Legal analysis of Martin v. Herzog
Martin v. Herzog demonstrates the following principles of
tort law: 1. Violation of a statute is
negligence per se. 2. Under the doctrine of
contributory negligence, the plaintiff's negligence is a complete defense. If the plaintiff's negligence was a cause of the injury, the plaintiff is barred from recovery. In an opinion written by
Benjamin N. Cardozo, the
New York Court of Appeals affirmed the Appellate Division's ruling that the trial judge's jury instruction was erroneous. The trial judge had instructed the jury to consider the plaintiff's statutory violation when determining whether the plaintiff was contributorily negligent. The Court of Appeals held that the question of contributory negligence should not have been submitted to the jury. The plaintiff's violation of the statute was not mere evidence of negligence to be considered by the fact-finder; it
was negligence as a matter of law. The statute requiring highway travelers to have headlights codified the common law duty of one highway traveler to another. In failing to have headlights on his buggy, the plaintiff's
intestate breached a duty of care to other highway travelers. (Cf.
Tedla v. Ellman, where the plaintiffs' violation of a statute was not negligent because, in their particular situation, violating the statute was safer than adhering to it.) If a plaintiff's negligence
per se is to be contributory negligence, it must be a cause of the injury. In
Martin v. Herzog, the Court of Appeals found the plaintiff's traveling without lights an hour after sundown to be
prima facie sufficient evidence of negligence contributing to the accident. ==Causation issues==
