Abortion is banned in parts of the United States because the Supreme Court’s 2022 ruling in Dobbs v. Jackson Women’s Health Organization eliminated the federal constitutional right to the procedure and handed the question back to state legislatures. For nearly 50 years, Roe v. Wade and Planned Parenthood v. Casey had blocked states from outlawing abortion before fetal viability. Once that federal floor disappeared, 13 states with pre-written bans, dormant pre-Roe statutes, or newly passed restrictions began enforcing them, and a procedure that is routine medicine in one state became a felony across the border.
The Dobbs Ruling and Its Reasoning
The legal source of every current state ban is Dobbs v. Jackson Women’s Health Organization, decided in June 2022. The case started as a challenge to Mississippi’s 15-week ban, but the Court used it to reconsider whether the Constitution protects abortion at all. The majority concluded it does not, overruling both Roe and Casey and returning the authority to regulate abortion to state governments.1Supreme Court of the United States. Dobbs v. Jackson Women’s Health Organization
The reasoning rests on a test the Court applies to rights not spelled out in the Constitution. Under that test, an unenumerated right qualifies for protection under the Fourteenth Amendment’s Due Process Clause only if it is “deeply rooted in this Nation’s history and tradition” and “implicit in the concept of ordered liberty.”1Supreme Court of the United States. Dobbs v. Jackson Women’s Health Organization The majority examined what American law said about abortion around 1868, when the Fourteenth Amendment was ratified, and found that most states at the time criminalized the procedure at various stages of pregnancy. From that historical record, the Court concluded abortion was not part of the country’s legal tradition and could not qualify as a constitutionally protected right.
The opinion also separated abortion from other privacy-based rights the Court has recognized under the same clause, such as access to contraception and the right to marry. The distinction turned on what the Court called “potential life.” The majority wrote that abortion “destroys what Roe termed ‘potential life’ and what the law challenged in this case calls an ‘unborn human being,'” and that none of the other privacy precedents “involved the critical moral question posed by abortion.”1Supreme Court of the United States. Dobbs v. Jackson Women’s Health Organization That framing let the Court treat abortion as categorically different from other personal liberties.
The constitutional consequence flows through the Tenth Amendment, which reserves powers not granted to the federal government to the states or the people.2Congress.gov. U.S. Constitution – Tenth Amendment Because the Court concluded the Constitution neither protects nor prohibits abortion, the power to regulate it falls to each state’s legislature. Unless Congress acts or the Constitution is amended, 50 separate legal regimes now govern access.
What the Ruling Took Away
From 1973 until 2022, two decisions set a nationwide baseline. Roe v. Wade held that the Constitution’s protection of privacy covered a person’s decision to end a pregnancy, and that states could not criminalize the procedure outright.3Supreme Court. Jane ROE, et al., Appellants, v. Henry WADE States could regulate later in pregnancy, but before fetal viability, the choice belonged to the patient and their doctor.
Nearly two decades later, Planned Parenthood v. Casey kept the core of Roe while replacing its strict trimester system. States could regulate abortion before viability, but they could not impose an “undue burden,” meaning a law whose purpose or effect was to place a substantial obstacle in a patient’s path.4Justia. Planned Parenthood of Southeastern Pa. v. Casey, 505 U.S. 833 (1992) Under that standard, waiting periods, counseling requirements, and parental notification rules survived, but total bans did not. Dobbs pulled that floor out from under every state at once.
Why Bans Took Effect So Fast
The speed at which abortion became illegal across large parts of the country reflected years of preparation. The most common mechanism was the trigger law: a statute passed while Roe was still in force, designed to activate automatically the moment federal protection disappeared. Several states had these on the books, and they took effect within hours or days of the ruling. Most included only narrow exceptions, typically preventing the death of the pregnant person.
Other states relied on older laws. Some had never repealed abortion bans from the 1800s and early 1900s. Those statutes had been unenforceable for half a century but were never formally removed. When Dobbs cleared the federal barrier, they technically came back to life, and prosecutors in some jurisdictions began enforcing them. Still other states passed entirely new bans after the ruling, and some amended their state constitutions to confirm that no state-level right to abortion exists.
What the Bans Say
Criminal penalties for providers vary sharply. Some states classify performing an abortion as a felony carrying anywhere from several years to life in prison. Others impose financial penalties that can reach six figures per violation. A few have adopted a civil enforcement model that lets private citizens sue anyone who helps someone obtain a prohibited abortion, effectively outsourcing enforcement to individuals rather than prosecutors. In states with bans, clinics closed rapidly and providers who stayed faced career-ending consequences.
