Kernrechtsfrage
Whether the public law appeal could challenge the cantonal court's factual findings and proof assessment
Extrahierter Entscheid
The appeal could invoke constitutional and procedural defects and arbitrariness in fact-finding, but not the federal fraud element of astute deception, which belonged in cassation.
Extrahierte Begründung
The Federal Court distinguished between constitutional/arbitrariness review, admissible on public law appeal, and objections to the substantive federal criminal law elements, which were inadmissible in this procedure.
