Bradley Little, Governor of Idaho, et al., Petitioners v. Lindsay Hecox, et al.

The Supreme Court heard arguments in a fight over Idaho's Fairness in Women's Sports Act, which bars transgender girls and women from female sports teams at public schools and universities. The case asks whether the Equal Protection Clause lets a state require athletes to compete based on biological sex rather than gender identity.

The case was argued on January 13, 2026, and the Court has not ruled yet. Idaho says the Constitution allows its categorical sports rule, while Hecox argues that ban violates the Equal Protection Clause.

The case could affect school and college sports rules for transgender students across the country. For example, it will matter to athletes like Lindsay Hecox, who wanted to run on Boise State's women's cross-country team.

The case asks whether Idaho can require school athletes to compete based on biological sex. Hecox says that rule unlawfully excludes transgender girls and women.

Students, colleges, and school sports programs could all be affected. The decision could shape who may join female teams at public schools and universities.

The Supreme Court has already heard argument. The main next step is a written decision, likely by late June or early July unless the schedule changes.
