GONZALES, ATTORNEY GENERAL v. CARHART ET AL.
CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR
THE EIGHTH CIRCUIT
No. 05–380. Argued November 8, 2006—Decided April 18, 2007*
Following this Court’s Stenberg v. Carhart, 530 U. S. 914, decision that
Nebraska’s “partial birth abortion” statute violated the Federal Con
stitution, as interpreted in Planned Parenthood of Southeastern Pa.
v. Casey, 505 U. S. 833, and Roe v. Wade, 410 U. S. 113, Congress
passed the Partial-Birth Abortion Ban Act of 2003 (Act) to proscribe a
particular method of ending fetal life in the later stages of pregnancy.
The Act does not regulate the most common abortion procedures used
in the first trimester of pregnancy, when the vast majority of abor
tions take place. In the usual second-trimester procedure, “dilation
and evacuation” (D&E), the doctor dilates the cervix and then inserts
surgical instruments into the uterus and maneuvers them to grab the
fetus and pull it back through the cervix and vagina. The fetus is
usually ripped apart as it is removed, and the doctor may take 10 to
15 passes to remove it in its entirety. The procedure that prompted
the federal Act and various state statutes, including Nebraska’s, is a
variation of the standard D&E, and is herein referred to as “intact
D&E.” The main difference between the two procedures is that in in
tact D&E a doctor extracts the fetus intact or largely intact with only
a few passes, pulling out its entire body instead of ripping it apart.
In order to allow the head to pass through the cervix, the doctor typi
cally pierces or crushes the skull.
The Act responded to Stenberg in two ways. First, Congress found
that unlike this Court in Stenberg, it was not required to accept
the District Court’s factual findings, and that there was a moral,

Syllabus
medical, and ethical consensus that partial-birth abortion is a grue
some and inhumane procedure that is never medically necessary and
should be prohibited. Second, the Act’s language differs from that of
the Nebraska statute struck down in Stenberg. Among other things,
the Act prohibits “knowingly perform[ing] a partial-birth abortion . . .
that is [not] necessary to save the life of a mother,” 18 U. S. C.
§1531(a). It defines “partial-birth abortion,” §1531(b)(1), as a proce
dure in which the doctor: “(A) deliberately and intentionally vaginally
delivers a living fetus until, in the case of a head-first presentation,
the entire fetal head is outside the [mother’s] body . . . , or, in the case
of breech presentation, any part of the fetal trunk past the navel is
outside the [mother’s] body . . . , for the purpose of performing an
overt act that the person knows will kill the partially delivered living
fetus”; and “(B) performs the overt act, other than completion of de
livery, that kills the fetus.”
In No. 05–380, respondent abortion doctors challenged the Act’s
constitutionality on its face, and the Federal District Court granted a
permanent injunction prohibiting petitioner Attorney General from
enforcing the Act in all cases but those in which there was no dispute
the fetus was viable. The court found the Act unconstitutional be
cause it (1) lacked an exception allowing the prohibited procedure
where necessary for the mother’s health and (2) covered not merely
intact D&E but also other D&Es. Affirming, the Eighth Circuit
found that a lack of consensus existed in the medical community as to
the banned procedure’s necessity, and thus Stenberg required legisla
tures to err on the side of protecting women’s health by including a
health exception. In No. 05–1382, respondent abortion advocacy
groups brought suit challenging the Act. The District Court enjoined
the Attorney General from enforcing the Act, concluding it was un
constitutional on its face because it (1) unduly burdened a woman’s
ability to choose a second-trimester abortion, (2) was too vague, and
(3) lacked a health exception as required by Stenberg. The Ninth
Circuit agreed and affirmed.
Held: Respondents have not demonstrated that the Act, as a facial mat
ter, is void for vagueness, or that it imposes an undue burden on a
woman’s right to abortion based on its overbreadth or lack of a health
exception. Pp. 14–39.
