Directions for Use
To make a prima facie case, the plaintiff has the initial burden of producing
evidence that he or she was injured while the product was being used in an
intended or reasonably foreseeable manner. If this prima facie burden is met, the
burden of proof shifts to the defendant to prove that the plaintiff’s injury resulted
from a misuse of the product. (See Perez v. VAS S.p.A. (2010) 188 Cal.App.4th
658, 678 [115 Cal.Rptr.3d 590] [risk-benefit design defect case]; Cronin v. J.B.E.
Olson Corp. (1972) 8 Cal.3d 121, 125–126 [104 Cal.Rptr. 433, 501 P.2d 1153]
[product misuse asserted as a defense to manufacturing defect]; see also CACI No.
1245, Affırmative Defense—Product Misuse or Modification.) Product misuse is a
complete defense to strict products liability if the defendant proves that an
unforeseeable abuse or alteration of the product after it left the manufacturer’s
hands was the sole cause of the plaintiff’s injury. (Campbell v. Southern Pacific Co.
(1978) 22 Cal.3d 51, 56 [148 Cal.Rptr. 596, 583 P.2d 121]; see CACI No. 1245.)
Misuse or modification that was a substantial factor in, but not the sole cause of,
plaintiff’s harm may also be considered in determining the comparative fault of the
plaintiff or of third persons. See CACI No. 1207A, Strict Liability—Comparative
Fault of Plaintiff, and CACI No. 1207B, Strict Liability—Comparative Fault of
Third Person.
Sources and Authority
• “[T]he term defect as utilized in the strict liability context is neither self-
defining nor susceptible to a single definition applicable in all contexts.”
(Johnson v. United States Steel Corp. (2015) 240 Cal.App.4th 22, 31 [192
Cal.Rptr.3d 158].)
• “A manufacturing defect occurs when an item is manufactured in a substandard
condition.” (Gonzalez v. Autoliv ASP, Inc. (2007) 154 Cal.App.4th 780, 792 [64
Cal.Rptr.3d 908].)
• “A product has a manufacturing defect if it differs from the manufacturer’s
intended result or from other ostensibly identical units of the same product line.
In other words, a product has a manufacturing defect if the product as
manufactured does not conform to the manufacturer’s design.” (Garrett v.
Howmedica Osteonics Corp. (2013) 214 Cal.App.4th 173, 190 [153 Cal.Rptr.3d
• “ ‘Regardless of the theory which liability is predicated upon . . . it is obvious
that to hold a producer, manufacturer, or seller liable for injury caused by a
particular product, there must first be proof that the defendant produced,
manufactured, sold, or was in some way responsible for the product . . . .’ ”
(Garcia v. Joseph Vince Co. (1978) 84 Cal.App.3d 868, 874 [148 Cal.Rptr.
843], internal citation omitted.)
• “[W]here a plaintiff alleges a product is defective, proof that the product has
malfunctioned is essential to establish liability for an injury caused by the
defect.” (Khan v. Shiley Inc. (1990) 217 Cal.App.3d 848, 855 [266 Cal.Rptr.
106], original italics.)
• “We think that a requirement that a plaintiff also prove that the defect made the
product ‘unreasonably dangerous’ places upon him a significantly increased
burden and represents a step backward in the area pioneered by this court.”
(Cronin, supra, 8 Cal.3d at pp. 134–135.)
• “[T]he policy underlying the doctrine of strict liability compels the conclusion
that recovery should not be limited to cases involving latent defects.” (Luque v.
McLean (1972) 8 Cal.3d 136, 145 [104 Cal.Rptr. 443, 501 P.2d 1163].)
• “A manufacturer is liable only when a defect in its product was a legal cause of
injury. A tort is a legal cause of injury only when it is a substantial factor in
producing the injury.” (Soule v. General Motors Corp. (1994) 8 Cal.4th 548,
572 [34 Cal.Rptr.2d 607, 882 P.2d 298], internal citations omitted.)
• “[S]trict liability should not be imposed upon a manufacturer when injury
results from a use of its product that is not reasonably foreseeable.” (Cronin,
supra, 8 Cal.3d at p. 126.)
