Although the Bill of Rights does not explicitly mention "privacy", Justice William O. Douglas wrote for the majority, "Would we allow the police to search the sacred precincts of marital bedrooms for telltale signs of the use of contraceptives? The very idea is repulsive to the notions of privacy surrounding the marriage relationship." Justice Arthur Goldberg wrote a concurring opinion in which he used the Ninth Amendment in support of the Supreme Court's ruling. Justice Byron White and Justice John Marshall Harlan II wrote concurring opinions in which they argued that privacy is protected by the due process clause of the Fourteenth Amendment.
