Key legal question
Whether the constitutional complaint against a final cantonal decision on a municipal zoning amendment was admissible and whether the appellant was legitimized.
Extracted holding
The complaint was admissible in principle against the final cantonal planning decision, and the appellant had standing as co-owner of the affected parcel; challenges to lower-instance decisions were inadmissible.
Extracted reasoning
Planning decisions may be attacked by constitutional complaint under the planning act; standing follows from the appellant's direct property interest. However, only the last cantonal decision can be challenged.
