Relatives of those killed in the 1998 Omagh explosions have backed calls for a public inquiry into the Dublin and Monaghan car bombings 29 years ago.
Mr Justice Henry Barron this week accused the Fine Gael/Labour coalition government of 1974 of failing to show adequate concern and interest in the suffering caused by the loyalist attacks which killed 33 people and an unborn baby.
He accused the gardai of falling short in its investigation into the attacks and of failing to act on vital intelligence and leads.
The judge also suggested that some elements within the RUC and UDR were likely to have had a role in the bombings, either having knowledge of or participating in the planning of the attacks.
Omagh relatives' representative Michael Gallagher last night called on the Irish government to plough the same energy into establishing a public inquiry as it did into encouraging its British counterpart to set up the Saville Inquiry into the Bloody Sunday killings.
"People need the same kind of justice, the same kind of impartiality and transparency that the Irish government demanded of the British government in the Bloody Sunday inquiry," he said.
"The government should now do the decent thing and set up an inquiry that has teeth."
Mr Gallagher, whose son died in the Real IRA attack on Omagh, said that families in the Co Tyrone town had become increasingly disillusioned by the unwillingness of the government to publish the Nally Report.
The document contains the findings of an investigation into allegations that gardai failed to act on knowledge that dissident republicans were planning a bomb attack in Northern Ireland before the Omagh blast which killed 29 people and unborn twins.
He also accused Taoiseach Bertie Ahern of snubbing the families by ignoring their requests for a meeting for the past three years.
"We have had very similar experiences to the Dublin and Monaghan families," Mr Gallagher said.
"We have been totally let down by the Irish government".
Justice for the Forgotten chairwoman Bernadette McNally said the report had confirmed a lot of the relatives fear, concerning government inaction and suspected collusion.
Commenting on the revelation that entire files had gone missing from the Department of Justice, Ms McNally said: "That was more than we had expected but we weren't surprised."
"The report shows that we were abandoned by the government. That they tried to air-brush what happened out of history.
"All that must be thoroughlyinvestigated and we will continue digging until we get a satisfactory conclusion."
