Caster Semenya has released a list of experts she will call in her appeal hearing at the Court of Arbitration for Sport (CAS) this week in her fight against regulations aimed at lowering the testosterone levels of hyperandrogenic athletes like her.
The South African 800-metres double Olympic champion has expressed her disappointment after the International Association of Athletics Federations (IAAF) revealed the names of their five witnesses for the proceedings in Lausserne.
She called it a breach of confidentiality rules ahead of a five-day appeal that could have far reaching consequences for sport. The IAAF deny any wrong-doing.
She will call on a range of experts from various fields, and used the announcement of their names, through her lawyers, to reiterate her stance on the IAAF's proposed regulations.
"The IAAF regulations do not empower anyone," the statement said. "Rather, they represent yet another flawed and hurtful attempt to police the sex of female athletes.
"Ms Semenya's courage and perseverance in her fight to run free is an inspiration to young athletes in her home country of South Africa and around the globe."
The IAAF regulations stipulate that women with elevated testosterone take medication to reduce their level before being allowed to compete, but only in the middle-distance events of between 400- and 1500-metres where it is claimed the advantage is most felt.
IAAF President Sebastian Coe told reporters on Monday that the regulations are aimed at leveling the field between hyperandrogenic athletes and those with normal levels of testosterone.
The IAAF's previous attempts to regulate testosterone in female athletes fell foul of a CAS ruling in 2015 following an appeal on behalf of Indian Dutee Chand, who had been banned from competing because of her high levels.
CAS claimed in their judgment that the IAAF had not provided sufficient evidence that hyperandrogenic athletes gained a significant advantage due to their testosterone count.
A verdict could take up to a month, according to CAS.
The experts who will testify in support of Semenya are listed as:
Professor Veronica Gomez-Lobo, Dr Alun Williams, Professor Eric Vilain, Professor Roger Pielke, Professor Dankmar Bohning, Professor Richard Holt, Professor Anthony C Hackney, Dr Lih-Mei Liao, Dr Payoshni Mitra and Ashley LaBrie.
