Garda management will come under renewed pressure today, with a Policing Authority report expected to highlight a culture in the organisation to keep breath test figures high.

Not one garda has been disciplined over the bogus alcohol breath test scandal despite the force admitting it inaccurately recorded some 6.4m tests at one stage.

Senior gardai have denied they knew of the widescale falsification of alcohol breath test data, contradicting claims by rank-and-file gardaí that management applied pressure to inflate figures.

Justice Minister Charlie Flanagan has said he wants “all the skeletons” out of the Garda cupboards.

Acting Commissioner Donal Ó Cualáin has called on frontline members who claim they were pressurised by managers into faking breath test figures to “give names” of those responsible.

Rank-and-file gardaí have said the breath test scandal was “entirely” the fault of Garda management and warned they would not be “scapegoated”.

Garda Commissioner Nóirín O’Sullivan’s failure to deliver an internal audit report into 1m fake breath tests and fixed-charge notices has been blamed on “considerable difficulties” in gathering facts, several months after the scandal broke.

A TD says she has new evidence proving that Gardaí must have known about the true number of roadside breath tests three years ago.

Gardaí say they cannot give details as to how breath test data was inputted into the Pulse IT system, with a legal firm also stating it is unknown what level of oversight was in place higher up the chain.

There are renewed calls for action to be taken over the Garda breath test and court summons scandals.

Each and every station superintendant has been out on the beat and should be able to recognise bogus figures, writes Michael Clifford.

The Garda Commissioner has told the Policing Authority that consequences arising from the breath test scandal, including possible disciplinary action, will be considered in the coming weeks.

It is hoped the diagnosis of two highly aggressive cancers could be made a lot faster with a simple breath test.
