Questione giuridica chiave
Whether the cantonal court arbitrarily assessed the evidence and violated the presumption of innocence / in dubio pro reo by finding the appellant authored the disputed signatures.
Decisione estratta
No serious and irreducible doubt had to arise on the record; the challenged findings were not arbitrary and the conviction stood.
Motivazione estratta
The Federal Court held that the appellant mainly repeated his own version of the facts. The expert report did not exclude authorship by the appellant and the similarity of certain letters, together with the modus operandi and motive accepted by the cantonal court, was sufficient. A mere alternative interpretation of the evidence could not replace the lower court's assessment.