1. The Casey Court reaffirmed what it termed Roe’s three-part “es
sential holding”: First, a woman has the right to choose to have an
abortion before fetal viability and to obtain it without undue interfer
ence from the State. Second, the State has the power to restrict abor
tions after viability, if the law contains exceptions for pregnancies
endangering the woman’s life or health. And third, the State has le
gitimate interests from the pregnancy’s outset in protecting the
Cite as: 550 U. S. ____ (2007) 3
Syllabus
health of the woman and the life of the fetus that may become a
child. 505 U. S., at 846. Though all three are implicated here, it is
the third that requires the most extended discussion. In deciding
whether the Act furthers the Government’s legitimate interest in pro
tecting fetal life, the Court assumes, inter alia, that an undue bur
den on the previability abortion right exists if a regulation’s “purpose
or effect is to place a substantial obstacle in the [woman’s] path,” id.,
at 878, but that “[r]egulations which do no more than create a struc
tural mechanism by which the State . . . may express profound re
spect for the life of the unborn are permitted, if they are not a sub
stantial obstacle to the woman’s exercise of the right to choose,” id.,
at 877. Casey struck a balance that was central to its holding, and
the Court applies Casey’s standard here. A central premise of Casey’s
joint opinion—that the government has a legitimate, substantial in
terest in preserving and promoting fetal life—would be repudiated
were the Court now to affirm the judgments below. Pp. 14–16.
2. The Act, on its face, is not void for vagueness and does not im
pose an undue burden from any overbreadth. Pp. 16–26.
(a) The Act’s text demonstrates that it regulates and proscribes
performing the intact D&E procedure. First, since the doctor must
“vaginally delive[r] a living fetus,” §1531(b)(1)(A), the Act does not
restrict abortions involving delivery of an expired fetus or those not
involving vaginal delivery, e.g., hysterotomy or hysterectomy. And it
applies both previability and postviability because, by common un
derstanding and scientific terminology, a fetus is a living organism
within the womb, whether or not it is viable outside the womb. Sec
ond, because the Act requires the living fetus to be delivered to a spe
cific anatomical landmark depending on the fetus’ presentation, ibid.,
an abortion not involving such partial delivery is permitted. Third,
because the doctor must perform an “overt act, other than completion
of delivery, that kills the partially delivered fetus,” §1531(b)(1)(B),
the “overt act” must be separate from delivery. It must also occur af
ter delivery to an anatomical landmark, since killing “the partially
delivered” fetus, when read in context, refers to a fetus that has been
so delivered, ibid. Fourth, given the Act’s scienter requirements, de
livery of a living fetus past an anatomical landmark by accident or
inadvertence is not a crime because it is not “deliberat[e] and inten
tiona[l], §1531(b)(1)(A). Nor is such a delivery prohibited if the fetus
[has not] been delivered “for the purpose of performing an overt act
that the [doctor] knows will kill [it].” Ibid. Pp. 16–18.
(b) The Act is not unconstitutionally vague on its face. It satis
fies both requirements of the void-for-vagueness doctrine. First, it
provides doctors “of ordinary intelligence a reasonable opportunity to
know what is prohibited,” Grayned v. City of Rockford, 408 U. S. 104,
4 GONZALES v. CARHART
Syllabus
108, setting forth “relatively clear guidelines as to prohibited con
duct” and providing “objective criteria” to evaluate whether a doctor
has performed a prohibited procedure, Posters ‘N’ Things, Ltd. v.
United States, 511 U. S. 513, 525–526. Second, it does not encourage
arbitrary or discriminatory enforcement. Kolender v. Lawson, 461
U. S. 352, 357. Its anatomical landmarks “establish minimal guide
lines to govern law enforcement,” Smith v. Goguen, 415 U. S. 566,
574, and its scienter requirements narrow the scope of its prohibition
and limit prosecutorial discretion, see Kolender, supra, at 358. Re
spondents’ arbitrary enforcement arguments, furthermore, are
somewhat speculative, since this is a preenforcement challenge.
Pp. 18–20.
(c) The Court rejects respondents’ argument that the Act imposes
an undue burden, as a facial matter, because its restrictions on sec
ond-trimester abortions are too broad. Pp. 20–26.
