Questão jurídica principal
Whether A.A. had standing to appeal the assistance order
Decisão extraída
A.A. lacked standing as he was not the account holder and only indirectly affected; his challenge was inadmissible except for the complaint about denial of standing.
Fundamentação extraída
Under the MLA rules, only persons personally and directly affected may appeal. Being the accused abroad is not enough when the measure concerns third-party bank accounts.
