The CAS doesn't determine cheating. This accusation only comes from fans who know much less than the CAS.
It is more than just "symantics". Cheating suggests fraud and deception for the purpose of gaining an advantage. For those non-haters just sticking with the facts and evidence, none of these elements have been determined for Houlihan, primarily because none of them are required for determining a doping violation.
As the Houlihan case has demonstrated, reasonable persons are easily confused by statistics, and therefore unwittingly susceptible to fallacies.
"Reasonable alibi" is something rather subjective. This raises the question if it is reasonable for a distance athlete to intentionally take nandrolone orally.
Yet, notwithstanding the verdict, the CAS decision gave us several reasons to still think that the unproven/unprovable scenario of accidental and unknowing ingestion by pork burrito, as unlikely as that may seem, could still be a likely source of the nandrolone, if not the most likely as Houlihan argued. Another reasonable alibi is contamination in one of the supplements she couldn't test.
