Kernrechtsfrage
Whether the economically entitled co-appellants had standing to challenge the mutual legal assistance measure.
Extrahierter Entscheid
The appeal of the economically entitled persons was inadmissible because they were not account holders and therefore lacked standing.
Extrahierte Begründung
Under Art. 80h lit. b IRSG, only persons directly affected have standing; merely economic entitlement to the account is insufficient.
