Kernrechtsfrage
Whether the appellants had standing to challenge the cantonal judgment despite not participating below
Extrahierter Entscheid
Yes. They were directly affected as landowners and, because the cantonal judgment first harmed them by annulling the plan, they could appeal.
Extrahierte Begründung
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.
