Kernrechtsfrage
Whether supplementary connection fees based solely on the increase in building-insurance value violate the equivalence principle and the polluter-pays principle.
Extrahierter Entscheid
No. The court held that building-insurance value may generally serve as a permissible basis for connection fees, and the challenged increase did not create an obvious disproportionality in this case.
Extrahierte Begründung
The Federal Supreme Court reiterated that the equivalence principle and Art. 60a GSchG do not prescribe a specific calculation model. The building-insurance value is accepted for practical reasons, and only in exceptional cases of clearly atypical water use must it be corrected.
