Minerva Dairy, Inc. v. Harsdorf

Dist. Ct. did not err in granting defendants’ motion for summary judgment in plaintiff-out-of-state butter producer’s section 1983 action alleging that Wisc. statute’s requirement that all butter sold in state must contain stamped grade by individual licensed by state violated Due Process and Equal Protection Clauses, as well as dormant Commerce Clause. Said statute was rationally related to state’s legitimate interest in giving consumers relevant product information and to promote commerce. Moreover, statute did not violate dormant Commerce Clause because it applied to both in-state and out-of-state butter producers.
