Kernrechtsfrage
Whether the appeal was admissible under Art. 84 BGG as a particularly important mutual legal assistance case involving secret information.
Extrahierter Entscheid
The case did not qualify as particularly important; no exceptional significance or serious foreign procedural defects were shown, so the appeal was inadmissible.
Extrahierte Begründung
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.
