Question juridique clé
Whether the cantonal court violated the appellant's right to be heard by relying on a 1995 study without prior submission.
Solution extraite
No violation occurred because the study was not decisive; the cantonal court relied mainly on on-site observations, and the appellant had long known of the document.
Motifs extraits
The right to be heard covers access to decisive evidence, but this document only corroborated the court's own findings and did not determine the outcome.
