Question juridique clé
Whether the cantonal proceedings suffered from procedural defects requiring annulment of the building permits.
Solution extraite
The alleged defects did not justify annulment; the ordinary procedure was respected and the plan defects could be corrected without a new public display.
Motifs extraits
The communal and prefectural handling complied with the applicable cantonal building procedure, and the missing elements in the situation plan were not so serious as to require re-publication.
