Key legal question
Whether the request for mutual assistance met the requirements despite the appellant's challenge to the Italian suspicion basis
Extracted holding
The request was sufficiently substantiated and Swiss courts did not have to assess guilt or the credibility of the foreign evidence.
Extracted reasoning
For assistance, the requesting state need not prove the offence; it must only set out the facts supporting suspicion. The Swiss court reviews only a prima facie nexus and not the merits of the criminal accusation.
