Up to 1,000 people gathered earlier outside the Central Bank in Dublin in support of those charged in connection with a water charge protest in Jobstown.
Tánaiste Joan Burton and her Special Advisor were unable to leave their car after attending a function last November.
The protesters marched from the Central Bank around College Green and up the South Quays to the Courts of Criminal Justice on Parkgate Street.
Meanwhile, United Left Alliance TD, Joan Collins, has been summonsed to appear in court in connection with alleged public order offences.
13 other people have been arrested in connection with the protest against the installation of water meters in South Dublin on 20 April 2015.
The Dublin South Central politician was taken to Terenure Garda Station and later released without charge. A file was sent to the Director of Public Prosecutions.
In a statement, the United Left Alliance TD said that she and 12 others had been summonsed to appear in court in connection with the protest.
Ms Collins' summons alleges she was acting in a manner contrary to the Criminal Justice Public Order Act.
It also alleges she was loitering in a public place which gave rise to a reasonable apprehension for the safety of persons and property and failed to comply with the direction of a member of the gardaí.
Ms Collins is due before the Courts of Criminal Justice on 2 November, the same day and the same court as 27 other people - including Socialist Party TD Paul Murphy and two South Dublin County councillors, Kieran Mahon and Mick Murphy.
They face charges of falsely imprisoning the Tánaiste and her special advisor in Jobstown, Tallaght at a different protest last November.
