Trainer Peter Moody will find out next week if he has been found guilty of cobalt charges.
Moody's defence has blamed Lidari's elevated cobalt level after his second in the 2014 Turnbull Stakes on a stablehand mistakenly giving the horse large doses of oral hoof treatment Availa for months.
Racing Victoria stewards' legal counsel Jeff Gleeson QC last month said it was a lie and a failed attempt to concoct an innocent explanation for Lidari's cobalt reading, which was double the allowed threshold.
Victoria's Racing Appeals and Disciplinary Board will announce its finding at 10am (AEDT) on Wednesday.
Moody faces a minimum three-year ban if found guilty of administering a prohibited substance.
