Second negligent actor jointly liable for degree of aggravation.
Another post-Restatement (Second) result.
Dependent causation
Dillon v. Twin State G. & E. Co. (NH 1932)
Two causal acts, one dependent on the other. But for negligence of first actor, plaintiff would not have been exposed to dangerous situation created by negligent second actor. Second negligent actor only responsible for additional portion of damages.
Deliberate criminal or tortious intervention
Effect on causal chain depends on foreseeability. Restatement (Second) § 448.
Foreseeable intervention does not negate proximate cause. Brower v. New York Central & H.R.R. (NJ 1918)
Unforeseeable intervention does negate proximate cause. Watson v. Kentucky & Indiana Bridge & Ry. Co. (KY 1910)
Probability of third-party tortious intervention can be the source of defendant’s negligence and proximate causation. Restatement (Second) § 449.
Keys left in car in violation of statute. The mischievous intervention of third parties was foreseeable and was the driving force behind the statute. Causal chain not severed.
Vesely v. Sager (CA 1971)
Injury to third party is foreseeable and proximate result of publican serving alcohol in violation of statute.
Gorris v. Scott (U.K. 1874)
Where injury is entirely outside class statute was designed to prevent, there is no breach of duty to this plaintiff with respect to this risk.
Multiple intervening actors
Pittsburg Reduction Co. v. Horton (AR 1908)
Apparently safe but actually dangerous object passed through many hands before causing injury. Defendant’s original negligence in disposal of object too diluted by subsequent intervening acts.
Cow injured by defendant recovers and knocks plaintiff over, causing serious injury. Defendant is liable.
In re Guardian Casualty Co. (NY 1938)
Defendant’s car hit stone wall due to negligence. Stone fell and injured plaintiff during subsequent removal of wreck from wall. Defendant is liable.
Coincidence
Berry v. The Borough of Sugar Notch (PA 1899)
Plaintiff’s own negligence or statutory violation is not proximate cause of injury where it had no effect on likelihood of injury.
Central of Georgia Ry. Co. v. Price (GA 1898)
Defendant’s negligence exposed plaintiff to unforeseeable, preexisting risk posed by defective lamp. No liability because of coincidence and great causal attenuation.
Consequences which flow in unbroken sequence, without intervening efficient cause, are natural and proximate and the original wrongdoer is responsible for them.
Palsgraf v. Long Island R.R. (NY 1928) Cardozo, C.J.
No liability where plaintiff is not in class of persons to which defendant owed duty.
Gorris/Sugar Notch reasoning.
Skirts the proximate cause issue entirely even though there is but-for cause an no intervention. Also skirts issue of who comprises protected class.
This is the majority rule regarding linking liability to duty to a protected class.
This is not the majority rule as a way to avoid proximate cause issues. (Dissent also objected, following Polemis.)
