Whether the complaint against the cantonal legislative amendment was admissible
Extrahierter Entscheid
The complaint was admissible as an abstract constitutional challenge against a cantonal enactment directly affecting the complainants' protected interests.
Extrahierte Begründung
The challenged rule concerned a cantonal ordinance with no other effective remedy; owners of land outside the building zone had a sufficient present or virtual legal interest.
