Key legal question
Whether the US request was sufficiently specific and based on a reasonable presumption of offense conduct
Extracted holding
Yes. The request adequately described the investigation, the suspected flow of funds, and the appellant’s alleged role.
Extracted reasoning
Under the treaty, the requesting state must set out the object, nature, and principal facts of the investigation, but need not prove the suspicions. Swiss authorities only refuse assistance for patent gaps, errors, contradictions, or abusive fishing expeditions.
