Questão jurídica principal
Whether the appeal against the mutual legal assistance decision was admissible under Art. 84 LTF as a particularly important case.
Decisão extraída
The appeal did not show a particularly important case; the strict admissibility requirements of Art. 84 LTF were not met.
Fundamentação extraída
The appellant merely raised generic objections about fiscal fraud, speciality, the rogatory request, and dual criminality, without demonstrating any serious procedural violation or grave defect abroad. The lower court's reasoning did not depart from settled case law.
