As of 2007, only Paolo Persichetti, former member of the "Unità Comuniste Combattenti", among the 200 Italians involved in Court cases dealing with political violence requested by Italy, had been extradited (in August 2002). He was eventually sentenced to 22 years of prison. Minister Edouard Balladur signed Persichetti's extradition decree in 1994; it was validated by the "Conseil d'Etat" the following year. According to RFI radio station, the Perben-Castelli agreement was divided in three parts: all events before 1982 would be prescribed "except in case of exceptional gravity"; facts between 1982 and 1993 would be "examined on a case by case basis", in function of the European Convention of Human Rights (ECHR) principle and of the "conditions in which the trials took place in Italy".
