Kernrechtsfrage
Whether the constitutional complaint was admissible despite the pending revision remedy under cantonal tax law.
Extrahierter Entscheid
The complaint was inadmissible because the taxpayers had to exhaust the revision remedy first, since it could raise the same procedural grievances.
Extrahierte Begründung
Under Art. 86 OG the cantonal remedies must be exhausted. Section 155(1)(b) StG allows revision for overlooked facts, evidence, or serious procedural violations, including denial of the right to be heard; therefore the hearing-violation complaints had to be raised in revision before a constitutional complaint.
