Question juridique clé
Whether the federal public-law appeal was admissible before cantonal approval of the zoning plan amendment
Solution extraite
The appeal was inadmissible because the required cantonal approval under planning law was still outstanding, so no final cantonal decision existed yet.
Motifs extraits
Nutzungspläne become binding only upon cantonal approval; the Obergericht decision was only an intermediate step in the planning process and could not be challenged at federal level before approval. Federal review must respect the cantonal approval authority and coordination requirements.
