Lesson 19: Defenses to Strict Liability

Strict liability is a legal doctrine that makes an individual or entity responsible for their actions or products, even without fault or negligence. However, there are certain defenses available that can mitigate or eliminate liability. Understanding these defenses is crucial for anyone navigating the complexities of torts law.

1. Assumption of Risk

One common defense to strict liability is the assumption of risk. This occurs when the plaintiff voluntarily and knowingly assumes the inherent risks associated with a particular activity or product.

Note: Assumption of risk requires that the plaintiff had actual knowledge of the risk and voluntarily accepted it.

2. Contributory and Comparative Negligence

Similar to defenses in negligence cases, contributory and comparative negligence can be used in strict liability cases. These defenses argue that the plaintiff's own negligence contributed to their harm.

Contributory Negligence: If the plaintiff is found to be even partially at fault, they may be barred from recovering any damages.
Comparative Negligence: The plaintiff's recovery is reduced by their percentage of fault.

3. Statutory Compliance

If the defendant can show that they complied with all relevant statutes and regulations, this can serve as a defense to strict liability. This is particularly relevant in product liability cases.

4. Misuse or Abnormal Use

If the plaintiff used a product in a way that was not intended or foreseeable, the defendant may be able to use misuse or abnormal use as a defense. This defense requires demonstrating that the misuse was the actual cause of the harm.

5. Act of God

An "Act of God" defense can be used if the harm was caused by natural forces that were unforeseeable and beyond human control, such as hurricanes, earthquakes, or floods.

Example: If a wild animal escapes from a zoo due to an unexpected earthquake, the zoo may use the Act of God defense to avoid strict liability.

Mathematical Representation of Comparative Negligence

In cases where comparative negligence is applied, the following formula can be used:

\[ \text{Recovery} = \text{Total Damages} \times (1 - \text{Plaintiff's Percentage of Fault}) \]
