Italy's Supreme Court on Friday rejected an appeal by the Turin prosecutor's office to charge three men involved in a 2013 riot with terrorism.
The men were sentenced in May 2014 to two years and 10 months in prison for their roles in the May 2013 high-speed-train (TAV) riot in Chiomonte.
In December 2014, a Turin court of reexamination dismissed the accusation of terrorism, and the Turin prosecutor's office appealed that decision to the high court which made its ruling today.
So-called NO-TAV protests have frequently turned violent in recent years and there have also been some acts of sabotage on the line being built between Lyon and Turin.
