Questione giuridica chiave
Whether the administrative law appeal was admissible in a purely cantonal public-law dispute
Decisione estratta
No. The dispute was based purely on cantonal law; the administrative law appeal was therefore unavailable.
Motivazione estratta
The challenged claim was not governed directly by federal public law. Using federal private-law limitation rules as supplementary cantonal law did not convert the matter into a federal public-law dispute.
