Wis. Stat. § 895.046 : PROVISIONS COMMON TO ACTIONS AND PROCEEDINGS IN ALL COURTS — DAMAGES, LIABILITY, AND MISCELLANEOUS PROVISIONS REGARDING ACTIONS IN COURTS — DAMAGES, RECOVERY, AND MISCELLANEOUS PROVISIONS REGARDING ACTIONS IN COURTS — Remedies against manufacturers, distributors, sellers, and promoters of products

(1g) LEGISLATIVE FINDINGS AND INTENT. The legislature finds that it is in the public interest to clarify product liability law, generally, and the application of the risk contribution theory of liability first announced by the Wisconsin Supreme Court in Collins v. Eli Lilly Company, 116 Wis. 2d 166 (1984), specifically, in order to return tort law to its historical, common law roots. This return both protects the rights of citizens to pursue legitimate and timely claims of injury resulting from defective products, and assures that businesses may conduct activities in this state without fear of being sued for indefinite claims of harm from products which businesses may never have manufactured, distributed, sold, or promoted, or which were made and sold decades ago. The legislature finds that the application of risk contribution to former white lead carbonate manufacturers in Thomas v. Mallett, 285 Wis. 2d 236 (2005), was an improperly expansive application of the risk contribution theory of liability announced in Collins, and that application raised substantial questions of deprivation of due process, equal protection, and right to jury trial under the federal and Wisconsin constitutions. The legislature finds that this section protects the right to a remedy found in article I, section 9, of the Wisconsin Constitution, by preserving the narrow and limited application of the risk contribution theory of liability announced in Collins.
(1r) DEFINITIONS. In this section:
(a) "Claimant" means a person seeking damages or other relief for injury or harm to a person or property caused by or arising from a product, or a person on whose behalf a claim for such damages or other relief is asserted.
(b) "Relevant production period" means the time period during which the specific product that allegedly caused a claimant's injury or harm was manufactured, distributed, sold, or promoted.
(2) APPLICABILITY. This section applies to all actions in law or equity, whenever filed or accrued, in which a claimant alleges that the manufacturer, distributor, seller, or promoter of a product is liable for an injury or harm to a person or property, including actions based on allegations that the design, manufacture, distribution, sale, or promotion of, or instructions or warnings about, a product caused or contributed to a personal injury or harm to a person or property, a private nuisance, or a public nuisance, and to all related or independent claims, including unjust enrichment, restitution, or indemnification.
(3) REMEDY WITH SPECIFIC PRODUCT IDENTIFICATION. Except as provided in sub. (4), the manufacturer, distributor, seller, or promoter of a product may be held liable in an action under sub. (2) only if the claimant proves, in addition to any other elements required to prove his or her claim, that the manufacturer, distributor, seller, or promoter of a product manufactured, distributed, sold, or promoted the specific product alleged to have caused the claimant's injury or harm.
(4) REMEDY WITHOUT SPECIFIC PRODUCT IDENTIFICATION. Subject to sub. (5), if a claimant cannot meet the burden of proof under sub. (3), the manufacturer, distributor, seller, or promoter of a product may be held liable for an action under sub. (2) only if all of the following apply:
(a) The claimant proves all of the following:
1. That no other lawful process exists for the claimant to seek any redress from any other person for the injury or harm.
2. That the claimant has suffered an injury or harm that can be caused only by a manufactured product chemically and physically identical to the specific product that allegedly caused the claimant's injury or harm.
3. That the manufacturer, distributor, seller, or promoter of a product manufactured, distributed, sold, or promoted a complete integrated product, in the form used by the claimant or to which the claimant was exposed, and that meets all of the following criteria:
a. Is chemically and physically identical to the specific product that allegedly caused the claimant's injury or harm.
b. Was manufactured, distributed, sold, or promoted in the geographic market where the injury or harm is alleged to have occurred during the time period in which the specific product that allegedly caused the claimant's injury or harm was manufactured, distributed, sold, or promoted.
c. Was distributed or sold without labeling or any distinctive characteristic that identified the manufacturer, distributor, seller, or promoter.
(b) The action names, as defendants, those manufacturers of a product who collectively manufactured at least 80 percent of all products sold in this state during the relevant production period by all manufacturers of the product in existence during the relevant production period that are chemically identical to the specific product that allegedly caused the claimant's injury or harm.
(5) LIMITATION ON LIABILITY. No manufacturer, distributor, seller, or promoter of a product is liable under sub. (4) if more than 25 years have passed between the date that the manufacturer, distributor, seller, or promoter of a product last manufactured, distributed, sold, or promoted the specific product chemically identical to the specific product that allegedly caused the claimant's injury and the date that the claimant's cause of action accrued.
(6) APPORTIONMENT OF LIABILITY. If more than one manufacturer, distributor, seller, or promoter of a product is found liable for the claimant's injury or harm under subs. (4) and (5), the court shall apportion liability among those manufacturers, distributors, sellers, and promoters, but that liability shall be several and not joint.
