Key legal question
Whether the appeal met the admissibility requirements under Art. 84 LTF for mutual legal assistance cases.
Extracted holding
No. The case was not particularly important and the appeal did not raise any exceptional issue warranting federal review.
Extracted reasoning
The appellant mainly disputed proportionality and the potential utility of the documents, but such arguments concerned evidence assessment and application of settled law. Swiss authorities do not assess witness credibility or guilt in mutual assistance proceedings, and no abuse of the foreign request was shown.
