The case involved a [[Connecticut]] "[[Comstock law]]" that prohibited any person from using "any drug, medicinal article or instrument for the purpose of preventing conception." By a vote of 7–2, the Supreme Court invalidated the law on the grounds that it violated the "right to marital [[privacy]]", establishing the basis for the right to privacy with respect to intimate practices. This and other cases view the right to privacy as a right to "protect[ion] from governmental intrusion."

Although the [[United States Bill of Rights|Bill of Rights]] does not explicitly mention "privacy", Justice [[William O. Douglas]] wrote for the majority that the right was to be found in the "[[penumbra (law)|penumbras]]" and "emanations" of other constitutional protections, such as the [[self-incrimination clause]] of the [[Fifth Amendment to the United States Constitution|Fifth Amendment]]. Justice [[Arthur Goldberg]] wrote a concurring opinion in which he used the [[Ninth Amendment to the United States Constitution|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 to the United States Constitution|Fourteenth Amendment]].
