Questão jurídica principal
Whether the abstract challenge to the cantonal norm was admissible and timely
Decisão extraída
The challenge was admissible only as far as Carla Soldati had standing; Tullio Foglia's standing was left open.
Fundamentação extraída
The norm could be directly reviewed under federal law, the filing was timely, and Soldati was at least virtually affected as owner of land in a quartier-plan area.
