Reading: Product Liability


Product liability is the area of law in which product manufacturers, distributors, and sellers are held responsible for the injuries caused by their products. Traditionally, product liability cases were decided according to the theory of negligence. Negligence is behavior that results in an unintentional injury or causes unintentional harm. Product liability law has evolved, however, and most states have extended product liability into the category of strict liability tort, too. Strict liability torts involve actions that are inherently dangerous and for which a party may be liable no matter how carefully he or she (or it) performs those actions. Regardless of whether the product liability claim is based upon negligence or strict liability, a product liability claim results from either a design defect, a manufacturing defect, or a failure to warn. To better appreciate the issues involved in cases of strict liability, let’s return to where we left you and your summer house-painting business at the beginning of this module.

Having escaped the house-painting business relatively unscathed, you head back home to rethink your options for gainful employment during your summer vacation. You’ve stored your only remaining capital assets—the two ladders and the platform that you’d used for scaffolding—in your father’s garage. One afternoon, your uncle notices them.

Examining one of the ladders, he asks you how much weight it’s designed to hold, and you tell him what the department manager at Ladders ’n’ Things told you: three hundred pounds per rung. Sensing that he might want to buy them, you hasten to add that, although you got them at a cut-rate price because of a little rust, they’re virtually brand-new. As it turns out, your uncle doesn’t want to buy the ladders, but he does offer to pay you $35 an hour to take them to his house and help him put up new roofing. He’s easygoing, he’s family, and he probably won’t sue you for anything, so you jump at the opportunity.

Everything goes smoothly until day two, when you’re working on the scaffolding two stories off the ground. In the process of unwrapping a bundle of shingles, one of the ladders buckles, and the entire platform comes down—landing you on your uncle’s stone patio with a cervical fracture.

Fortunately, there’s no damage to your spinal cord, but you’re in pain and you need surgery. Now it’s your turn to sue somebody. But whom? And for what?

Pursuing a Claim of Product Liability

Not surprising, your lawyer advises you to file an action for product liability—a claim of injury suffered because of a defective product (in your case, the ladder, of course). He goes on to say that in cases of product liability, there are three major bases for product liability claims. Section 2 of the Restatement (Third) of Torts: Products Liability identifies the following: manufacturing defect, design defect, failure to warn (also known as marketing defects). These are explained below:

  • Manufacturing defects are those that occur in the manufacturing process and usually involve poor-quality materials or shoddy workmanship.
  • Design defects occur where the product design is inherently dangerous or useless (and hence defective) no matter how carefully manufactured; this may be demonstrated either by showing that the product fails to satisfy ordinary consumer expectations as to what constitutes a safe product or that the risks of the product outweigh its benefits.
  • Failure-to-warn defects arise in products that carry inherent non-obvious dangers that could be mitigated through adequate warnings to the user, and these dangers are present regardless of how well the product is manufactured and designed for its intended purpose.

In most states, these defects are not legal claims in and of themselves, but they are the grounds for the action (negligence or strict liability). For example, a plaintiff might plead negligent failure to warn or strict liability for defective design.

Grounds of Strict Liability

For the sake of argument, let’s say that your lawyer isn’t very confident about pursuing a claim of negligence against the manufacturer of your ladder. The company doesn’t appear to have been careless in any of the three forms prescribed by law, and it will in any case be difficult to demonstrate the elements required in negligence cases. He suggests instead that you proceed on grounds of strict liability.

In tort law, strict liability is the imposition of liability on a party without a finding of fault (such as negligence or tortious intent). The claimant need only prove that the tort occurred and that the defendant was responsible. The law imputes strict liability to situations it considers to be inherently dangerous. It discourages reckless behavior and needless loss by forcing potential defendants to take every possible precaution. It also has the effect of simplifying and thereby expediting court decisions in these cases. In short, strict liability is based on the following legal theories:

  1. Certain products put people at risk of injury no matter how much care is taken to prevent injury.
  2. Consumers should have some means of seeking compensation if they’re injured while using these products.

A classic example of strict liability is the owner of a tiger rehabilitation center. No matter how strong the tiger cages are, if an animal escapes and causes damage and injury, the owner is held liable. Another example is a contractor hiring a demolition subcontractor that lacks proper insurance. If the subcontractor makes a mistake, the contractor is strictly liable for any damage that occurs.

In strict liability situations, although the plaintiff does not have to prove fault, the defendant can raise a defense of “absence of fault”: that is, the defense can argue that the defect was the result of the plaintiff’s actions—not of the productand that no inference of defect should be drawn solely because an accident occurs. On the other hand, if the plaintiff can prove that the defendant knew about the defect before the damages occurred, in some jurisdictions additional punitive damages can be awarded to the victim.

We’ll discuss damages at greater length in the next reading.
