Narrative Opinion Summary
In the case of 754 P.2d 1385 (1988), the Colorado Court of Appeals reversed a trial court decision in favor of Magna American Corporation in a product liability lawsuit brought by Gary W. Patterson. Patterson, injured while using a woodworking machine lacking a protective guard, claimed damages based on strict liability for a design defect and negligence. The jury had initially ruled in favor of the defendant, but the appellate court identified errors in jury instructions concerning misuse and a presumption of non-defectiveness. The court found the misuse instruction improper due to lack of evidence that Patterson deviated from the machine's intended use. Additionally, the presumption that the product was non-defective ten years post-sale was unsupported, as the machine was sold prior to the relevant period. The appellate court clarified that the presumption should consider the first sale of a product line's design, not the specific machine. The decision was remanded for a new trial, with the plaintiff's other arguments not addressed due to procedural issues. This ruling emphasizes the importance of precise jury instructions in product liability cases involving strict liability and negligence claims.

Application: The court clarified that the relevant date for determining the presumption of non-defectiveness should be when the product line of a specific design was first sold to the public, not the sale of the individual machine.
Reasoning: The court disagrees with the plaintiff's interpretation of Colorado statute 13-21-403(3), asserting that the determinative date of sale should reflect when a product line of a specific design is first sold to the public, rather than the sale of the actual machine in question.

Application: The appellate court acknowledged that adjustments made by the plaintiff during operation could inform the negligence claim, even if not relevant to strict liability.
Reasoning: The defendant's argument regarding adjustments made during operation did not constitute misuse relevant to the strict liability claim, although it could inform the negligence claim.
