Questione giuridica chiave
Whether the public-law appeal was admissible against the cantonal judgment.
Decisione estratta
The appeal was admissible in principle as a public-law matter, but only within the limits of the Federal Supreme Court Act.
Motivazione estratta
The dispute was not a public procurement case under cantonal law, so the exclusion for procurement matters did not apply. However, review of constitutional and arbitrariness claims remained subject to strict reasoning requirements.
