Facts of the Case

In what became known as the "Pentagon Papers Case," the Nixon Administration attempted to prevent the New York Times and Washington Post from publishing materials belonging to a classified Defense Department study regarding the history of United States activities in Vietnam. The President argued that prior restraint was necessary to protect national security. This case was decided together with United States v. Washington Post Co.

Question

Did the Nixon administration's efforts to prevent the publication of what it termed "classified information" violate the First Amendment?

Conclusion

Yes. In its per curiam opinion the Court held that the government did not overcome the "heavy presumption against" prior restraint of the press in this case. Justices Black and Douglas argued that the vague word "security" should not be used "to abrogate the fundamental law embodied in the First Amendment." Justice Brennan reasoned that since publication would not cause an inevitable, direct, and immediate event imperiling the safety of American forces, prior restraint was unjustified.
