The DPP has dropped all charges against ten people arrested following a water charge protest in Jobstown in Dublin in November 2014.
A charge of criminal damage remains in relation to one man who is due to appear in court again next month.
It follows the acquittals of Solidarity TD Paul Murphy and five others who were accused of falsely imprisoning Joan Burton and her adviser Karen O’Connell.
The former Tánaiste was attending a graduation ceremony when a large crowd of water charge protesters gathered where she was delivering a speech to graduates.
The prosecution claimed the women were effectively trapped in their car when they left the ceremony. Legal teams for the defence pointed to inconsistencies between some of the Garda testimony and the video footage presented to the court.
Six other defendants were due to stand trial today for charges arising from the same protest and another trial was due to take place next year.
But Sean Gillane, SC for the Director of Public Prosecutions, informed Judge Melanie Greally that the State was dropping the charges against all but one of the remaining accused.
Dylan Collins (20) of Bawnlea Green in Tallaght will be arraigned next month on one count of causing criminal damage to a Garda vehicle.
A large crowd gathered at the back of courtroom 19 at the Criminal Courts of Justice cheered and burst into applause as Judge Greally made her way back to her chambers. One woman sounded an airhorn before they left the building to address the media outside.
Peter Herbert (66) of Rossfield Park in Jobstown was among those whose charges were dropped today and he reiterated the group’s call for an independent and public inquiry into the entire prosecution.
Last year, a teenage boy (17) was found guilty by a judge in the Children’s Court of two counts of false imprisonment against Deputy Burton and Ms. O’Connell. He has already indicated his intention to appeal that decision, and there were further calls today for the conviction to be overturned.
