Smith Act Is Found Constitutional

1966

In Dennis v. United States, the U.S. Supreme Court upholds the convictions of 12 Communist Party leaders who were convicted under the Smith Act of 1940, formally known as the Alien Registration Act. The law makes it illegal to teach or advocate the overthrow or destruction of the U.S. government, or publish any materials or organize a group that endorses such action. The majority writes that the “existence of the conspiracy” creates “a clear and present danger.”
