Key legal question
Whether the appeal is admissible under Art. 84 LTF in international criminal mutual assistance.
Extracted holding
The case does not qualify as particularly important; the appeal is inadmissible.
Extracted reasoning
Although secret information was at stake, the appellant did not show a sufficiently important case. The Court found no indication of serious procedural violations or major foreign defects, and the potential usefulness of the transcript made the request proportionate.
