Question juridique clé
Whether the federal appeal was admissible when it challenged only the municipal demolition order and not the cantonal judgment.
Solution extraite
The appeal was inadmissible because the only permissible object of the federal appeal was the cantonal judgment, while the municipal order could not be attacked independently.
Motifs extraits
Under the devolutive effect, the municipal order was replaced by the cantonal judgment; the appellant did not formally seek annulment of that judgment, and the Federal Supreme Court may not go beyond the parties' conclusions.
