Kernrechtsfrage
Whether the appeal could challenge only the refusal to revise the cantonal tax decisions under cantonal procedural law.
Extrahierter Entscheid
The federal appeal could address only the cantonal procedural-law issue concerning revision; the appellant failed to show arbitrary application of that law.
Extrahierte Begründung
For pre-harmonization tax period 2000, LHID art. 51 did not apply, so revision depended solely on cantonal procedure. A complaint about cantonal law requires a properly reasoned arbitrariness claim under Art. 9 Cst.; this was not done.
