Work accident requires suddenness and health damage; injury alone does not define the accident concept.

The Supreme Court dismissed the plaintiff's cassation appeal regarding a work accident claim for a one-time compensation. The appellate court found that the plaintiff's back injury, occurring after lifting meat, lacked the required suddenness and did not constitute a permanent health damage linked to the event. The Supreme Court reversed this by clarifying that 'suddenness' refers to the immediate onset of external cause effects, not the delayed manifestation of symptoms, and that health damage is a statutory condition for benefits rather than a definitional element of the accident itself.
