Owen J. Roberts, Herndon v. Lowry — Opinion of the Court
“ The statute, as construed and applied, amounts merely to a dragnet which may enmesh any one who agitates for a change of government if a jury can be persuaded that he ought to have foreseen his words would have some effect in the future conduct of others. No reasonably ascertainable standard of guilt is prescribed. So vague and indeterminate are the boundaries thus set to the freedom of speech and assembly that the law necessarily violates the guarantees of liberty embodied in the Fourteenth Amendment. ”
