Donegal publican, Frank McBrearty Junior has settled all his claims with the State.
His lawyers met with state solicitors last week.
The claims, amounting to €1.5m, relate to malicious prosecution as well as wrongful and false arrest.
Some 47 High Court actions by members of the extended McBrearty family had been due to commence on October 18.
State lawyers conceded liability for damages to Mr McBrearty Junior in June last.
The Morris Tribunal found that members of the Gardaí attempted to frame 36-year-old Mr McBrearty and his cousin Mark McConnell for the murder of Richie Barron in October 1996.
Five pathologists have subsequently stated that Mr Barron died as a result of a hit-and-run accident.
