The appellant, a horse trainer, appealed penalties imposed after two horses tested positive for aminorex, a Class I drug.
The panel heard expert testimony that the only known source of aminorex, other than direct administration, was through levamisole, which was not implicated here.
Given the absolute liability rule but the lack of a determined source for the drug, the panel adjourned the appeal for six months to allow for further investigation into other potential causal links and alternative measures for dealing with aminorex positives.
A conditional stay of the penalties was granted in the interim.
