Minnesota v. Barber 136 U.S. 313 (1890)
MINNESOTA v. BARBER 136 U.S. 313 (1890)
The Supreme Court unanimously held unconstitutional as a violation of the commerce clause a Minnesota statute that prohibited the sale for human consumption of meat slaughtered in another state and not inspected in Minnesota. The statute, the Court declared, forced citizens to buy only Minnesota meat, denying them the benefits of competition in interstate commerce.