(i) The Act’s text discloses that it prohibits a doctor from inten
tionally performing an intact D&E. Its dual prohibitions correspond
with the steps generally undertaken in this procedure: The doctor (1)
delivers the fetus until its head lodges in the cervix, usually past the
anatomical landmark for a breech presentation, see §1531(b)(1)(A),
and (2) proceeds to the overt act of piercing or crushing the fetal skull
after the partial delivery, see §1531(b)(1)(B). The Act’s scienter re
quirements limit its reach to those physicians who carry out the in
tact D&E, with the intent to undertake both steps at the outset. The
Act excludes most D&Es in which the doctor intends to remove the
fetus in pieces from the outset. This interpretation is confirmed by
comparing the Act with the Nebraska statute in Stenberg. There, the
Court concluded that the statute encompassed D&E, which “often in
volve[s] a physician pulling a ‘substantial portion’ of a still living fe
tus . . . , say, an arm or leg, into the vagina prior to the death of the
fetus,” 530 U. S., at 939, and rejected the Nebraska Attorney Gen
eral’s limiting interpretation that the statute’s reference to a “proce
dure” that “kill[s] the unborn child” was to a distinct procedure, not
to the abortion procedure as a whole, id., at 943. It is apparent Con
gress responded to these concerns because the Act adopts the phrase
“delivers a living fetus,” 18 U. S. C. §1531(b)(1)(A), instead of “ ‘deliv
ering . . . a living unborn child, or a substantial portion thereof,’ ” 530
U. S., at 938, thereby targeting extraction of an entire fetus rather
than removal of fetal pieces; identifies specific anatomical landmarks
to which the fetus must be partially delivered, §1531(b)(1)(A), thereby
clarifying that the removal of a small portion of the fetus is not pro
hibited; requires the fetus to be delivered so that it is partially “out
side the [mother’s] body,” §1531(b)(1)(A), thereby establishing that
delivering a substantial portion of the fetus into the vagina would not
Cite as: 550 U. S. ____ (2007) 5
Syllabus
subject a doctor to criminal sanctions; and adds the overt-act re
quirement, §1531(b)(1), thereby making the distinction the Nebraska
statute failed to draw (but the Nebraska Attorney General advanced).
Finally, the canon of constitutional avoidance, see, e.g., Edward J.
DeBartolo Corp. v. Florida Gulf Coast Building & Constr. Trades
Council, 485 U. S. 568, 575, extinguishes any lingering doubt. Inter
preting the Act not to prohibit standard D&E is the most reasonable
reading and understanding of its terms. Pp. 20–24.
(ii) Respondents’ contrary arguments are unavailing. The con
tention that any D&E may result in the delivery of a living fetus be
yond the Act’s anatomical landmarks because doctors cannot predict
the amount the cervix will dilate before the procedure does not take
account of the Act’s intent requirements, which preclude liability for
an accidental intact D&E. The evidence supports the legislative de
termination that an intact delivery is almost always a conscious
choice rather than a happenstance, belying any claim that a standard
D&E cannot be performed without intending or foreseeing an intact
D&E. That many doctors begin every D&E with the objective of re
moving the fetus as intact as possible based on their belief that this is
safer does not prove, as respondents suggest, that every D&E might
violate the Act, thereby imposing an undue burden. It demonstrates
only that those doctors must adjust their conduct to the law by not
attempting to deliver the fetus to an anatomical landmark. Respon
dents have not shown that requiring doctors to intend dismember
ment before such a delivery will prohibit the vast majority of D&E
abortions. Pp. 24–26.
3. The Act, measured by its text in this facial attack, does not im
pose a “substantial obstacle” to late-term, but previability, abortions,
as prohibited by the Casey plurality, 505 U. S., at 878. Pp. 26–37.
(a) The contention that the Act’s congressional purpose was to
create such an obstacle is rejected. The Act’s stated purposes are
protecting innocent human life from a brutal and inhumane proce
dure and protecting the medical community’s ethics and reputation.
