The US Supreme Court has ruled that states may lawfully bar transgender athletes from competing in girls' and women's sports. The 6-3 ruling, handed down on 30 June 2026, upholds laws in West Virginia and Idaho and is expected to validate similar bans already in place across 27 states.
Justice Brett Kavanaugh, writing for the majority, concluded the laws violate neither the Fourteenth Amendment nor Title IX. He declared that 'the Constitution and Title IX do not require an overhaul of women's and girls' sports throughout America.' The decision caps a year-long legal battle that began with two teenage and young adult athletes and ends with a ruling likely to reshape school sports nationwide.
