LAUSANNE, Switzerland — Transgender swimmer Lia Thomas has asked a Swiss sports court to overturn rules imposed by World Aquatics that stop her from competing in elite women's races that she says are discriminatory.
The Court of Arbitration for Sport said Friday it had registered Thomas' request, but no date for a hearing was decided. Confidentiality around a case that began in September was lifted after it was reported in British media. «Ms Thomas seeks an order from the CAS declaring that the [World Aquatics rules] are unlawful, invalid, and of no force and effect,» said the court based in the Olympic home city of Lausanne, Switzerland.
World Aquatics agreed on rules in June 2022 that banned transgender women who have been through male puberty from competing in women's races.
It also created an «open» category for which transgender athletes would be eligible. Other Olympic sports bodies, including track and field and cycling, have since adopted similar rules, which supporters say acknowledge physical advantages from male puberty that athletes retain long term after transitioning.
