The IPF and all member federations as well as their individual members i.e. athletes and other persons abide by the WADA Code which is the universal document regarding anti-doping rules.
WADA CODE rule 2.10 explains that in sporting matters, we must not work or associate with individuals who are serving a period of ineligibility due to an anti-doping rule violation. Therefore, we remind athletes and officials of all our member nations that attending events or associating with a lifter serving a period of ineligibility is prohibited by WADA.
For further information please refer to the IPF Anti-Doping Rules article 2.10.
