Key legal question
Whether the appeal was admissible and the appellant had standing to challenge the MLA measures
Extracted holding
The appeal was admissible only in part; standing existed only for documents directly concerning accounts or relations held by the appellant, not for third-party records or search materials.
Extracted reasoning
Under the MLA rules, only persons directly affected by coercive measures may appeal. The appellant was not entitled to challenge documents concerning accounts held by banks or third parties, nor materials seized in the search of F.________SA, and could not appeal in the interest of law or to protect third parties.