Nearly every ban includes at least one exception, but the scope is often narrower than people expect. The most common covers a threat to the pregnant person’s life. “Life-threatening” is a high bar in practice: doctors have reported delaying treatment for dangerous complications such as ectopic pregnancies or severe infections because the legal standard requires them to wait until the patient’s condition deteriorates far enough to qualify.
Exceptions for rape and incest are far less common. Fewer than a dozen states with restrictions include them, and where they exist, they often carry additional requirements such as filing a police report or acting within a narrow gestational window. Exceptions for lethal fetal anomalies exist in roughly a third of states with restrictions. On paper, the carve-outs look broader than they work; the legal risk to providers keeps many from testing the edges.
Where the Legal Fight Has Moved Next
Since Dobbs, the conflict has spread into medication, emergency care, and travel.
Medication Abortion
Mifepristone accounts for the majority of abortions in the country. The FDA approved it in 2000 and has progressively loosened its rules, removing the in-person dispensing requirement and letting certified pharmacies distribute the drug directly. Opponents challenged those decisions in FDA v. Alliance for Hippocratic Medicine, but the Supreme Court unanimously ruled in 2024 that the plaintiffs lacked standing.5Supreme Court of the United States. FDA v. Alliance for Hippocratic Medicine The FDA’s approval survives, but the tension between federal drug approval and state bans does not go away. In states where abortion is banned, mifepristone is effectively prohibited regardless of FDA approval, and some states have specifically criminalized distributing abortion-inducing medication. Federal challenges arguing that FDA approval should preempt state bans are still working through the courts.
Emergency Care Under EMTALA
The Emergency Medical Treatment and Labor Act requires every hospital that accepts Medicare to stabilize any patient arriving with a medical emergency. The unresolved question is whether that duty requires hospitals in ban states to provide an abortion when it is the necessary stabilizing treatment. The Biden administration issued guidance in 2022 saying it did and that federal law preempted conflicting state bans. Idaho challenged the guidance, and the Supreme Court took up Moyle v. United States but dismissed it in June 2024 without deciding the merits, leaving a lower-court injunction in place.6Supreme Court of the United States. Moyle v. United States In June 2025, the federal government rescinded the 2022 guidance while affirming that EMTALA itself still requires stabilizing care for pregnant patients in emergencies.7CMS. CMS Statement on Emergency Medical Treatment and Labor Act (EMTALA) Without explicit guidance protecting emergency abortions, many hospitals in ban states delay care rather than risk prosecution.
Interstate Travel and Shield Laws
The constitutional right to interstate travel is well established, and no state has successfully enforced a direct ban on residents leaving to obtain an abortion. But some jurisdictions have taken indirect steps. More than a dozen local governments have enacted ordinances restricting the use of local roads for travel to obtain an abortion, relying on private lawsuits rather than criminal prosecution. A few state legislatures have criminalized helping someone, particularly a minor, travel for an abortion, including providing transportation, information, or financial assistance.
Roughly 19 states and the District of Columbia have passed “shield laws” going the other way. These block cooperation with out-of-state investigations, prevent extradition of providers, shield patient records from subpoenas, and protect providers from professional discipline or civil liability for care that was legal where it happened. Some also specifically protect telehealth providers who prescribe medication abortion to patients in ban states.
Voters at the Ballot Box
Voters have consistently chosen to protect abortion rights when the question is put directly to them, including in politically conservative states. Since 2022, voters in at least 11 states have approved ballot measures establishing or strengthening state constitutional protections. California, Michigan, and Vermont passed such measures in 2022, followed by Ohio in 2023, and Arizona, Colorado, Maryland, Missouri, Montana, Nevada, and New York in 2024. Missouri’s result stood out because the state had one of the earliest and most restrictive trigger bans. These measures generally establish a state constitutional right to make reproductive decisions up to viability or when necessary to protect the patient’s health, effectively overriding existing state bans.
What This Means for Other Rights
The Dobbs majority insisted that its reasoning applies only to abortion. The opinion stated that “nothing in this opinion should be understood to cast doubt on precedents that do not concern abortion,” pointing to abortion’s involvement with potential life as the distinguishing factor.1Supreme Court of the United States. Dobbs v. Jackson Women’s Health Organization Rights to contraception, private consensual intimacy, and same-sex marriage rest on the same substantive due process doctrine the Court used to strike down abortion protections.
Not every justice accepted the reassurance. Justice Thomas wrote a concurrence calling on the Court to “reconsider all of this Court’s substantive due process precedents,” specifically naming Griswold v. Connecticut, Lawrence v. Texas, and Obergefell v. Hodges.1Supreme Court of the United States. Dobbs v. Jackson Women’s Health Organization No other justice joined that concurrence, and the majority opinion directly contradicts it. Whether the “potential life” distinction proves durable enough to keep those other precedents intact is a question the Court will almost certainly face again.
