In a recent ruling by the Court of Arbitration for Sport, transgender swimmer Lia Thomas was unsuccessful in her challenge against rules that prevent her from competing in elite women's races. The panel of three judges dismissed Thomas' request for arbitration with the World Aquatics governing body, citing that she did not have standing to bring the case.
World Aquatics had implemented a ban on transgender women who have undergone male puberty from participating in women's races, while also establishing an 'open' category for transgender athletes to compete in. Thomas sought to overturn these rules, claiming they were invalid, unlawful, and discriminatory.
