Questão jurídica principal
Whether the city fee schedule provided a sufficient legal basis for the sports-facility use fee
Decisão extraída
Yes. The municipal fee schedule was a formal law and § 60 sufficiently defined the fee payers, subject matter, and main criteria for setting the fee.
Fundamentação extraída
For public charges, the formal-law requirement is satisfied if the law determines the circle of payers, the object, and the main elements of assessment. Benutzungsgebühren may be more broadly delegated where legality can be reviewed through cost-covering and equivalence principles.
