Establishes immunity from liability for certain designers, manufacturers, sellers, and lessors of products

SB 1234 changes product liability law by requiring plaintiffs in injury lawsuits to prove a specific defendant made or sold the exact product that caused harm, not just a similar product. It grants immunity to manufacturers, sellers, designers, and lessors if they cannot be identified as the source of the specific product used by the injured party. The bill also protects entities whose designs were copied without authorization, shielding them from liability for injuries caused by the manufacturer's product. This law does not affect existing rules about mislabeling, fraud, or successor companies. It shifts the burden of proof to plaintiffs in personal injury or property damage cases involving products.
