Key legal question
Whether the Japanese request was sufficiently motivated under Art. 28 EIMP
Extracted holding
Yes. The request identified the criminal conduct, the persons involved, and the purpose of tracing funds; this was enough to rule out manifest inadmissibility.
Extracted reasoning
In mutual assistance, the request need only contain enough detail to verify admissibility; it need not prove the foreign case. The request adequately explained the alleged market manipulation and the need to trace proceeds.
