Kernrechtsfrage
Whether the neighboring owner had standing to challenge the forest-setback issue and the planned project
Extrahierter Entscheid
Yes. As an immediate neighbor, the appellant had a sufficient practical interest and could also complain of a denial of justice on the forest-setback objection.
Extrahierte Begründung
Under Art. 89 Abs. 1 BGG and the unity of procedure, a directly affected neighboring owner may invoke violations that can affect the permitted use of the adjacent parcel and may raise formal denial-of-justice claims.
