Question juridique clé
Whether the public-law complaint was admissible against the cantonal decision approving construction derogations
Solution extraite
The complaint was admissible in principle under the applicable federal procedural rule, because the challenged cantonal decision formed part of the final decision and the opponents could directly contest it at federal level.
Motifs extraits
The court distinguished earlier case law on incidental decisions: here the commune had already issued the definitive building approval, so the cantonal decision on derogations and the communal decision together formed the final decision. The appellants therefore were not required to pursue cantonal remedies against the communal decision if they had no complaints against it.
