Questione giuridica chiave
Whether the public-law appeal could be used to challenge alleged violations of federal criminal law and fact findings
Decisione estratta
Such complaints were inadmissible to the extent they were merely federal-law arguments or unsupported attacks on the facts; the public-law appeal is subsidiarily limited to constitutional grievances.
Motivazione estratta
Claims on fraud elements and on the factual relationship with the victim belonged to cassation review. Fact challenges needed a substantiated allegation of arbitrariness, which was absent.
