Question juridique clé
Whether an administrative court appeal was available, or only a constitutional complaint, for a cantonal tax period still within the cantons' adaptation period under the Tax Harmonization Act.
Solution extraite
Only the constitutional complaint was available; administrative court appeal under the harmonization act did not apply.
Motifs extraits
Because the tax period fell within the transitional period granted to the cantons for adapting their tax laws, the federal administrative court appeal route was unavailable.
