The Morris Tribunal has begun to deal with allegations that some Gardaí were involved in hoax bomb finds and that Gardaí planted subversive paraphernalia and then retrieved them.
Counsel for the Tribunal, Peter Charleton, said two civilians said particular things had happened, while two Gardaí were saying that they did not.
Peter Charleton has been outlining statements from Gardaí in Buncrana referring to the Garda informer, Adrienne McGlinchey, as an "attention-seeker of little intelligence value".
The Tribunal has heard that the Garda informer alleged that two Gardaí killed the cattle dealer, Richie Barron, in Donegal six years ago.
The cattle dealer's death instigated a number of Garda inquiries which led to the establishment of the Tribunal.
In his opening statement, Counsel for theTribunal said the two Gardaí had failed to give an account of their movements on 14 October 1996, the night Richie Barron was killed.
He also said that Supt Kevin Lennon, who is in charge of that investigation, and Det Garda Noel McMahon were alleged to have conspired to plant guns and ammunition purported to be from subversives, and then report them as findings to enhance their reputations and promotion prospects.
Mr Charleton said the Tribunal would be over very quickly if people told the truth. But Peter Charleton claimed people had forgotten the truth.
He said many felt victimised and had been extraordinarily embittered as a result of events. Mr Charleton added that it was clear that people had lied with regard to every term of reference.
McBrearty family will not attend tribunal hearingsMembers of the extended McBrearty family from Raphoe, who made many of the allegations, will not be present.
The family has decided not to take up legal representation at the Tribunal unless its terms of reference are broadened and provision is made for their legal costs.
The McBreartys say they cannot afford legal representation at an inquiry where decisions on the awarding of costs will only be made at the end.
The Morris Tribunal is expected to sit for at least two years and the family says it cannot expect their counsel to work for nothing during that time.
The family also want the terms of reference of the Tribunal to be expanded to cover the role of the Minister for Justice, the Attorney General, the Garda Commissioner, the DPP and the Donegal State Solicitor.
The McBreartys say the Tribunal as it is currently structured cannot bring out the truth of what happened to them and why.
The family is alleging extensive harassment by Gardaí and they want the Tribunal to probe their claim that key people knew what was happening but did nothing to stop it.
