Questione giuridica chiave
Whether the appellants were entitled to challenge the modified Baulinien despite earlier, more onerous lines
Decisione estratta
Yes. They remained entitled to seek review because the formal prior lines were repealed and replaced, and owners may demand material review when planning rules affecting their land are revised or circumstances have changed.
Motivazione estratta
A formal new fixation was made, and Swiss case law allows owners to contest planning restrictions even if an earlier regime existed; changed factual and legal circumstances can justify re-examination.
