Key legal question
Admissibility of the constitutional appeal and scope of review
Extracted holding
The appeal was admissible in principle, but only insofar as it sought annulment of the cantonal judgment; the Federal Court reviewed the cantonal interpretation of planning law only for arbitrariness.
Extracted reasoning
The challenged judgment was a final cantonal decision; the appellant was directly affected. Because the remedy was cassatory, requests beyond annulment were inadmissible. The interference was not serious enough to justify broader review.
