Questão jurídica principal
Whether the insured's death resulted from an accident, namely acetone intoxication, rather than a natural cause.
Decisão extraída
The court held, on the balance of probabilities, that the death was caused by acute acetone intoxication and therefore qualified as an accident.
Fundamentação extraída
The judicial experts' report was more convincing than the lower court's assessment. The evidence showed acetone was used on site, the toxicology results could be understated because of evaporation and sampling conditions, and no other detectable cause of death was established.
