Questão jurídica principal
Whether the municipal tariff provided a sufficient legal basis for a special water connection fee for swimming pools.
Decisão extraída
Yes. The fee was based on a duly approved municipal regulation authorized by cantonal law, and the special tariff for pools remained within the delegated framework.
Fundamentação extraída
Cantonal law allowed municipalities to choose an alternative basis of calculation; the separate treatment of free-standing pools was compatible with the statutory scheme.
