Which case clarified freedom of the press by ruling against prior restraint during wartime (Pentagon Papers era)?

• A. Near v Minnesota
• B. Branzburg v. Hayes
• C. New York Times Co. v. Sullivan
• D. New York Times Co. v. United States

Answer: (D)

The main idea is the protection of press freedom against government censorship through prior restraint, even in wartime. In the Pentagon Papers era, the Supreme Court made clear that prior restraints on publication are harshly scrutinized and typically disallowed. In New York Times Co. v. United States, the Court blocked government attempts to stop the publication of a classified Vietnam War study, ruling that the government had not carried the heavy burden needed to justify prior restraint. The decision establishes a strong presumption against prior restraint and requires clear evidence of immediate, irreparable harm to national security before such censorship can be allowed. Context: earlier cases began chipping away at prior restraints (and the general principle that a free press should not be muzzled), while other cases address defamation or journalist privilege rather than publication bans.
