Kernrechtsfrage
Whether splitting the building permit proceedings into separate steps was unlawful
Extrahierter Entscheid
The split procedure was not shown to be arbitrary and did not justify annulment of the later permit steps.
Extrahierte Begründung
Art. 22 RPG does not itself require a single procedural act. Any defect from splitting was cured because the whole project was eventually finally authorized, and the appellants did not show that their procedural position or the authorities' review powers were actually restricted.
