What Are The Defenses To Negligence Per Se in Torts?

Clear answer to: What Are The Defenses To Negligence Per Se in Torts? with key cases, examples, and exam tips for law students.

Short Answer

Defenses to negligence per se include compliance with the statute, a reasonable mistake of fact, and the plaintiff's own negligence. These defenses can negate the presumption of negligence established by the violation of a statute.

Detailed Answer

Negligence per se arises when a defendant violates a statute that is designed to protect a specific class of people from a particular harm, thus making the violation itself proof of negligence. However, several defenses can be employed against a claim of negligence per se. The most prominent is that the defendant may show they acted in compliance with the statute, which would negate the breach element of negligence per se. For instance, if a driver was found to be speeding but had a medical emergency requiring immediate action, such compliance with the law would defeat the negligence assertion.

Another defense is a reasonable mistake of fact. If a defendant incorrectly believes that their actions did not violate the law due to a reasonable misunderstanding, they may argue that this mistake negates liability. For instance, if a builder mistakenly believes a construction procedure aligns with safety codes, they may assert that their failure to comply was not due to negligence.

Lastly, a plaintiff's contributory negligence or comparative negligence can also serve as a defense. If the plaintiff's own negligent actions contributed to the harm suffered, this could reduce or bar recovery altogether, depending on the jurisdiction's rules regarding contributory or comparative negligence.

In some jurisdictions, statutes may specifically allow for exceptions or defenses that can further limit liability under negligence per se. It is essential to analyze local statutes to identify any potential defenses that may apply. Overall, understanding these defenses allows for a more comprehensive grasp of negligence claims and their legal implications.

Key Cases
  • 1Martin v. Herzog (1920) - Established the principle that a violation of a statute constitutes negligence per se.
  • 2Trujillo v. DeLeon (2011) - Discussed the reasonable mistake of fact defense in the context of negligence per se.
  • 3Loughren v. Gonzalez (2006) - Addressed the interaction between negligence per se and comparative negligence.
  • 4Gordon v. American Museum of Natural History (1993) - Considered compliance with statutes as a defense to negligence per se.
Practical Example

Imagine a scenario where a pedestrian is injured while crossing the street where a 'no pedestrians' rule is enforced. The driver claims the pedestrian was clearly violating the statute. If the pedestrian can prove they were attempting to cross safely but did not see the sign due to an obstruction, this may establish a reasonable mistake of fact defense that challenges the negligence per se claim.

Exam Relevance

Understanding defenses to negligence per se is critical for tort exam questions where the test may involve analyzing statutory compliance and evaluating the applicability of legal defenses. Students should be prepared to apply these concepts to fact patterns.
