The Principle of Strict Liability

In anti-doping, the principle of Strict Liability applies in case there is a prohibited substance found in an athlete’s bodily sample – if it is in the athlete’s body, the athlete is responsible for it.

This means that every athlete is strictly liable for the substances found in their urine and/or blood sample collected during doping control, regardless of whether the athlete intentionally or unintentionally used a prohibited substance or method. Therefore, it is vital that athletes and Athlete Support Personnel know the rules and understand their responsibilities under the Code.

Athletes must also know and understand the Prohibited List and the risks associated with supplement use. More information on the Prohibited List, medications and supplements is available in the Prohibited List and Supplements and Medications sections.
