Concurring, Whitney v. California, 274 U.S. 357, 375 (1927), at 375. In this case, in which the Court upheld a California anti-Communist statute, Brandeis, writing in a concurrence joined by Justice Oliver Wendell Holmes, Jr., concurred in the judgment but not in the reasoning. Whitney was later overruled (with the later Court adopting Brandeis's reasoning) in Brandenburg v. Ohio, 395 U.S. 444 (1969).
