Defense of Privacy

Traditionally, defenses to crimes were grounded in failure of proof or other specific provisions enumerated in the U.S. Constitution.

However, starting in 1965, the United States Supreme Court began to recognize certain rights that were not explicitly stated in the Constitution. One of these rights was the right to privacy, first recognized as having a Constitutional Basis in Griswold v. Connecticut

The court explained the doctrine:

The foregoing cases suggest that specific guarantees in the Bill of Rights have penumbras, formed by emanations from those guarantees that help give them life and substance. See Poe v. Ullman, 367 U.S. 497, 516-522 (dissenting opinion). Various guarantees create zones of privacy. The right of association contained in the penumbra of the First Amendment is one, as we have seen. The Third Amendment in its prohibition against the quartering of soldiers "in any house" in time of peace without the consent of the owner is another facet of that privacy. The Fourth Amendment explicitly affirms the "right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures." The Fifth Amendment in its Self-Incrimination Clause enables the citizen to create a zone of privacy which government may not force him to surrender to his detriment. The Ninth Amendment provides: "The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people." The Fourth and Fifth Amendments were described in Boyd v. United States, 116 U.S. 616, 630 , as protection against all governmental invasions "of the sanctity of a man's home and the privacies of life." * We recently referred [381 U.S. 479, 485] in Mapp v. Ohio, 367 U.S. 643, 656 , to the Fourth Amendment as creating a "right to privacy, no less important than any other right carefully and particularly reserved to the people." See Beaney, The Constitutional Right to Privacy, 1962 Sup. Ct. Rev. 212; Griswold, The Right to be Let Alone, 55 Nw. U. L. Rev. 216 (1960).
