An IRA killer has launched a High Court challenge to having his early release licence revoked for trying to murder again.
Robert Duffy, from north Belfast, faces being extradited back to Northern Ireland after he serves a new sentence for shooting a man in the Republic.
He is seeking to quash decisions by the Sentence Review Commissioners, claiming he does not pose a danger to the public in Northern Ireland.
Duffy (39) was originally jailed for life for the murder of John Gibson, a construction worker hired by the RUC, in Newtownabbey in October 1993.
He was freed in 2000 under the early release terms of the Good Friday Agreement, just four years into his sentence.
After his release he moved across the border to Dundalk.
In 2008 he was jailed for a gun attack on Colin O'Neill during a row at a bar in the Co Louth town.
Following the new conviction, his early release licence in Northern Ireland was suspended.
