Athletics SA (ASA) has threatened to take the IAAF to the Court of Arbitration for Sport (CAS) if it does not withdraw its amended hyperandrogenism regulations.
The new rule will require women who produced natural testosterone levels of more than five nanomoles to either take medication to reduce it, compete in a different event or quit the sport.
ASA said it had decided to challenge the sport’s governing body on the new rules after consultation with Sports Minister Tokozile Xaba and the SA Sports Confederation and Olympic Committee.
“Based on this consultation, we have now taken a decision that we will challenge the IAAF on these new regulations as we have found them to be skewed,” ASA said in a statement on Thursday.
“As a member federation, we will engage the IAAF as our mother body and if they do not change their minds on this new rule after this engagement, we will proceed to CAS for further assistance on the matter.”
The new regulations are limited to female athletes that participate from the 400m to the 1500m which are the events South Africa’s middle-distance phenom Caster Semenya participates in.
