Gonzales v. Carhart
The Court upheld the federal Partial-Birth Abortion Ban Act of 2003, ruling that Congress could prohibit a specific method of ending a pregnancy in which a fetus is partially delivered before being killed, even though the law contains no exception for protecting a woman's health.
The decision marked the first time the Court approved a ban on an abortion procedure without a health exception, signaling new room for lawmakers to restrict specific abortion methods despite ongoing medical disagreement over safety.
“Casey, in short, struck a balance. The balance was central to its holding. We now apply its standard to the cases at bar.”
The majority explains it is applying the balance Casey struck between abortion rights and government interests.
How it got here: Federal trial courts in Nebraska and California struck down the Act and permanently blocked its enforcement; the Eighth and Ninth Circuits affirmed, and the government asked the Supreme Court to review both cases.
The Case in Depth
What happened
Congress passed the Partial-Birth Abortion Ban Act in 2003 after the Supreme Court had struck down a similar Nebraska law in 2000. The Act criminalized a specific method some doctors used to perform second-trimester abortions, in which the fetus is partially delivered before being killed, unless necessary to save the mother's life. Groups of abortion doctors and abortion-rights organizations sued, arguing the law was unconstitutionally vague, banned more procedures than intended, and lacked a health exception.
The question before the Court
Could Congress ban a specific late-term abortion procedure nationwide without including any exception to protect a woman's health?
The Court's answer
No — the Court ruled that Congress could ban this specific abortion procedure nationwide even without a health exception, upholding the Partial-Birth Abortion Ban Act. The Court read the law narrowly to cover only a specific method of partially delivering and then killing a fetus, not the more common abortion procedure used in most second-trimester abortions, and found the law gave doctors clear enough notice of what was illegal.
On the health-exception question, the Court acknowledged doctors disagreed about whether the banned procedure was ever medically necessary, but concluded that this kind of medical uncertainty doesn't stop lawmakers from regulating, especially since other, unbanned abortion methods remained available as safe alternatives. The Court also said future challenges based on specific medical circumstances should be brought case-by-case rather than as one broad challenge to the whole law.

Why it matters
Doctors who perform second-trimester abortions can now face federal criminal charges for using the banned procedure, even if they believe it is medically safer for a particular patient, unless the woman's life is at risk. The ruling gives Congress and state legislatures more latitude to regulate specific abortion methods when doctors disagree about safety, without being required to write in a health exception.
What changes now
This is a final merits decision, not a temporary order. The judgments of the Eighth and Ninth Circuits were reversed, meaning the injunctions blocking enforcement of the Act were lifted and the law took effect nationwide. The Court left open the possibility that doctors or patients could bring narrower, as-applied lawsuits if they could show the banned procedure is medically necessary in specific, well-defined circumstances.
What this does not decide
The Court did not decide that Congress' factual findings supporting the Act were accurate — it acknowledged some findings were incorrect or outdated. It also left the door open to future as-applied challenges by patients or doctors who can show the procedure is necessary in specific circumstances, rather than closing off all constitutional challenges to the law.
Concurrences and dissents
Concurrence — Justice Thomas
Justice Thomas, joined by Justice Scalia, agreed the majority correctly applied existing abortion precedent, but reiterated his view that the Court's abortion cases, including Roe and Casey, have no basis in the Constitution at all. He also noted that whether Congress had authority under the Commerce Clause to pass the Act was not before the Court because no party raised it.
Dissent — Justice Ginsburg
“Today’s decision is alarming. It refuses to take Casey and Stenberg seriously.”Ginsburg's opening objection that the ruling departs from the Court's own precedents.
Justice Ginsburg argued the ruling abandons the Court's consistent requirement that abortion restrictions include a health exception whenever substantial medical authority shows the ban could endanger women's health. She contended the majority ignored detailed trial-court findings favoring the banned procedure's safety in some cases, blurred the previability/postviability line, and rested on unsupported moral assumptions about women's regret rather than genuine interests in protecting fetal life or maternal health. She would have affirmed the lower courts and struck down the law.
How the Court got there
The legal reasoning, step by step
- The Court applied the framework from Planned Parenthood v. Casey, which allows abortion regulations before viability as long as they don't impose an 'undue burden' — meaning a law can't place a substantial obstacle in the path of a woman seeking an abortion, but the government can still express respect for fetal life through regulation.
- The Court first examined whether the law was unconstitutionally vague, a doctrine requiring that a criminal statute give people fair notice of what's illegal and not invite arbitrary enforcement. It found the Act's specific anatomical checkpoints and required intent (scienter) gave doctors clear enough notice and limited prosecutors' discretion.
- The Court then decided whether the law's wording actually banned the common second-trimester abortion method (D&E) in addition to the narrower 'intact' procedure Congress meant to target. Unlike the Nebraska law struck down in the Court's earlier Stenberg decision, this Act required delivery of the fetus to specific anatomical landmarks and a separate deliberate act to kill it, so the Court read the text as reaching only the intact procedure, not standard D&E.
- Turning to whether the law needed a health exception, the Court found that the medical evidence on whether the banned procedure was ever necessary to protect a woman's health was genuinely contested, with experts and trial courts disagreeing.
- The Court held that when this kind of medical uncertainty exists, legislatures may still act, especially because safer alternative procedures remained legal and available, so requiring a health exception was not constitutionally necessary here.
- The Court also concluded that challenges to abortion laws should ordinarily be brought as narrow, case-by-case ('as-applied') challenges rather than broad, facial ones, reserving the latter for situations where the law's own text shows unconstitutionality in all or most cases.

The Court found this federal law different enough in wording from the Nebraska law struck down in Stenberg to be constitutional.
Reaffirms Planned Parenthood of Southeastern Pa. v. Casey (505 U. S. 833)
The Court applied Casey's undue-burden standard and its recognition of the government's interest in fetal life.

Noted as already overruled by Casey for undervaluing the state's interest in potential life.
