Question juridique clé
Whether the federal appeal against the cantonal refusal of suspensive effect was admissible.
Solution extraite
The appeal was in principle admissible as a public-law matter, but only to the extent constitutional complaints could be raised against the interim measure.
Motifs extraits
The challenged decision was an incidental ruling by the last cantonal instance in an building-law matter; however, in interim-measure proceedings the review is limited to constitutional rights.
