Week 5 - Failure to Warn: Foreseeability, Obvious Risks, and Industry Standards

Class Notes

402a

• Standard same, is it in a defective condition of unreasonably dangerous

• For all defects, must discuss SL and N

Third Restatement

• Similarly to RAD:

  • Foreseeable risks of harm

  • could have been reduced or avoided

  • by reasonable warnings from anyone

  • and omission renders product not reasonably safe

• Don’t need to write about SL and N, only in Manufacturing Defects

State of the art claim: Think only design
Treat negligence and SL as the Anderson standard

• N: requires playintiff to prove manufactuerer did not warn of risk for reasons which a reasonably prudent manufacturer should have known

• SL: defendant did not adequately warn of a particular risk that was known or knowable in light of the generally recognized and prevailing best scientific and medical knowledge

Instructions and warnings same thing
Looking at the alternative design

• There is no RAW in warning, plaintiffs want to resist talking about RAW

Distinction Between Instructions and Warnings

Instructions tell consumers what actions to take to stay safe, whereas warnings describe hidden dangers that are not obvious. Products may require both instructions and warnings, or just one depending on how obvious the risk or solution is.

Hidden Costs of Adding Product Warnings

Adding warnings is not completely free because printing manuals costs money and too many warnings can confuse or overwhelm users. Judges must weigh these practical and mental costs against the actual safety benefits when deciding if extra warnings are required.

The Legal Standard for Defective Warnings (Third Restatement 2c)

Under official legal standards, a product is defective if missing reasonable warnings makes it unsafe by failing to reduce predictable risks. Sellers and distributors are held liable if providing clear instructions could have easily prevented foreseeable harm to the customer.

Responsibilities of Commercial Sellers and Distributors

While manufacturers usually create warning labels, distributors down the supply chain must also ensure those safety warnings are adequate. Plaintiffs must prove in court that the provided instructions were unreasonable and failed to protect users from harm.

Warning Obligations for Wholesalers and Retailers Non-manufacturing sellers like wholesalers and retailers are held responsible when the original manufacturer fails to warn about risks. However, these sellers usually only need to issue their own extra warnings if they personally know about a specific hazard.

Duty Limits for Non-Sellers and Repairers All commercial sellers owe a basic duty to warn of hidden product dangers, but boundaries exist for non-seller service workers. Courts generally rule that repair workers do not have a legal duty to warn clients about dangerous defects unrelated to the specific job they were hired to fix.

Olson v Prosoco Background

Injury Caused by Mortar Cleaner David Olson was blinded in one eye when a container's cap popped off and splashed chemical cleaner into his face. He required extensive medical treatment and was eventually fitted with an artificial eye.

Issue at Hand

Prosoco's Appeal Argument Prosoco appealed the ruling, claiming that giving jury instructions on both strict liability and negligence was redundant. They argued that this overlap confused the jury and unfairly harmed their defense.

Olson's Defense of the Verdict Olson argued that presenting both legal theories to the jury was entirely appropriate for his case. He claimed that strict liability and negligence in this scenario relied on different types of legal proof.

Legal Standard

Illusory Distinction Between Theories The court concluded that separating strict liability and negligence in failure-to-warn cases is a false distinction in practice. Under both theories, plaintiffs must prove the seller knew or should have known about potential risks and failed to warn users.

Flaws in the Product-Versus-Conduct Distinction Separating strict liability and negligence based on product condition versus company conduct is not practically meaningful. In failure-to-warn cases, courts inevitably end up evaluating whether the manufacturer's behavior was reasonable.

Negligence as the Proper Standard Failure-to-warn claims must be submitted exclusively under a negligence theory rather than strict liability. Under this rule, manufacturers are held to an expert standard and evaluated on whether they failed to warn against scientifically knowable risks.

Impact of Independent Verdict Forms Although improper instructions usually require a new trial under general verdicts, the separate verdict forms in this case preserved the judgment. The error regarding strict liability did not negatively impact the jury's independent finding of negligence.

