Questione giuridica chiave
Whether the Geneva Court of Cassation arbitrarily exceeded the limits of its cantonal review power by supplementing the trial court's facts.
Decisione estratta
Yes. The cassation court impermissibly added facts not contained in the first-instance judgment and thereby went beyond its limited review role.
Motivazione estratta
Under Geneva procedure, the cassation court may review legal errors and only interfere with fact-finding if the lower court's assessment is arbitrary; it may not re-establish the facts or complete the record like an appellate court. The passages it inserted were new factual findings used to confirm the defendant's participation in the drug network.
