Key legal question
Whether the appeal against the mutual legal assistance decision was admissible without a particularly important case under Art. 84 LTF.
Extracted holding
The case was not particularly important and raised no question of principle, so the appeal was inadmissible.
Extracted reasoning
Document transfer concerned a specific bank file only; alleged procedural flaws, incorrect facts, and issues of specialty did not elevate the matter to a case of special importance.
