Intervening cause

An intervening cause is an event that occurs after a tortfeasor's initial act of negligence and causes injury/harm to a victim. An intervening cause will generally absolve the tortfeasor of liability for the victim's injury only if the event is deemed a superseding cause. A superseding cause is an unforeseeable intervening cause. By contrast, a foreseeable intervening cause typically does not break the chain of causality, meaning that the tortfeasor is still responsible for the victim's injury -- unless the event leads to an unforeseeable result.
