Motifs extraits
As a denouncing neighbor, he still had to satisfy Art. 89 LTF. The contested order did not clearly prejudice him; on the contrary, annulling it would delay the conformity measures he sought. He did not explain why immediate filing of the exterior plan was necessary or what concrete harm would result from later review at the occupancy-permit stage.
