Many court cases brought by users of paraquat herbicides who have been diagnosed with Parkinson disease will be coordinated by U.S. federal Judge Nancy Rosenstengel of the Southern District of Illinois. On June 7, 2021 the US Judicial Panel on Multidistrict Litigation finds that centralization of these actions in the Southern District of Illinois will serve the convenience of the parties and witnesses and promote the just and efficient conduct of the litigation. The number of cases under this MDL has risen from 77 at the time of the decision to 157 cases in June 22, 2021 to 982 on April 19, 2022 and 1.050 on May 16, 2022. On Feb. 14, 2022 Judge Rosenstengel denied Syngenta and Chevron’s motions to dismiss claims for strict product liability, negligence, breach of implied warranty and violation of several states’ consumer protection laws but expressed that the plaintiffs’ public nuisance count was a “simple repackaging” of their product liability claims. The decision means that hundreds of agricultural workers and others who say they developed Parkinson’s disease as a result of occupational exposure to the herbicide paraquat can proceed with most of their claims against Syngenta Corp. and Chevron USA. A bellwether trial is expected in November 2022. A group of six cases for the initial Paraquat Parkinson’s disease bellwether trials have been identified on May 4, 2022. These cases are moving toward the first trial in November 2022. The plan is to take 16 sample Paraquat lawsuits out of the Parkinson’s disease lawsuits that have been filed.
