Kernrechtsfrage
Whether the appeal could be treated as a public-law constitutional complaint and whether appellants had standing.
Extrahierter Entscheid
The appeal was treated as a constitutional complaint to the extent it alleged procedural violations and infringement of property guarantees; standing existed for those claims, but not for attacking the regional plan designation or ZV 4.7.
Extrahierte Begründung
The challenged measure was a zoning revision not directly based on federal administrative law. The appellants, as tenants farming the land, could invoke property-related interests and procedural rights, but lacked a current and direct interest in challenging the internal delegation rule and had no standing against a merely binding regional plan.
