Simpson failed a drug test at the National Championships last May, and is relying on mitigating circumstances in consuming the supplement Epiphany D1, that they argued contained the banned substance oxilofrine.
The hearing, which started on January 7, was scheduled to last two days, but the Jamaica Anti-Doping Disciplinary Panel could not conclude the case in time, as a key witness and a lab report were pending.
Simpson, 29, is represented by the law firm Samuda and Johnson, through attorneys Kwame Gordon and Danielle Chai, and will again appear before the three-member panel led by attorney Lennox Gayle, Dr Jephthah Ford and former FIFA referee Peter Prendergast.
The 2004 Athens Olympics 4X100m relay gold medallist had argued that the Epiphany D1 supplement was given to her by Canadian physical trainer Chris Xuereb.
The 2006 Commonwealth Games 200m champion insisted that she didn’t knowingly take the banned substance, as she researched the unknown supplement thoroughly.
However, Lackston Robinson, JADCO’s attorney, argued that she was “significantly negligent” and could not rely on mitigating circumstances in her defence.
