World Anti-Doping Agency may take Sun Yang case to Court of Arbitration for Sport
Governing body to review Chinese claims amid suspicions of a cover-up

The World Anti-Doping Agency may appeal to the Court of Arbitration for Sport after Chinese swimming star Sun Yang served a three-month doping ban in secret.
A spokesman said Wada had not received full details of the case, while the World Anti-Doping Code says drugs violations must be made public within 20 days.
Chinese officials have denied covering up the suspension of the double Olympic champion, which took place between May and August but was only announced on Monday.
“Wada has not yet received the full decision regarding this case,” the spokesman said via email.
Wada will review the reasons ... and decide whether or not to appeal
“Once it is received, Wada will review the reasons for the decision and will subsequently decide whether or not to use its independent right of appeal to the Court of Arbitration for Sport.”
Section 14.2.2 of the World Anti-Doping Code says violations must be publicly reported within 20 days and that decisions have to be sent to Wada in the same time-period.
