Completx Litigation Center - If You Build It, They Will Come
Roundup Litigation
The Philadelphia Court of Common Pleas remains home to the largest single-plaintiff Roundup verdict in the nation after a jury awarded an astounding $2.25 billion in damages in January 2024. The award included $250 million in compensatory damages and $2 billion in punitive damages. The massive verdict was based on junk science that other courts had excluded and with a jury that reached this extraordinary outcome after only one hour of deliberation. Judge Susan Schulman later reduced the award to $404 million, and the decision was appealed in July 2024.
There are more than 400 Roundup cases alleging that exposure to glyphosate in the weedkiller caused plaintiffs to develop non-Hodgkin’s lymphoma pending in the Philadelphia Court of Common Pleas Complex Litigation Center, as trial lawyers look to capitalize on its plaintiff-friendly reputation.
In addition to the $404 million judgment, several other multi-million-dollar awards were upheld on appeal in 2025. These cases all were sparked by the now-infamous study from the International Agency for Research on Cancer, which has served as the foundation for the Roundup litigation. This 2015 report — in stark contrast to more than 800 scientific studies as well as analyses by the U.S. Environmental Protection Agency and Health Canada — concluded that glyphosate is “probably carcinogenic.” ATRF has written extensively about the problems surrounding the report, including the fact that an “invited specialist,” Christopher Portier, who had no prior experience working with glyphosate, advised the study while being paid by an anti-pesticide group and law firms suing over glyphosate.
Following Portier’s involvement, the final glyphosate study published by IARC was altered in at least 10 ways to either remove or reverse conclusions finding no evidence of carcinogenicity.
In one Philadelphia case that resulted in a $177 million verdict, which was upheld in May 2025, Monsanto was prevented from introducing studies proving that glyphosate is not a carcinogen but plaintiffs were allowed to rely on the controversial IARC study, which is “at odds with the extensive weight of scientific evidence worldwide.” The EU has re-approved the use of glyphosate for 10 years, following successful health and safety scientific assessments, and more courts outside of the U.S., including in Australia, have dismissed lawsuits with similar claims, finding that sound scientific evidence does not support a link between glyphosate and cancer.
Paraquat Litigation
Paraquat litigation, designated a mass tort in the Philadelphia Complex Litigation Center in 2021, involves claims that the widely used herbicide causes Parkinson’s disease. In March 2023, Judge Abbe Fletman approved a short-form complaint process, accelerating filings. As of November 18, 2025, over 1,550 Paraquat cases were pending in the CLC, with the first bellwether trial now scheduled for January 2026.
In July 2025, the Philadelphia CLC rejected Syngenta and Chevron’s motion to dismiss for forum non conveniens. The defendants argued that nearly 1,000 non-Pennsylvania plaintiffs could pursue their claims where they live, rather than in Philadelphia. Additionally, the defendants argued that Philadelphia jurors should not have to “bear the burden of jury duty” when these cases lack relevancy or connection to Pennsylvania or Pennsylvania law. Yet, the CLC ruled that “the attorneys benefit from the effectiveness and efficiency of Philadelphia’s Mass Tort Program,” which “clear[s] backlogs of cases not just in Philadelphia but throughout the country.”
Lawyer Reprimanded by Court for Interfering in Paraquat MDL Settlement Negotiations
Aimee Wagstaff, who resigned from the plaintiffs’ executive committee in the Paraquat multidistrict litigation, appeared before U.S. District Chief Judge Nancy Rosenstengel in Illinois to address allegations that she interfered with confidential settlement negotiations in the Paraquat MDL. Wagstaff is representing several clients in similar litigation in the Philadelphia Court of Common Pleas.
At issue was Wagstaff’s decision to email several plaintiffs’ lawyers on a list associated with an organization called Women En Masse. Judge Rosenstengel expressed concern that her actions appeared intended to “subvert the MDL settlement process.” Wagstaff maintained that she “never planned to sabotage a pending settlement” and was acting in the best interests of her clients pursuing separate cases in the Philadelphia Court of Common Pleas, which would be excluded from the federal settlement. Judge Rosenstengel, however, remained unconvinced, stating that Wagstaff seemed to be attempting to “undermine” and “blow up the settlement.”
The judge also questioned Wagstaff’s plans to discuss details of the confidential settlement and her decision to host a September 18 webinar attended by 263 plaintiffs’ lawyers. According to court transcripts, Khaldoun Baghdadi, co-lead counsel in the paraquat MDL, said there was “no way to interpret it apart from an effort to gain leverage in the Philadelphia proceedings.”
Hair Relaxer Litigation
In May 2025, the CLC designated litigation targeting hair relaxing products as a mass tort action, a move that is likely to attract plaintiffs’ lawyers from across the country who may prefer to avoid the similar, larger MDL established for federal cases. The litigation alleges that use of these products increases the risk of uterine cancer and can lead to other health problems. As of November 18, 2025, there were 26 cases pending in the CLC, but plaintiffs’ lawyers expect that number to increase according to their own websites. They also make it clear that they chose to bring their claims in the CLC based on its plaintiff-friendly reputation and handling of previous mass tort litigation.
Talcum Powder
This new mass tort designation, created alongside the hair relaxer designation, concerns Johnson & Johnson’s baby powder, or shower-to-shower powder, that is alleged to cause ovarian cancer. As of mid-November 2025, there were 177 suits that have been consolidated in Philadelphia, with the first two trial dates set for 2026. A recent KCIC report predicts a 25% increase in talc filings compared to 2024. Given Philadelphia is a preferred jurisdiction by plaintiffs’ lawyers for asbestos litigation, it most likely will see a surge in filings.
