Reports emerge in the media about the snooping conducted on the two reporters' phone records.
The revelations prompt condemnation from the National Union of Journalists. Concerns are also expressed by Transparency International and Digital Rights Ireland.
Health Minister Leo Varadkar describes the revelations of snooping by GSOC as "a little bit odd and sinister" and "an infringement on freedoms".
Amnesty International calls for the law to be changed to introduce judicial supervision.
Justice Minister Frances Fitzgerald signals a review will be conducted within her department. It will look at the laws allowing An Garda Síochána, GSOC, the Defence Forces and the Revenue Commissioners to access the phone and email data of private individuals.
Public Expenditure Minister Brendan Howlin says that while a body such as GSOC is necessary, press freedom is a "fundamental pillar of our democracy".
Taoiseach Enda Kenny issues a stinging rebuke of GSOC's actions. He also says it may be appropriate to reform the legislation granting GSOC its snooping powers.
Ms Fitzgerald announces the review will no longer be conducted within her department, but by former chief justice John Murray.
He is to report within three months. The review is limited to the rules surrounding the accessing of the phone and internet records of journalists.
The Irish Council for Civil Liberties welcomes the move but says it is just "a first step".
It says the law as it is applied to the wider public must also be reviewed.
