Swift and Co. v. United States

Date: January 30, 1905

Citation: 196 U.S. 375

Issues: Antitrust law; interstate commerce

Significance: Adopting the stream of commerce doctrine, the Supreme Court held that antitrust laws could be constitutionally applied to stockyard transactions.

The federal government charged several meatpackers, including Swift and Company, with fixing livestock prices at the stockyards, in violation of the Sherman Antitrust Act (1890). The companies argued that the buying and selling of livestock was an intrastate transaction, occurring while the cattle were “at rest.” For support, they pointed to United States v. E. C. Knight Co. (1895), which had narrowly defined the concept of interstate commerce.

Speaking for a unanimous Supreme Court, Justice Oliver Wendell Holmes held that the buying and selling of cattle was a part of a larger act of interstate commerce. Defining commerce as more of a practical than a technical, legal concept, Holmes ignored that the sales transactions took place in local jurisdictions. He wrote that these separate local transactions combined into “a current of commerce among the states.” At the time, the broad definition of commerce in the Swift decision was applied to very few economic activities because it did not overturn the Court’s earlier ruling that manufacturing was not a part of interstate commerce. The decision, however, helped lay a foundation for United States v. Darby Lumber Co. (1941).
