Key legal question
Whether the appeal was admissible under Art. 84 BGG despite involving secret-domain information.
Extracted holding
The case did not qualify as a particularly important case, so the appeal was inadmissible.
Extracted reasoning
Although the request concerned information from the secret sphere, the appellant failed to show any special importance. No serious procedural defects or abuse were substantiated, the banking records were potentially relevant, and the case had no special foreign-policy significance.
