On 26 August 2015, FINA tried to conduct an out-of-competition doping control test on the swimmer, William Brothers (CAN). The circumstances of this unsuccessful attempt constituted a potential violation of the FINA DC Rule 2.3 – evading, refusing or failing to submit to sample collection.

Following further investigation and a hearing in this matter, the FINA Doping Panel decided according to the FINA DC Rule 10.3.1 to impose on the athlete a sanction of four (4) years’ period of ineligibility commencing on 26 August 2015 and ending at the conclusion of 25 August 2019 for his first anti-doping rule violation.

The athlete appealed the FINA Doping Panel decision to the Court of Arbitration for Sport (CAS) in Lausanne. The CAS Pane partially upheld athlete’s appeal and declared him ineligible to compete for a period of two (2) years commencing as of 26 August 2015.
