Questione giuridica chiave
Whether the nullity appeal could challenge the conviction under cantonal law and factual findings
Decisione estratta
The appeal was inadmissible insofar as it attacked cantonal law, and factual findings could be corrected only for manifest inadvertence, which was not shown.
Motivazione estratta
Nullity appeal is limited to federal law; the court is bound by facts unless there is a manifest inadvertence, not merely an evidentiary dispute.
