Question juridique clé
Whether the subsidiary constitutional complaint was excluded because an ordinary public-law appeal was available
Solution extraite
The subsidiary constitutional complaint was unavailable because the case fell within the ordinary public-law appeal route under the Tax Harmonization Act and the Federal Tribunal Act.
Motifs extraits
The contested final cantonal decision concerned a matter governed by the Tax Harmonization Act and was therefore directly open to the public-law appeal; this excludes subsidiary constitutional review.
