United States v. Colgate &amp; Co.United States v. Colgate &amp; Co. United States v. Colgate & Co. United States v. Colgate & Co., 250 U.S. 300 (1919), is a United States antitrust law case in which the United States Supreme Court noted that a company has the power to decide with whom to do business. Per the Colgate Doctrine, a company may unilaterally terminate business with any other company without triggering a violation of the antitrust laws. This case created an exception to vertical price restraints in vertical agreements. According to the ruling, resale price maintenance is generally illegal "per se", but if a supplier merely says it will not deal with resellers  that charge less than the supplier's stipulated price, the supplier need not deal with such a retailer. This is a narrow exception, as companies are still prohibited from threatening or warning price-cutters. Facts. Colgate & Co. had a policy of refusing to deal with vendors who sold below suggested retail price. Colgate simply refused to continue to deal with a vendor that Colgate determined was not abiding by the rules. In cutting off these contracts, Colgate was willing to allow a vendor to sell out current inventory. Judgment. The Sherman Act §§ 1-7, 15 note, is intended to prohibit  monopolies and combinations, which probably would interfere with the free exercise of their rights by those engaged, or who wish to engage in trade; but in the absence of any purpose to create or maintain a monopoly a manufacturer engaged in private business may exercise his discretion as to parties with whom he will deal, and may refuse to sell to those who will not maintain specified resale prices.
