Nix v. Hedden

[2] On March 3, 1883, President Chester A. Arthur signed the Tariff Act of 1883, requiring a tax to be paid on imported vegetables, but not fruit.

The John Nix & Co. company filed a suit against Edward L. Hedden, Collector of the Port of New York, to recover back duties paid under protest.

They argued against the tariff by pointing out that, botanically, a tomato is a fruit due to its seed-bearing structure growing from the flowering part of a plant.

They called two witnesses, who had been in the business of selling fruit and vegetables for 30 years, and asked them, after hearing these definitions, to say whether these words had "any special meaning in trade or commerce, different from those read".

The plaintiffs' counsel read in evidence from the same dictionaries the definitions of the word tomato, while the defendant's counsel then read in evidence from Webster's Dictionary the definitions of the words pea, eggplant, cucumber, squash, and pepper.

[5] Countering this, the plaintiff then read in evidence from Webster's and Worcester's dictionaries the definitions of potato, turnip, parsnip, cauliflower, cabbage, carrot and bean.

The court unanimously decided in favor of the respondent and found that the tomato should be classified under the customs regulations as a vegetable, based on the ways in which it is used, and the popular perception to this end.

Botanically, a tomato is a fruit. However, in common parlance it is a vegetable; hence the United States Supreme Court ruled that a tomato is a vegetable for the purposes of the customs regulations.
