Question juridique clé
Whether the Japanese request was sufficiently reasoned under mutual assistance law
Solution extraite
Yes. The request identified the offences, their legal characterization, the suspected persons, and the purpose of tracing the proceeds of the offences.
Motifs extraits
The Court held that the request need not be overly detailed at the investigative stage; it is enough that it allows verification that the request is not manifestly inadmissible.
