A Genoa court handed out prison sentences totalling 102 years to 24 Italians found guilty of playing various roles in the rioting at the 2001 G8 summit in this port city.
The jail sentences handed to the anti-globalisation protestors ranged from five months to 11 years, the latter going to a 41-year old woman believed to belong to the Black Block movement of activists.
The ruling was the first sentence pronounced by Italian courts on the disturbances, which produced one death among protestors and have sparked considerable controversy ever since.
One of the 25 defendants was acquitted.
A group of anti-globalisation activists gathered outside the courtroom during the last stages of the trial and staged a minor demo which was watched closely by police.
One of the first reactions came from Northern League senator Roberto Castelli, who was justice minister at the time of the riots. ''Justice has been done. To complete the job we now have to discover the identities of the other Black Block members,'' he said.
Francesco Caruso, who was among the protestors in 2001 and who has since been elected to parliament on a Communist ticket, blasted the court ruling.
''It's a worrying repressive attack on all those who filled the streets of Genoa six years ago,'' he said.
The 2001 summit drew thousands of protestors to the Italian city, but most did not take part in the rioting.
