Key legal question
Whether the cantonally established facts were arbitrary regarding A.'s conduct and the course of the altercation.
Extracted holding
The factual findings were not shown to be arbitrary; the complaint relied largely on an inadmissible own version of events.
Extracted reasoning
The challenged evidence did not show that A. intended or attempted to inflict bodily harm. The witness and the lower-court findings supported that A. only grabbed X., and the appellant failed to meet the strict substantiation requirements.
