Séamus McGrane, aged 60, of Little Rd, Dromiskin, Co Louth, was charged with membership of an unlawful organisation styling itself the Irish Republican Army, otherwise Oglaigh na hÉireann, otherwise the IRA, within the State between December 23, 2009 and May 13, 2015.
Mr McGrane was also charged with directing the activities of an unlawful organisation styling itself the Irish Republican Army on dates between December 23, 2009 and May 13, 2015 inclusive. Detective Sergeant Padraig Boyce said Mr McGrane made no reply to the charges.

Dónal Ó Coisdealbha, aged 23, of Abbeyfield, Killester, Dublin 15, was charged with membership of an unlawful organisation styling itself the Irish Republican Army.
Mr Ó Coisdealbha was also charged with possession of a component part of an improvised explosive device, namely a time and power unit also known as a TPU, at “the personal storage locker under the control of Dónal Ó Coisdealbha, at Protector Life Sciences, National University of Ireland, Maynooth, Co Kildare” under such circumstances as to give rise to a reasonable suspicion that he had not got it in his possession for a lawful purpose, on May 13, 2015.
Det Sgt Finbarr Hayes told the court that he arrested Mr Ó Coisdealbha at Irishtown Rd, and he had nothing to say in reply to the charges.
Mr Ó Coisdealbha was remanded in custody until Wednesday. Solicitor Kieran Conway, for Mr Ó Coisdealbha, told the court that he will be applying for bail on the next occasion.

Detective Garda Mark Benson told the court he arrested Mr Cahill at Cluneen, Manorhamilton, Co Leitrim last Friday and he made no reply to the charges.
When an application for bail for tomorrow was proposed on Mr Cahill’s behalf, solicitor Liam Mulholland, for the DPP, said tomorrow was a bad day for the gardaí because of the visit of Prince Charles to the State.
“The gardaí are extremely busy that day,” Mr Mulholland said.
