A new report into the exaggeration of breath test figures has found an extra 400,000 cases, bringing to number to almost two million.
The Policing Authority has asked independent consultants Crowe Horwath to examine the breath test debacle, as well as the errors in Fixed Charge Penalty Notices.
It was originally suggested that one million false breath tests were recorded.
The report has also found that Garda management did not respond to the breath test problem appropriately.
The authority says that top Garda management is responsible for serious failures in governance and supervision that saw the breath test and fixed charge notice scandals go unchecked.
Chairperson Josephine Feehily wouldn’t be drawn on whether she wanted to see disciplinary action, but said she wanted a response from the acting Garda Commissioner.
"He deserves an opportunity to reflect on what we are saying here today. I want him to consider the points I'm making and come to our meeting in December with a response."
