Question juridique clé
Whether A.________SA had standing to challenge the closure decision transmitting bank documents and interrogation records.
Solution extraite
A.________SA lacked standing because it was neither the bank account holder nor directly subjected to the coercive measures, and its mere implication in the documents was insufficient.
Motifs extraits
Standing in mutual assistance is limited to persons directly affected by coercive measures. Economic beneficiaries or third parties mentioned in the files may not challenge transmission of bank records or interrogation minutes, absent the exceptional situation where the minutes are functionally equivalent to account documents concerning a person entitled to appeal.
