Question juridique clé
Whether the appellant had standing to challenge the building permit before the cantonal court
Solution extraite
The appellant was sufficiently affected by the planned construction, given the topography, sightlines, and proximity, and therefore had standing.
Motifs extraits
Cantonal authorities may not apply stricter standing requirements than Art. 89 BGG allows. Standing depends on concrete special impact, not on direct adjacency alone; the lower court relied too much on the absence of direct boundary contact and ignored the practical effects of the project on downhill neighboring parcels.
