Questione giuridica chiave
Whether private conservation organizations may directly challenge a cantonal structure plan revision by federal-law appeal.
Decisione estratta
No. Structure plans bind authorities, not private associations without spatial-planning decision-making powers; the appeal is therefore inadmissible.
Motivazione estratta
The court held that direct review of structure plans is reserved for authorities bound by them. Private entities are not directly subject to the plan, and any factual pre-effects do not create appealability. Their protection is ensured later through incidental review in the zoning-planning stage.
