Generally, in order to maintain a successful strict liability tort lawsuit against the manufacturer of a product, a consumer must be able to meet three conditions. First, the consumer must be able to show that the product in question had an unreasonably dangerous defect that caused injury or harm to the consumer. This defect could have arisen during the design, manufacturing, and/or distribution process. Second, the consumer must be able to show that the injury or harm resulting from the product occurred when the consumer was using the product in the manner in which it was intended to be used. Third, the consumer must be able to show that the product was not substantially altered, in terms of the way that the product was designed to operate, from the condition that the product was in at the time it was sold. If a consumer is able to meet these three conditions, then it is likely that he or she will be able to mount a successful products liability claim against the manufacturer of a defective product that caused injury to the consumer.
