On March 2, 2026, the U.S. Supreme Court ruled 6-3 in Mirabelli v. Bonta, No. 25A810 that California school policies preventing parental notification about children's gender transitions likely violate the Constitution. The per curiam decision restored a statewide injunction and reaffirmed that parents hold fundamental rights over their children's upbringing under both the Free Exercise Clause and the Due Process Clause of the Fourteenth Amendment.

This Ruling Reshapes the Parental Rights Landscape in California
The Supreme Court's 6-3 decision in Mirabelli v. Bonta establishes that state policies interfering with parental access to information about their children face serious constitutional scrutiny. The Court found that California's approach likely violated two independent constitutional provisions, making this a particularly strong statement about the limits of state authority over parent-child relationships.
The per curiam format signals broad agreement among the six justices in the majority. Rather than a single authored opinion that might reflect one justice's particular reasoning, a per curiam decision represents the institutional voice of the Court. For California families navigating divorce and custody disputes, this distinction matters because it suggests the constitutional principle here is settled rather than contested.
The Free Exercise Clause finding is significant because many parents who challenged these policies did so on religious grounds, arguing that concealing information about their children's identity at school directly interfered with their ability to raise their children according to their faith. The Due Process Clause finding reaches further, applying to all parents regardless of religious motivation. Under the Fourteenth Amendment's substantive due process protections, the right of parents to direct the upbringing and education of their children has been recognized since Meyer v. Nebraska, 262 U.S. 390 (1923) and Pierce v. Society of Sisters, 268 U.S. 510 (1925), a lineage spanning over 100 years.
How California Family Law Intersects with This Decision
California family courts already operate under a framework that treats parental rights as fundamental. Under Cal. Fam. Code § 3020, the Legislature has declared that children have the right to frequent and continuing contact with both parents after separation, and that public policy encourages parents to share rights and responsibilities of child-rearing. This ruling reinforces that principle by preventing government institutions from creating information asymmetries between parents and their children.
In custody proceedings, California courts evaluate the best interest of the child under Cal. Fam. Code § 3011, weighing factors including the health, safety, and welfare of the child, any history of abuse, and the nature and amount of contact with both parents. Access to information about a child's school experience, including social transitions, is directly relevant to these determinations. A parent who lacks basic information about their child's daily life at school is at a structural disadvantage in custody proceedings.
California's AB 1955, the SAFETY Act signed into law in July 2024, prohibited school districts from adopting policies requiring parental notification about a student's gender identity. The Mirabelli decision directly impacts the enforceability of this law. While the Supreme Court's injunction addresses the constitutional question, California legislators and school administrators will need to reconcile AB 1955's provisions with the Court's holding that such policies likely violate parents' constitutional rights.
For divorcing parents specifically, the intersection is practical. Under Cal. Fam. Code § 3025, both parents with legal custody are entitled to access their child's school records. The Mirabelli ruling strengthens the argument that this access must include meaningful information about a child's social identity at school, not just grades and attendance records.
How Joint Legal Custody Connects to School Notification
California courts presume joint legal custody under Cal. Fam. Code § 3080. Joint legal custody means both parents share the right and responsibility to make decisions about education, health care, and welfare. When a school withholds information about a child's social transition from one or both parents, it effectively makes a decision that belongs to the parents under California law.
Approximately 80% of California custody orders include joint legal custody arrangements, according to California Judicial Council data. That means the overwhelming majority of separated or divorced parents in California have a legally recognized right to participate in major decisions about their children. The Mirabelli decision reinforces that schools cannot become gatekeepers who decide which parent receives what information.
Practical Takeaways for California Parents
-
Parents with joint legal custody under Cal. Fam. Code § 3083 can request school records and information about their child's social environment at school. This right exists independently of the Mirabelli decision but is now backed by stronger constitutional authority.
-
If you are negotiating a custody agreement, consider including specific provisions about information sharing from schools. Language requiring both parents to be listed as emergency contacts and authorized recipients of all school communications can prevent disputes later.
-
Parents concerned about school notification policies can cite Mirabelli v. Bonta, No. 25A810 (2026) when communicating with school administrators. The statewide injunction applies to all California public schools.
-
If you are in a custody dispute where one parent has withheld school-related information about a child, this ruling provides additional legal support for requesting full disclosure. Courts evaluating best interest under Cal. Fam. Code § 3011 consider whether each parent facilitates the child's relationship with the other parent.
-
Consult a family law attorney before taking legal action based on this ruling. The injunction is in place, but the underlying case may continue to develop as it returns to lower courts for further proceedings.
Frequently Asked Questions
Does the Mirabelli ruling apply only to California?
The Supreme Court's decision in Mirabelli v. Bonta specifically addresses California's policies, but the constitutional principles apply nationwide. The Court's reliance on the Free Exercise Clause and the Fourteenth Amendment Due Process Clause means any state adopting similar notification restrictions could face legal challenges under the same 6-3 framework established on March 2, 2026.
Can my child's school still refuse to share information about a gender transition?
After the March 2, 2026 ruling, California schools cannot enforce policies that affirmatively conceal gender transition information from parents. The statewide injunction restored by the Supreme Court's 6-3 decision blocks these policies while litigation continues. Parents with joint legal custody under Cal. Fam. Code § 3025 retain independent statutory rights to access school records.
How does this affect my custody case?
The Mirabelli decision strengthens arguments that both parents in a joint legal custody arrangement must receive equal access to school information. Under Cal. Fam. Code § 3080, joint legal custody is the presumptive standard in California. Courts evaluating custody modifications will consider whether school notification issues affect the child's best interest under Section 3011.
What if my co-parent and I disagree about how to handle our child's gender identity?
Disagreements about a child's gender identity fall under the joint legal custody framework in Cal. Fam. Code § 3083. When parents cannot agree on a significant decision affecting their child's welfare, either parent can petition the court for a resolution. The Mirabelli ruling ensures both parents have access to the same information, which is a prerequisite for meaningful shared decision-making.
Is AB 1955 (the SAFETY Act) now unconstitutional?
The Supreme Court's 6-3 ruling found that California's parental notification restrictions likely violate the Constitution, but the Mirabelli decision is an injunction, not a final merits ruling. AB 1955, signed in July 2024, remains on the books but its enforcement is blocked by the statewide injunction. The case will return to lower courts, where California must demonstrate its policies survive constitutional scrutiny under both the Free Exercise and Due Process Clauses.
