Under the surrender regime provided for by the Extradition Convention between the Italian Republic and the Argentine Republic, it is sufficient that the Italian judicial authority ascertain, by way of a summary assessment, that the documentation accompanying the request is, in concreto, capable of substantiating—within the framework of the requesting State’s procedural system—the existence of evidence against the requested person. Accordingly, it is not permissible to raise issues concerning the merits of the investigations carried out by the requesting State (the Convention does not require the production of sources of evidence), nor, a fortiori, to question the evidentiary value of the material collected, which is to be assessed by the deciding State in accordance with its own procedural rules.
