Kernrechtsfrage
Whether the constitutional complaint against the ordinance was admissible and the appellants had standing.
Extrahierter Entscheid
The complaint was admissible in principle because the ordinance restricted previously permitted use of public waters and the appellants were concretely affected users.
Extrahierte Begründung
A new restriction on prior common use counts as an interference with legally protected interests; abstract review still requires concrete potential use and impairment.
