1. Rule 30 of the Olympic Charter assigns the international federations the responsibility to “establish and enforce, in accordance with the Olympic spirit, the rules concerning the practice of their respective sports and to ensure their application”. The mission of the NOC's, on the other hand, is to “fight against the use of substances and procedures prohibited by the IOC or the IFs”. This mission is focused upon political actions vis-à-vis the competent authorities of their respective countries.
