Questione giuridica chiave
Whether the public-law appeal was admissible and the subsidiary constitutional complaint barred
Decisione estratta
The public-law appeal was admissible; the requested declaratory relief was redundant; the subsidiary constitutional complaint was inadmissible because the ordinary appeal was available.
Motivazione estratta
The decision was a final decision of a last cantonal instance in public law; the appellant was entitled to appeal. A declaratory request lacks independent significance when the annulment request already covers the sought result. Subsidiarity excludes the constitutional complaint.
