Transgender swimmer Lia Thomas loses CAS case to overturn World Aquatics ban

:Lia Thomas, the transgender swimmer who was barred from competing in women's events, has lost her case against World Aquatics at the Court of Arbitration for Sport (CAS), swimming's governing body said on Wednesday.

The decision prevents the American from having any chance of competing at the Paris Olympics which begin on July 26. The U.S. Swimming Olympic trials begin on Saturday.

Thomas became the first transgender NCAA champion in Division I history but soon after World Aquatics (then called FINA) voted to restrict the participation of transgender athletes in elite women's competitions.

Thomas, 25, had lodged a case with CAS in January in a bid to overturn the ban and compete in elite female races again, arguing that the provisions are not only "invalid and unlawful" but also discriminate against her.

However, a three-member panel in the sport's top court dismissed the case.

The panel concluded that since Thomas is not entitled to participate in USA Swimming's elite events, "she is simply not entitled to engage with eligibility to compete" in World Aquatics competitions.

"The panel concludes that since the athlete is not entitled to participate in 'Elite Events' within the meaning of USA Swimming Policy, let alone to compete in a WA competition... she is simply not entitled to engage with eligibility to compete in WA competitions," it said.

World Aquatics welcomed the decision made by CAS which they said is a "major step forward" in their efforts to protect women's sport.

"World Aquatics is dedicated to fostering an environment that promotes fairness, respect, and equal opportunities for athletes of all genders and we reaffirm this pledge," it said.

"Our policies and practices are continuously evaluated to ensure they align
