Key legal question
Whether C. had standing to challenge transmission as an economic beneficiary and mandator of bank accounts.
Extracted holding
No. A mandator or economic beneficiary is not personally and directly affected within the meaning of the MLA act; he may not litigate to protect clients' interests.
Extracted reasoning
The court held that C. did not show direct personal impact from the mutual assistance measures. His position as mandatary remained, in substance, that of an economic beneficiary acting for clients, which is insufficient.
