Questione giuridica chiave
Whether the public-law appeal was admissible insofar as it sought declaratory and monetary relief.
Decisione estratta
The appeal was only admissible as a request to annul the cantonal judgment; the declaratory and condemnation requests were inadmissible because the remedy is purely cassatory.
Motivazione estratta
A public-law appeal generally has only cassatory effect, so only an implicit request for annulment could be entertained.
