Question juridique clé
Whether the municipality could charge non-resident owners a higher water connection fee than resident owners.
Solution extraite
No. The residence-based differentiation violated equality and could not be applied; the appellant owed only the 1% fee.
Motifs extraits
For connection fees, the cost of connecting a building to the water supply does not depend on whether the owner lives in the municipality. Since the system is financed largely through fees and local taxation already contributes to any residual costs, a tariff may not differentiate by the payer's residence where no objectively relevant reason exists.
