Questione giuridica chiave
Whether the subsidiairy public-law appeal could challenge the original cantonal classification order directly.
Decisione estratta
The direct challenge to the original classification order was inadmissible because the cantonal appellate court had full review powers.
Motivazione estratta
The appeal normally lies only against final cantonal decisions; a direct challenge to the lower authority is exceptional only when the cantonal appeal court's review is narrower than that of the Federal Court, which was not the case here.
