A Garda who was alleged to have leaked the Garda documents to the media that forced the resignation of Trevor Sargent TD as minister for state will not be prosecuted.
Garda sources have confirmed the Director of Public Prosecutions has decided not to press charges against the young female garda at the centre of the case.
It is unclear why the DPP made the decision not to prosecute and the office does not explaining its reasons.
However, it is understood the garda in question still faces an internal Garda inquiry into the matter.
As part of the investigation into the matter she was arrested in March and questioned at Lucan garda station. She was released without charge on that occasion.
Under the Garda Síochána Act, an officer can face a €50,000 fine or up to five years in jail for disclosing confidential information.
Mr Sargent stepped down in February after it emerged that he had written to gardaí about a constituent in north county Dublin who was facing criminal proceedings. He urged the investigating gardaí to drop criminal charges against constituent Dominic McGowan.
Mr Sargent wrote a number of letters to gardaí after Mr McGowan was attacked near his home at the Cardy Rock estate in Balbriggan in September 2007.
In one of the letters to gardaí, Mr Sargent said it would be “wholly inappropriate” to prosecute Mr McGowan, who he believed had only become involved in a public order incident after he tried to discourage other residents from damaging public property.
However, Mr McGowan was subsequently convicted and fined for a public order offence.
When the case came to court, Mr Sargent wrote again to gardaí in February of this year asking that the superintendent “keep an eye on the case”, as he was concerned for the safety of his constituent.
When the correspondence came to light in the Evening Herald, Mr Sargent tendered his resignation as minister of state for food and horticulture within hours, accepting that he had made an "error of judgment".
