1. The presence of two witnesses (instead of one) cannot be invoked as a circumstance invalidating the entire doping sample collection procedure. According to the Rules in force, the sample collection cannot take place without the testimony of at least a witness, but the presence of two witnesses is not prohibited and is not a reason for the invalidity of the procedure. In the same way, no rule provides for the presence of a representative of the athlete at the moment the athlete passes the sample. As a result, the fact that no representative assisted the Athlete while passing the urine cannot be invoked as an irregularity affecting the validity of the sample collection procedure.
