Kernrechtsfrage
Whether the fire brigade intervention costs for road closure and traffic diversion were lawfully charged to the vehicle owner under cantonal law.
Extrahierter Entscheid
Yes. The cantonal basis for charging the vehicle owner was undisputed, and the cost assessment was not shown to be arbitrary.
Extrahierte Begründung
Under cantonal fire-police law and the tariff ordinance, only obviously unnecessary or lightly incurred expenses are excluded. The lower court's findings that the vehicle caused relevant oil loss and that traffic regulation and road cleaning were necessary were not arbitrary.
