LAUSANNE, Switzerland -- Caster Semenya has won another court decision in her battle to get track and field's testosterone regulations thrown out.
The Olympic 800-meter champion's lawyers say the IAAF, the governing body of athletics, has failed with an urgent request to Switzerland's supreme court to have the testosterone rules immediately re-imposed on Semenya.
The Swiss supreme court ruled earlier this month that the regulations should be temporarily suspended for Semenya, who has appealed against them.
That full appeal could take a year or more to be heard. Semenya has requested the rules be suspended throughout the appeal process, possibly allowing her to run at this year's world championships without taking testosterone-suppressing medication.
The IAAF has until June 25 to respond to Semenya's request for a long-term suspension of the rules.
Semenya also says she was denied entry to the 800-meter race at the Diamond League event in Rabat, Morocco, this weekend despite the court order allowing her to run in her favored race again.
