Kernrechtsfrage
Whether the power increase of an existing antenna outside the building zone could be approved under the exception regime of the planning act.
Extrahierter Entscheid
The increase was reviewable under Art. 24 RPG, and the authorities could rely on renewed site-binding analysis for the change request.
Extrahierte Begründung
A prior permit binds only the concrete project. For a modification request, site binding must be reassessed; if it exists, the change may be allowed without eliminating the already lawful facility.
