Question juridique clé
Whether the mutual legal assistance request was sufficiently connected to the suspected securities-fraud investigation and not a prohibited fishing expedition.
Solution extraite
Yes. The bank records had a sufficient factual nexus to the U.S. investigation into alleged market manipulation and laundering of proceeds.
Motifs extraits
The request described concrete suspicious transactions, the appellants were economically linked to the relevant shares, and the timing of transfers and sales could relate to the alleged scheme. The Swiss court held that assessing whether the conduct was coordinated fraud was for the U.S. authorities, not the Swiss mutual-assistance judge.
