Over 100,000 cases have been brought against Monsanto Corporation nationwide, claiming its Roundup™ weed-killer contains a carcinogenic active ingredient, namely, glyphosate. Hundreds of such cases are pending in Pennsylvania alone. But for over 30 years, the U.S. Environmental Protection Agency (“EPA”) has found evidence of glyphosate’s non-carcinogenicity for humans, and in 2015, the EPA determined “that glyphosate is not likely to be carcinogenic to humans.” EPA, “Glyphosate,” https://www.epa.gov/ingredients-used-pesticide-products/glyphosate.
This long-held conclusion regarding the non-carcinogenicity of glyphosate informed the EPA’s decision to approve a label for Roundup that omitted any cancer warning. By approving (and reapproving, over decades) Roundup’s label—pursuant to its authority under the Federal Insecticide, Fungicide, and Rodenticide Act, 7 U.S.C. § 136 et seq. (“FIFRA”)—the EPA effectively foreclosed litigants from asserting state-law product liability claims against Monsanto based on a purported duty to warn for failing to include a cancer warning on Roundup’s label. This is so because, as the U.S. Court of Appeals for the Third Circuit recently held in Schaffner v. Monsanto Corp., 113 F.4th 364 (3d Cir. 2024), FIFRA expressly preempts any such claims.
To many, Schaffner appeared to provide the last word on the subject. But some Pennsylvania state courts have declined to adhere to FIFRA-preemption in the wake of the decision. Last month, for example, the Philadelphia Court of Common Pleas concluded a trial—involving, in part, the same state-law failure-to-warn claim deemed preempted in Schaffner—resulting in a $78 million verdict for the plaintiffs. Melissen v. Monsanto Co., No. 210602578 (Phila. Cnty. C.C.P. Oct. 10, 2024). To borrow from Dickens, there appears to be a Tale of Two Courts within Pennsylvania—federal courts (where FIFRA-preemption applies), and state courts (where it does not)—resulting in, among other problems, discord, non-uniformity, confusion, and incentivization of forum-shopping. …
