Questão jurídica principal
Whether the federal appeal was admissible under Art. 84 LTF in international mutual assistance matters
Decisão extraída
The appeal was inadmissible because, although secret-domain information was involved, the appellants failed to show any particularly important case, fundamental violation, or serious defect in the foreign proceedings.
Fundamentação extraída
Art. 84 LTF requires not only secret-domain transmission but also a particularly important case; under Art. 42(2) LTF the appellants had to demonstrate this, which they did not.
