Kernrechtsfrage
Whether the Geneva court breached the ban on reformatio in pejus by convicting for a different period and reducing the sentence.
Extrahierter Entscheid
No arbitrary application of cantonal procedure was shown; the appeal court changed the reasoning and period, but imposed a lighter sentence.
Extrahierte Begründung
The prohibition of reformatio in pejus concerns aggravation of the sanction, not every change in reasoning or legal characterization. Since the higher court did not increase the punishment, there was no unconstitutional arbitrariness.
