Roe v. Wade Case Summary: Ruling, Casey, and Dobbs

Roe v. Wade was the 1973 Supreme Court decision that recognized a constitutional right to end a pregnancy before fetal viability. The Court ruled 7–2 that a Texas law criminalizing nearly all abortions violated a right to privacy grounded in the Fourteenth Amendment’s Due Process Clause. That ruling governed abortion law in the United States for almost fifty years. The Court narrowed it in 1992 in Planned Parenthood v. Casey and overruled it entirely in 2022 in Dobbs v. Jackson Women’s Health Organization. This case summary of Roe v. Wade walks through what the law was, what the Court held, and how the decision was later dismantled.

The Texas Law and the Plaintiff

The plaintiff was Norma McCorvey, a Texas resident who filed suit in 1970 under the pseudonym “Jane Roe” after being unable to obtain an abortion in Texas. She never received the procedure; she gave birth and placed the child for adoption before the case was resolved. The defendant, Henry Wade, was the district attorney of Dallas County, responsible for enforcing the criminal laws at issue.¹

The statutes she challenged dated back to 1854. Under Article 1191 of the Texas Penal Code, performing or attempting an abortion was punishable by two to five years in prison. Article 1196 allowed a single exception: the procedure was permitted on a doctor’s advice to save the mother’s life. Every other reason was a criminal offense.²

The Constitutional Argument

Roe’s constitutional theory built on Griswold v. Connecticut, a 1965 decision striking down a state ban on contraceptives for married couples. In Griswold, Justice William O. Douglas wrote that several amendments in the Bill of Rights cast “penumbras” that together create “zones of privacy” the government cannot enter.³

Roe’s team argued that this privacy right extended to a woman’s decision about whether to continue a pregnancy. They pointed to the Ninth Amendment, which says the listing of specific rights in the Constitution does not exhaust the rights people hold, and to the Fourteenth Amendment’s Due Process Clause, which protects personal decisions from arbitrary state interference. The argument was not that the Constitution mentions abortion. It was that the constitutional structure already protects a zone of private medical decision-making, and that a criminal ban on abortion reaches into it.¹

What the Court Held in 1973

Justice Harry Blackmun wrote the majority opinion, joined by six other justices. Its central holding was that the Due Process Clause of the Fourteenth Amendment contains a right to privacy “broad enough to encompass a woman’s decision whether or not to terminate her pregnancy.” Because this qualified as a fundamental right, the Court applied strict scrutiny: any state restriction had to be narrowly tailored to serve a compelling government interest.⁴

The right was not absolute. The Court recognized two state interests that grow stronger as pregnancy progresses: protecting the health of the pregnant woman and protecting what the majority called “potential life.” A blanket ban failed because it treated every stage of pregnancy the same.⁵

The Trimester Framework

To translate that balance into a rule states could apply, the Court divided pregnancy into three stages:

During the first trimester, the decision belonged to the woman and her physician. The state could not intervene.⁵
During the second trimester, the state could regulate the procedure in ways reasonably related to protecting the woman’s health, such as facility licensing.
After viability, when a fetus could survive outside the womb, the state’s interest in potential life became compelling, and the state could regulate or ban abortion so long as it kept an exception for the life or health of the mother.¹

The practical effect was sweeping. Abortion laws in most states did not fit within these limits, and the ruling invalidated them.

The Dissents

Justices Byron White and William Rehnquist wrote separately in dissent. White found “nothing in the language or history of the Constitution” to support the majority’s conclusion and called the ruling “an improvident and extravagant exercise of the power of judicial review.” Rehnquist argued that the majority had stretched the Due Process Clause beyond its original purpose and that the trimester framework read like a piece of legislation the Court had no business drafting. Both believed the question belonged to state legislatures.²

The Companion Case: Doe v. Bolton

On the same day, the Court decided Doe v. Bolton, a challenge to a more detailed Georgia abortion statute. Where Roe established the broad right, Doe defined a critical term. Justice Blackmun, writing again for the majority, held that a physician’s medical judgment about the “health of the mother” could take account of “all factors — physical, emotional, psychological, familial, and the woman’s age — relevant to the wellbeing of the patient.”⁶

The Court also struck down several procedural hurdles in the Georgia statute, including a requirement that abortions occur only in accredited hospitals, a mandatory hospital committee approval, and confirmation by two additional doctors.⁶

How Casey Changed the Rule in 1992

For nearly two decades, states tested Roe with increasingly specific regulations. In 1992, the Supreme Court revisited the framework in Planned Parenthood of Southeastern Pennsylvania v. Casey. The Court kept the core of Roe but rebuilt the machinery around it. It abandoned the trimester framework and drew a single line at viability. It replaced strict scrutiny with an “undue burden” standard: a pre-viability restriction was unconstitutional only if it placed a “substantial obstacle” in the path of a woman seeking an abortion.⁷

Applying that standard, the Court upheld most of Pennsylvania’s restrictions, including informed-consent and 24-hour waiting-period requirements and parental consent for minors with a judicial bypass. It struck down a spousal-notification provision, finding it a substantial obstacle for women in abusive relationships. Casey preserved a constitutional right to abortion before viability but opened the door to a wide range of state regulations that the original trimester framework would have blocked.⁷

How Dobbs Overturned Roe in 2022

On June 24, 2022, the Court decided Dobbs v. Jackson Women’s Health Organization and overruled both Roe and Casey. Justice Samuel Alito, writing for the majority, held that “the Constitution does not confer a right to abortion” and that authority to regulate the procedure belongs to “the people and their elected representatives.”⁸

The majority applied a historical test used to evaluate unenumerated rights under the Due Process Clause: only rights “deeply rooted in this Nation’s history and tradition” qualify for constitutional protection. Alito recounted centuries of abortion restrictions and noted that when the Fourteenth Amendment was ratified in 1868, a supermajority of states had statutes criminalizing abortion at all stages. On that basis, the majority concluded the right recognized in Roe lacked the historical foundation the test requires.⁸

Regulation of abortion returned to individual states. The trimester framework, the viability line, and the undue-burden standard no longer apply as a matter of federal constitutional law. A large majority of states have since enacted bans or significant restrictions; others have codified protections in state law or state constitutions.

What Dobbs Left Unsettled

Two questions remain live after Dobbs.

The first concerns other rights built on the same constitutional foundation. The Dobbs majority wrote that the opinion “concerns the constitutional right to abortion and no other right” and that “[n]othing in this opinion should be understood to cast doubt on precedents that do not concern abortion.” Justice Clarence Thomas took the opposite view in a concurrence, arguing that the Court should “reconsider all of this Court’s substantive due process precedents” and naming Griswold v. Connecticut (contraception), Lawrence v. Texas (same-sex intimacy), and Obergefell v. Hodges (same-sex marriage). No other justice joined that concurrence.⁸

The second involves federal emergency-care law. The Emergency Medical Treatment and Labor Act requires hospitals that accept Medicare to provide stabilizing treatment for emergency medical conditions. In states that ban abortion, a conflict arises when a pregnant patient needs the procedure to prevent serious health consequences short of death. The Supreme Court took up that collision in Moyle v. United States in June 2024 but did not resolve it. The Court dismissed the case without reaching the merits, vacating a stay and letting a lower-court injunction take effect in Idaho. The injunction prevents Idaho from enforcing its ban when a termination is needed to prevent serious health harms, but it applies only there and leaves the broader question for future litigation.⁹
