Question juridique clé
Whether the transmission of the appellant's bank records was disproportionate and therefore impermissible mutual assistance.
Solution extraite
The records were potentially relevant because they could clarify the motive and possible beneficiaries of the alleged offences; no broader disclosure than requested was ordered.
Motifs extraits
In mutual assistance, documents may be transmitted if they may relate to the suspected offence and are not clearly irrelevant. Bank documents may be relevant to show the perpetrator's motives and the circumstances of the offence, including who may have been benefited.
