The Supreme Court held that Title IX permits schools to keep girls’ and women’s sports teams limited to students classified as female based on biological sex, and that West Virginia’s policy did not violate the Equal Protection Clause. The Court reversed the Fourth Circuit, ruling for West Virginia and Idaho in the jointly decided cases.

- Reversed
Impact
Students seeking to play on girls’ or women’s school teams are directly affected. Schools may limit those teams to biological females under Title IX. For example, West Virginia may require a transgender girl to compete on boys’ or co-ed teams. The ruling lets states determine female-team eligibility using biological sex alone. It also holds such policies satisfy equal protection (the constitutional guarantee of equal treatment).
