Whether the Due Process Clause protects a fundamental right for homosexual adults to engage in consensual sodomy.
Holding
No. The Constitution does not recognize a fundamental right to engage in consensual homosexual sodomy.
Reasoning
The Court framed the claim narrowly: not as a general right of privacy or intimate association, but as a claimed fundamental right of homosexual persons to engage in sodomy. Under that framing, the privacy decisions involving marriage, procreation, contraception, abortion, child rearing, and family relationships did not establish the asserted right. The Court found no demonstrated connection between homosexual sodomy and the family, marriage, or procreation interests recognized in those cases.
The Court applied its substantive-due-process formulations for identifying fundamental liberties: rights that are implicit in the concept of ordered liberty or deeply rooted in the Nation’s history and tradition. It concluded that consensual homosexual sodomy met neither test because sodomy prohibitions had ancient roots, were offenses at common law, and were widely criminalized when the Bill of Rights and Fourteenth Amendment were ratified.
The Court also stressed institutional restraint. In its view, recognizing an unenumerated fundamental right requires caution because such a decision risks substituting judicial value judgments for the choices of state legislatures. The asserted right lacked sufficient grounding in constitutional text, structure, or historical tradition to overcome that caution.