The government undoubtedly “has an interest in protecting the in
tegrity and ethics of the medical profession.” Washington v. Glucks
berg, 521 U. S. 702, 731. Moreover, Casey reaffirmed that the gov
ernment may use its voice and its regulatory authority to show its
profound respect for the life within the woman. See, e.g., 505 U. S.,
at 873. The Act’s ban on abortions involving partial delivery of a liv
ing fetus furthers the Government’s objectives. Congress determined
that such abortions are similar to the killing of a newborn infant.
This Court has confirmed the validity of drawing boundaries to pre
vent practices that extinguish life and are close to actions that are
condemned. Glucksberg, supra, at 732–735, and n. 23. The Act also
6 GONZALES v. CARHART
Syllabus
recognizes that respect for human life finds an ultimate expression in
a mother’s love for her child. Whether to have an abortion requires a
difficult and painful moral decision, Casey, 505 U. S., at 852–853,
which some women come to regret. In a decision so fraught with
emotional consequence, some doctors may prefer not to disclose pre
cise details of the abortion procedure to be used. It is, however, pre
cisely this lack of information that is of legitimate concern to the
State. Id., at 873. The State’s interest in respect for life is advanced
by the dialogue that better informs the political and legal systems,
the medical profession, expectant mothers, and society as a whole of
the consequences that follow from a decision to elect a late-term abor
tion. The objection that the Act accomplishes little because the stan
dard D&E is in some respects as brutal, if not more, than intact
D&E, is unpersuasive. It was reasonable for Congress to think that
partial-birth abortion, more than standard D&E, undermines the
public’s perception of the doctor’s appropriate role during delivery,
and perverts the birth process. Pp. 26–30.
(b) The Act’s failure to allow the banned procedure’s use where
“ ‘necessary, in appropriate medical judgment, for preservation of the
[mother’s] health,’ ” Ayotte v. Planned Parenthood of Northern New
Eng., 546 U. S. 320, 327–328, does not have the effect of imposing an
unconstitutional burden on the abortion right. The Court assumes
the Act’s prohibition would be unconstitutional, under controlling
precedents, if it “subject[ed] [women] to significant health risks.” Id.,
at 328. Whether the Act creates such risks was, however, a contested
factual question below: The evidence presented in the trial courts and
before Congress demonstrates both sides have medical support for
their positions. The Court’s precedents instruct that the Act can sur
vive facial attack when this medical uncertainty persists. See, e.g.,
Kansas v. Hendricks, 521 U. S. 346, 360, n. 3. This traditional rule is
consistent with Casey, which confirms both that the State has an in
terest in promoting respect for human life at all stages in the preg
nancy, and that abortion doctors should be treated the same as other
doctors. Medical uncertainty does not foreclose the exercise of legis
lative power in the abortion context any more than it does in other
contexts. Other considerations also support the Court’s conclusion,
including the fact that safe alternatives to the prohibited procedure,
such as D&E, are available. In addition, if intact D&E is truly neces
sary in some circumstances, a prior injection to kill the fetus allows a
doctor to perform the procedure, given that the Act’s prohibition only
applies to the delivery of “a living fetus,” 18 U. S. C. §1531(b)(1)(A).
Planned Parenthood of Central Mo. v. Danforth, 428 U. S. 52, 77–79,
distinguished. The Court rejects certain of the parties’ arguments.
On the one hand, the Attorney General’s contention that the Act
Cite as: 550 U. S. ____ (2007) 7
Syllabus
should be upheld based on the congressional findings alone fails be
cause some of the Act’s recitations are factually incorrect and some of
the important findings have been superseded. Also unavailing, how
ever, is respondents’ contention that an abortion regulation must
contain a health exception if “substantial medical authority supports
the proposition that banning a particular procedure could endanger
women’s health, ” Stenberg, 530 U. S., at 938. Interpreting Stenberg
as leaving no margin for legislative error in the face of medical uncer
tainty is too exacting a standard. Marginal safety considerations, in
cluding the balance of risks, are within the legislative competence
where, as here, the regulation is rational and pursues legitimate
ends, and standard, safe medical options are available. Pp. 31–37.
4. These facial attacks should not have been entertained in the first
instance. In these circumstances the proper means to consider excep
tions is by as-applied challenge. Cf. Wisconsin Right to Life, Inc. v.
