The Justice Minister says the cancellation of 999 calls relating to domestic violence significantly falls below policing standards expected by the public.
Over 3,000 calls were cancelled between early 2019 and October last year.
While over a third were cancelled legitimately, so far it's been found that more than 600 calls were cancelled before there was an appropriate policing response.
Minister Heather Humphreys says the Garda Commissioner has assured her that a new process has been put in place "to ensure this never happens again".
"I'm particularly concerned that anyone experiencing domestic abuse and indeed anyone in a vulnerable position who gets the courage to seek assistance may not have received it", she said.
Commissioner Drew Harris has apologised to victims but Sinn Féin says the issue has damaged public trust in the 999 emergency response system.
The party is calling on the Commissioner to appear before the Oireachtas Justice Committee to answer further questions on the matter.
