Transgender swimmer Lia Thomas out of Olympics after losing

Athlete said rules were ‘invalid and unlawful’World Aquatics: ‘Major step to protect women’s sport’

The US swimmer Lia Thomas, who rose to global prominence after becoming the first transgender athlete to win a NCAA college title in March 2022, has lost a legal case against World Aquatics at the court of arbitration for sport – and with it any hopes of making next month’s Paris Olympics.

The 25-year-old also remains barred from swimming in the female category after failing to overturn rules introduced by swimming’s governing body in the summer of 2022, which prohibit anyone who has undergone “any part of male puberty” from the female category.
