Kernrechtsfrage
Whether the Federal Supreme Court could hear the complaint under Art. 84 BGG in a tax information assistance case.
Extrahierter Entscheid
Yes. The transfer of information from the confidential sphere was undisputed, and the case raised a legal question of principle on the competent review authority.
Extrahierte Begründung
The Court held that jurisdictional allocation in international assistance is governed by domestic law; the case concerned the disputed boundary between mutual legal assistance and administrative assistance, which had not yet been settled and was of major practical importance.
