John Carson v. Monsanto Company
92 F.4th 980
11th Cir.2024Background
- John D. Carson, Sr. used Monsanto’s herbicide Roundup for over thirty years and was later diagnosed with cancer, leading him to sue Monsanto for failing to warn about Roundup's carcinogenic risks.
- Carson’s lawsuit included several claims under Georgia law, but after a settlement and amendment to his complaint, only the failure-to-warn claim proceeded on appeal.
- Monsanto argued that the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) expressly and impliedly preempted Carson’s state-law failure-to-warn claim due to EPA's approval of Roundup's labeling.
- The district court sided with Monsanto and dismissed the failure-to-warn claim as preempted by federal law; Carson appealed.
- The Eleventh Circuit panel initially reversed, finding no preemption, but the en banc court vacated that decision and remanded for a clarified analysis of preemption.
- On remand, the Eleventh Circuit addressed both express and implied preemption arguments regarding FIFRA and found in favor of Carson.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Does FIFRA expressly preempt Carson’s state-law failure-to-warn claim? | Georgia failure-to-warn law imposes duties that parallel, not go beyond, FIFRA’s labeling requirements. | FIFRA preempts any state-law labeling requirements beyond EPA-approved labels; EPA approval precludes stricter state warnings. | FIFRA does not expressly preempt Carson’s failure-to-warn claim because Georgia law’s duty is parallel or less demanding than FIFRA. |
| Does FIFRA’s registration and EPA label approval create additional “requirements” with preemptive effect? | EPA's registration decision is not a binding, individualized "requirement"; it is only prima facie evidence of compliance, not conclusive or permanent. | EPA’s individualized label approvals qualify as "requirements" under FIFRA, thus preempting state-law claims about labeling. | EPA’s registration process does not create a “requirement” under FIFRA that preempts state-law failure-to-warn claims. |
| Do other EPA actions (letters, regulatory decisions) have preemptive effect on state failure-to-warn law? | EPA’s actions cited by Monsanto do not have the formality or legal force needed to preempt state law. | EPA letters and interim decisions show EPA would have rejected a cancer warning, so state law is preempted. | Agency actions lacked force of law and did not preempt Carson’s state-law claim. |
| Is Carson’s claim impliedly preempted (impossibility preemption) by federal law? | Monsanto cannot show that it was impossible to comply with both EPA and Georgia law; EPA never made a conclusive, binding rejection of a cancer warning. | EPA would not have approved a cancer warning, so Monsanto could not comply with both sets of laws. | No impossibility—Monsanto failed to show EPA would have rejected a warning; thus, state law is not impliedly preempted. |
