Kernrechtsfrage
Whether the challenge to the zoning-plan decision was admissible by administrative appeal or only by public-law appeal.
Extrahierter Entscheid
Only public-law appeal was available; administrative appeal did not lie.
Extrahierte Begründung
The zoning plan did not contain a decision under federal administrative law; it merely allocated parcels to a zone, and the case involved a zoning-plan decision under the RPG.
