Questione giuridica chiave
Whether the federal appeal could challenge only the cantonal judgment and, indirectly, the lower decisions
Decisione estratta
Only the cantonal supreme-court judgment was directly appealable; the lower decisions were deemed indirectly challenged but could not be separately annulled.
Motivazione estratta
Because of the devolutive effect, only the appellate judgment is subject to review, although the subordinate decisions are treated as substantively included.
