Questão jurídica principal
Whether the appellants had standing to challenge the assistance measure.
Decisão extraída
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.
Fundamentação extraída
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.
