Kernrechtsfrage
Whether public law appeal was admissible despite availability of a nullity appeal under tax-harmonization law
Extrahierter Entscheid
Because the relevant source tax related to a pre-2000 obligation, the nullity appeal under Art. 61 LHID was not open; the public law appeal was therefore admissible.
Extrahierte Begründung
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.
