Griswold v. Connecticut, 381 U.S. 479 (1965), was a landmark decision of the U.S. Supreme Court in which the Court ruled that the Constitution of the United States protects the liberty of married couples to buy and use contraceptives without government restriction. 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". The court held that the statute was unconstitutional, and that its effect was "to deny disadvantaged citizens ... access to medical assistance and up-to-date information in respect to proper methods of birth control". By a vote of 72, 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 "protected from governmental intrusion".Although the U.S. 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 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.

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.
