Question juridique clé
Whether public law appeal was admissible despite availability of a nullity appeal under tax-harmonization law
Solution extraite

Motifs extraits
The Court applied the transitional harmonization scheme by analogy to criminal tax matters and held that ordinary federal review of harmonized cantonal tax law was premature for obligations before 31 December 2000.
