Anti-Austerity Alliance TD Paul Murphy is due back in court today with 15 others accused of falsely imprisoning the Tánaiste and her adviser during a water charge protest.
Four weeks in April 2017 have been provisionally set aside for their trials.
Joan Burton and her adviser Karen O’Connell were allegedly trapped in their car by water charge protestors while trying to leave a graduation ceremony in Jobstown in Dublin in November 2014.
Eighteen people have been sent forward for trial in connection with the incident.
Sixteen of them, including Anti-Austerity Alliance TD Paul Murphy and two of the party’s local councillors, are accused of false imprisonment - a charge that carries a maximum penalty of life in prison.
The Director of Public Prosecutions wants to split the protesters into four groups and hold separate trials.
The protestors want to know the reasons for doing so, and the DPP was due to write to them before the end of last month.
Their cases are due back before Dublin District Court this morning.
A block of four weeks next April have already been set aside for the trials.
