Question juridique clé
Whether the cantonal court failed to examine the appellant's constitutional challenge to the declassification decision.
Solution extraite
Yes. The cantonal court omitted to decide the objections based on Articles 5 and 26 of the Constitution regarding the declassification itself.
Motifs extraits
Those grievances were expressly raised against the declassification and its incorporation into private domain, not only against the later building project. By not addressing them, the cantonal court committed a formal denial of justice and violated the duty to be heard.
