The Irish Turf Club are "watching with interest" as Pat Hughes was named as a second trainer facing court charges related to the possession of substances contrary to regulations.
Hughes appeared in Carlow District Court on February 13 on eight charges of possession of animal remedies following an inspection at the Irish Grand National-winning trainer's Fenniscourt yard in February 2012.
The case was adjourned until May 8.
When contacted, Hughes said: "I have no comment at all."
Fellow handler Philip Fenton is due to appear at Carrick-on-Suir District Court on Thursday charged with similar offences in a case brought by the Irish Department of Agriculture, Food and the Marine.
The department confirmed it is also responsible for the case against Hughes, who is accused of having eight different substances in his possession.
A statement read: "The Department of Agriculture, Food and the Marine confirms that a hearing is scheduled for May 8, 2014 .
"Charges are being brought under the Animal Remedies legislation alleging offences relating to possession of animal remedies.
"A person who commits one of the offences listed above is liable on summary conviction to a fine not exceeding €5,000 or to a term of imprisonment not exceeding six months or to both."
Denis Egan, chief executive of the Irish Turf Club, said the authority will carefully monitor proceedings before deciding on any action.
He said: "We are aware of the Pat Hughes case. We are watching with interest and if anything comes out of it, we will take the appropriate action."
