Key legal question
Whether the US request was sufficiently complete under Art. 29 RVUS
Extracted holding
The request, together with the later supplement and plea agreement, provided enough facts for Swiss authorities to assess admissibility and the scope of assistance.
Extracted reasoning
The requesting state need not present a fully complete or contradiction-free case; it is enough that the request allows assessment of a mutual-assistance offence, refusal grounds, and the relation to the foreign proceedings. No obvious gaps or contradictions remained.
