In Oliviera v USADA, the Court of Arbitration for Sport considered the cases surrounding reduction of the 2 year penalty where a cyclist was the subject of a positive test, due to a contaminated supplement. In the circumstances of the efforts taken by the cyclist to determine that the supplement contained no prohibited substances, and her elite but reasonably inexperienced status as a cyclist, with little formal training in relation to prohibited substances, and her early acceptance of a provisional suspension, the panel concluded that her suspension should be reduced from 2 years to 18 months, and the start date for the suspension should be the last date on which she had competed.
