Kernrechtsfrage
Whether the public law appeal was admissible, including the request for declaratory relief.
Extrahierter Entscheid
The appeal was admissible in principle, but the request for a separate declaratory judgment was inadmissible because the tax dispute could be decided through a constitutive judgment.
Extrahierte Begründung
The decision was final and cantonally last instance, but declaratory relief lacked a protected interest where the tax liability could be examined directly.
