Questão jurídica principal
Whether the appeal met the special significance requirement under Art. 84 BGG and was admissible.
Decisão extraída
The case was not particularly significant; the appeal was therefore inadmissible.
Fundamentação extraída
Although bank information from the confidential sphere was involved, the appellant showed no concrete basis for a different result. The alleged future recall of documents in Liechtenstein was speculative and did not justify delaying the expeditious mutual assistance proceedings.
