Questione giuridica chiave
Whether the administrative appeal was admissible against the zoning-plan decision and whether constitutional complaints were subsidiarily available.
Decisione estratta
Administrative judicial review was available for the RPG-based challenge; issues based solely on cantonal law or unsupported constitutional claims were not admissible via administrative appeal and, in part, through the constitutional complaint.
Motivazione estratta
A cantonal final decision on a special land-use plan can be reviewed under federal planning law where non-application of Art. 24 RPG is alleged. Pure cantonal law issues without close federal nexus belong only in constitutional review.
