Key legal question
Whether the neighbor had standing to raise the deficient-access objection against the building permit
Extracted holding
Yes. Because his parcel was immediately adjacent and a successful access challenge could prevent the project, he had a legally protected interest and could raise all relevant legal arguments.
Extracted reasoning
Standing under Art. 89(1) BGG depends on special factual proximity and practical benefit, not on whether the specific norm invoked directly protects the appellant. The cantonal authorities erred by applying a rüge-specific limitation to standing.
