Kernrechtsfrage
Whether the appeal was admissible under Art. 84 LTF as a particularly important case in mutual assistance matters.
Extrahierter Entscheid
The case was not particularly important, so the appeal could not be heard on the merits.
Extrahierte Begründung
The lower court had applied established Federal Supreme Court case law on factual description, double criminality, and the usefulness of the requested bank records. No procedural principle was shown to have been violated and no question of principle arose.
