Lia Thomas, the male swimmer who dominated at the 2022 NCAA women’s swim championships, has lost his lawsuit against World Aquatics.

In 2022, the international swimming federation updated its policies to better protect women’s sports, disallowing the participation of trans-identifying males who have advanced through puberty. Thomas sued to overturn the ban, arguing it was discriminatory. But this week, the Court of Arbitration for Sport (CAS) dismissed Thomas’s lawsuit on the basis that he did not have standing.

For now, female Olympic swimmers will be spared the farce of males competing in their category.
