Two men held liable for the Omagh bombing have been denied authorisation to appeal to the Supreme Court in London.
Senior judges in Belfast refused to grant leave for jailed Real IRA leader Michael McKevitt and fellow dissident republican Liam Campbell.
They also rejected applications by another man now facing a civil retrial over the atrocity, Seamus Daly, and by the victims' relatives who brought the landmark action. But lawyers for the defendants and plaintiffs are all now set to petition the Supreme Court directly. No-one has been convicted of the Real IRA bomb attack which devastated the Co Tyrone market town in August 1998.
McKevitt, a convicted Real IRA leader serving a 20-year jail sentence; Campbell, a farmer from Co Louth currently fighting extradition to Lithuania over an alleged arms smuggling plot; Colm Murphy, a Dundalk-based builder and publican, and Daly, from Culoville, Co Monaghan, were all held liable for the bombing in a civil ruling delivered in June 2009.
In July this year appeals by Murphy and Daly against the verdict were upheld. Both men were ordered to face civil retrials.
Daly's legal team are seeking to challenge that outcome.
The victims' relatives also want to go before the Supreme Court in an attempt to win the more punitive exemplary damages as part of their case. But Lord Justice Higgins rejected the appeals.
