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 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 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 "protected from governmental intrusion".

The Supreme Court of the United States (SCOTUS) is the highest court in the federal judiciary of the United States. It has ultimate appellate jurisdiction over all U.S. federal court cases, and over state court cases that turn on questions of U.S. constitutional or federal law. It also has 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.
