Judge Frederick Morris has this evening granted costs to two witnesses, Katrina Brolly and Garda John Dooley ahead of its report of mistreatment in Garda custody.
Gda Dooley recently changed his evidence to the tribunal admitting he had abused Mrs Brolly and Mrs McConnell during interviews in 1996.
Judge Morris said: "It is true that there are some contradictions in the evidence but I am satisfied in no case has a suggestion been made to me that either of these two parties is deliberately attempting to mislead the tribunal or obstruct it in its work."
He added: "It is accepted that the evidence that they are giving is their honest belief of what transpired on the occasion."
The chairman said he would draw up a report based on the mini-module and then hear submissions from legal counsel for costs.
Judge Morris heard closing submissions in the sub-module in relation to the detention of Donegal sisters Mr Brolly and Roisin McConnell in Letterkenny Garda Station in December 1996.
Earlier today a former detective superintendent dismissed as outrageous claims he had told a garda to flash post mortem pictures at a woman during an aggressive interview designed to break her down.
Joseph Shelly, a retired detective superintendent, said Det Sgt John White was attempting to pass the blame onto senior officers for his own actions during interviews with two Donegal women in December 1996 in relation to the death of Richie Barron.
"He was there to establish the truth, he was a sergeant in the gardai he had experience, he knew what the regulations were, how he should conduct himself, that he didn't do it, chairman," Mr Shelly said.
"And he now comes to this tribunal and in this manner tries to blame me or John McGinley or somebody else is outrageous. He has to take responsibility for his wrongdoing. He shouldn't come in here and attempt to lay it off on somebody else."
Mr Shelly has refuted allegations by the suspended sergeant that he told him to use strident and aggressive interview techniques "to break" Ms Brolly and her sister Mrs McConnell during interviews on December 4th, 1996.
"The term wasn't used to break anybody, he was there to interview the person properly, in accordance with procedure to try and establish the truth if that was possible," he said.
The tribunal has heard the women were shown graphic pictures of the dead man, lights were flicked and they were told their children would be taken away by social services.
