Kernrechtsfrage
Whether the constitutional complaint was admissible despite the availability of a cantonal nullity action
Extrahierter Entscheid
The complaint was admissible because the only cantonal remedy would have been a nullity action limited to procedural defects and denial of hearing, which were not at issue.
Extrahierte Begründung
The challenged cost decision was rendered by the appellate court itself and was therefore a final cantonal decision; no relevant procedural defect or denial of hearing was alleged.
