Decisão extraída
The lifting effort was not an extraordinary external event and did not involve extraordinary force; therefore the back injury was not an accident.
Fundamentação extraída
The insured gave contradictory accounts. The first version, consistent with the employer, was preferred. Moving the drill did not require exceptional exertion.
