On February 14, the Ad Hoc Division of the Court of Arbitration of Sports (CAS) decided not to impose any provisional ban on Russian figure skater Kamila Valieva from participating in the ongoing Beijing Olympics. She was accused of being in violation of the World Anti-Doping Code (WADC) for taking the banned substance, trimetazidine.
The banned substance was found in the mandatory blood sample provided by her, which led to the Russian Anti-Doping Agency (RUSADA) endowing her a provisional suspension on Feb 8. The ban was overturned a day later. The overturning of the ban was challenged by the International Olympic Committee (IOC), the World Anti-Doping Agency (WADA) and the International Skating Union (ISU) at the CAS.
