Kernrechtsfrage
Whether a constitutional complaint could directly challenge the 1999 valuation directive
Extrahierter Entscheid
The directive is a mere administrative ordinance and cannot be directly attacked by constitutional complaint; only the concrete tax assessment may be reviewed.
Extrahierte Begründung
Administrative directives are not binding legal norms for the tax courts in the same way as statutes; their legality is reviewed indirectly through the assessment decision.
