The litigation surrounding paraquat has evolved significantly in recent years. As of July 2024, over 5,770 paraquat lawsuits were pending, with the bulk of these cases consolidated into a multidistrict litigation (MDL) in the Southern District of Illinois under Judge Nancy Rosenstengel. The MDL process aims to streamline pretrial proceedings and manage the numerous cases more efficiently.
Recent court updates indicate that the first bellwether trial, originally scheduled for July 2023, has been postponed to 2024. Bellwether trials are critical in MDLs as they serve as test cases to gauge the reaction of juries to the evidence and arguments presented by both sides. These trials can influence the settlement negotiations for the remaining cases. The delay was attributed to the need for additional time to consider admissible evidence and expert witnesses.
In May 2024, the judge allowed plaintiffs an extension until June 10, 2024, to select 16 new potential bellwether cases for limited discovery. This extension was granted to ensure thorough preparation and examination of the cases before proceeding to trial. Additionally, in April 2024, Judge Rosenstengel dismissed four bellwether test trial lawsuits after rejecting the testimony of the plaintiff’s key expert on general causation. This ruling underscored the importance of robust scientific evidence in proving the link between paraquat exposure and Parkinson’s disease.
