In the absence of a treaty between the States concerned, or where an applicable treaty does not provide for an assessment by the requested State of the existence of serious indications of guilt, the Italian judicial authority must not confine itself to a merely formal review of the documentation attached to the extradition request. Rather, it must ascertain that the request sets out the reasons why, within the framework of the requesting State’s procedural system, it has been considered probable that the requested person committed the offence forming the basis of the extradition. This requirement is satisfied where the competent judicial authorities have reconstructed in detail the time, place, manner of commission and underlying motives of the alleged criminal conduct, identifying the existence of multiple indicia of guilt in the results of police investigations, witness statements, and the findings of forensic medical examinations carried out on the victim’s body.
