Question juridique clé
Whether the appeal in international mutual legal assistance met the special importance requirement of Art. 84 LTF
Solution extraite
The appellant did not show that the case was particularly important; the matter did not justify Federal Supreme Court review.
Motifs extraits
The request concerned transmission of banking documents for three accounts and did not, by itself, raise a matter of special importance. The proportionality complaint did not create a question of principle, and the TPF did not depart from established case law allowing a broad interpretation of mutual assistance requests to avoid later requests.