Federal Election Comm’n, 546 U. S. ___, ___. This is the proper man
ner to protect the woman’s health if it can be shown that in discrete
and well-defined instances a condition has or is likely to occur in
which the procedure prohibited by the Act must be used. No as-
applied challenge need be brought if the Act’s prohibition threatens a
woman’s life, because the Act already contains a life exception. 18

ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF
APPEALS FOR THE NINTH CIRCUIT
[April 18, 2007]
JUSTICE KENNEDY delivered the opinion of the Court.
These cases require us to consider the validity of the
Partial-Birth Abortion Ban Act of 2003 (Act), 18 U. S. C.
§1531 (2000 ed., Supp. IV), a federal statute regulating
abortion procedures. In recitations preceding its operative
provisions the Act refers to the Court’s opinion in Stenberg
v. Carhart, 530 U. S. 914 (2000), which also addressed the
subject of abortion procedures used in the later stages of
pregnancy. Compared to the state statute at issue in
Stenberg, the Act is more specific concerning the instances
2 GONZALES v. CARHART
Opinion of the Court
to which it applies and in this respect more precise in its
coverage. We conclude the Act should be sustained
against the objections lodged by the broad, facial attack
brought against it.
In No. 05–380 (Carhart) respondents are LeRoy
Carhart, William G. Fitzhugh, William H. Knorr, and Jill
L. Vibhakar, doctors who perform second-trimester abor
tions. These doctors filed their complaint against the
Attorney General of the United States in the United
States District Court for the District of Nebraska. They
challenged the constitutionality of the Act and sought a
permanent injunction against its enforcement. Carhart v.
Ashcroft, 331 F. Supp. 2d 805 (2004). In 2004, after a 2
week trial, the District Court granted a permanent injunc
tion that prohibited the Attorney General from enforcing
the Act in all cases but those in which there was no dis
pute the fetus was viable. Id., at 1048. The Court of
Appeals for the Eighth Circuit affirmed. 413 F. 3d 791
(2005). We granted certiorari. 546 U. S. 1169 (2006).
In No. 05–1382 (Planned Parenthood) respondents are
Planned Parenthood Federation of America, Inc., Planned
Parenthood Golden Gate, and the City and County of San
Francisco. The Planned Parenthood entities sought to
enjoin enforcement of the Act in a suit filed in the United
States District Court for the Northern District of Califor
nia. Planned Parenthood Federation of Am. v. Ashcroft,
320 F. Supp. 2d 957 (2004). The City and County of San
Francisco intervened as a plaintiff. In 2004, the District
Court held a trial spanning a period just short of three
weeks, and it, too, enjoined the Attorney General from
enforcing the Act. Id., at 1035. The Court of Appeals for
the Ninth Circuit affirmed. 435 F. 3d 1163 (2006). We
granted certiorari. 547 U. S. ___ (2006).

Opinion of the Court
I
A
The Act proscribes a particular manner of ending fetal
life, so it is necessary here, as it was in Stenberg, to dis
cuss abortion procedures in some detail. Three United
States District Courts heard extensive evidence describing
the procedures. In addition to the two courts involved in
the instant cases the District Court for the Southern
District of New York also considered the constitutionality
of the Act. Nat. Abortion Federation v. Ashcroft, 330
F. Supp. 2d 436 (2004). It found the Act unconstitutional,
id., at 493, and the Court of Appeals for the Second Circuit
affirmed, Nat. Abortion Federation v. Gonzales, 437 F. 3d
278 (2006). The three District Courts relied on similar
medical evidence; indeed, much of the evidence submitted
to the Carhart court previously had been submitted to the
other two courts. 331 F. Supp. 2d, at 809–810. We refer
to the District Courts’ exhaustive opinions in our own
discussion of abortion procedures.
Abortion methods vary depending to some extent on the
preferences of the physician and, of course, on the term of
the pregnancy and the resulting stage of the unborn
child’s development. Between 85 and 90 percent of the
approximately 1.3 million abortions performed each year
in the United States take place in the first three months of
pregnancy, which is to say in the first trimester. Planned
Parenthood, 320 F. Supp. 2d, at 960, and n. 4; App. in No.
