Questão jurídica principal
Whether the accident insurer had conducted an insufficient investigation requiring remand for an expert assessment.
Decisão extraída
Yes. The court held that the investigation was insufficient in this case and that the matter had to be remanded so the insurer could order an expert report at its own expense.
Fundamentação extraída
Unlike another case in which remand to the CNA for an expert assessment was denied because no deficient investigation could be criticized, the present file showed an inadequate fact-finding basis.
