CAS suspends IAAF's post-Semenya rules on women athletes with high male hormones

LAUSANNE, Switzerland — The Court of Arbitration for Sport has suspended IAAF rules governing female athletes who have high level of male hormones.

The rules were introduced in 2011, after South African 800-meter runner Caster Semenya was sidelined for almost a year after winning the 2009 world title when she was 18.

The court says its interim ruling clears Indian sprinter Dutee Chand to compete and gives the governing body until July 24, 2017, to present new scientific evidence.

The IAAF's rules on hyperandrogenism— or the presence of high levels of testosterone — will be declared void if no evidence is presented by the deadline.

Chand appealed to CAS after India's athletics body barred her from competition.

CAS previously let the 19-year-old sprinter run in international events pending a verdict.
