In a landmark legal challenge, three former swimmers from the University of Pennsylvania (Penn) have filed a lawsuit against the university, Harvard University, the Ivy League, and the NCAA, accusing them of violating Title IX by allowing Lia Thomas, a transgender woman, to compete in the 2022 Ivy League Women’s Swimming and Diving Championships. The lawsuit, filed in federal court on February 4, argues that Thomas’ participation in the women’s competition as a “trans-identifying male swimmer” deprived female athletes of equal opportunities under Title IX, a federal law that prohibits sex-based discrimination in educational programs, including athletics.

The plaintiffs—Grace Estabrook, a 2022 Penn graduate, and Margot Kaczorowski and Ellen Holmquist, both current students—claim damages for pain and suffering, mental distress, anxiety, and other related harms caused by their experiences as a result of Thomas’ inclusion in the competition. The lawsuit does not name Thomas as a defendant but targets the four institutions involved in her participation.
This case represents a significant development in the ongoing debate surrounding the inclusion of transgender athletes in women’s sports. The lawsuit’s plaintiffs argue that by allowing Thomas to compete in the women’s category, these organizations violated their rights as female athletes, including their right to compete in an environment that respects their privacy and equal opportunity to succeed.
The Claims: Title IX and Equal Opportunities
The plaintiffs allege that their rights under Title IX were violated by the decisions made by Penn, Harvard, the Ivy League, and the NCAA. They argue that allowing a transgender woman to compete in the women’s category prevented them from fairly competing for spots on the team and achieving personal success. Specifically, Holmquist claims that she was excluded from the 2022 Ivy League Championship roster because of Thomas’ participation, while Estabrook and Kaczorowski contend that they finished lower in the standings than they would have if Thomas had not been in the competition.
The lawsuit also includes Harvard University as a defendant due to its role as the host school for the 2022 Ivy League Championships. The plaintiffs allege that Harvard failed to provide accommodations for female athletes who did not want to share a locker room with Thomas, such as a unisex restroom or a separate facility for women who objected to the arrangement.
Allegations of Psychological Harm and Administrative Pressure
The plaintiffs further claim that their university administrators imposed pro-transgender ideology upon them and dismissed their concerns about sharing a team and locker room with Thomas. According to the lawsuit, Penn’s administrators suggested that any discomfort with Thomas’ presence on the team was a psychological issue, and they encouraged the athletes to seek counseling from the university’s LGBTQ+ center. The plaintiffs also allege that they were warned against speaking out publicly about their concerns, with administrators suggesting that doing so could damage their reputations and future job prospects.
The lawsuit highlights what the plaintiffs view as coercive tactics used by Penn’s administration to enforce compliance with the university’s policies regarding transgender athletes. The suit claims that Penn’s coach, Mike Schnur, informed swimmers that Thomas would not be using the women’s locker room, but that situation changed once the team returned to campus in the fall of 2021. The plaintiffs allege that they were shocked to discover that Thomas had been permitted to use the women’s locker room, and some of them confronted the coach in distress. According to the lawsuit, Schnur reportedly said he had no choice, as his job would be at risk if he didn’t allow Thomas to compete and use the women’s facilities.
Impact on the Ivy League and the NCAA
The lawsuit also raises concerns about the policies of the Ivy League and the NCAA, which the plaintiffs argue contributed to the situation. The athletes claim that the Ivy League Executive Director, Robin Harris, and other members of the League’s Council of Presidents used Thomas’ participation as a way to promote a public stance of support for “radical gender ideology.” The plaintiffs seek to hold these organizations accountable for their role in what they describe as a systemic attempt to force transgender ideology onto female athletes and sports teams.
The lawsuit is being supported by the Independent Council on Women’s Sports (ICONS), an organization that advocates for policies that protect women’s sports. ICONS has also backed other legal challenges related to transgender athletes, including a case filed by former swimmer Riley Gaines, who competed against Thomas at the 2022 NCAA Championships.
Broader Context and Legal Implications
The case is part of a broader national conversation about the inclusion of transgender athletes in women’s sports. This issue has gained significant political and legal attention, with some states passing laws restricting transgender participation in women’s sports and others pushing back against such measures. In response to the growing controversy, former President Donald Trump signed an executive order on February 5 banning transgender athletes from competing in women’s sports, and the U.S. House of Representatives passed the “Protection of Women and Girls in Sports Act” in January, which would withhold federal funding from schools that allow transgender women to compete in female sports.
At the NCAA level, President Charlie Baker has defended the organization’s policies, stating that transgender athletes should have access to alternative facilities if they are uncomfortable sharing spaces with transgender athletes. However, the legal landscape surrounding this issue remains fluid, and the outcome of the current lawsuit could play a significant role in shaping future policy.

As the case continues to develop, it will likely further fuel the ongoing debate over how to balance fairness and inclusion in college athletics. The outcome of this lawsuit may set a precedent for how universities and sports organizations handle the participation of transgender athletes in women’s competitions, and whether Title IX protections are being adequately enforced to ensure equal opportunities for all female athletes.
