Question juridique clé
Whether the public law appeal against the cantonal planning judgment was admissible under Art. 87 OG
Solution extraite
The challenged judgment was merely incidental and did not cause irreparable legal harm, so the appeal was not admissible at this stage.
Motifs extraits
The cantonal court did not finally deny building-zone status; it only rejected the specific placement in R2 and left open a later, more detailed planning solution. Any later definitive adverse decision could still be appealed. Mere prolongation of proceedings or increased costs is not irreparable harm.
