Questione giuridica chiave
Whether the administrative appeal was admissible and the constitutional complaint excluded
Decisione estratta
The administrative appeal was admissible because the dispute concerned the implementation of binding federal harmonization law; the constitutional complaint was inadmissible.
Motivazione estratta
Article 69 StHG applied directly from 1999 in the cantons that had switched to the new system, so the case concerned harmonized federal law, not purely autonomous cantonal law.
