Kernrechtsfrage
Whether the Swiss authority engaged in an impermissible fishing expedition by extending the request to the appellant's accounts at bank X.
Extrahierter Entscheid
No. Once the request and the execution revealed a relevant banking relationship, the authority could extend the search to other accounts of the investigated persons without violating federal law.
Extrahierte Begründung
The initial request described the appellant's role and the need to trace financial flows and proceeds of the offence. The extension was therefore a proportionate interpretation of the request and not an ultra petita measure.
