Key legal question
Whether the constitutional complaint could also challenge the cantonal tax office and tax appeal commission decisions.
Extracted holding
The complaint was admissible only against the final cantonal decision; challenges to lower-instance decisions were not heard.
Extracted reasoning
Under Art. 86(1) OG, only final cantonal decisions are reviewable unless lower-instance rulings could not be raised before the last cantonal court, which was not the case here.
