U.S. Supreme Court Opinions

Mirabelli v. Bonta

Docket: 25A810

Opinion Date: March 2, 2026

Areas of Law: Civil Procedure, Civil Rights, Constitutional Law, Education Law

Parents and teachers in California challenged state policies that require schools to keep information about students’ gender transitioning confidential from parents unless the students consent. The parents objected to being excluded from knowledge and decisions regarding their children’s gender presentation at school, especially when those actions conflicted with their religious beliefs or their desire to participate in their children’s mental health care. Several parents described situations in which they were not informed about their children’s gender identity at school until after significant mental health crises occurred. Teachers objected to being compelled to use students’ preferred names and pronouns contrary to the wishes of parents and their own beliefs.

The case was initiated in the United States District Court for the Southern District of California, where two teachers first challenged district policies. As litigation unfolded, the case expanded to include state officials as defendants and parents as additional plaintiffs. The District Court certified parent and teacher classes, granted summary judgment for the plaintiffs, and entered a permanent injunction that prohibited schools from withholding information from parents and required adherence to parental directions on names and pronouns. The District Court also ordered state-created instructional materials to include notice of the rights protected by the injunction.

The United States Court of Appeals for the Ninth Circuit granted a stay of the injunction pending appeal, expressing procedural concerns about class certification under Federal Rule of Civil Procedure 23 and skepticism regarding the merits of the constitutional claims.

The Supreme Court of the United States vacated the Ninth Circuit’s stay as to the parent plaintiffs, concluding that the parents seeking religious exemptions are likely to succeed on their Free Exercise and Due Process claims. The Court found the parents face irreparable harm and that equities favor them. The procedural objections raised by the Ninth Circuit were deemed unlikely to prevail. The application to vacate was otherwise denied.
