Questão jurídica principal
Whether the factual findings that X. struck and knocked Y. down were arbitrary.
Decisão extraída
The factual assessment was not arbitrary; the witness evidence and surrounding circumstances supported that X. had displaced Y. and noticed or had to notice him.
Fundamentação extraída
The court found no relevant contradictions, no reason to doubt the cyclists' testimony, and no basis to infer the absence of contact from the lack of traces.
