Questione giuridica chiave
Whether the federal nullity appeal was admissible against the cantonal cassation ruling
Decisione estratta
Yes. The cantonal court definitively resolved a federal-law question on sentence severity, so the appeal was admissible.
Motivazione estratta
A nullity appeal is available against an interlocutory or preliminary decision when a cantonal last-instance authority has finally decided a determinative federal-law point that it cannot revisit.
