Schoenhofer v. McClaskey, No. 16-3226 (10th Cir. 2017)
Annotate this CasePlaintiff Ralph Rogerson, a licensed pest-control applicator in Kansas, challenged a regulation of the Kansas Department of Agriculture on the ground that it required excessive pesticide treatment in preconstruction applications. He filed suit for declaratory and injunctive relief against the Secretary of the Department, claiming that the regulation: (1) was preempted by the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) because it conflicted with pesticide labels approved by the Environmental Protection Agency (EPA); and (2) was preempted by the Sherman Antitrust Act because it limited consumer choice and competition through retail price maintenance. The United States District Court for the District of Kansas rejected both claims, and Plaintiff appealed. The Tenth Circuit affirmed: the Kansas regulation was neither expressly nor impliedly preempted by FIFRA. And Plaintiff conceded the absence of an essential element of his Sherman Act claim.
