Australian Swimmer Shayna Jack Suspended for Two Years

The Court of Arbitration for Sport (CAS) in Australia has issued its decision in the arbitration procedure involving Australian swimmer Shayna Jack.


Shayna Jack has been found to have committed a violation of Article 2.1 of the Swimming Australia Ltd Anti-Doping Policy 2015 and has been suspended for a period of two years, starting from the date of her provisional suspension on July 12, 2019.

The doping control test conducted on June 26, 2019, revealed a positive result for "ligandrol," an anabolic agent prohibited at all times according to the World Anti-Doping Agency (WADA) Prohibited List. Consequently, Swimming Australia imposed a provisional suspension on Jack on July 12, 2019. After an investigation, on December 19, 2019, Australian Sports Anti-Doping Authority (ASADA; now "Sport Integrity Australia"), on behalf of Swimming Australia, issued an Infraction Notice to the athlete, indicating that a four-year period of ineligibility would be imposed, commencing from July 12, 2019, as a result of the anti-doping rule violation.

Jack appealed to CAS

On January 2, 2020, Shayna Jack filed a request for arbitration with the CAS Oceania Registry (CAS first instance). A hearing took place on September 25 and 28, 2020, with participants attending either in-person or via videoconference due to the prevailing sanitary restrictions.

The Sole Arbitrator responsible for the case determined, based on the balance of probabilities, that Shayna Jack did not intentionally ingest ligandrol and concluded that she had fulfilled her burden of proving that the anti-doping rule violation was not intentional. Consequently, the Sole Arbitrator imposed a reduced period of ineligibility of two years, starting from the date of her provisional suspension.
