Greyhound racing board chairman Paschal Taggart pledged at the weekend that details of all positive drug tests on greyhounds will be published in future.
Mr Taggart went ahead with a press conference in Shelbourne Park in Dublin at the weekend, against the wishes of Minister for Sport John O'Donoghue.
An estimated 200 people from the greyhound industry turned up to show their support for the Bord na gCon chairman.
Mr Taggart's position has been under pressure since it emerged that the board failed to publish details of a hearing at which two greyhound trainers, Paul Hennessy and John Kiely, were fined €1,000 and forced to forfeit prize-money because their dogs tested positive for a banned substance, erythopoietin (EPO), after two races in Dublin last year.
Questioned about the decision at the weekend, Mr Taggart said that if the issue arose again, he would publish details of such a hearing, and added that he would be recommending to Bord na gCon that it do so from now on.
"I am going to put it before the board that all positive tests are going to be published in the media," he said.
Bord na gCon is not obliged to publish details of positive tests, but does so as a matter of policy.
However, in the case of the hearing at which Mr Hennessy and Mr Kiely admitted that EPO had been administered to their dogs, the board decided not to publish on the grounds that it was not in the greyhound industry's interest.
News of its decision emerged last month after the sacking of the Bord na gCon chief executive, Aidan Tynan, who wrote to Mr O'Donoghue criticising the move and warning it could have implications for the sport's integrity.
Mr Taggart reiterated at the weekend that the two events were not connected. Mr Tynan was sacked after a series of disputes with the board over cash flow and costs, he said.
The two issues are the subject of an independent inquiry being carried out by a former Department of Justice secretary general, Tim Dalton.
The Minister's office did not comment yesterday on Mr Taggart's decision to go ahead with the press conference.
