Key legal question
Whether the appeal was admissible under Art. 84 BGG as a particularly important mutual legal assistance case involving secret information.
Extracted holding
The case did not qualify as particularly important; no exceptional significance or serious foreign procedural defects were shown, so the appeal was inadmissible.
Extracted reasoning
Although secret information was involved, the appellants failed to show any ground under Art. 84(2) BGG. The case was neither unusually significant nor based on indications of violated fundamental procedural principles or serious defects abroad.
