US Supreme Court upholds bans on transgender athletesupholds bans on transgender athletes in women's sports
The US Supreme Court upheld state laws banning transgender athletes from women's sports teams on Tuesday, June 30, 2026, clearing the way for restrictions in states like Idaho and West Virginia.
Justice Brett Kavanaugh led the majority opinion determining that biological sex at birth is the lawful standard for sports eligibility under Title IX.
This ruling resolves a major legal conflict over gender identity in athletics and sets a national precedent for future state legislation.
US Supreme Court Majority
The Supreme Court majority interpreted Title IX and the Equal Protection Clause to mean that schools can base eligibility for women's sports solely on biological sex at birth, prioritizing traditional definitions of gender in athletics.
Student Challengers
Student challengers argued that banning transgender athletes discriminates based on sex and transgender status, violating the Constitution's 14th Amendment guarantee of equal protection and the federal civil rights mandate of Title IX.
- The 2020 Supreme Court ruling that sex discrimination includes transgender status in the workplace did not address sports eligibility under Title IX.
- Over 20 US states have proposed or passed similar transgender sports bans since Idaho's 2020 law was enacted.
- The West Virginia law defines female strictly by reproductive biology, a definition that contrasts with the American Psychological Association's gender identity guidelines.
