432 U.S. 333 (1977)
Hunt v. Washington State Apple Advertising Commission is a landmark case examining the constitutional limits placed on state regulations that impact interstate commerce.
Does the North Carolina statute requiring only the U.S. grade on apples shipped into the state violate the Commerce Clause by discriminating against interstate commerce?
A state law is invalid under the Commerce Clause if it discriminates against interstate commerce or places an undue burden on it, unless the state can show that it serves a legitimate local interest that cannot be adequately served by other non-discriminatory means.
The Supreme Court held that the North Carolina statute was unconstitutional because it imposed an undue burden on interstate commerce and was discriminatory in nature.
The decision in Hunt v. Washington State Apple Advertising Commission is pivotal for law students as it provides a clear framework for analyzing instances of state-level economic regulation that may impinge on interstate commerce. It strengthens the understanding of the Commerce Clause's role in maintaining open national markets and discourages parochial legislation that prioritizes local interests at the expense of national economic unity.
