Two senior Donegal gardaí and a Tusla area manager are to be recalled to the Disclosures Tribunal in light of new evidence of a previously undisclosed meeting between senior gardaí and Tusla.
Chief Superintendent Terry McGinn, Superintendent Eugene McGovern and Tusla Donegal manager Gerry Hone will be questioned about the meeting in Letterkenny on 29 November 2013.
This section of the inquiry was to finish today but will sit again on 23 October to hear more evidence.
The tribunal is examining contacts between gardaí and Tusla about whistleblower Garda Keith Harrison.
Further statements have been requested from Chief Superintendent James Sheridan, Assistant Commissioner Kieran Kenny and a Garda civilian analyst Eddie McGooey.
The inquiry heard that a new document was circulated yesterday relating to the meeting where Tusla referrals were discussed generally.
Garda Harrison is not mentioned in the minutes.
The meeting was attended by Chief Supt McGinn, Supt McGovern and four other gardaí along with Mr Hone, the Tusla area manager for Donegal.
Garda Harrison's lawyer, Mark Harty, said the tribunal does not have a proper explanation for why there was inertia from Tusla on the referral from the end of October to the end of February.
He said there was no clear starting point for the home visit in February and he needed to know more about the November meeting.
Tusla's lawyer, Paul Anthony McDermott, said the document was not disclosed as it had no relevance whatsoever to the tribunal's terms of reference.
He said Mr Hone would say the meeting was a general high level one on the need for more information from gardaí on referrals.
Lawyer for An Garda Síochána, Conor Dignam, said the document did not initially appear relevant but it was of interest now in light of evidence that had emerged.
He said it had been alleged that pressure was brought to bear on a social worker by her manager and now it was going one step further and the case was being made that pressure was brought by a more senior manager.
Mr Justice Peter Charleton also asked for an affidavit from the gardaí on the methodology of their searches.
The tribunal also heard about a second document containing the minutes of a Garda regional meeting held in Dundalk on 5 November 2013, when Ms McGinn updated gardaí on the Keith Harrison investigation.
There is no express mention of the Tusla referral in the minutes.
