Question juridique clé
Whether the appellants qualified as uninvolved third parties under the US mutual assistance treaty.
Solution extraite
They did not qualify as uninvolved third parties because there was a direct factual connection between their accounts and the suspected offenses.
Motifs extraits
A real and direct link to the offense is sufficient to exclude third-party status; the accounts were tied to transactions involving persons implicated in the US investigation and to suspect funds.
