Kernrechtsfrage
Whether the complaint in public law matters was admissible against the Federal Administrative Court's interim decisions in a tax-assistance case.
Extrahierter Entscheid
The Federal Supreme Court lacked jurisdiction in this subject matter; the complaint was inadmissible.
Extrahierte Begründung
Under Art. 83 lit. h BGG, the Federal Administrative Court decides tax-assistance matters definitively, so the Federal Supreme Court cannot review even related interim procedural decisions. Data-protection objections do not create federal jurisdiction in this framework.
