Key legal question
Whether the appeal met the special admissibility requirement of Art. 84 LTF in a mutual legal assistance case
Extracted holding
The case was not particularly important within the meaning of Art. 84 LTF, so the appeal was inadmissible.
Extracted reasoning
Although secret-domain information was involved, the appellants did not show a principle issue or serious procedural defect. Their complaints about arbitrariness, hearing rights, professional secrecy, and proportionality did not elevate the case to special importance.
