embraced a parent's right to raise her child, which in- cludes the right to participate in significant decisions about her child's mental health. See Pierce v. Society of Sisters,
268 U. S. 510 (1925); Meyer v. Nebraska, 262 U. S. 390 (1923); Parham v. J. R., 442 U. S. 584 (1979). The parent-applicants are likely to succeed on the merits under a straightforward application of these cases. Califor- nia prohibits its public schools from informing parents of
8
2 MIRABELLI v. BONTA B ARRETT, J., concurring their child's gender transition at school unless the child con- sents. The record in this case indicates that the State's non- disclosure 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 af- ter this tragic event, school administrators continued to withhold information about the student's gender identifica- tion. 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 res- olution 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 5-6 (opinion of K AGAN, J.). But Dobbs calls into question neither the doctrine of substantive due pro- cess nor the other unexpressed rights that the doctrine pro- tects. Applying Glucksberg, Dobbs holds that Roe v. Wade,
410 U. S. 113 (1973), and Planned Parenthood of Southeast- ern Pa. v. Casey, 505 U. S. 833 (1992), were incorrectly de- cided because a right to abortion is not " 'deeply rooted in this Nation's history and tradition' and 'implicit in the con- cept of ordered liberty.' " Dobbs, 597 U. S., at 231. And be- cause the Court concluded that the stare decisis factors counseled against retaining these cases, Dobbs overruled them. Id., at 263-290. It does not follow from Dobbs that all our substantive due process cases conflict with Glucks- berg, much less that stare decisis would counsel overruling any that do.
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
9
3 Cite as: 607 U. S. ____ (2026) B ARRETT, J., concurring unenumerated, concerning their children and the life choices they make." Post, at 6. And the precedent recog- nizing 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 benefit 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, in- cidentally, was entered after a full merits process—remains in place.
And contrary to the dissent's charge, granting interim re- lief is not a sign of the Court's "impatience" to reach the merits. Post, at 2. Instead, the grant reflects the Court's judgment about the risk of irreparable harm to the parents. See Nken v. Holder, 556 U. S. 418, 435 (2009). If the par- ents were probably right but would suffer little harm from the Ninth Circuit's stay, they would not be entitled to in- terim relief. Ibid. But that is not the situation here. Under California's policy, parents will be excluded—perhaps for years—from participating in consequential decisions about their child's mental health and wellbeing. Thus, the par- ents are likely to suffer irreparable harm if California en- forces its policy while this litigation winds its way through the courts. Ante, at 6.
One last point: The Court has chosen to accompany to- day's order with a per curiam opinion that explains its rea- soning. 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 judg- ment." Post, at 4. But see, e.g., Whole Woman's Health v.

S. ___, ___ (2025) (K AGAN, J., dissenting from grant of application for stay) (slip op., at 3) (similar). In- terim 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. ___, ___-___ (2024) (K AVANAUGH, J., concurring in grant of stay) (slip op., at 11-12). In my judgment, the benefits of expla- nation 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 al- low the case to progress efficiently. And because of the Dobbs point that J USTICE KAGAN raises, it would have been unwise to issue an unreasoned order on the parents' sub- stantive due process claim.
When an interim application comes to us, "we must de- cide it—grant or deny." Labrador, 601 U. S., at ___ (K AVANAUGH, J., concurring in grant of stay) (slip op., at 2). Because the Nken factors strongly favor the parents, ante, at 4-6, I see no basis for denying this application.

