Kernrechtsfrage
Whether the appeal was admissible under Art. 84 BGG as an especially important case in MLAT matters involving secret information.
Extrahierter Entscheid
The case was not especially important; the appeal was inadmissible.
Extrahierte Begründung
Art. 84 BGG applies, but the appellants failed to show exceptional importance. Their criticisms of the request's factual basis and the nexus to the foreign proceedings merely challenged the lower court's application of settled case law and revealed no federal-law violation or extraordinary significance.
