Ronan McNally lost his appeal against a 12-year disqualification for violating the racing integrity laws.
The Irish Horseracing Regulatory Board (IHRB) released the decision of an appeals body panel led by Justice Peter Kelly on Wednesday night. The decision concerned the largest penalty the regulator had ever imposed.
Although any future violation of the rules by McNally will result in the activation of the full sentence, the panel did make one concession by suspending the final four years of the disqualification.
