In a decisive 6-3 ruling on June 30, 2026, the U.S. Supreme Court upheld West Virginia’s and Idaho’s laws protecting women’s and girls’ sports teams for biological females. The Court held that Title IX permits schools to maintain separate teams based on biological sex and that such classifications do not violate the Equal Protection Clause of the Fourteenth Amendment.
Justice Kavanaugh, writing for the majority (joined by Chief Justice Roberts and Justices Thomas, Alito, Gorsuch, and Barrett), reaffirmed that “sex” in Title IX refers to biological sex — the ordinary meaning at the time of the law’s enactment in 1972. The decision recognizes the inherent physical differences between males and females that make sex-segregated sports necessary for fair competition and safety. Twenty-seven states have passed similar protections in recent years, and the Court rightly declined to force schools to ignore biology in the name of gender identity.
The plaintiffs — biological males identifying as female — argued for exceptions based on puberty blockers or hormones. The Court rejected this, noting that legislatures and schools are better equipped to handle the science and fairness issues than judges conducting individualized comparisons. The ruling also dismissed attempts to import Title VII/Bostock reasoning into the sports context, where competitive equity demands different considerations.
This outcome is a strong rebuke to activist courts and the Biden-era interpretations that tried to rewrite Title IX to erase sex-based distinctions. It protects female athletes from having their opportunities, scholarships, and safety compromised by biological males in their categories — a common-sense position long championed by parents, female athletes, and conservatives who refuse to let ideology trump reality.
The dissenters predictably sided with redefining sex, but the majority stood firm on biology, fairness, and the original intent of Title IX: advancing opportunities for women, not undermining them. A clear win for common sense and the rule of law.
