Question juridique clé
Whether the appeal in international mutual legal assistance met the requirement of a particularly significant case under Art. 84 BGG.
Solution extraite
The case was not particularly significant; the appeal was therefore inadmissible.
Motifs extraits
Although information from the confidential sphere was at stake, the applicants' arguments were plainly incapable of showing the unlawfulness of the assistance order. They mainly disputed evidentiary assessment, which is not admissible in mutual assistance proceedings, and even a grace period for the advance would not change the outcome.
