Constitutional Law - Federal Occupation of Field of Control of Subversives

Defendant was chairman of the Communist Party for the western district of Pennsylvania. He was charged with willfully advocating the violent overthrow of the United States Government, and his conviction under state statute was sustained by the superior court. On appeal, held, reversed. The federal Smith Act pre-empted the field of control of subversive activities and the state law is therefore void.
