Question juridique clé
Whether the public-law appeal was admissible and the neighbor had standing.
Solution extraite
The appeal was generally admissible, and standing under neighbor-protection rules was left undecided because the appeal failed on the merits.
Motifs extraits
The court noted that the neighbor invoked constitutional arbitrariness and cited planning provisions that can also protect neighbor interests, but it did not need to decide standing because the claim was meritless anyway.
