Interestingly, an Indian, star sprinter Dutee Chand, is behind the promulgation of new rule, though completely inadvertently. In 2014, the IAAF barred Dutee for hyperandrogenism—a condition in which a woman produces excess male sex hormones like testosterone—and the Athletics Federation of India (AFI) promptly dropped her just before the 2014 Commonwealth Games. Frustrated, Dutee moved the Court of Arbitration for Sport (CAS), the highest judicial forum in sports. In April 2015, the CAS ruled in favour of the pint-sized Orrisa athlete, suspending the IAAF’s regulations. The CAS also told the IAAF to do more research on hyperandrogenism and gave it two years to complete it. Now, IAAF has come up with the findings of a research and tweaked its rules for athletes with a Difference of Sexual Development (DSD), as it chose to define them. Significantly, IAAF has kept sprinters out of the regulations, thus making Dutee free to run in 100m and 200m, her pet events.
