The World Anti-Doping Agency (WADA) confirms that on Thursday 26 September, it lodged an appeal to the Court of Arbitration for Sport (CAS) in the case of Italian tennis player, Jannik Sinner, who was found by an independent tribunal of the International Tennis Integrity Agency (ITIA) to bear no fault or negligence having twice tested positive for clostebol, a prohibited substance, in March 2024. 

It is WADA’s view that the finding of “no fault or negligence” was not correct under the applicable rules. WADA is seeking a period of ineligibility of between one and two years. WADA is not seeking a disqualification of any results, save that which has already been imposed by the tribunal of first instance. 

As this matter is now pending before CAS, WADA will make no further comment at this time.
