Kernrechtsfrage
Whether the appeal met the admissibility requirements of Art. 84 LTF for an international mutual assistance case
Extrahierter Entscheid
The case was not particularly important within the meaning of Art. 84 LTF; the appeal was therefore inadmissible.
Extrahierte Begründung
Although secret information was involved, the appellant did not show a particularly important case. The proportionality and specialty arguments did not establish a serious defect, and new arguments could not be raised for the first time before the Federal Supreme Court.
