VIO520. ABSOLUTE RESPONSIBILITY: AQHA rules pertaining to prohibition of drugs or surgical alteration provide for absolute responsibility for a horse's condition by an exhibitor, trainer, or Absolutely Responsible person or Responsible Party as affirmed by AQHA rules, whether or not he was actually instrumental in, or had actual knowledge of, the administration of such drug or surgery, thereby making such person eligible for possible disciplinary action upon proof of the presence of such drug by laboratory analysis or existence of surgical alteration. This rule of procedure for disciplinary action pertains to drug or surgical alteration cases in regard to notice, hearing and effect of suspensions or other sanctions, but burden of proof and presumptions as contained in said drug or surgical alteration rules specifically govern such cases.
