The case concerned an extradition request by Brazil for the prosecution of the requested person in relation to aggravated sexual violence against a minor allegedly committed in Brazil between 2011 and 2018. The requested person challenged the judgment granting extradition, arguing that the Court of Appeal had failed to assess the risk of inhuman or degrading detention conditions in Brazil and should have requested information on the specific prison facility of destination, overcrowding, sanitary conditions and minimum living standards. The Italian Supreme Court held that the burden lies on the requested person to provide objective, precise, reliable and up-to-date evidence capable of raising a concrete risk of treatment incompatible with fundamental rights. General references to prison conditions, NGO reports or press articles were held insufficient, especially where the material relied upon did not contain specific and individualised information concerning the requested person’s likely detention. Since no concrete elements had been produced to undermine mutual trust between the States, the Court held that the Court of Appeal was not required to seek further information from the Brazilian authorities and dismissed the appeal.
