Key legal question
Whether the cantonal court violated in dubio pro reo / arbitrariness rules by finding the appellant participated in the robbery against A. SA.
Extracted holding
No. The DNA traces, similar modus operandi, and witness description formed a coherent body of evidence that could sustain the finding without arbitrariness.
Extracted reasoning
The Federal Court reviewed only arbitrariness in the evidentiary assessment. It held that none of the appellant's objections undermined the combined force of the indicia, so no serious and irreducible doubt remained.
