Kernrechtsfrage
Whether the appellants had standing to challenge the assistance measure.
Extrahierter Entscheid
Yes. The planned testimony concerned very specific account-related information and had the practical effect of a transfer of banking records; the appellants were personally and directly affected.
Extrahierte Begründung
Under the EIMP and OEIMP, account holders are directly affected by information concerning their accounts. Although the documents had already been transmitted, the requested testimony would add detailed, directly usable information about account management and operations.
