Bowers v. Hardwick, 478 U.S. 186 (1986), was a landmark decision of the US Supreme Court that upheld, in a 54 ruling, the constitutionality of a Georgia sodomy law criminalizing oral and anal sex in private between consenting adults, in this case with respect to homosexual sodomy, though the law did not differentiate between homosexual sodomy and heterosexual sodomy. This case was overturned in 2003 in Lawrence v. Texas, though the statute had already been struck down by the Supreme Court of Georgia in 1998.

The majority opinion, by Justice Byron White, reasoned that the Constitution did not confer "a fundamental right to engage in homosexual sodomy". A concurring opinion by Chief Justice Warren E. Burger cited the "ancient roots" of prohibitions against homosexual sex, quoting William Blackstone's description of homosexual sex as an "infamous crime against nature", worse than rape, and "a crime not fit to be named". Burger concluded: "To hold that the act of homosexual sodomy is somehow protected as a fundamental right would be to cast aside millennia of moral teaching." Justice Lewis F. Powell later regretted joining the majority but thought the case of little importance at the time.

The senior dissent, by Justice Harry Blackmun, framed the issue as revolving around the right to privacy. Blackmun's dissent accused the Court of an "almost obsessive focus on homosexual activity" and an "overall refusal to consider the broad principles that have informed our treatment of privacy in specific cases." In response to invocations of religious taboos against homosexuality, Blackmun wrote: "That certain, but by no means all, religious groups condemn the behavior at issue gives the State no license to impose their judgments on the entire citizenry. The legitimacy of secular legislation depends, instead, on whether the State can advance some justification for its law beyond its conformity to religious doctrine."Seventeen years after Bowers v. Hardwick, the Supreme Court directly overruled its decision in Lawrence v. Texas, and held that anti-sodomy laws are unconstitutional. Bowers is now sometimes included in lists of the worst Supreme Court decisions.

The Supreme Court of the United States (SCOTUS) is the highest court in the federal judiciary of the United States. It has ultimate and largely discretionary appellate jurisdiction over all federal and state court cases that involve a point of federal law, and original jurisdiction over a narrow range of cases, specifically "all Cases affecting Ambassadors, other public Ministers and Consuls, and those in which a State shall be Party." The Court holds the power of judicial review, the ability to invalidate a statute for violating a provision of the Constitution. It is also able to strike down presidential directives for violating either the Constitution or statutory law. However, it may act only within the context of a case in an area of law over which it has jurisdiction. The Court may decide cases having political overtones but has ruled that it does not have power to decide non-justiciable political questions.

Established by Article Three of the United States Constitution, the composition and procedures of the Supreme Court were initially established by the 1st Congress through the Judiciary Act of 1789. As later set by the Judiciary Act of 1869, the Court consists of the chief justice of the United States and eight associate justices. Each justice has lifetime tenure, meaning they remain on the Court until they die, retire, resign, or are removed from office. When a vacancy occurs, the president, with the advice and consent of the Senate, appoints a new justice. Each justice has a single vote in deciding the cases argued before the Court. When in majority, the chief justice decides who writes the opinion of the court; otherwise, the most senior justice in the majority assigns the task of writing the opinion.

The Court meets in the Supreme Court Building in Washington, D.C. Its law enforcement arm is the Supreme Court Police.
