Question juridique clé
Whether the cantonal court violated the right to be heard by refusing further evidence, an on-site inspection, and an expert opinion.
Solution extraite
No. The court could, without arbitrariness, consider the file sufficiently clear and refuse the requested evidence.
Motifs extraits
Plans and photographs provided a sufficient view of the site; the proposed expertise was unspecified; the private agreement with another property owner was irrelevant to legality.
