A 22-year-old man has been given a two-and-a-half year suspended sentence for the criminal damage of a garda car at the Jobstown water charge protests in 2014.
Dylan Collins of Bawnlea Green, Tallaght, is the only person with a conviction in relation to the protests.
He pleaded guilty to throwing a brick at the marked garda car.
After his arrest he told gardaí he was wrong to do so and while he intended to damage the car he did not intend to hurt anyone.
Former tánaiste Joan Burton and her advisor Karen O'Connell had attended a graduation ceremony at An Cosan Education Centre in November 2014 when protesters surrounded their car, delaying them for three hours.
The court heard today that Collins threw the brick 15 minutes after Ms Burton left and it was not the prosecution’s case that he was involved in anything unlawful earlier.
When he was arrested Collins admitted what he had done and told Gardaí he was wrong and and had shown poor judgement.
Garda Darren Rooney from Tallaght garda station said he accepted that Collins had not intended to hurt anybody.
The court heard he has two children aged two and four and is due to marry his partner next year.
His barrister told the court Collins' father died when he was a child and that he had no role model to look up to.
The court heard he looks after his mother who is ill.
Judge Martin Nolan said Collins seems to have gotten carried away in the anarchy of the day.
He said there were a large number of people gathered who were behaving disgracefully.
He said he accepts that Collins is remorseful for what he did.
A total of 19 people were charged in relation to the protest.
A juvenile was convicted of falsely imprisoning the two women in the Children's court but the conviction was overturned on appeal.
Last June, six men, including Solidarity TD Paul Murphy, were found not guilty by a jury of falsely imprisoning the women following a nine-week trial.
Charges against a seventh man were dropped halfway through the trial.
In October, charges against ten of Collins' former co-accused were dropped.
