Australian swimmer Shayna Jack has always denied consuming ligandrol, a banned performance enhancing drug. But, when Jack was subject to an out-of-competition anti-doping test at Tobruk Pool in Cairns in 2019, she returned an adverse analytical finding. As is protocol, Jack was issued a provisional suspension, the suspension was made public and the swimmer was ultimately handed a four-year ban from the sport.
On appeal, Jack insisted that she had not knowingly taken ligandrol. She speculated that legal supplements she was taking might have been contaminated, or that she could have come into contact with the substance while using public pool facilities. But because the global anti-doping regime operates on a strict liability basis, a lack of evidence that Jack did not knowingly ingest ligandrol was insufficient.
