Kernrechtsfrage
Whether the appellants could rely on legitimate expectations to keep the former extended opening hours.
Extrahierter Entscheid
No protected expectation existed for indefinite future renewals of the extended-hours permit; the city could change the general regime.
Extrahierte Begründung
The 2002 assurance covered only the initial permit framework, not a guarantee against later regulatory changes. Repeated annual renewals did not freeze the legal situation.
