Question juridique clé
Whether the public-law appeal was admissible against the cantonal judgment and whether the requested relief beyond annulment was permissible.
Solution extraite
The appeal was admissible only to the extent it attacked the incidental decision causing irreparable prejudice; requests for immediate zoning were inadmissible because the remedy is cassatory.
Motifs extraits
The judgment did not end the proceedings, but the postponement of buildability could irreparably prejudice the owner. However, public-law appeal is normally limited to annulment.
