Questione giuridica chiave
Whether the municipality's autonomy was violated by ordering rezoning of the built-up area into a suitable building zone.
Decisione estratta
No. The cantonal authorities could require zoning as a building zone because the area was suitable for building and already largely built up; refusing agricultural zoning was not arbitrary.
Motivazione estratta
The area was almost fully built over, with non-agricultural houses and a workshop, and agricultural use was neither existing nor foreseeable. A building zone would not create an unlawful small building zone because only existing built-up land was affected and any expansion would remain modest.
