The verdict in a multimillion-pound legal action by relatives of some of the 29 people killed in the Omagh bomb is due to be delivered next month.
Court officials in Belfast confirmed today that Mr Justice Morgan will deliver his judgment on June 8th.
The families took the High Court civil action against five men whom they claim were responsible for the Real IRA bombing in August 1998. Nobody has ever been convicted of the murders.
It is believed to be the first time anywhere in the world that alleged members of a terrorist organisation have been sued. Michael McKevitt, an alleged founding member of the dissident republican group, is among the five facing the claim for damages estimated at up to £14 million.
All the men deny any involvement.
The High Court action began in Belfast more than a year ago at a cost to the families of £2m and followed a major funding raising campaign which was supported by the former US president Bill Clinton and ex-Northern Ireland Secretaries of State Peter Mandelson and Sir Patrick Mayhew as well as celebrities Bob Geldof and former boxing champion Barry McGuigan.
At one stage the hearing moved to Dublin where Mr Justice Morgan heard evidence from Garda officers who were involved in the cross-border police investigation.
In December 2007, Sean Hoey, 38 from Jonesborough, South Armagh was cleared at Belfast Crown Court of murdering the 29 people. He was acquitted of a total of 58 charges, including some not directly linked to the bombing.
Michael Gallagher, whose son Aiden (21) was among the dead said today: "This is another landmark for the families and we are grateful that at long last we are coming to the end of a very lengthy legal process."
