The U.S. Supreme Court ruled 6-3 on Tuesday that states may bar biological males from competing on girls’ and women’s sports teams in public schools and universities, upholding laws in Idaho and West Virginia and clearing the way for similar restrictions in more than two dozen other states.
The consolidated decisions in West Virginia v. B.P.J. and Little v. Hecox mark a major victory for efforts to preserve sex-based categories in scholastic athletics. The Court held that such classifications do not violate Title IX of the Education Amendments of 1972 or the Equal Protection Clause of the 14th Amendment when they are based on biological sex.
History and Background
Idaho enacted the Fairness in Women’s Sports Act in 2020, the first state law of its kind, requiring participation on female teams to be determined by biological sex at birth. West Virginia passed its Save Women’s Sports Act in 2021 with similar provisions.
Lower courts had split on the challenges brought by “transgender” students Lindsay Hecox in Idaho and B.P.J. (Becky Pepper-Jackson) in West Virginia, as previously reported on by The Dallas Express. The 9th Circuit blocked Idaho’s law, while the 4th Circuit found West Virginia’s law violated Title IX in B.P.J.’s case.
The Supreme Court granted certiorari in 2025 after its ruling in United States v. Skrmetti, which upheld Tennessee’s restrictions on sex-altering procedures for minors. Oral arguments occurred on January 13, 2026, with conservative justices signaling strong support for the states’ positions during more than three hours of debate.
In the majority opinion released June 30, 2026, the Court affirmed that schools may maintain women’s and girls’ sports teams for biological females. It emphasized that biological sex determines eligibility to ensure fairness and opportunity.
The three left-wing justices dissented in part. Justice Sonia Sotomayor, joined by Justices Elena Kagan and Ketanji Brown Jackson, wrote in a partial dissent that the ruling fails to account for individuals who have undergone medical interventions.
Impact and What it Means
The decision means public schools and universities in states with these laws — and potentially others — can require athletes to compete based on their biological sex rather than self-identified gender. Biological males (“transgender” girls or women) are excluded from girls’ and women’s teams, regardless of hormone treatments or identification.
This applies across K-12 and collegiate levels in affected programs.
The ruling does not immediately ban participation nationwide but validates state authority to enforce biological-sex categories. It is expected to affect the 27 states with similar laws already on the books. Enforcement details will vary by state, with many laws already providing for verification processes when disputes arise.
Supreme Court merits decisions are self-executing and take effect upon release.
