Kernrechtsfrage
Whether the appeal to the Federal Supreme Court met the special admissibility requirements of Art. 84 LTF in mutual assistance matters.
Extrahierter Entscheid
The case was not particularly important within the meaning of Art. 84 LTF, so the appeal was inadmissible.
Extrahierte Begründung
The alleged procedural irregularities concerned the Swiss mutual-assistance procedure, not a grave defect in the foreign proceedings; the attack on the TPF's formal requirements did not amount to excessive formalism, and no other ground of particular importance was shown.
