Kernrechtsfrage
Whether the constitutional complaint was admissible despite the availability in principle of a harmonization-law appeal route
Extrahierter Entscheid
For a pre-2001 taxable event, the constitutional complaint remained available; no special circumstances justified opening the harmonization-law appeal route.
Extrahierte Begründung
The transitional regime under the Tax Harmonization Act kept conflicting cantonal law in force until 1 January 2001, and the 1999 transaction did not fall within an exception.