SUPREME COURT OF THE UNITED STATES
No. 25A810 ELIZABETH MIRABELLI, ET AL. v. ROB BONTA,
ATTORNEY GENERAL OF CALIFORNIA, ET AL.
ON APPLICATION TO VACATE INTERLOCUTORY STAY ORDER
[March 2, 2026]
JUSTICE KAGAN, with whom JUSTICE JACKSON joins, dis- senting.
Today's decision shows, not for the first time, how our emergency docket can malfunction. A case raising novel le- gal 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, inad- equate briefing about the legal issues in dispute. It does not hold oral argument or deliberate in conference, as reg- ular 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 reflection 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 Advo- cacy Coalition, 606 U. S. ___, ___ (2025) (K AGAN, J., dissent- ing from grant of stay application) (slip op., at 2-3); Trump
v. Wilcox, 605 U. S. ___, ___ (2025) (K AGAN, J., dissenting from grant of stay application) (slip op., at 2-3, 8). Indeed, the precipitousness of the Court's decision today has yet a further—and wholly new—dimension: In granting
12
2 MIRABELLI v. BONTA K AGAN, J., dissenting emergency relief, the Court cannot even wait for an appel- late court to conclude its own process for deciding the iden- tical 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 or- der. See ante, at 3-4. The plaintiffs responded by simulta- neously filing two motions—one asking this Court to vacate the panel's stay and the other asking the Ninth Circuit to do the same thing through en banc review. The Ninth Cir- cuit is already acting on the motion filed there: The court promptly called for (and has now received) a response from the State, preparatory to exchanging memoranda and vot- ing on reconsideration of the panel's decision. Regular or- der counsels that, in this situation, the Ninth Circuit should go first. The lower court, that is, should decide whether to vacate the stay; and only then should this Court decide whether further action is needed. Cf. Supreme Court Rule
23.3 (Stay applications "shall set out with particularity why the relief sought is not available from any other court"). But the Court's impatience cannot be contained for even that long. The Court jumps the line, pre-empting the Ninth Cir- cuit's normal (and notably reflective) en banc process. Why wait for appellate procedures to play out when the Court already knows what it wants?
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 em- ployees to use only a student's preferred name and
13

pronouns, while barring employees from disclosing the stu- dent'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 340-344.1Why not, then, just grant certiorari in Foote, and decide it this coming fall? Or if there is some reason that Foote is not suitable, the Court could take one of the many cases lined up behind it. By recent count, almost 40 cases raising due process and/or free exercise objections to similar school pol- icies are currently in the judicial system (with several re- cently decided by appellate courts), so this Court would not have to wait long. See Pet. for Cert. in Foote, O. T. 2025, No. 25-77, p. 32. By granting certiorari on one (or more) of those cases, the Court could ensure that the issues raised by such policies receive the careful, disciplined considera- tion they merit, rather than the inevitably truncated review the Court affords emergency applications.
Certainly, the Court cannot claim that thought and care are not needed. If nothing else, this Court owes it to a sov- ereign 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 ——————

