Prior restraint is government censorship that blocks speech or publication before it happens. The government may punish harmful speech after the fact through libel suits or criminal charges, but it almost never gets to stop someone from speaking in the first place.
The Supreme Court first struck down this practice in Near v. Minnesota (1931), when Minnesota tried to shut down a newspaper under a law allowing courts to silence "malicious" or "defamatory" publications. In 1971, when President Nixon sought to block the New York Times and Washington Post from publishing the Pentagon Papers—classified documents revealing Vietnam War deception—the Court ruled 6-3 that the government failed to overcome the "heavy presumption against" prior restraint. The newspapers published the documents.
Courts have recognized only narrow exceptions: publishing troop movements in wartime, obscenity, and direct incitement to violence. This presumption against prior restraint remains one of the strongest protections in First Amendment law.
Prior restraint doctrine protects the public's right to know about government actions and decisions. It prevents officials from silencing criticism by claiming stories might be false or damaging, making accountability journalism possible.
People often think the government can stop publication if the information is false or classified. In practice, the government must prove an extraordinary need to block speech in advance, and this burden is almost never met.
