Key legal question
Whether the federal appeal against the cantonal refusal of suspensive effect was admissible.
Extracted holding
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.
Extracted reasoning
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.
