Question juridique clé
Whether the mutual legal assistance request was too incomplete to be admissible
Solution extraite
The request, supplemented by later explanations and a plea agreement, contained enough information to assess the existence of an assistable offence and possible refusal grounds.
Motifs extraits
Authorities in the requesting state need not present a complete, contradiction-free case; the Swiss authority only needs sufficient facts to assess dual criminality, refusal grounds, and scope. No obvious gaps or contradictions remained after supplementation.
