Key legal question
Whether the appeal was admissible under Art. 84 BGG as a particularly important case in mutual legal assistance.
Extracted holding
The case was not particularly important, so the appeal was inadmissible.
Extracted reasoning
Although secret information was involved, the appellant showed no legal question of principle or serious procedural defect. The prior decision on standing for a merely economically entitled person raised no new issue, and the factual finding that beneficiary status in the liquidation proceeds was unproven was not objectionable.
