Manufacturers have an obligation to make their products safe for regular use. However, how far does this obligation extend? Are manufacturers required to make it overly difficult for consumers to modify their products? A recent Illinois Appellate Court decision examines to what extent manufacturers are liable for after-market modifications made to their products; Geronimo Perez v. Sunbelt Rentals, Inc., et al., Nos. 2-11-0382, 2-11-0486 cons (April 9, 2012).
In January 2008, Geronimo Perez was injured while using a scissor lift machine manufactured by JLG Industries. In his product liability lawsuit, Perez claimed that his injury could have been prevented if there had been a guardrail on the scissor lift machine. What is interesting about Perez is that JLG Industries had installed a guardrail when it designed its scissor lift; however, someone had removed the guardrail after the scissor lift machine left JLG’s factory.
So while JLG Industries had designed its scissor lift machine so that falls like Perez’s would be prevented, someone unconnected to the company had removed that safety feature. Yet Perez alleged that JLG was liable because it should have foreseen that someone would remove that guardrail, thereby causing his subsequent fall. JLG countered that it was not responsible for modifications others made to its product and that its scissor lift machine’s design was not defective.
