Less than a week after South African Olympian Caster Semenya filed an appeal with Switzerland’s Supreme Court, the Swiss justices have temporary suspended the International Association for Athletic Federations regulations for female athletes with “differences of sex development” or DSD.

The swift decision means Semenya is immediately free to compete in races of all distances without medication to suppress her naturally elevated levels of testosterone.

Her South African attorney told The Independent that Semenya won her appeal against the controversial IAAF ruling, which mandated that in order to compete in track events from 400m to the mile, she had to take artificial hormones to lower her testosterone levels.

On May 29, Semenya filed her appeal of the 2-1 ruling by the Court of Arbitration for Sport, which upheld the IAAF’s rule change. But Monday’s decision by the Swiss Supreme Court suspends that ruling, and reports say it will remain in place until the 28-year-old’s appeal has been finalized.

This is a developing story and will be updated.
