Caster Semenya, the Olympic 800 metres female champion can now participate in competitions following a Swiss court ruling on Monday.

According to her legal team, Semenya will not need to take testosterone-reducing medication before participating in competitions after the court temporarily suspended a new IAAF ruling.

Last  month, the 28-year-old Semenya lost her challenge at the Court of Arbitration for Sport (CAS) against the implementation of a restriction on testosterone levels in female runners.

The ruling would have affected women competing from 400 metres to the mile.

“I hope following my appeal I will once again be able to run free. I am thankful to the Swiss judges for this decision,” she said.

Following the decision by CAS, the South African took her appeal to the Federal Supreme Court of Switzerland, citing the need to defend ‘fundamental human rights’.

Her legal representative, Dr. Dorothee Schramm said: “The court has granted welcome temporary protection to Caster Semenya. This is an important case that will have fundamental implications for the human rights of female athletes.”

In its initial judgement, CAS found that the new rules proposed by the athletics’ world governing body, IAAF for athletes with differences of sexual development (DSD) were discriminatory but concluded that the discrimination was “necessary, reasonable and proportionate” to protect the integrity of female athletics.
