Whether obscenity is protected speech or press under the First Amendment, or under the Fourteenth Amendment as applied to the States.
Holding
No. Obscenity is not within the constitutionally protected area of speech or press.
Reasoning
The Court began with the purpose of the speech and press guarantees: securing the free exchange of ideas needed for political and social change. Ideas with even slight redeeming social importance—including unpopular and offensive ideas—receive constitutional protection unless they encroach on more important interests. But the Court concluded that obscenity, unlike the communication of ideas, was historically treated as wholly lacking redeeming social importance.
History supported that conclusion. At the founding, constitutional protections for expression coexisted with laws punishing libel, blasphemy, profanity, and obscene publications. The Court also pointed to the longstanding and widespread legislative judgment against obscenity in federal law, state law, and international agreements. In the Court's view, that history showed that the First Amendment's broad language was not understood to protect every utterance.
Because obscenity falls outside protected expression, the government need not prove that an obscene publication creates a clear and present danger of unlawful conduct. The Court analogized to libel: once a category of expression is outside First Amendment protection, the clear-and-present-danger inquiry does not govern its punishment.
