The Supreme Court upheld the convictions of Communist Party members under the 1940 Smith Act, which led to more vigorous prosecution of alleged communists in the 1950’s.
Chief Justice Fred M. Vinson
Vinson significantly modified the clear and present danger test
Justices Hugo L. Black and William O. Douglas wrote strong dissents attacking the majority for seriously misreading the clear and present danger test and damaging freedom of speech in the United States. Because one of the activities for which the convictions were upheld was the defendants’ plan to publish a newspaper, these dissents also alleged that freedom of the press was endangered. Freed from the constraints of previous interpretations, the government began a vigorous prosecution of the Communist Party that continued until the Court’s decision in Yates v. United States
