In April 2020 the Canadian Centre for Ethics in Sport (CCES) has reported an anti-doping rule violation against the snowboard athlete Matt Hamilton after his sample tested positive for the prohibited substance GW501516.
After notification a provisional suspension was ordered and the Athlete requested an extention of the stipulated deadlines. However he failed hereafter to respond to the asserted violation and he ceased his engagement in the results management process.
Because the Athlete failed to dispute the asserted violation within the deadline under the Rules follows that the Athlete is deemed to have admitted the violation, to have waived his right for a hearing and to have accepted the proposed consequences.
Therefore the CCES decides on 28 May 2020 to impose a 4 year period of ineligibility on the Athlete starting on the date of the provisional suspension, i.e. on 8 April 2020.
