Six protesters were acquitted of charges of false imprisonment
Criminal charges are set to be dropped against the remaining five people due to stand trial over the Jobstown protest.
Earlier this year, six other protesters including the Solidarity TD Paul Murphy were acquitted of charges of false imprisonment.
The case related to an anti-water charges protest, during which it was claimed the then-Tánaiste Joan Burton and her assistant were trapped in their car.
The men's solicitor Michael Finucane says the Director of Public Prosecutions (DPP) confirmed the decision in a letter to him.
"The DPP has confirmed a nolle prosequi is to be entered on the next court date in respect of the charges facing my clients.
"Essentially that means the prosecutions are being discontinued".
A teenager was the only person to be convicted in relation to the protest.
He was found guilty of false imprisonment at the Children's Court.
Speaking on TV3's The Tonight Show, Deputy Paul Murphy claimed there were now real questions about that conviction.
"He was convicted on the basis of standing in Joan Burton's way momentarily, and 'Joan will you talk to us? How is austerity impacting on you'?
"He was convicted of false imprisonment on the same evidence that was thoroughly discredited in front of a jury".
