Question juridique clé
Whether the appeal was admissible under Art. 84 BGG as a particularly significant mutual legal assistance case.
Solution extraite
The case was not particularly significant within the meaning of Art. 84 BGG, so the Federal Supreme Court had no reason to enter into the appeal.
Motifs extraits
The dispute concerned only whether the lower court correctly denied the appellant standing. The lower court's reasoning followed settled case law and disclosed no federal-law violation.
