Question juridique clé
Which appellants were entitled to challenge the disclosure measures?
Solution extraite
Only the account-holding companies, and possibly those directly affected by the witness transcript, had standing; the economically beneficial owner and other accused persons lacked direct personal concern.
Motifs extraits
Under Art. 80h lit. b IRSG and Art. 9a IRSV, only the bank account holder is directly affected by bank record production. Mere beneficial ownership is insufficient absent extinction of the legal entity. Accused status abroad does not expand standing unless direct personal impact exists.
