Kernrechtsfrage
Whether the neighboring landowners had standing to challenge the permit
Extrahierter Entscheid
Yes. Because they owned adjacent land and could obtain a practical benefit from preventing the project if the access defect were upheld, they were entitled to contest the permit.
Extrahierte Begründung
Under Art. 89 BGG and § 338a PBG/ZH, neighbors with spatial proximity and a practical interest may appeal all legal grounds that can affect their position. The alleged access deficiency was capable of preventing realization of the project, so the neighbors were sufficiently affected.
