Semenya accuses IAAF of breach of regulations at CAS hearing

Caster Semenya has said the International Association of Athletics Federations (IAAF) breached confidentiality regulations ahead of her appeal hearing on Monday where she is fighting for her athletics future.

The South African 800-metres double Olympic champion is seeking to overturn a new set of IAAF regulations that are aimed at lowering the testosterone levels of hyperandrogenic athletes.

The appeal, being heard at the Court of Arbitration for Sport (CAS) in Switzerland, could be a landmark case for the sport with wide-reaching consequences.

Semenya believes the IAAF breached confidentiality rules of the hearing after they released the names of five expert witnesses they will bring to the CAS to testify on their behalf.

"The arbitration proceedings are subject to strict confidentiality provisions and this information should not have been released?" Semenya's lawyers said in a statement on Monday.

"Ms Semenya believes the IAAF press release is a clear breach of the confidentiality provisions that was orchestrated in an effort to influence public opinion in circumstances where the IAAF knew that Ms Semenya would not be prepared to respond because she was complying with her confidentiality obligations.

"As a matter of fairness Ms Semenya raised this issue with the CAS and has been granted permission to publicly release information responding to the IAAF press release? including disclosing the experts who are testifying in support of Ms Semenya's case. This information will be released tomorrow."

An IAAF spokesperson told Reuters they believe they were within their rights to make their witness list public.

"The IAAF does not believe the list of witnesses it will be calling is confidential, just their evidence at CAS," the spokesperson said.
