Key legal question
Whether the cantonal non-reformatio in peius rule barred the appellate court from deviating from diminished culpability.
Extracted holding
The complaint did not show a substantiated arbitrary application of cantonal procedural law, so this point was not admissible.
Extracted reasoning
The Court reviewed cantonal law only for arbitrariness and held that the appellant merely invoked the provision without alleging or substantiating arbitrary application.
