evidence: Transgender swimmer Lia Thomas has spoken out after losing a legal battle that will essentially see her barred from competing in next month's Olympics in Paris. [...] Thomas asked CAS to overturn the ruling last year, arguing that the guidelines were discriminatory and unlawful. The rules were put in place after former University of Pennsylvania student Thomas became the first transgender woman to secure a National Collegiate Athletics Association (NCAA) swimming championship victory in 2022. [...] Since tying with Thomas in the 2022 200-yard NCAA freestyle, Gaines has campaigned against trans inclusion in women's categories in sport, arguing those with biologically male bodies have an unfair advantage over biological women. Gaines has also filed a lawsuit against the NCAA for allowing Thomas to compete in the 2022 championships.
