Gary Campion, aged 31, last of Pineview Gardens, Moyross, Limerick, had moved to appeal separate convictions for the murders in Limerick of bouncer Brian Fitzgerald outside his home and Frank Ryan, who was shot twice in the head by a passenger in his car.
Campion had denied being involved in the murder of Mr Fitzgerald, aged 34, at Brookhaven Walk, Corbally, on November 29, 2002, and had also denied murdering Frank Ryan, aged 21, in Moyross, on September 16, 2006.
He was found guilty in two separate trials. Campion had his appeal against conviction for the murder of Mr Fitzgerald dismissed in July and his second conviction was confirmed by the Court of Appeal yesterday.
Martin O’Rourke, defending, had submitted the trial judge wrongly admitted into evidence statements by Errol Ibrahim, who was at the scene of the shooting and spoke to gardaí after it.
Mr Ibrahim later resiled from what he had said but the prosecution successfully sought to admit his statements into the case.
The court heard Mr Ryan had been shot twice in the head while seated in his car. The car was between two street lamps and the evidence was the lamps were not working on the night.
Mr Ibrahim was a passenger in the car and the prosecution relied on him as a witness, Mr O’Rourke submitted.
Yesterday, Mr Justice George Birmingham said the court had considered all of the arguments advanced by Campion’s lawyers and “the court rejects all of them”.
