The case concerned a requested person subject to an extradition request from Switzerland for drug trafficking and aggravated money laundering. The Court of Appeal of Ancona had ordered pre-trial custody in prison, relying essentially on the seriousness of the alleged offences and on a presumed flight risk. The appellant challenged the order, arguing that the court had failed to provide concrete reasons for the existence of a flight risk and had not assessed the adequacy of the custodial measure, including in light of her personal and family circumstances. The Supreme Court of Cassation held that precautionary measures must remain adequate and proportionate throughout their application and that the lower court’s reasoning was merely assertive and silent on adequacy. It therefore annulled the order and remanded the case to the Court of Appeal of Ancona for a new assessment, including possible substitution with house arrest.

Extradition and non-recognition of pre-trial detention served abroad by the requested person in connection with the same extradition request: in Italy it is not possible to aggregate periods of detention served abroad pursuant to a decision of a foreign judicial authority; any such claim must instead be raised before the requesting authority that sought extradition from Italy (should the requested person be extradited).

The annulment with remittal (reversal and remand) of the judgment deciding on the extradition request does not directly affect the custodial measure ordered in connection with it, given the autonomy between those decisions, as confirmed by Article 714(4) of the Italian Code of Criminal Procedure, which provides for a time limit on the duration of the measure linked to the completion of the extradition proceedings.
