A Tusla social worker has told the Disclosures Tribunal that she did not apologise to Garda Keith Harrison and his partner Marissa Simms for her dealings with their family.
Donna McTeague said she did not apologise to them for the work she was doing, or for inviting them to an initial office meeting.
She also said she did not apologise for the later visit to their home.
The couple have alleged that Ms McTeague apologised to them for having to pursue the case.
Garda Harrison's lawyer, Mark Harty SC, said the language she used had been apologetic and that was perfectly reasonable.
Ms McTeague again said she did not say that.
She also denied the allegation that she had said at the end of the office meeting that a home visit was unlikely.
She also said that she had not suggested to Ms Simms that her superior had a personal relationship with a sergeant and that was why the home visit had taken place.
Ms Simms has told the tribunal she has no recollection of that but Garda Harrison has said he recalled Ms Simms relaying the conversation to him.
The tribunal is investigating contacts between gardaí and Tusla, the child and family agency, in relation to Garda Harrison.
Gardaí notified Tusla of child protection concerns in relation to the couple on the back of a statement made by Ms Simms in October 2013 which alleged that Gda Harrison had threatened her.
Ms McTeague said she had been told there was an argument between Garda Harrsion and Ms Simms, with alcohol and physical contact, and children were present.
Mr Harty said to Ms McTeague that the information was incorrect and that nowhere in Ms Simms's garda statement did it say that children had witnessed physical contact.
He asked whether that would affect her assessment of the case.
Ms McTeague said the fact that there was a disagreement involving alcohol with children in the house was sufficient to warrant progressing the case even if children had not witnessed it.
Tusla worker says Harrison and Simms agreed to visit
A Tusla social care leader told the tribunal that Garda Harrison and his partner agreed to a home visit when it was suggested to them.
The couple allege that the visit caused them huge distress and that it was influenced by senior gardaí.
Naomi Wallace took notes when a Tusla social worker met the couple at the agency's offices on 9 February 2014.
Ms Wallace said that both agreed to a further home visit when it was mentioned.
She said she did not get the feeling that the office meeting was final and that it represented the end of the case.
Ms Wallace said she did not recollect the social worker telling the couple at the end of the meeting that "that would be the end of it" as alleged by them.
Ms Wallace's notes record Ms Simms telling Ms McTeague that she was more than welcome to come.
Also today, a principal social worker at Tusla rejected an allegation that she had leaned on a colleague to organise the home visit.
Bridgeen Smith said she "refuted" the assertion and it was absolutely, categorically not the case.
She said her relationship with Sergeant Brigid McGowan was purely professional and they did not see each other outside of work.
She said it was an attack on her professional integrity to allege otherwise.
