A defective product in Georgia can be defective in one of three ways, and the category determines what the plaintiff must prove. Design defects question the entire product line. Manufacturing defects question a specific unit. Warning defects question the adequacy of instructions or warnings accompanying the product. Each category developed through Georgia case law, and each has its own evidentiary framework.
| Defect type | Question | Proof framework |
|---|---|---|
| Design | Is the entire product line defectively designed? | <em>Banks</em> risk-utility balancing test |
| Manufacturing | Did this individual unit deviate from the intended design? | Departure from specifications |
| Warning | Were the warnings or instructions inadequate? | Foreseeable-danger duty + warning adequacy |
Design defects ask whether the entire product line should never have been made this way #
A design defect exists when the product’s intended design is itself unreasonably dangerous, and a feasible safer alternative design existed at the time of manufacture. Every unit produced under that design carries the same defect. The plaintiff is not arguing that something went wrong in making this particular product. The plaintiff is arguing that the product as designed should not have been made.
Georgia uses the risk-utility balancing test from Banks v. ICI Americas, Inc., 264 Ga. 732, 450 S.E.2d 671 (1994), to determine design defect. The jury weighs the risks inherent in the design against the utility derived from the product, considering factors that include:
- The usefulness of the product
- The severity and likelihood of the danger
- The avoidability of the danger by the user
- The technology available at the time of manufacture
- The feasibility of an alternative safer design
- The cost and practicality of alternative designs
- The user’s knowledge of the danger
Plaintiffs typically present expert testimony on the feasibility of alternative designs that would have eliminated or reduced the risk while preserving the product’s utility.
Manufacturing defects ask whether this particular unit went wrong #
A manufacturing defect exists when an individual product departs from the manufacturer’s intended design due to error during production. Other units produced under the same design may be entirely safe. The defect is specific to the unit that caused the injury.
Proof of manufacturing defect typically involves:
- Comparison of the injuring product to the manufacturer’s specifications
- Comparison to other units from the same production run
- Identification of the specific production failure (incorrect assembly, inadequate quality control, substitution of materials)
- Expert analysis of how the defective unit differed from the standard
Manufacturing defect cases sometimes resolve relatively quickly when the defect is obvious (a missing component, a clearly incorrect assembly). Other times, manufacturing defects are hidden and require destructive testing of the product to identify.
Failure to warn defects ask whether the product told users what they needed to know #
A failure to warn (sometimes called a marketing or packaging defect) exists when the product lacks adequate warnings or instructions about foreseeable risks from its normal use. The product itself may be reasonably designed and properly manufactured, but it can still be defective because the user was not informed of dangers the manufacturer knew or should have known about.
Under Georgia law, as recognized in Thornton v. E.I. Du Pont De Nemours & Co., 22 F.3d 284, 289 (11th Cir. 1994), a manufacturer has a duty to give adequate warning of known or reasonably foreseeable dangers arising from the use of a product. This duty extends to all persons whom the manufacturer should reasonably foresee may use or be affected by the product.
A failure to warn can be proved by showing:
- Inadequate content (the warning did not address the actual risk)
- Inadequate visibility (the warning was too small, hidden, or poorly placed)
- Inadequate communication (the warning did not effectively reach the ultimate user)
- Inadequate post-sale warnings (the manufacturer failed to warn after discovering risks later)
Each defect type can produce distinct legal questions #
A single product may have more than one type of defect. A defective car, for example, could simultaneously involve a design defect (the design of a brake system creates excess risk), a manufacturing defect (this particular car was assembled incorrectly), and a failure to warn (the manual did not warn about the risk). Plaintiffs commonly plead multiple theories in product liability complaints.
The categories also produce different legal questions:
- Design defects raise the question of whether the manufacturer could have done better given the technology and economics of the time
- Manufacturing defects raise the question of whether quality control failed in this specific case
- Failure to warn defects raise the question of whether the manufacturer knew or should have known about the risk and whether the warnings provided were sufficient
These distinct questions affect the experts plaintiffs retain, the discovery they need, and the trial themes they develop.
Defenses vary substantially by defect type #
In design defect cases, manufacturers commonly argue that no feasible safer alternative existed, that the design served important utility, or that the user assumed an obvious risk. In manufacturing defect cases, manufacturers argue that quality control was reasonable or that the alleged defect did not actually cause the injury. In failure to warn cases, manufacturers commonly invoke the learned intermediary doctrine (in pharmaceutical or medical device cases), the sophisticated user defense (when the user was knowledgeable about the risk), or the open and obvious danger doctrine.
The defendant’s choice of defense depends largely on which category the plaintiff is pursuing.