The one difference between this case and Foote is that this case also involves a First Amendment free exercise claim, which would (if success- ful) give relief to parents with religious objections to the State's policy. But as addressed later, the Court's recognition of the substantive due process claim here makes the free exercise claim immaterial. See infra, at 4. That is because accepting the due process claim gives relief to all objecting parents, religious and non-religious alike. So granting certio- rari 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.
14
4 MIRABELLI v. BONTA K AGAN, J., dissenting court—is apt to read the Court's per curiam, brusque though it is, as anything less than a conclusive merits judg- ment.
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 par- ents can show that the State's policy "substantially inter- fere[s]" with their First Amendment right "to guide the re- ligious development of their children." Ante, at 5. Here, the Court analogizes to Mahmoud v. Taylor, 606 U. S. 522 (2025), a decision issued last Term about school curriculum. The ink on that decision is barely dry, and courts have just begun to consider its meaning and reach. But even assume the Court is right on the free exercise score; still, that could not justify extending relief to all the parents here. After all, some of those parents object to the State's policy not for re- ligious reasons, but simply because it prevents them from taking part in their children's most crucial life decisions. So the District Court also ruled on substantive due process grounds, finding a parental right to "direct the upbringing and medical care of their children." App. to Emergency Ap- plication 54a. And indeed, in doing so, the court made its free exercise ruling superfluous, because the due process ground protects every parent, whether or not religious. See supra, at 3, n. 1. This Court, to affirm the relief given, must follow the same course: It explains that the State's policy
"excludes parents" from "participation in decisions regard- ing their children's mental health." Ante, at 5-6. But the very phrasing the Court uses betrays the delicateness of the operation: Even in recognizing that parental right, the Court cannot quite bring itself to name the legal doctrine— it is, again, substantive due process—that provides the right's only basis.
Anyone remotely familiar with recent debates in consti- tutional 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 Pro- cess Clause, needless to say, does not expressly grant pa- rental rights of any kind. The relevant text bars a State only from depriving a person of "liberty" "without due pro- cess of law." Members of the majority often have expressed skepticism—sometimes outright hostility—to understand- ing the "capacious" term "liberty" to enshrine specific rights. Dobbs v. Jackson Women's Health Organization,
597 U. S. 215, 239 (2022). Substantive due process, one has stated, is a "particularly dangerous" "legal fiction" because it "invites judges" to "roa[m] at large in the constitutional field guided only by their personal views." McDonald v. Chicago, 561 U. S. 742, 811 (2010) (T HOMAS, J., concurring in part and concurring in judgment); Obergefell v. Hodges,
576 U. S. 644, 721 (2015) (T HOMAS, J., dissenting).2An- other has pointed to the "judicial misuse of the so-called 'substantive component' of due process to dictate policy on matters that belonged to the people to decide." Sessions v. Dimaya, 584 U. S. 148, 191 (2018) (G ORSUCH, J., concurring in part and concurring in judgment). And yet a third, when defending the Court's elimination of a 50-year-old right grounded in substantive due process, explained that the
"Constitution does not grant the nine unelected Members of this Court the unilateral authority to rewrite the Constitu- tion." Dobbs, 597 U. S., at 340 (K AVANAUGH, J., concur- ring). There are many such statements to choose from in this Court's recent substantive due process caselaw. Espe- cially given the Court's last venture into the field, today's ——————

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 curiam. See ante, at 5-6 (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.

6 MIRABELLI v. BONTA K AGAN, J., dissenting decision cannot but induce a strong sense of whiplash. Compare ante, at 5-6 (recognizing a parent's right to make important decisions about her child's health), with Dobbs,
597 U. S., at 231 (repudiating a woman's right to make im- portant decisions about her own health).3 None of this is to say that the Court gets the merits here wrong. It may not—as to the plaintiffs' free exercise claim, or their substantive due process claim, or both. As to due process particularly—because, again, that claim alone does all the load-bearing work in this case, see supra, at 3, n. 1, 4—I have no doubt that parents have rights, even though unenumerated, concerning their children and the life choices they make. See Pierce v. Society of Sisters, 268 U. S. 510, 534-535 (1925); Parham v. J. R., 442 U. S. 584, 602- 603 (1979). On the other side of ledger, of course, a State has critical interests in the care and education of children. But California's policy, in depriving all parents of infor- mation critical to their children's health and well-being, could have crossed the constitutional line. And that would entitle the parents, at the end of the day, to relief. 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 ——————

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 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, cus- tody, 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 5-6. But the Court, when deciding to grant certiorari in Skrmetti, lim- ited its review to the equal protection issue: It would not even hear the parents out on their substantive due process claim.

ordinary processes. A mere decade ago, this Court would never have granted relief in this posture. (Indeed, I am con- fident 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 pro- cesses—full briefing, oral argument, conference, and opin- ion writing, along with the time they take—exist for a rea- son. They ensure that before the Court makes a decision, it has marshaled all the relevant facts; considered all inter- ested parties' and multiple lower courts' legal arguments; and deliberated internally, with full understanding of each other's perspectives, on all disputed issues. So too, those processes enable us to think through the best legal ra- tionale for, and scope of, any decision, given both the views we have earlier expressed and the related issues that will soon come before us. And they allow us to explain ourselves well and carefully, both to the parties and to the public. Our processes are, in short, the hallmark of judicial probity, and alike its guarantor. There was no reason to abandon them here. I respectfully dissent.
