Despite officially attending to discuss the Policing Authority, the Garda Inspectorate, and other matters, Ms O’Sullivan is also expected to face questions over whether she had any role in the latest allegations.
News of the likely questioning came as Tánaiste and Justice Minister Frances Fitzgerald came under growing pressure to extend the judge-led inquiry into whistleblower allegations by Supt Dave Taylor that he was part of a campaign to discredit Maurice McCabe following his separate whistleblower revelations.
Speaking after Trevor Collins, solicitor for another whistleblower Keith Harrison, told RTE Radio’sprogramme his client’s concerns must be included in the six-week inquiry led by retired High Court judge Iarfhlaith O Neill, Ms Fitzgerald stressed she cannot comment on individual protected disclosure cases
Fianna Fáil justice spokesman Jim O Callaghan said all of the claims should be investigated, saying “if we’re now going to have an inquiry into whistleblowers then all of them should be included in the inquiry”.
Meanwhile, Ms Fitzgerald has said she was open to using modern technology to clone former Garda commissioner Martin Callinan’s mobile phone SIM card in order to clarify whether he or others had any knowledge of the alleged campaign against Sgt McCabe.
Responding to calls from Labour leader Brendan Howlin for the move to be considered, the justice minister said while she cannot comment on individual cases “it’s open to the judge to comment where questions of evidence may or may not arise”.
