Great Atlantic & Pacific Tea Co. v. Cottrell

Background

A Maryland grocery company that owns 38 stores in Mississippi operates a milk-processing plant in Kentwood, Louisiana. The company invested over $1 million in that plant and sought a Mississippi permit to sell Kentwood milk at its Mississippi outlets. Mississippi denied the permit because Louisiana had not signed the reciprocal agreement required by §11, even though inspections showed the Kentwood plant met Mississippi’s standards and received sanitation ratings above 90 percent. The company sued, and a three-judge District Court upheld Mississippi’s reciprocity rule.

Reasoning

The Court asked whether Mississippi could refuse out-of-state milk that met its health requirements solely because the originating State had not entered into a reciprocity agreement. Relying on prior cases such as Dean Milk, the Court explained that states may protect health but not use economic isolation to block interstate trade. The Court found the reciprocity clause did not actually ensure higher health standards and that less burdensome alternatives—inspection by Mississippi officials or reliance on interstate sanitation ratings—were available. Because the mandatory reciprocity requirement excluded wholesome Louisiana milk and placed a heavy burden on interstate commerce, it could not be justified.

Real world impact

The ruling means Mississippi cannot refuse milk that satisfies its health rules simply because another State refuses a reciprocity pact. Retailers, out-of-state producers, and consumers may gain clearer access to interstate milk shipments when health standards are met. The decision reverses the District Court and sends the case back for further proceedings consistent with this opinion.
