Torts: Strict Liability Explained | Law & Bar Exam Review

Two primary tests determine whether a product has a design defect: the risk utility test and the consumer expectation test. The risk utility test weighs whether the benefits of a product's design outweigh its risks. The consumer expectation test asks what a reasonable consumer would expect the product to do. For autonomous vehicles, the consumer expectation test is problematic because it's unclear what consumers would expect from exotic AI-controlled technology, making it difficult to apply consistently.

Products liability law rests on competing standards that fundamentally affect plaintiff recoveries. The consumer expectation test holds that consumers are entitled to expect products to be safe for their intended use—plaintiffs need only prove the product failed in an unexpected way. The risk utility test requires plaintiffs to prove not only injury but also that a safer alternative design existed and was feasible. The Supreme Court of Florida recently reaffirmed strict liability standards in the Auburn case, rejecting efforts to adopt risk utility tests that would have shifted burdens to plaintiffs. This decision preserved the consumer expectation test, which better serves injured parties seeking accountability from manufacturers who knew about dangers but continued selling dangerous products.

Products liability claims can be resolved through multiple tort theories. Strict liability imposes an absolute duty to make reasonably safe products, applying either the consumer expectation test (manufacturing defects) or risk-utility test (design/warning defects). Negligence requires duty specifically to the plaintiff, breach of reasonable care, and causation. Battery requires a voluntary act with intent to cause harmful touching, with intent shown through knowledge of substantial certainty rather than mere desire. Misrepresentation requires affirmative safety statements, reliance, and reasonable reliance. Each theory provides a pathway to liability depending on the facts presented.

This segment covers the two primary tests for determining design defects in products liability. The ALI (Restatement Third) test uses five factors: (1) usefulness of the product, where more useful products tolerate more risk; (2) functional utility, whether the dangerous nature is necessary for the product to function; (3) psychological utility, whether safety improvements justify making the product much uglier; (4) social cost, comparing injuries to the product's value; and (5) cost of redesign and increased product cost. The consumer expectation test asks whether the product was more dangerous than a reasonable consumer would expect. Both tests create triable issues of fact that prevent dismissal of the case.

In strict products liability cases involving defective products like hair dryers, the economic loss doctrine may limit recovery to contractual remedies. If a product only causes damage to itself (purely economic loss), you may be limited to your contractual remedies such as warranty claims. This affects statute of limitations—warranty periods may expire before you can file a tort claim. However, if the product causes damage to other property or personal injury, tort remedies become available.

Privity requirements determine who can sue whom. For negligence, the injured party must be a foreseeable plaintiff suing the actually negligent party. For strict liability, any foreseeable plaintiff can sue anyone in the commercial chain who put the defective product into commerce. For breach of warranty, UCC §2-318 provides options: (A) purchasers, family, household guests for personal injury; (B) anyone expected to be affected for personal injury; (C) anyone for personal injury and property damage. California allows any foreseeable plaintiff. The economic loss rule prevents recovery for pure economic losses without physical injury or property damage under negligence and strict liability.

The Economic Loss Doctrine limits tort claims when damage occurs only to a product, requiring resolution through contract or warranties. About 28 states fully enforce this doctrine, while 17 apply intermediate rules with exceptions. Key exceptions include: (1) Dangerous Defect Exception—damages are allowed when products cause foreseeable dangers or sudden losses; (2) Disappointed Expectations Exception—applies when damages were not foreseeable; (3) Independent Duty Rule—permits tort claims for fraudulent misrepresentation about product specifications. These exceptions provide pathways for recovery when strict economic loss doctrine would otherwise bar claims.

The economic loss doctrine, developed by the Supreme Court in East River S.S. Corp. v. Transamerica Casualty Insurance Co., distinguishes between warranty law and tort law in products liability cases. The doctrine holds that when a plaintiff is in a contractual relationship with a manufacturer, they can recover contract damages including lost profits and all economic losses. However, when no contractual relationship exists, plaintiffs can only sue for damages resulting from physical injury to persons or property other than the product itself. The key distinction rests on whether the defective product caused damage to the product itself or to other property. Items added to a vessel after purchase by the owner are considered 'other property,' even if installed before delivery, because such items cannot be warranted by the manufacturer.

California's economic loss rule holds that economic losses are recoverable in contract alone rather than in tort. When a plaintiff seeks to bring a negligence claim only for economic harms unaccompanied by personal injury or physical damage to property, the economic loss rule bars the negligence claim. The primary exception to this rule is where the plaintiff and defendant have a special relationship.

The law imposes strict liability on certain defendants for injuries resulting from specific activities because of policy considerations. Even if a defendant exercised all conceivable care to prevent injury, they remain liable for any injury proximately resulting from certain kinds of activity. This approach shifts the burden of risk and compensation away from injured parties toward those who control dangerous activities.

In the Boomer case, a cement plant spewed pollution interfering with neighbors' rights to reasonable use and enjoyment of property. The court adopted damages as a matter of right instead of injunction, showing the activity should be altered but not stopped. Strict liability addresses harms that will persist even after all reasonable precautions have been taken, where we don't demand more precaution. One explanation for differentiating domains of strict liability from negligence liability is that residual risks of normal activities are distributed reasonably justly because they fall randomly on the same population. Enterprise liability applies when the actor who inflicts harm can distribute the cost of the harm across the enterprise. Harm-based strict liability is conditional liability: you are only permitted to conduct certain kinds of activities if you take all reasonable precautions and then compensate victims for harm done. The wrong is exploiting victims by sacrificing them to beneficiaries of the activity, which is unjust.

Supporters of strict liability argue that it serves important policy objectives: (1) Deterrence - by removing knowledge defenses, strict liability encourages individuals to investigate and learn about relevant circumstances, thereby promoting socially desirable behavior; (2) Regulatory Efficiency - in complex regulatory environments, proving subjective knowledge is often impractical or impossible, making strict liability a more efficient mechanism for enforcing compliance; (3) Legislative Skepticism - legislatures may doubt the credibility of claims of ignorance in certain contexts, particularly when public welfare is at stake.

Enterprise liability theory justifies strict product liability by arguing that manufacturers and sellers are typically enterprises capable of spreading losses across many consumers. This makes injury costs manageable for both victims and defendants. However, 3D printing threatens this foundation by allowing anyone to manufacture complex goods without being an enterprise, potentially undermining the theoretical basis for strict liability.

Policy considerations related to the tortfeasor include: (1) Cheapest Cost Avoider - liability falls on the party who can prevent harm most easily and at lowest cost, exemplified by beverage companies adding extra twists to bottle caps to prevent caps from flying off; (2) Loss Spreading - liability falls on parties who can distribute harm costs across many people, like large companies adding small amounts to each product; (3) Deep Pocket Principle - liability falls on those with financial resources to pay damages; (4) Deterrence of Professionals - courts may limit duty of care to prevent professionals from becoming defensive and providing limited services. These considerations help courts determine whether to expand or limit liability based on the tortfeasor's characteristics and capabilities.
