Paraquat MDL Lone Pine Order Creates New Hurdles for Nonsettling Plaintiffs

Faegre Drinker on Products blog

The multidistrict litigation (MDL) concerning paraquat-based herbicides — In re: Paraquat Products Liability Litigation, MDL No. 3004 (S.D. Ill.) — has become a focal point in mass torts. Thousands of plaintiffs allege that exposure to paraquat caused them to develop Parkinson’s disease (PD). The litigation has featured high-stakes scientific disputes, key defense wins, a master settlement agreement, and now Case Management Order No. 25 (CMO 25, 2026 WL 1707147), a Lone Pine order with important implications for nonsettling plaintiffs and a potential roadmap for effective case management in other MDLs.
