Kernrechtsfrage
Whether the mutual-assistance appeal satisfied the admissibility requirements of Art. 84 LTF as a particularly important case.
Extrahierter Entscheid
The appellant did not show a particularly important case; no elementar breach of procedural principles was established.
Extrahierte Begründung
Art. 84 LTF must be applied restrictively. The appellant failed to substantiate, as required by Art. 42(2) LTF, why the case involved a serious procedural violation or grave foreign deficiencies.
