Under the Hyperandrogenism policy of the International Association of Athletics Federations, female athletes with high levels of naturally producing testosterone are not allowed to compete on the ground that they have an unfair advantage over their peers.
Dutee was banned by the Athletics Federation of India in 2014 under this policy but she challenged this at the Court of Arbitration for Sports in Lausanne, Switzerland.
Dutee was allowed to compete both at the national and international events during those two years. But her future again came under a cloud after the IAAF decided last month to submit fresh evidence at the CAS in support of its policy of barring female athletes who produced natural testosterone (male hormones) above permissible range from taking part in competitions.