05–1382, pp. 45–48. The most common first-trimester
abortion method is vacuum aspiration (otherwise known
as suction curettage) in which the physician vacuums out
the embryonic tissue. Early in this trimester an alterna
tive is to use medication, such as mifepristone (commonly
known as RU–486), to terminate the pregnancy. Nat.
Abortion Federation, supra, at 464, n. 20. The Act does
not regulate these procedures.
Of the remaining abortions that take place each year,
4 GONZALES v. CARHART
Opinion of the Court
most occur in the second trimester. The surgical proce
dure referred to as “dilation and evacuation” or “D&E” is
the usual abortion method in this trimester. Planned
Parenthood, 320 F. Supp. 2d, at 960–961. Although indi
vidual techniques for performing D&E differ, the general
steps are the same.
A doctor must first dilate the cervix at least to the ex
tent needed to insert surgical instruments into the uterus
and to maneuver them to evacuate the fetus. Nat. Abor
tion Federation, supra, at 465; App. in No. 05–1382, at 61.
The steps taken to cause dilation differ by physician and
gestational age of the fetus. See, e.g., Carhart, 331
F. Supp. 2d, at 852, 856, 859, 862–865, 868, 870, 873–874,
876–877, 880, 883, 886. A doctor often begins the dilation
process by inserting osmotic dilators, such as laminaria
(sticks of seaweed), into the cervix. The dilators can be
used in combination with drugs, such as misoprostol, that
increase dilation. The resulting amount of dilation is not
uniform, and a doctor does not know in advance how an
individual patient will respond. In general the longer
dilators remain in the cervix, the more it will dilate. Yet
the length of time doctors employ osmotic dilators varies.
Some may keep dilators in the cervix for two days, while
others use dilators for a day or less. Nat. Abortion Federa
tion, supra, at 464–465; Planned Parenthood, supra, at
961.
After sufficient dilation the surgical operation can com
mence. The woman is placed under general anesthesia or
conscious sedation. The doctor, often guided by ultra
sound, inserts grasping forceps through the woman’s
cervix and into the uterus to grab the fetus. The doctor
grips a fetal part with the forceps and pulls it back
through the cervix and vagina, continuing to pull even
after meeting resistance from the cervix. The friction
causes the fetus to tear apart. For example, a leg might be
ripped off the fetus as it is pulled through the cervix and
Cite as: 550 U. S. ____ (2007) 5
Opinion of the Court
out of the woman. The process of evacuating the fetus
piece by piece continues until it has been completely re
moved. A doctor may make 10 to 15 passes with the for
ceps to evacuate the fetus in its entirety, though some
times removal is completed with fewer passes. Once the
fetus has been evacuated, the placenta and any remaining
fetal material are suctioned or scraped out of the uterus.
The doctor examines the different parts to ensure the
entire fetal body has been removed. See, e.g., Nat. Abor
tion Federation, supra, at 465; Planned Parenthood, supra,
at 962.
Some doctors, especially later in the second trimester,
may kill the fetus a day or two before performing the
surgical evacuation. They inject digoxin or potassium
chloride into the fetus, the umbilical cord, or the amniotic
fluid. Fetal demise may cause contractions and make
greater dilation possible. Once dead, moreover, the fetus’
body will soften, and its removal will be easier. Other
doctors refrain from injecting chemical agents, believing it
adds risk with little or no medical benefit. Carhart, supra,
at 907–912; Nat. Abortion Federation, supra, at 474–475.
The abortion procedure that was the impetus for the
numerous bans on “partial-birth abortion,” including the
Act, is a variation of this standard D&E. See M. Haskell,
Dilation and Extraction for Late Second Trimester Abor
tion (1992), 1 Appellant’s App. in No. 04–3379 (CA8), p.
