Kernrechtsfrage
Whether maintaining parcel no. 648 in the AP-EP zone violated municipal autonomy or was arbitrary.
Extrahierter Entscheid
The cantonal authorities did not overstep their review power or act arbitrarily by keeping the existing public-facility zoning, because no concretely realizable alternative school location existed yet and the public interest in the school remained current.
Extrahierte Begründung
The school had been in continuous use since the 1970s, the planned relocation was still too uncertain, and the authorities were entitled to adapt planning to the existing situation without substituting their own assessment for the municipality's.
