Liao Hui is a Chinese weighlifter. In September 2010 he tested positive to Boldenone (a steroid). Liao was suspended for 4 years, (rather than 2 years). Liao appealed to CAS, in relation to to testing procedure defects (this was unsuccessful, and against the increase of sanction from 2 years to 4 years. The CAS panel upheld this part of the appeal, and reduced the sanction to 2 years. The panel said:

In the present case the Panel is not persuaded to the degree of comfortable satisfaction that such aggravated circumstances exist. In the case at hand there is no indication that the Appellant committed the anti-doping rule violation “as part of a doping plan or scheme, either individually or involving a conspiracy”. Nor is there an indication that the Appellant used the prohibited substance on multiple occasions. In the case at hand the Appellant was submitted to two doping controls on the same day. The first doping control resulted – unlike the second one – in a negative finding. This is all the more surprising since the second test conducted by IWF was an“announced test”, i.e. that the Appellant knew at the time when he submitted to the first doping  control that a second one would follow shortly. In addition, the Appellant has submitted to other doping tests on 24 August 2010 and 30 August 2010  all of  which were reported negative. It follows from this that there is no evidence on file that Appellant has made “repetitive use of a prohibited substance” or that he was undertaking any steps beyond simply having the prohibited substance or its metabolites in his specimen. Furthermore, no evidence has been adduced that the Appellant would  “likely enjoy the performance enhancing effects of the anti-doping rule violation beyond the  otherwise applicable period of ineligibility” (i.e. the two-years-sanction). Finally, the Panel notes that there is no evidence on file that the Appellant “engaged in deceptive or obstructing conduct to avoid the detection or adjudication of an anti-doping rule violation”.
