Kernrechtsfrage
Whether the constitutional appeal was admissible alongside the public-law appeal
Extrahierter Entscheid
The constitutional appeal was inadmissible because the public-law appeal was available.
Extrahierte Begründung
A final cantonal public-law construction decision fell within Art. 82 ff. LTF and none of the exceptions applied; therefore subsidiary constitutional review was excluded under Art. 113 LTF.
