Key legal question
Whether the cantonal court violated the prohibition of reformatio in pejus by keeping the sentence unchanged after partial acquittal.
Extracted holding
No. Under Geneva procedure, the rule only bars aggravation of the sentence, and maintaining the first-instance sentence after a partial acquittal was not arbitrary.
Extracted reasoning
The appellate court did not increase the punishment; the prohibition protects against worsening the appellant's position, not against unchanged sentencing.
