Questione giuridica chiave
Whether the appellants had standing to challenge the EBK's disclosure order.
Decisione estratta
All three appellants were admitted: Y. as account holder, X. as autonomous asset manager with power of attorney, and Z. because of his prior participation in the EBK proceedings and his connection to the account.
Motivazione estratta
The account holder is directly affected; a self-managed asset manager is close enough to the subject matter; and Z. was sufficiently involved given the prior administrative participation, board position, marriage, and power of attorney.
