Question juridique clé
Whether the appeal was admissible under Art. 84 BGG as a particularly important mutual legal assistance case.
Solution extraite
The case was not particularly important; no new fundamental legal question or serious procedural defect was shown.
Motifs extraits
The challenged order concerned bank records, but the Federal Criminal Court correctly applied the settled rules on time limits and bank-held correspondence. The appellant did not show a Swiss service address before the final order, and the bank-lagernd arrangement did not create a special case.
