An email informing then justice minister Frances Fitzgerald of an issue with the Garda commissioner's legal strategy at the O'Higgins Commission appears to have been "wiped from history", a lawyer for the Disclosures Tribunal has said.
The email by Department of Justice assistant secretary Michael Flahive on May 15, 2015, was not included in a briefing pack for the minister ahead of a crunch meeting with Nóirín O'Sullivan the following year.
Tribunal counsel Kathleen Leader BL said: "It would appear one way or another that the information that was transmitted to the minister on May 15, 2015, has been wiped from history in relation to this particular briefing."
Ms Fitzgerald's then-private secretary, Chris Quattrociocchi, told the tribunal he couldn't explain why the information was not included.
The emergence of the email last November sparked a major controversy which almost toppled the Government. A general election was only avoided after Ms Fitzgerald resigned.
Ms Fitzgerald is due to give evidence at the tribunal today.
