Kernrechtsfrage
Whether the public law appeal was admissible against the cantonal judgment, especially regarding evidentiary complaints that could be raised by reform appeal.
Extrahierter Entscheid
The evidentiary and right-to-be-heard complaints were inadmissible because the alleged violation of federal evidence law had to be raised in the parallel reform appeal; the public law appeal is subsidiary.
Extrahierte Begründung
The court applied the principle of absolute subsidiarity and held that the right to evidence under federal law is protected by Art. 8 CC, making the public law appeal unavailable for those complaints where a reform appeal was possible.