109 (hereinafter Dilation and Extraction). The medical
community has not reached unanimity on the appropriate
name for this D&E variation. It has been referred to as
“intact D&E,” “dilation and extraction” (D&X), and “intact
D&X.” Nat. Abortion Federation, supra, at 440, n. 2; see
also F. Cunningham et al., Williams Obstetrics 243 (22d
ed. 2005) (identifying the procedure as D&X); Danforth’s
Obstetrics and Gynecology 567 (J. Scott, R. Gibbs, B.
Karlan, & A. Haney eds. 9th ed. 2003) (identifying the
procedure as intact D&X); M. Paul, E. Lichtenberg, L.
6 GONZALES v. CARHART
Opinion of the Court
Borgatta, D. Grimes, & P. Stubblefield, A Clinician’s
Guide to Medical and Surgical Abortion 136 (1999) (identi
fying the procedure as intact D&E). For discussion pur
poses this D&E variation will be referred to as intact
D&E. The main difference between the two procedures is
that in intact D&E a doctor extracts the fetus intact or
largely intact with only a few passes. There are no com
prehensive statistics indicating what percentage of all
D&Es are performed in this manner.
Intact D&E, like regular D&E, begins with dilation of
the cervix. Sufficient dilation is essential for the proce
dure. To achieve intact extraction some doctors thus may
attempt to dilate the cervix to a greater degree. This
approach has been called “serial” dilation. Carhart, supra,
at 856, 870, 873; Planned Parenthood, supra, at 965.
Doctors who attempt at the outset to perform intact D&E
may dilate for two full days or use up to 25 osmotic dila
tors. See, e.g., Dilation and Extraction 110; Carhart,
supra, at 865, 868, 876, 886.
In an intact D&E procedure the doctor extracts the fetus
in a way conducive to pulling out its entire body, instead of
ripping it apart. One doctor, for example, testified:
“If I know I have good dilation and I reach in and
the fetus starts to come out and I think I can accom
plish it, the abortion with an intact delivery, then I
use my forceps a little bit differently. I don’t close
them quite so much, and I just gently draw the tissue
out attempting to have an intact delivery, if possible.”
App. in No. 05–1382, at 74.
Rotating the fetus as it is being pulled decreases the odds
of dismemberment. Carhart, supra, at 868–869; App. in
No. 05–380, pp. 40–41; 5 Appellant’s App. in No. 04–3379
(CA8), p. 1469. A doctor also “may use forceps to grasp a
fetal part, pull it down, and re-grasp the fetus at a higher
level—sometimes using both his hand and a forceps—to

Opinion of the Court
exert traction to retrieve the fetus intact until the head is
lodged in the [cervix].” Carhart, 331 F. Supp. 2d, at 886–
887.
Intact D&E gained public notoriety when, in 1992, Dr.
Martin Haskell gave a presentation describing his method
of performing the operation. Dilation and Extraction 110–
111. In the usual intact D&E the fetus’ head lodges in the
cervix, and dilation is insufficient to allow it to pass. See,
e.g., ibid.; App. in No. 05–380, at 577; App. in No. 05–
1382, at 74, 282. Haskell explained the next step as
follows:
“ ‘At this point, the right-handed surgeon slides the
fingers of the left [hand] along the back of the fetus
and “hooks” the shoulders of the fetus with the index
and ring fingers (palm down).
“ ‘While maintaining this tension, lifting the cervix
and applying traction to the shoulders with the fin
gers of the left hand, the surgeon takes a pair of blunt
curved Metzenbaum scissors in the right hand. He
carefully advances the tip, curved down, along the
spine and under his middle finger until he feels it con
tact the base of the skull under the tip of his middle
finger.
“ ‘[T]he surgeon then forces the scissors into the base
of the skull or into the foramen magnum. Having
safely entered the skull, he spreads the scissors to
enlarge the opening.
“ ‘The surgeon removes the scissors and introduces a
suction catheter into this hole and evacuates the skull
contents. With the catheter still in place, he applies
traction to the fetus, removing it completely from the
patient.’ ” H. R. Rep. No. 108–58, p. 3 (2003).
This is an abortion doctor’s clinical description. Here is
another description from a nurse who witnessed the same
method performed on a 26½-week fetus and who testified
8 GONZALES v. CARHART
Opinion of the Court
before the Senate Judiciary Committee:
“ ‘Dr. Haskell went in with forceps and grabbed the
baby’s legs and pulled them down into the birth canal.
