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 claims 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.
