US Supreme Court Upholds State Bans on Transgender Athletes in Female School Sports
Landmark ruling allows states to restrict transgender girls from competing in girls’ and women’s school sports, marking another major legal victory for the Trump administration.
In a landmark decision with far-reaching implications for education, civil rights and transgender rights, the U.S. Supreme Court has upheld state laws banning transgender girls from participating in girls’ and women’s school sports. The ruling affirms that states may base athletic eligibility on biological sex, rejecting legal challenges brought against laws in Idaho and West Virginia.
The Court unanimously ruled that the state laws do not violate Title IX, the federal law prohibiting sex-based discrimination in education. By a separate 6-3 vote, the Court’s conservative majority also concluded that the bans do not violate the Equal Protection Clause of the U.S. Constitution’s 14th Amendment.
Writing for the majority, Justice Brett Kavanaugh said states have the constitutional authority to preserve girls’ and women’s sports for biological females. The Court held that legislatures may determine athletic eligibility based on biological sex in order to promote fairness and safety in competitive sports.
The ruling overturns earlier lower-court decisions that had allowed two transgender students—Lindsay Hecox in Idaho and Becky Pepper-Jackson in West Virginia—to compete on female sports teams while their legal challenges proceeded. The Supreme Court’s decision now reinstates the states’ restrictions in full.
The decision is expected to influence similar laws across the United States. More than 25 states have already enacted legislation limiting transgender participation in female school sports, and legal experts say the ruling provides a stronger constitutional foundation for those measures while encouraging additional states to adopt comparable policies.
President Donald Trump welcomed the judgment, describing it as a victory for women’s sports and a fulfillment of one of his administration’s major policy priorities. Since returning to office, Trump has pursued multiple executive and legal initiatives aimed at limiting transgender participation in sports, military service and other areas of public life.
Civil rights organizations, including the American Civil Liberties Union (ACLU), sharply criticized the ruling, arguing that it discriminates against transgender students and undermines equal educational opportunities. Advocacy groups warned that the judgment could have significant consequences beyond athletics by shaping future litigation involving transgender rights in schools and other public institutions.
Legal scholars say the Court distinguished competitive sports from other areas of anti-discrimination law, emphasizing that physiological differences may justify separate athletic categories. The majority stressed that its ruling is limited to organized school athletics and does not resolve every legal question involving transgender rights under federal law.
The decision marks one of the most consequential rulings of the Supreme Court’s 2025–26 term and adds to a series of judgments expanding states’ authority to regulate transgender-related issues. With the Court providing constitutional backing for state sports bans, the national debate over transgender rights is now expected to shift toward legislatures, federal agencies and future legal challenges involving education, healthcare and public accommodations.
