Question juridique clé
Whether the public-law appeal was admissible against the cantonal judgment confirming the municipal order to file a retrospective building application and suspend works.
Solution extraite
The appeal was inadmissible because the challenged measure was an interlocutory decision that neither ended the dispute nor caused irreparable legal harm.
Motifs extraits
The order merely initiated a formal procedure to examine the substantive legality of the project; any refusal or grant of the building permit would come only later. Delay and extra cost are not irreparable legal harm under Art. 87 OG.
