Lesson 25: Defenses in Product Liability Cases

Product liability involves holding manufacturers, distributors, suppliers, and retailers accountable for any injuries their products cause. However, there are several defenses that these parties can use to mitigate their liability.

1. Contributory and Comparative Negligence

Under the doctrine of contributory negligence, if the plaintiff is found to have contributed to their own injuries, they may be barred from recovering any damages. In comparative negligence, the plaintiff's recovery is reduced by their percentage of fault. Refer to our detailed Contributory Negligence and Comparative Negligence lessons for more information.

2. Assumption of Risk

If the plaintiff knowingly and voluntarily assumes a risk associated with a product, the defendant may use this as a defense. This means that the plaintiff was aware of the potential danger and chose to proceed anyway. Learn more in our Assumption of Risk section.

Note: Assumption of risk must be proven by the defendant and typically requires evidence that the plaintiff had actual knowledge and understanding of the risk.

3. Product Misuse

Another common defense is product misuse. If the product was used in a manner that was not intended or foreseeable by the manufacturer, the defendant might not be held liable. For example:

Using a hair dryer to dry clothes

4. State-of-the-Art Defense

The state-of-the-art defense argues that the product was manufactured in accordance with the current level of technological and scientific knowledge at the time of its production. This is often used in cases involving newer technologies.

Manufacturing cars without airbags in the 1960s

5. Statute of Limitations

A statute of limitations sets the maximum time after an event within which legal proceedings may be initiated. If the plaintiff fails to file a lawsuit within this period, the defendant can use this as a defense. Explore our Statute of Limitations section for more details.

6. Regulatory Compliance Defense

If the product complied with all applicable regulations and standards at the time of production, the defendant can argue that they should not be held liable. This defense highlights the importance of adhering to industry standards.

7. Preemption

Preemption occurs when federal law overrides state law. In product liability cases, if a federal regulation governs the product, it may preempt state laws and thus serve as a defense.

Important: Preemption can be complex and depends on the specific federal statute and the nature of the state law claim.
