The political party Solidarity has described the not guilty verdict in the Jobstown trial as a stunning defeat of what they claim was an establishment plan to create a chill factor around protest.
Solidarity TD Paul Murphy, County Councillors Michael Murphy and Kieran Mahon, and three others Scott Masterson, Frank Donaghy and Michael Banks were found not guilty of falsely imprisoning Joan Burton and her adviser at a protest in 2014.
The party is calling for charges against all remaining Jobstown defendants to be dropped and said last year's conviction of a minor for false imprisonment should be overturned.
Mr Murphy called on the Justice Minister to initiate an independent public inquiry into the garda investigation of the Jobstown case, which he said should also examine any allegations of political interference.
However, Minister for Justice Charlie Flanagan said: "This case has now concluded and a verdict reached by the court. Both the courts and the DPP are independent in the exercise of their functions. I do not see any grounds for a public inquiry."
One of those found not guilty, Ciaran Mahon, said the protest at Jobstown was inspired by cuts and austerity.
The party said it is likely to be involved in many more spontaneous protests in the future.
Solidarity has called on all on the left to come together in a broad left platform at the next general election.
But Deputy Ruth Coppinger said Sinn Féin would have to rule out any coalition with Fianna Fáil, Fine Gael or Labour before they could become part of it.
Solidarity has also pledged to step up its campaign against the abolition of flat-fee bin charges.
