Questão jurídica principal
Whether the neighbor had standing to challenge the accessibility/access-to-building issue for persons with disabilities.
Decisão extraída
The neighbor lacked a practical advantage from litigating that issue, so the cantonal court could declare this part of the appeal inadmissible.
Fundamentação extraída
Under the standing rules aligned with Art. 89 LTF and Art. 33(3)(a) LAT, a neighbor may appeal only if the outcome can improve his own situation. On the established facts, the alleged accessibility defect would at most require a stairlift, not prevent the building project, and the appellant did not show a concrete personal impact.
