Questione giuridica chiave
Whether the appellants had standing to challenge the cantonal judgment despite not participating below
Decisione estratta
Yes. They were directly affected as landowners and, because the cantonal judgment first harmed them by annulling the plan, they could appeal.
Motivazione estratta
They had a protected interest under Art. 89 LTF and were first affected by the appealed judgment, so no prior participation could be required as a bar to standing.
