In the case of In re: Paraquat Products Liability Litigation, MDL No. 3004 (S.D. Ill. 2024), the United States District Court for the Southern District of Illinois addressed the admissibility of expert testimony in a multidistrict litigation (MDL) concerning allegations that exposure to the herbicide paraquat caused plaintiffs to develop Parkinson’s disease. The involvement of a Products Liability Expert Witness was central to the court’s analysis.
