Regarding strict product liability in Illinois, the term “unreasonably dangerous” is crucial in determining whether a product’s manufacturer can be held accountable for injuries caused by their products. This blog delves into the legal intricacies of this term, offering insights for legal professionals and consumers.

The Legal Landscape: Consumer Expectation vs. Risk-Utility Test

In the landmark case of Lamkin v. Towner, the Illinois Supreme Court presented two pathways for plaintiffs to prove a product was “unreasonably dangerous”: the consumer expectation test and the risk-utility test. These tests offer different lenses to evaluate a product’s safety. The consumer expectation test assesses whether a product carries risks that exceed the average consumer’s expectations anticipated. In contrast, the risk-utility test weighs the risks and benefits of a product’s design.

Practical Implications for Jurors

The Illinois Pattern Jury Instructions highlight the practical application of the term “unreasonably dangerous” in courtrooms. By instructing jurors to consider this term instead of “defect” or “defective condition,” the courts aim to make the concept more relatable and easier to understand for non-legal professionals. This approach helps jurors focus on a product’s inherent dangers rather than getting bogged down by technical definitions. For more details, refer to the Illinois Pattern Jury Instructions-Civil: rule 400.00.

Why “Unreasonably Dangerous” Matters

Understanding the definition and implications of “unreasonably dangerous” is essential for legal practitioners and consumers. For attorneys, it provides a clear framework to argue product liability cases effectively. It offers consumers a benchmark to gauge the safety of products they use daily.

Conclusion

In Illinois, the “unreasonably dangerous” concept is pivotal in strict product liability cases. It bridges the gap between legal theory and practical application, ensuring jurors can make informed decisions based on a product’s expected safety. The judicial system employs this concept to safeguard consumers and ensure manufacturers are held liable for their products.
