Kernrechtsfrage
Whether the water connection fee had a sufficient formal legal basis and complied with constitutional requirements.
Extrahierter Entscheid
The concessions contract, approved by the municipal assembly, had sufficient legal quality as a formal-law equivalent, but it could not justify a fee structure including profit; the matter required reconsideration of the fee under cost and equivalence principles.
Extrahierte Begründung
The contract defined liable persons and object sufficiently, yet Art. 16(2)(d) allowed economic return. That excluded reliance on cost-covering principles alone for the individual connection fee. The lower court had not checked separate accounting and allocation by fee category.
