Legal Cause in United States

Legal Cause 

Causation in tort is divided between factual cause, i.e. those necessary causes but for which the tort would not have occurred, and proximate or legal cause, which concerns those causes which were not only necessary but sufficient (or sometimes efficient) and thus which will give rise to legal liability in tort.
