Question juridique clé
Whether the appellant had standing to challenge the permit based on alleged arbitrary application of cantonal building law and property protection.
Solution extraite
Standing was not shown for the arbitrariness/property-rights complaint because the appellant relied on general traffic-safety interests rather than a direct, protected interest.
Motifs extraits
A neighboring owner may contest a building permit only if the invoked rules also protect neighbors and the affected owner is within their scope. The complaint did not establish this, and the alleged traffic effects on the appellant's own access were not specifically asserted.
