World Anti-Doping Agency v Sun Yang – A case of a Court of Arbitration for Sport award being successfully set aside

It was reported on 24 December 2020 that the 3-time Olympic champion Chinese swimmer, Sun Yang, had succeeded in overturning the decision of the Court of Arbitration for Sport (“CAS”), apparently on the ground of bias of one of the CAS arbitrators on the CAS appeal panel. In February 2020, following an appeal from the World Anti-Doping Agency (“WADA”), CAS baned the swimmer for 8 years from the date of the arbitral award for violating Article 2.5 of the Fédération Internationale de Natation Doping Control Rules (“FINA DC”), which is regarding tampering or attempted tampering with any part of doping control (4 years for violating Article 2.5 and the period of ineligibility being multiplied by 2 under Article 10.7.1(c) FINA DC for the violation being the second anti-doping violation).
