A trial date has yet to be set for Anti-Austerity Alliance TD Paul Murphy on charges relating to a protest in Tallaght in 2014 during which Tánaiste Joan Burton and her assistant were detained in her car.

Mr Murphy, 32, with an address at The Copse, Woodpark in Ballinteer appeared at Dublin Circuit Criminal Court along with 18 others, some facing charges of false imprisonment and violent disorder.

His defence team requested the case be adjourned for mention to allow recent correspondence from the State to be considered.

They said they had replied to the Director of Public Prosecutions on Friday and were awaiting a response.

The case of most accused people was adjourned to 3 May while a warrant was issued for Dylan Collins, 20, of Bawnlea Green, Tallaght who failed to show up in court.

Among the group of accused are Dublin Councillor Kieran Mahon, 38, of Bolbrook Grove, Tallaght and AAA Councillor Michael Murphy, 50, of Whitechurch Way, Ballyboden.

Another accused, Thomas Kelly, 33, of Cushlawn Dale, Tallaght, was remanded in his absence after he did not come to court because he had started a new job.

His counsel asked Judge Melanie Greally for leniency as she said her client had attended court on all occasions and the court heard gardaí were not seeking a warrant on the condition that Mr Kelly's defence team ensure he is notified of the adjourned date.

Judge Greally said Mr Kelly had "seriously underestimated" his need to attend court but said given the "generous attitude of the prosecution" she would remand him in his absence to the same date as his co-accused.

Antoinette Kane, 23, of Cloonmore Park, Jobstown, Tallaght, who is due to have a baby in two weeks was not present in court and Colman Fitzgerald SC, defending, said he had been unable to take instruction from her.

She was remanded on continuing bail until 3 May.

The Tánaiste and her political advisor had been attending a graduation ceremony at An Cósan in Jobstown on 15 November 2014 and were detained in a car when they tried to leave.

The court heard they arrived at around midday but that a group of protesters encroached on them and gardaí as they were going from An Cósan to St Thomas's Church about 100m away.

It is alleged Ms Burton and her advisor Ms O’Connell were detained for about three to four hours.
