TIL Desk Sports/ While handing down a four-year ban on Narsingh Yadav, the Court of Arbitration for Sports has ruled that the wrestler failed to produce any “real evidence” regarding the sabotage theory he had advanced and the balance of probabilities” was that he orally took the banned substance intentionally in tablet form on more than one occasion.
In its full award, the ad hoc panel of the CAS relied on expert evidence that Narsingh’s dope offence was not due to one-time ingestion of the prohibited substance and its concentration in the first test result (of June 25) was so high that it had to come from an oral ingestion of one or two tablets of methandienone, rather than from a drink where the powder had been mixed with water.
The expert opinion was given by Professor Christiane Ayotte from Canada who was presented by the World Anti-Doping Agency. Professor Ayotte is a member of IAAF Doping Commission since 1995 and was elected representative of the Heads of IOC Accredited Laboratories in 1995-1996. She is currently the Director of the WADA-accredited laboratory in Montreal.
