The Disclosures Tribunal has heard that lawyers for Noirin O’Sullivan advised that Maurice McCabe should be challenged on his motivation for making complaints against senior gardai.
The Tribunal is currently examining whether the then Garda Commissioner relied on false allegations of abuse to discredit the Garda Whistleblower at the O’Higgins Commission.
AnnMarie Ryan from the Chief State Solicitor’s Office told the tribunal she thought it was very normal for Counsel to ask for background information on someone who had "changed overnight".
The Tribunal heard that Commissioner O’Sullivan was not present at meetings with Counsel, but that her liaison was asked to get firm instructions from the Commissioner.
Ms Ryan said she expected to have a consultation with the Commissioner on the matter, and that Counsel were ready to meet with her over a weekend, but it didn’t happen.
