The Swiss Federal Supreme Court on Monday ordered the International Association of Athletics federations to suspend action against South African athlete Caster Semenya until her appeal against testosterone rules has been finalized according to the athlete’s lawyer.
The Court of Arbitration for Sport last month approved IAAF’s rule which requires athletes with differences in sexual development to lower their testosterone levels to compete with women in the 400m range .
South Africa announced Friday that it had joined Caster Semenya’s appeal against the rule which the athlete says did not consider medical protocols and health consequences.
This means that for now, the Double olympic champion is free to run without taking medication.
The IAAF has until 25 June to respond to the application.
