Convicted murderer John Dundon has launched a High Court challenge against being allowed only screened visits at Portlaoise Prison.
The gangster says the sanction was imposed by the governor last April and is unfair and breaches his rights.
Dundon, of Hyde Road, Limerick, is serving a life sentence for the gun murder of 28-year-old Garryowen rugby player Shane Geoghegan in Limerick in 2008.
He was convicted two years ago by the non-jury Special Criminal Court on the basis that the shots were fired by a hitman acting on Dundon's behalf.
In his action, Dundon (33) seeks an order quashing the governor's decision that he cannot have any open visits that would allow physical contact.
Dundon is the subject of a restricted regime and is housed in a separate facility away from the main prison population. He claims the sanction is one of indeterminate duration.
He says no reasons are furnished supporting the governor's decision, and complains that the blanket imposition of screened visits is a disproportionate interference with his rights.
Dundon received prison sanctions after he was found to be in possession of mobile phones and accessories.
He wants the decision quashed and, in a judicial review process granted by Mr Justice Richard Humphreys on an ex-parte basis, he also seeks several declarations including that the governor has acted unreasonably and unfairly.
Judge Humphreys made the matter returnable to a date in February.
In 2013, Dundon was found guilty of Mr Geoghegan's murder. Evidence was given at the trial that he had planned to kill a man named John 'Pitchfork' McNamara, who lived near Mr Geoghegan.
Dundon ordered gunman Barry Doyle to shoot McNamara less than 48 hours before the rugby player was killed.
Hours after the shooting, Dundon rang rival criminal Philip Collopy to boast that McNamara was dead, but had then panicked when he found out that the wrong man had been shot.
