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