A U.S. Supreme Court decision clarifying that the term "sex" in Title IX refers to biological sex is impacting California's approach to transgender athletes in sports. The ruling, which came in the West Virginia v. B.P.J. case, has led federal authorities to scrutinize and take action against educational institutions within the state that permit biological males to compete on women's teams.

Federal agencies, including the U.S. Department of Education's Office of Civil Rights and the U.S. Department of Justice, have initiated Title IX investigations into several California colleges and school districts. These investigations stem from complaints alleging violations of Title IX's prohibition on sex discrimination.

One such investigation targets San Jose State (SJSU) and the broader California State University (CSU) system. The Department of Education's Office of Civil Rights previously concluded an investigation into SJSU, finding the university in violation of Title IX for allowing a biological male to play on its women's volleyball team. In response, SJSU and the CSU system filed a lawsuit against the Department of Education in an attempt to prevent enforcement of these findings.

The Supreme Court's affirmation that "sex" in Title IX cannot plausibly be interpreted to mean anything other than biological sex strengthens the federal government's position. This means that institutions allowing biological males to compete on female sports teams, even in states without explicit bans, could face threats to their federal funding.

Further investigations are underway concerning multiple California colleges and local school districts. One case involves three women's volleyball players at Santa Rosa Junior College who filed a Title IX complaint after losing roster spots. They protested the participation of a biological male on their team. A Title IX complaint was also filed against the California Community College Athletic Association (3C2A), the governing body for the state's community colleges, putting all 113 member institutions at risk of losing federal funding.

Additionally, the Jurupa Valley Unified School District is under investigation for permitting a biological male student to compete on girls' volleyball and track teams. The recent Supreme Court ruling may also impact policies like the one implemented by the California Interscholastic Federation (CIF), which has mandated shared podiums for female and biological male athletes.

While the implications of the ruling are still unfolding, potential avenues for compliance are being explored. Justice Brett Kavanaugh, in his majority opinion, suggested the creation of coed teams as a possible compromise, allowing all students an opportunity to compete. Such a model could potentially offer a solution to balance inclusivity with the court's interpretation of Title IX.
