Key legal question
Whether the transmission of bank documents to Italy complied with the requirement of sufficient relevance and proportionality.
Extracted holding
The documents had a sufficient objective link to the foreign criminal proceedings and could potentially advance them; the request was not an inadmissible fishing expedition.
Extracted reasoning
Transfers into the appellant's accounts came from companies linked to the investigated person and could clarify suspicious flows and the origin of funds. The foreign authority needed only to render the suspicion plausible, not prove the offences.
