Key legal question
Whether the appeal was admissible under Art. 84 BGG as a particularly important case involving secret-domain information.
Extracted holding
The case involved transmission of information from the secret sphere, but the appellant failed to show a particularly important case; the appeal was inadmissible.
Extracted reasoning
Art. 84 BGG strictly limits access in mutual legal assistance matters. The court found no exceptional importance, no indication of a violation of basic procedural principles, and no serious defects in the foreign proceedings. The lower court had addressed the essential objections and relied on settled case law.
