Question juridique clé
Whether the mutual legal assistance appeal was admissible under Art. 84 BGG as a particularly significant case.
Solution extraite
The case did not raise a particularly significant issue; the appeal was therefore not admissible.
Motifs extraits
The complaint only repeated substantive objections already examined below and disagreed with the lower court's application of settled Federal Court case law. Such appellatory criticism does not make the case particularly significant.
