An investigation into the mass recording of phone calls in Garda stations has found it wasn't lawful, but no criminal cases were significantly affected by it.
The Fennelly Commission says the recording of 999 and emergency related calls is good practice but legislation is needed to continue it.
The Government says the report reinforces its decision to undertake a root and branch review of Gardaí.
An Garda Síochána said it welcomed the fact Judge Fennelly found "no Garda system of snooping, spying or intrusion into private lives and certainly not of listening to solicitor/client calls."
In a statement, An Garda Síochána says it "will work with the relevant authorities on the recommended legislation on this matter."
"There will now be a detailed examination of the report and where any organisational issues are identified they will be addressed as quickly as possible."
