Question juridique clé
Whether the cantonal judgment violated Lausanne's municipal autonomy by requiring a neighborhood plan study under cantonal planning law.
Solution extraite
No. The cantonal court could review the municipality's refusal and, on the facts, order that a neighborhood plan study be initiated without unlawfully substituting itself for the municipal planning authority.
Motifs extraits
The Federal Court held that the challenge was reviewable under municipal autonomy. It found no arbitrariness in the cantonal court's application of Arts. 66 and 67 LATC: the request met the formal conditions, the municipality's planning objectives did not clearly preclude a special planning measure, and the preservation of the area's urban qualities justified requiring a study.
