Questão jurídica principal
Whether the appellants could rely on legitimate expectations to keep the former extended opening hours.
Decisão extraída
No protected expectation existed for indefinite future renewals of the extended-hours permit; the city could change the general regime.
Fundamentação extraída
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.
