Gerry "The Monk" Hutch and ex-Sinn Fein councillor Jonathan Dowdall have lost their High Court actions aimed at preventing them from being tried before the non-jury Special Criminal Court on charges of murder arising out of the Regency Hotel attack in 2016.
In his judgement on Friday, Mr Justice Anthony Barr said he was satisfied to dismiss the men's actions.
The judge said that having considered all the various arguments raised by the parties he had reached the conclusion that all of the reliefs sought by the two accused "must be refused."
