Questione giuridica chiave
Whether the administrative-law appeal was available against the cantonal decision on the hazard map within the land-use plan adoption procedure.
Decisione estratta
No. The challenged decision rested exclusively on autonomous cantonal procedural law, and the federal rules on hazard maps were only framework provisions.
Motivazione estratta
Federal planning and forestry law did not regulate the procedure or legal effects of hazard maps; the cantons retained discretion. The case therefore did not concern a federal-law decision amenable to administrative-law appeal.
