Question juridique clé
Whether the Federal Supreme Court could hear the appeal against the cantonal remand decision on costs and party compensation.
Solution extraite
The appeal was inadmissible because the remand decision was an interim decision and no irreparable harm or other exception under Art. 93 BGG was shown.
Motifs extraits
A decision remanding the matter for a new ordinary building-permit procedure does not end the proceedings. Even if only costs and compensation are contested, interim decisions are appealable only under the narrow conditions of Art. 93 para. 1 BGG, which were neither alleged nor apparent.
