In United States tax law history, the Tariff of 1883, also known as the Mongrel Tariff Act by its critics, reduced high tariff rates only marginally, and left in place fairly strong protectionist barriers.
Nix v. Hedden
The law exempts fruit but not vegetables, causing tomato importers to file suit claiming that tomatoes are a fruit, resulting in the unanimous U.S. Supreme Court decision in Nix v. Hedden (May 10, 1893) that tomatoes are to be considered a vegetable for purposes of this tariff. ==References==
