Case Law
Extradition granted only for offences satisfying double criminality (personal drug use excluded)
โ
Summary
Switzerland requested the extradition of the requested person for the enforcement of a final custodial sentence concerning drug-related offences and the unauthorised sale of medicinal products. The Italian courts had granted extradition only for drug trafficking and unauthorised pharmaceutical sales, while refusing it for possession of drugs for personal use because that conduct is subject only to an administrative sanction under Italian law and therefore fails the double criminality requirement. On appeal, the requested person incorrectly argued that extradition had also been granted for personal drug use. The Court of Cassation declared the appeal inadmissible, holding that the refusal concerning that offence had already become final and that the extradition order was limited to the offences for which double criminality was satisfied.

Granted with conditionsExtraditionSummary assessment of evidence in extradition proceedings under the European Convention on Extradition
โ
Summary
In extradition proceedings governed by the 1957 European Convention on Extradition, the Italian judicial authority, even where the applicable convention does not require a full assessment of serious indications of guilt, must carry out a summary assessment under Article 705 of the Italian Code of Criminal Procedure. Such assessment cannot, however, amount to a detailed review of the evidentiary framework, since the requesting State is not required to transmit the evidence itself, but only sufficiently precise factual allegations and an indication of the evidentiary basis supporting the accusation within the requesting Stateโs procedural system.

Reversal and remandExtraditionExtradition to Switzerland: summary assessment of evidence does not require full evidentiary disclosure
โ
Summary
The case concerned a Swiss request for prosecution extradition in relation to several aggravated robberies, committed and attempted, allegedly carried out with weapons against fuel stations, as well as firearms-related offences. The Court of Appeal of Bologna had refused extradition, finding that the material transmitted by the Swiss authorities did not allow even a summary positive assessment of the existence of serious indications of guilt. The Italian Supreme Court held that, under the European Convention on Extradition, the requesting State is not required to transmit the evidence itself, but must provide a sufficiently precise account of the factual and evidentiary basis supporting the alleged responsibility of the requested person. The Court found that the Swiss request contained an analytical description of the facts and identified categories of evidence, including telephone contacts, cell-site data, vehicles allegedly used by the suspects, video surveillance, victim statements and automatic vehicle monitoring. Since this was sufficient for the limited summary assessment required in extradition proceedings, the judgment refusing extradition was annulled and the case remanded to another section of the Court of Appeal of Bologna.

Summary
The case concerned a Swiss request for prosecution extradition in relation to several aggravated robberies, committed and attempted, allegedly carried out with weapons against fuel stations, as well as firearms-related offences. The Court of Appeal of Bologna had refused extradition, finding that the documents transmitted by the Swiss authorities did not allow even a summary positive assessment of the existence of serious indications of guilt. The Italian Supreme Court held that, under the European Convention on Extradition, the requesting State is not required to transmit the underlying evidence itself, but must provide a sufficiently precise account of the factual and evidentiary basis supporting the alleged responsibility of the requested person. In this case, the Swiss request contained an analytical description of the facts and identified categories of evidence, including telephone contacts, cell-site data, vehicles allegedly used by the suspects, video surveillance, victim statements and automatic vehicle monitoring. Since those elements were sufficient for the limited summary assessment required in extradition proceedings, the judgment refusing extradition was annulled and the case was remanded to another section of the Court of Appeal of Bologna.

Reversal and remandExtraditionExtradition: the Court must verify requirements for surrender and absence of grounds for refusal (without calculating the sentence to be served)
โ
Summary
It does not fall within the powers of the Court of Appeal to calculate the sentence to be served following the granting of extradition. The judicial review that judges are called upon to carry out, in the case of an extradition request, is in fact limited to verifying the existence of the legal requirements and the absence of grounds preventing the acceptance of the request, without being able to modify or adapt the foreign enforcement title. The determination of the sentence to be executed for the offences for which extradition is granted is an exclusive prerogative of the requesting State, entrusted to the institutional responsibility of that countryโs judicial authorities and not to those of the requested State.

Reversal and remandExtraditionExtradition to Switzerland partly granted: double criminality lacking for private-document forgery
โ
Summary
The case concerned a Swiss request for extradition from Italy for prosecution in relation to aggravated continuing fraud and forgery of private documents. The alleged conduct involved a fraudulent investment scheme based on representations concerning gold trading and the ownership of mines, supported by allegedly false documents and communications. The Court of Appeal of Bologna held that extradition could be granted only in part. Double criminality was satisfied for the aggravated fraud allegations, which corresponded to fraud under Italian law and were not time-barred. However, extradition was refused for the offences of forgery of private documents, because the corresponding Italian offence had been repealed. The Court also examined whether Italian proceedings concerning similar or related conduct barred extradition. It held that only proceedings concerning the same historical facts and the same injured parties could prevent extradition, not merely proceedings involving analogous conduct or the same general context. Since overlap was established only for one specific fraud allegation already under investigation in Italy, extradition was excluded for that fact alone. Pending Italian proceedings for different facts did not prevent a finding of extraditability, since any decision to postpone surrender or allow temporary surrender fell within the competence of the Minister of Justice at the execution stage. The Court therefore declared the conditions for extradition satisfied for the aggravated fraud offences, except for the fact already pending before the Italian judicial authority, and refused extradition for private-document forgery.
