The Court of Criminal Appeal will today hear an appeal by Dublin man Brian Rattigan against his conviction for murder.
The 30-year-old, with an address at Cooley Rd in Drimnagh, was found guilty by a jury of stabbing Declan Gavin outside Abrakebabra on August 25, 2001.
He was jailed for life in 2009 after a jury convicted him of the murder of 21-year-old Gavin eight years earlier.
There was evidence that a man in a balaclava got out of a Nissan Micra that pulled up outside Abrakebabra at the Crumlin shopping centre and made for his victim with a knife.
Rattigan's palm print was found at the scene.
Moments before the killing witnesses heard someone in the car shouting at Gavin, calling him a "rat".
Rattigan is now appealing against his murder conviction in a hearing scheduled to last two days.
