Key Takeaways

• Twenty states and the District of Columbia are challenging Monsanto’s claims regarding federal pesticide law preemption in a Supreme Court case.
• The court is reviewing a previous verdict awarded to a man who developed cancer after using Roundup, which he claims lacked adequate warning about its risks.
• Monsanto has proposed a $7.25 billion settlement for ongoing claims and asserts that state failure-to-warn claims should be preempted by federal law.

Overview of the Case

Twenty states, along with the District of Columbia, are opposing Monsanto (an indirect subsidiary of Bayer) in a pivotal Supreme Court case that centers on whether federal pesticide law supersedes state lawsuits alleging failure-to-warn. The case arises from a $1.25 million verdict awarded to a Missouri man, Duane Durnell, who claims that exposure to Roundup herbicide caused his non-Hodgkin lymphoma, and alleges that the product’s label failed to adequately warn about this risk.

Monsanto has called for the Supreme Court to uphold its position that the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) preempts such lawsuits. The company argues that FIFRA explicitly limits the states’ ability to impose additional warning requirements on federally approved pesticides. In response, an amicus brief filed in support of Durnell highlights that FIFRA allows states significant authority over pesticide regulation, including the power to ban these substances outright.

A group of states supporting Durnell argues that the regulation of harmful substances is historically a matter of state authority. Their brief states, “Preemption through strict federal agency action poses particular threats to state sovereignty.” The states steer clear of discussing the underlying health claims regarding glyphosate (the active ingredient in Roundup) while asserting that state laws should govern local decisions on pesticide use, rather than federal mandates.

Another brief, submitted by 15 states including Nebraska, supports Monsanto, highlighting that FIFRA should preempt state claims since they challenge the adequacy of federally approved pesticide labels. Further, they argue that states benefit from access to glyphosate products, and state regulations should not undermine this availability.

The debate also includes political aspects, as attempts in Congress to write the preemption into law have been met with resistance, particularly from Democrats who label the provision as a detrimental element to other legislation. The case, generating significant interest, is slated for oral arguments on April 27, with various briefs submitted both in favor of and against Monsanto.

Organizations such as the U.S. Chamber of Commerce and National Agricultural Aviation Association have also sided with Monsanto, while groups like Farmworker Justice and Public Citizen have filed in support of Durnell. This case reflects broader implications for state versus federal authority in regulating public health concerning pesticides, setting the stage for potentially significant legal and regulatory outcomes in the future.
