Dennis V. United States - Aftermath

Aftermath

In 1957, the Court in Yates v. United States restricted the holding in Dennis, ruling that the Smith Act did not prohibit advocacy of forcible overthrow of the government as an abstract doctrine. While Yates did not overrule Dennis, it rendered the broad conspiracy provisions of the Smith Act unenforceable. Finally, in 1969, Brandenburg v. Ohio held that "mere advocacy" of violence was per se protected speech. Brandenburg was a de facto overruling of Dennis, defining the bar for constitutionally unprotected speech to be incitement to "imminent lawless action".
