The Supreme Court of the United States delivers its decisions in Roe v. Wade and Doe v. Bolton, legalizing elective abortion in all fifty states.

Roe v. Wade, 410 U.S. 113 (1973), was a landmark decision of the U.S. Supreme Court in which the Court ruled that the Constitution of the United States protects a pregnant woman's liberty to choose to have an abortion without excessive government restriction. The decision struck down many U.S. federal and state abortion laws. Roe fueled an ongoing abortion debate in the United States about whether, or to what extent, abortion should be legal, who should decide the legality of abortion, and what the role of moral and religious views in the political sphere should be. It also shaped debate concerning which methods the Supreme Court should use in constitutional adjudication.

The decision involved the case of Norma McCorveyknown by the legal pseudonym "Jane Roe"who in 1969 became pregnant with her third child. McCorvey wanted an abortion but lived in Texas, where abortion was illegal except when necessary to save the mother's life. Her attorneys, Sarah Weddington and Linda Coffee, filed a lawsuit on her behalf in U.S. federal court against her local district attorney, Henry Wade, alleging that Texas's abortion laws were unconstitutional. A three-judge panel of the U.S. District Court for the Northern District of Texas heard the case and ruled in her favor. Yet the District Court ruled against two others who were also represented by Weddington and Coffee alongside McCorvey. Weddington and Coffee appealed their partial loss to the U.S. Supreme Court, while at the same time Wade cross-appealed his partial loss to the Supreme Court.

In January 1973, the Supreme Court issued a 72 decision in McCorvey's favor ruling that the Due Process Clause of the Fourteenth Amendment to the United States Constitution provides a "right to privacy" that protects a pregnant woman's right to choose whether to have an abortion. It also ruled that this right is not absolute and must be balanced against governments' interests in protecting women's health and prenatal life. The Court resolved this balancing test by tying state regulation of abortion to the three trimesters of pregnancy: during the first trimester, governments could not prohibit abortions at all; during the second trimester, governments could require reasonable health regulations; during the third trimester, abortions could be prohibited entirely so long as the laws contained exceptions for cases when they were necessary to save the life or health of the mother. The Court classified the right to choose to have an abortion as "fundamental", which required courts to evaluate challenged abortion laws under the "strict scrutiny" standard, the highest level of judicial review in the United States.The Court's ruling in Roe was criticized by some in the legal community, and some called the decision an example of judicial activism. The Supreme Court revisited and modified Roe's legal rulings in its 1992 decision Planned Parenthood v. Casey. In Casey, the Court reaffirmed Roe's holding that a woman's right to choose to have an abortion is constitutionally protected, but overruled Roe's strict scrutiny standard for reviewing abortion restrictions and abandoned Roe's trimester framework in favor of a standard based on fetal viability.On May 2, 2022, Politico obtained a leaked initial draft majority opinion penned by Justice Samuel Alito indicating that the Supreme Court is prepared to overturn Roe and Casey in a pending final decision on Dobbs v. Jackson Women's Health Organization, expected to be issued by June 2022. A press release from Chief Justice John Roberts the following day confirmed the authenticity of the leaked document, but stated that the draft "does not represent a decision by the Court or the final position of any member on the issues in the case".

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.
