Common questions
Frequently Asked
3
How does prudent foresight differ from simple foreseeability in tort causation?+
Prudent foresight asks what a reasonable person would have anticipated given ordinary judgment and available information. It supplies the standard for deciding whether an intervening cause or resulting harm remains within the original actor's scope of responsibility rather than becoming too remote.
Supporting sources
Does prudent foresight require proof that the exact sequence of events was imagined in advance?+
No. The test focuses on whether the general type of harm or the risk of intervention was within the range a reasonable person would have considered. Precise details of the accident need not have been foreseen.
Supporting sources
When does the absence of prudent foresight cut off liability for an original act?+
Liability ends when an independent force or highly unusual occurrence intervenes in a way that a reasonable person would not have anticipated. The original conduct is then treated as too attenuated from the final injury.
