Rattigan (31), with a last address at Cooley Road, Drimnagh, has pleaded not guilty to the possession of heroin and possessing the drug for sale or supply on Hughes Road South, Walkinstown, Dublin, on May 21, 2008.
He has also pleaded not guilty to possessing two mobile phones at Cell 42, E1 Landing, Portlaoise Prison while an inmate at the prison on May 22, 2008.
The court spent much of the day hearing evidence relating to a Nokia 2630 phone which was taken from Anthony Cannon during the garda raid on the house on Hughes Road South.
It is the prosecution case that Rattigan used mobile phones to act as the "directing force" behind a €1m heroin deal from his cell in Portlaoise Prison.
The court has heard evidence that gardai who raided the house on Hughes Road South discovered five kilos of heroin valued at over €1m in a shed at the back of the property.
There was evidence that gardai also discovered a red and white Nokia phone alongside an electronic weighing scale in the shed.
Last week detectives gave evidence that Rattigan was lying on his bed talking on a mobile when they arrived to search his cell, and that he jumped up and threw a phone in their direction when they entered the cell.
There was evidence Rattigan attempted to grab a SIM card on the bed before he was handcuffed.
The non-jury court viewed CCTV footage of an object being thrown on to a landing at Portlaoise prison during the garda search of Rattigan's cell.
In March 2011, the Director of Public Prosecutions ordered that Rattigan's trial should be moved from the Circuit Criminal Court to the Special Criminal Court (SCC), which normally deals with terrorist offences, because the ordinary courts are "inadequate" to try the case.
The trial continues on Tuesday in front of presiding judge Mr Justice Paul Butler.