Different Jurisdictional Approaches to Failure-to-Warn Claims

Some state courts treat negligence and strict liability as separate claims in failure-to-warn lawsuits. To prevent jury confusion and conflicting verdicts, some states allow plaintiffs to argue both legal theories but present only one to the jury.

Unknowable Risk SL

Unknowable Risks and Toxic Chemicals Unknowable risks highlight the difference between strict liability and negligence, especially regarding toxic chemical products. Because dangerous chemicals cannot easily be redesigned, legal disputes focus almost entirely on whether companies warned consumers of hidden risks.

Anderson Asbestos Case Standard

In Anderson, the California Supreme Court ruled that asbestos failure-to-warn claims fall under strict liability rather than negligence. However, the court required plaintiffs to prove that the risk was known or reasonably knowable when the product was sold.

SL v. N

Reasonableness Versus Scientific Knowledge Strict liability differs from negligence because it does not examine whether a manufacturer acted reasonably or carefully. Instead, it only requires proving that the company failed to warn about risks known to the scientific community at the time.

Strict Liability's Strict Standard for Manufacturers Under negligence rules, a company might avoid liability if its own private testing reasonably suggested a warning was unnecessary. Under strict liability, however, a manufacturer is responsible if the scientific community as a whole knew about the risk.

Scientific Knowledge Standards in Lightfoot A court dismissed a cancer lawsuit against lumber suppliers because medical agencies did not officially recognize wood dust as carcinogenic during the exposure period. The court affirmed that manufacturers are only expected to know established scientific facts, not cutting-edge theories.

Extending Strict Liability to Prescription Drugs

The California Supreme Court applied strict liability rules to drug manufacturers who fail to warn doctors about known medication risks. The court rejected claims that this would slow medical progress, arguing that liability encourages companies to conduct thorough safety research.

Liability for Unknowable Risks in Beshada New Jersey courts allowed manufacturers to be held strictly liable for failing to warn about risks that were scientifically unknowable when sold. The court reasoned that profiting companies and society should bear the financial burden of injuries rather than innocent victims. Restricting Liability for Unknowable Drug Dangers The court refused to apply the rule of liability for unknowable risks to essential prescription drugs, limiting Beshada to its original facts. It noted that criticism from legal experts and public policy concerns justified protecting vital medications from this strict standard.

Shifting the Burden of Proof to Defendants

In strict liability warning cases, the manufacturer must prove that scientific information about a hazard was not reasonably obtainable. Because companies profit from their products and possess expert technical knowledge, courts place the responsibility on them to prove what was known.

Majority Standard Rejecting Unknowable Risk Liability

Most courts reject holding companies strictly liable for risks that were completely unknowable when a product was sold. Official legal standards support this majority position, though a small minority of state courts still hold manufacturers responsible using later discoveries.

Jamieson v. Woodward & Lothrop Background

Injury and Initial Lawsuit Mrs. Marguerite Jamieson suffered a severe eye injury when an elastic exerciser slipped during use, leading her to sue the manufacturer for negligence. The trial court granted summary judgment to the manufacturer, and Jamieson appealed the decision.

Plaintiff's Legal Claim The plaintiff argued that stretching the rubber band created a dangerous force that required safety features and clear warnings. She claimed the company was negligent for failing to warn customers that the band could slip off their feet.

Legal Standard

Limits on the Duty to Warn Manufacturers are not legally required to make products completely accident-proof or warn against every conceivable everyday hazard. Common items like knives, hammers, and pencils carry obvious risks for which sellers owe no legal duty to warn users.

Accident Versus Legal Liability The court ruled that the injury was an unfortunate accident rather than the result of any wrongdoing by the company. Under the law, proving an injury occurred is not enough to win a lawsuit without proof of actual negligence.

Obvious Properties of Rubber Bands The court noted that everyone knows stretched rubber bands snap back with force when released or slipped. Because this elasticity is common knowledge to adults and children alike, the company had no duty to warn about it.
