Sun Yang v. WADA & FINA – A CAS letter on the admissibility of the appeal is not an appealable decision to the Swiss Federal Tribunal

Swimming – Doping – Appeal against a non-final arbitral award – alleged erroneous decision on jurisdiction (“ration termporis”)- decision on admissibility of the time limits to appeal is not a “decision” open to challenge before the Swiss Federal Tribunal – lack of legal interest worthy of protection in the annulment of a CAS decision
