Key legal question
Whether the appeal in mutual legal assistance proceedings raised a particularly important case under Art. 84 BGG.
Extracted holding
The case was not particularly important, so the appeal was not admissible.
Extracted reasoning
Although bank information from the protected sphere was involved, the Court found no reason to depart from earlier judgments in the same matter and no conflicting decisions. The proportionality objection to handing over the bank documents also followed settled case law.
