CASTER SEMENYA will be able to race without taking medication to reduce her testosterone levels, a Swiss court has ruled.

Semenya had faced the options of medicating to lower the amount of the hormone in her system or switching events after a new IAAF ruling was introduced.

The 28-year-old had challenged the new regulations on testosterone limits in female athletes at the Court of Arbitration for Sport (Cas) but she lost after the panel ruled such discrimination was “necessary”.

Determined to fight the Cas decision, Semenya took her appeal to the Federal Supreme Court of Switzerland, which has granted her the right to race by temporarily suspending the new IAAF ruling.

“I hope following my appeal I will once again be able to run free,” the BBC reported Semenya said following the most recent ruling which means she can compete again.

“I am thankful to the Swiss judges for this decision,” she added.

The Federal Supreme Court of Switzerland told the BBC in a statement that it had “super-provisionally instructed the IAAF to suspend the application of the ‘Eligibility Regulations for the Female Classification for athletes with differences of sex development’ with respect to the claimant, until the decision on the request for issuance of provisional measures”.

In a statement delivered following the Cas ruling in May, CAS secretary general Matthieu Reeb, said: “The panel found that the DSD regulations are discriminatory but the majority of the panel found that on the basis of the evidence submitted by the parties in the procedure such discrimination is a necessary, reasonable and proportionate means of achieving the IAAF’s objective of preserving the integriuty of female athletics in some track events on international competitions that is from 400m to 1 mile.”
