are Dusky v. United States and New York Times Co. v. Sullivan both landmark United States Supreme Court cases?
New York Times Co. v. Sullivan New York Times Co. v. Sullivan, 376 U.S. 254 (1964), was a landmark United States Supreme Court case that established the actual malice standard, which has to be met before press reports about public officials can be considered to be defamation and libel; and hence allowed free reporting of the civil rights campaigns in the southern United States. It is one of the key decisions supporting the freedom of the press. The actual malice standard requires that the plaintiff in a defamation or libel case, if he is a public figure, prove that the publisher of the statement in question knew that the statement was false or acted in reckless disregard of its truth or falsity. Because of the extremely high burden of proof on the plaintiff, and the difficulty of proving the defendant's knowledge and intentions, such claims by public figures rarely prevail.
Mancusi v. DeForte Mancusi v. DeForte, 392 U.S. 364 , is a 1968 decision of the United States Supreme Court on privacy and the Fourth Amendment. It originated in the lower courts as United States ex rel. Frank DeForte, appellant v. Vincent R. Mancusi, Warden of Attica Prison, Attica, New York, appellee, a petition for a writ of "habeas corpus" by a prisoner who had exhausted all his state appeals. By a 6–3 margin the Court affirmed the United States Court of Appeals for the Second Circuit's reversal of a district court denial of the petition.
