Kernrechtsfrage
Whether the requested transmission of seized documents violated proportionality
Extrahierter Entscheid
The documents had a sufficient prima facie connection to the Italian investigation and were not manifestly useless; the proportionality objection failed.
Extrahierte Begründung
In mutual legal assistance, the requesting state need only show a plausible link between the documents and the criminal inquiry. Swiss authorities conduct only a limited review of potential utility and need not reassess the merits of the foreign investigation.
