Key legal question
Whether the complaint based on the presumption of innocence and arbitrariness in fact-finding was admissible and well-founded.
Extracted holding
The challenge was inadmissible because it did not show, in a precise way, why the cantonal court's findings were arbitrary.
Extracted reasoning
The appellant merely preferred his own version of events to that of the injured party and failed to meet the strict substantiation requirement for arbitrariness.
