Stromberg v. California, 283 U.S. 359 (1931), was a landmark decision of the Supreme Court of the United States in which the Court held, 7–2, that a California statute banning red flags was unconstitutional because it violated the First and Fourteenth Amendments to the United States Constitution. In the case, Yetta Stromberg was convicted for displaying a red flag daily in the youth camp for children at which she worked, and was charged in accordance with California law. Chief Justice Charles Hughes wrote for the seven-justice majority that the California statute was unconstitutional, and therefore Stromberg's conviction could not stand.
