Nebbia v. New York

During the Great Depression, New York created a Milk Control Board with power to set minimum and maximum retail milk prices, aiming to protect struggling dairy farmers. Nebbia (defendant), a Rochester grocer, was convicted of selling milk below the fixed price. The county court affirmed his conviction, and Nebbia appealed to the U.S. Supreme Court, arguing the price-fixing scheme violated his due process right to freedom of contract.
