A retired Garda Superintendent and three active members are to stand trial at the Special Criminal Court.
Retired Superintendent Garda John Murphy (65), Garda Detective Aidan Stratford (50), Garda Manus Keane (46) and Garda Eoghan Clerkin (51) will be sent forward to the non-jury court following an investigation into alleged corruption.
The Director of Public Prosecutions has said that the ordinary courts are not adequate to deal with the matter.
The Garda National Bureau of Criminal Investigation has now brought 189 charges against the four defendants following the corruption probe.
John Murphy was previously charged with facilitation of a criminal organisation and colluding with a detective to deceive people out of money contrary to the Criminal Justice (Corruption Offences) Act 2018.
He has been charged with seven counts of bribery under the Criminal Justice (Corruption Offences) Act 2018.
The ex-senior officer also faces four common law charges for communicating with a serving member of An Garda Síochána in a manner intended to pervert the course of public justice from April 2016 to January 2018.
He and Garda Detective Stratford are accused of contributing to activities intended to facilitate serious offences by a criminal organisation from 2016 to 2021, contrary to Section 72 of the Criminal Justice Act 2006.
The pair also have the same additional charge under Section 71 of the Criminal Justice Act 2006, accusing them of conspiring to induce people by deception to part with money, from the start of 2018 until the end of the following year.
Detective Aidan Stratford also has another 170 charges, including disclosing confidential information or corruptly accepting a gift, inducement, or reward.
Defending counsel Anne Doyle BL pleaded for legal aid for her client, saying that the charges he faces are of a level of seriousness that would prevent him from being able to finance his own defence.
Ms Doyle said that her client earns €700 per week and has two dependents.
State solicitor Mark Donnelly objected, saying that the prosecution had only been furnished with a statement of means this morning and was of the view that there may be a property portfolio that was not included.
Judge Dowling said that the court was not in a position to deal with the legal aid application today as the statement of means was not “fullsome”.
Garda Clerkin is charged under the Prevention of Corruption Act with corruptly attempting to obtain a gift or inducement on 19 February 2018.
A separate firearms charge alleges he unlawfully possessed 33 rifle rounds and 73 rounds of 9mm ammunition at an address in west Dublin.
He is further accused of facilitating a serious offence by a criminal organisation between 12 January 2018 and 13 June 2019.
Garda Clerkin did not appear in court today. A sick note was submitted on his behalf. He also did not appear at a previous hearing for the same reason.
He was remanded on continuing bail to appear before Cloverhill District Court on the 18th of December for possible further charges, to have the book of evidence served on him, and to be sent forward for trial.
Garda Manus Keane is charged that on 13 November 2014, he, a serving member, disclosed confidential information which was likely to have a harmful effect.
Defending counsel, Anna Miskelly BL, applied for legal aid for her client to extend to two counsels, which the court accepted.
Judge Dowling agreed to send Stratford and Keane forward for trial on a date yet unspecified.
