Decision tomorrow on Semenya

The Court of Arbitration for Sport will reveal its decision in the landmark dispute over testosterone limits for female athletes at noon tomorrow, the Lausanne-based court has announced.

World athletics’ governing body the IAAF wants to setalimitonhowmuchtestosterone female athletes in specific track events can have in their bloodstream, forcing those with high amounts to reduce their levels closer to the normal female range.

The governing body believes female runners with high testosterone levels have an unfair advantage in events from 400 metres to the mile. It wants athletes to suppress their levels by surgery or medication to be eligible for toptier international races.

Double Olympic 800 metres champion Caster Semenya would be the most high-profile athlete affected by the rule and she and Athletics South Africa challenged it last November, postponing its introduction.

Their appeal was heard at CAS in February and it was initially hoped a decision, which could have major implications for women’s sport, would be made by the end of March, only for sport’s highest court to announce last month that it needed more time.

CAS said the verdict will be published on its website at 1200 Central European Time tomorrow.
