Former Fine Gael minister Michael Lowry is applying to the circuit court to have four summonses relating to the alleged filing of incorrect tax returns struck out.
A hearing is taking place at Nenagh Circuit Court regarding the summonses which allege that the independent TD Mr Lowry (60) of Glenreigh, Holycross, Co Tipperary, knowingly filed incorrect tax returns on October 31st, 2003, and on August 3rd, 2007.
Mr Lowry was sent forward for trial from the district court to the circuit court earlier this year.
At Nenagh today, Patrick Treacy, SC for Mr Lowry, said he was asking the court to strike out the proceedings against his client.
Judge Thomas Teehan has been hearing legal debate on the case from Remy Farrell SC, prosecuting, and Mr Treacy.
Mr Lowry arrived at the courthouse in Nenagh at about 10.15am. After entering the building alone, he consulted with his legal team before the hearing began before Judge Teehan.
The judge is also due to give a ruling on an application made by the prosecution in July to have the case moved from Co Tipperary to Dublin.
The hearing continues this afternoon.
