The IBU is a Signatory to the World Anti-Doping Code and cooperates with WADA to apply and implement the World Anti-Doping Code in the sport of Biathlon. These 2021 IBU Anti-Doping Rules have been adopted and will be implemented to comply with the IBU’s obligations as a Signatory to the World Anti- Doping Code, and to further the IBU’s continuing efforts to eradicate doping in the sport of Biathlon. They are intended to implement the requirements of the 2021 version of the World Anti-Doping Code in the sport of Biathlon, and will be interpreted and applied in a manner that is consistent with the World Anti- Doping Code and the International Standards. The World Anti-Doping Code and the International Standards (each as amended from time to time) are integral parts of these IBU Anti-Doping Rules and will prevail over these IBU Anti-Doping Rules in case of conflict. These IBU Anti-Doping Rules must be interpreted as an independent and autonomous text and not by reference to the existing law or statutes of any Signatory or government. The comments annotating various provisions of these IBU Anti-Doping Rules, the World Anti-Doping Code, and the International Standards will be used as an aid to interpretation of these IBU Anti-Doping Rules.
