The Government has opposed a Fianna Fáil bill proposing to give the Policing Authority power to dismiss gardaí and have greater oversight of the Garda Commissioner.
The Bill was introduced by Fianna Fáil's justice spokesperson in the Dáil last March, following the announcement by An Garda Síochána of 950,000 false breath tests.
Since then, the figure has risen to 1.85 million.
During Private Members' time in the Dáil tonight, Deputy Jim O'Callaghan said something needed to be done to change how An Garda Síochána operates.
The Fianna Fáil deputy said that under the current legislation, there was no obligation on An Garda Síochána to inform the Policing Authority about the audit into the false breath tests across the country.
His bill proposes to introduce an obligation on gardaí to inform the Policing Authority on any matters that require an internal review in the force.
The bill also seeks to give power to the Policing Authority to dismiss a member of the force, which he said was the only way that significant reform would happen.
It also seeks to give the authority the power of oversight of the Garda Commissioner and power to the Garda Inspectorate to enter and review any station without giving prior notification.
Minister for Justice Charlie Flanagan opposed the bill.
The fundamental difficulty with it, according to Minister Flanagan, was that the Commission on Future Policing in Ireland, established earlier this year, was examining of all aspects of policing in Ireland including the Policing Authority.
The final report is due in September.
"In my view it would be far better to hear from the authority and to then consider what legislative changes are required", he said.
