Supreme Court Upholds State Bans on Transgender Girls' Participation in Sports
The high court ruled that states may define sports eligibility based on biological sex, upholding Idaho and West Virginia laws and prompting reactions from politicians and advocacy groups.
The U.S. Supreme Court issued a split decision that allows states to bar transgender athletes from girls' and women’s sports teams when eligibility is defined by biological sex. The ruling upheld Idaho and West Virginia statutes and left the interpretation of Title IX to individual states.
Justice Brett Kavanaugh, writing for the conservative majority, said the word “sex” in Title IX “cannot plausibly be interpreted to refer to anything other than biological sex.” He added that the desire of transgender athletes to compete “warrants respect,” and that no student should be “ostracized or vilified.”
The Court’s three liberal justices dissented, arguing that the case should have been allowed to proceed in lower courts to assess whether the laws violate equal-protection guarantees. Justice Sonia Sotomayor warned that denying transgender athletes participation “simply because it thinks they have an inherent athletic advantage” disregards the benefits of school sports.
The decision follows a wave of state legislation—27 states have enacted bans—largely backed by Republican-led legislatures. Advocates for transgender rights said the ruling underscores the need for inclusive policies in Democratic-led states, while the Human Rights Campaign emphasized that the decision does not create a nationwide ban.
President Donald Trump praised the outcome as a “big win,” and West Virginia Governor Patrick Morrisey said it provides “certainty, fairness and opportunity” for female athletes. Supporters of the bans, including Alliance Defending Freedom president Kristen Waggoner, warned that other states could face similar legislation.
Legal challenges to the bans continue. In West Virginia, high-school student Becky Pepper-Jackson and in Idaho, college student Lindsay Hecox had argued that the laws violated the Constitution and Title IX. Lower courts had previously blocked enforcement, allowing the athletes to compete while litigation was pending.
The ruling arrives as the Supreme Court’s recent term has seen several decisions that limit transgender rights, including upholding a Tennessee ban on gender-transition medication for minors and rejecting a Colorado law protecting LGBTQ youth from conversion-therapy.
The case highlights ongoing debates over fairness, scientific uncertainty, and discrimination in school sports, with both political and advocacy groups preparing for further legal and legislative battles.
