Key legal question
Whether the appeal was admissible under Art. 84 LTF in international mutual assistance matters
Extracted holding
The case was not particularly important within the meaning of Art. 84 LTF, so the appeal could not be heard on the merits.
Extracted reasoning
Although the decision concerned secret-domain information, the facts, the amount involved, and the alleged procedural defects did not reveal a particularly important case; the foreign proceeding showed no political character or serious defect.
