Delaware v. Monsanto Company
Annotate this CaseAccording to allegations in the complaint, for over forty years, Monsanto was the only U.S. manufacturer of polychlorinated biphenyls (“PCBs”). The federal government and states spent enormous sums cleaning up PCB environmental contamination. The State of Delaware alleged Monsanto knew that the PCBs it produced and sold to industry and to consumers would eventually be released into the environment and would cause lasting damage to public health and the State’s lands and waters. The State brought this action to hold Monsanto responsible for its cleanup costs, asserting claims for public nuisance, trespass, and unjust enrichment. A Delaware superior court dismissed the complaint, reasoning that even though the State alleged Monsanto knew for decades PCBs that were toxic and would contaminate the environment for generations, the State: (1) could not assert a public nuisance claim or trespass claim because Monsanto manufactured PCB products, which entered the environment after sale to third parties; (2) State did not have standing to bring a trespass claim because it held public lands in trust rather than outright and therefore did not have the exclusive possession of land needed to assert a trespass claim; (3) the superior court held it lacked subject matter jurisdiction to hear the unjust enrichment claim as a standalone claim; and (4) the State could not use an unjust enrichment claim to recover future cleanup costs. The Delaware Supreme Court found the State pled sufficiently that even though Monsanto did not control the PCBs after sale it substantially participated in creating the public nuisance and causing the trespass by actively misleading the public and continuing to supply PCBs to industry and consumers knowing that PCBs were hazardous, would escape into the environment after sale to third parties, and would lead to widespread and lasting contamination of Delaware’s lands and waters. Further, the Supreme Court found the State alleged that it owned some land directly and therefore had exclusive possession of that land needed to assert a trespass claim. The Court affirmed in all other respects, and remanded the case for further proceedings.
