Question juridique clé
Whether the municipality had a valid expropriation right from the zoning designation of the parcels as ZöBA.
Solution extraite
Yes. Under cantonal law, the expropriation right arises with the lawful zoning to the zone for public buildings and installations; the zoning became final and cannot be reviewed here.
Motifs extraits
The public-interest, necessity and proportionality review had to be raised in the planning procedure. Because the owner did not challenge the zoning revisions, the planning decision is final and binding in this compensation case.
