Question juridique clé
Whether the municipality's autonomy was violated by the cantonal court's review of supplementary connection fees
Solution extraite
Yes. The cantonal court misapplied the constitutional principles governing fee collection and improperly excluded supplementary fees in all comparable upgrade cases.
Motifs extraits
The municipality has considerable discretion in setting such fees. The challenged judgment interfered with that autonomy by substituting an incorrect abstract rule for the municipal regulation.
