The Switzerland-based Court of Arbitration for Sport (CAS) has decided to delay to April 2019 its ruling on a challenge by South African Olympic Champion Caster Semenya.
Semenya filed against the IAAF’s new regulation to stop her from running races against fellow women due to her high levels of testosterone.
A decision in the controversial case had been due next week but the world’s top sport court said it would not issue a verdict “until the end of April” because both sides had filed additional material since the hearing ended in February.
Semenya has challenged the International Association of Athletics Federations’ proposals aim at restricting her and other African female athletes with high testosterone levels from world athletics races, suggesting they should instead race against male athletes.
According to the IAAF on Thursday, 21 March 2019, it is seeking to force “hyper androgenic” athletes or those with “differences of sexual development” to seek treatment to lower their testosterone levels below a prescribed amount if they wish to continue competing as women.
The athletics governing body argued the moves were necessary to create a “level playing field” for other female athletes.
A wide coalition has rallied behind Semenya’s cause, including the South African government and rights activists worldwide.
Some scientific experts have argued that barring Semenya from competition due to naturally high testosterone levels would be like excluding basketball players because they are too tall.
In addition, the IAAF’s move has been described as being racist because all the athletes the world athletics body has targeted are women athletes from South Africa, Burundi, Uganda and Kenya.
