Transgender swimmer Lia Thomas from the University of Pennsylvania has seen her legal case against World Aquatics dismissed by the Court of Arbitration for Sport, according to reports this week.
Her case was focused on trying to overturn a World Aquatics vote that took place in 2022, stopping transgender swimmers who "have gone through any stage of the process of male puberty" from competing in women's races.
Thomas was trying to argue that the rules were discriminatory. But the court found that Thomas is not allowed to race in competitions through World Aquatics or USA Swimming.
The sport's court said: “She is currently only entitled to compete in USA Swimming events that do not qualify as ‘Elite Events’."
World Aquatics said: “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 called the ruling "a major step" to "protect women's sports".
It added: “Our policies and practices are continuously evaluated to ensure they align with these core values, which led to the introduction of our open category."
“We remain committed to working collaboratively with all stakeholders to uphold the principles of inclusivity in aquatic sports and remain confident that our gender inclusion policy represents a fair approach.”
Outspoken biological female swimmer Riley Gaines, who has been fighting to keep biological men out of women's sports, commented on her X account: "Great news! Lia Thomas won't be able to compete in women's category at the Olympics or any other elite competition."
She wrote: "He has just lost his legal battle in Court of Arbitration for Sport ruling. This is a victory for women and girls everywhere."
