"What led the Supreme Court in 1973 to legalize abortion during the first trimester of a pregnancy was the privacy doctrine articulated in Griswold v. Connecticut (1965) and its extension via the equal-protection clause in Eisenstadt v. Baird (1972). Griswold v. Connecticut (1965) was a birth control case in which contraceptive use was declared to be a privacy right inferred from various provisions of the Bill of Rights and the language of the Ninth Amendment, which reads: “the enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.” Neither privacy nor abortion is mentioned anywhere in the constitution or the Bill of Rights, so Justice Douglas in Griswold v. Connecticut (1965) resorted to finding “penumbras” and “emanations” from the First, Third, Fourth, Fifth, and Ninth Amendments. As he declared: [Prior] cases suggest that specific guarantees in the Bill of Rights have penumbras, formed by emanations form those guarantees that help give them life and substance. . . . 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.”"