Then he delivered the baby’s body and the arms—
everything but the head. The doctor kept the head
right inside the uterus. . . .
“ ‘The baby’s little fingers were clasping and un
clasping, and his little feet were kicking. Then the
doctor stuck the scissors in the back of his head, and
the baby’s arms jerked out, like a startle reaction, like
a flinch, like a baby does when he thinks he is going to
fall.
“ ‘The doctor opened up the scissors, stuck a high-
powered suction tube into the opening, and sucked the
baby’s brains out. Now the baby went completely
limp. . . .
“ ‘He cut the umbilical cord and delivered the pla
centa. He threw the baby in a pan, along with the
placenta and the instruments he had just used.’ ”
Ibid.
Dr. Haskell’s approach is not the only method of killing
the fetus once its head lodges in the cervix, and “the proc
ess has evolved” since his presentation. Planned Parent
hood, 320 F. Supp. 2d, at 965. Another doctor, for exam
ple, squeezes the skull after it has been pierced “so that
enough brain tissue exudes to allow the head to pass
through.” App. in No. 05–380, at 41; see also Carhart,
supra, at 866–867, 874. Still other physicians reach into
the cervix with their forceps and crush the fetus’ skull.
Carhart, supra, at 858, 881. Others continue to pull the
fetus out of the woman until it disarticulates at the neck,
in effect decapitating it. These doctors then grasp the
head with forceps, crush it, and remove it. Id., at 864,
878; see also Planned Parenthood, supra, at 965.
Some doctors performing an intact D&E attempt to
Cite as: 550 U. S. ____ (2007) 9
Opinion of the Court
remove the fetus without collapsing the skull. See
Carhart, supra, at 866, 869. Yet one doctor would not
allow delivery of a live fetus younger than 24 weeks be
cause “the objective of [his] procedure is to perform an
abortion,” not a birth. App. in No. 05–1382, at 408–409.
The doctor thus answered in the affirmative when asked
whether he would “hold the fetus’ head on the internal
side of the [cervix] in order to collapse the skull” and kill
the fetus before it is born. Id., at 409; see also Carhart,
supra, at 862, 878. Another doctor testified he crushes a
fetus’ skull not only to reduce its size but also to ensure
the fetus is dead before it is removed. For the staff to have
to deal with a fetus that has “some viability to it, some
movement of limbs,” according to this doctor, “[is] always a
difficult situation.” App. in No. 05–380, at 94; see
Carhart, supra, at 858.
D&E and intact D&E are not the only second-trimester
abortion methods. Doctors also may abort a fetus through
medical induction. The doctor medicates the woman to
induce labor, and contractions occur to deliver the fetus.
Induction, which unlike D&E should occur in a hospital,
can last as little as 6 hours but can take longer than 48. It
accounts for about five percent of second-trimester abor
tions before 20 weeks of gestation and 15 percent of those
after 20 weeks. Doctors turn to two other methods of
second-trimester abortion, hysterotomy and hysterectomy,
only in emergency situations because they carry increased
risk of complications. In a hysterotomy, as in a cesarean
section, the doctor removes the fetus by making an inci
sion through the abdomen and uterine wall to gain access
to the uterine cavity. A hysterectomy requires the re
moval of the entire uterus. These two procedures repre
sent about .07% of second-trimester abortions. Nat. Abor
tion Federation, 330 F. Supp. 2d, at 467; Planned
Parenthood, supra, at 962–963.
10 GONZALES v. CARHART
Opinion of the Court
B
After Dr. Haskell’s procedure received public attention,
with ensuing and increasing public concern, bans on “ ‘par
tial birth abortion’ ” proliferated. By the time of the Sten
berg decision, about 30 States had enacted bans designed
to prohibit the procedure. 530 U. S., at 995–996, and nn.
12–13 (THOMAS, J., dissenting); see also H. R. Rep. No.
108–58, at 4–5. In 1996, Congress also acted to ban par
tial-birth abortion. President Clinton vetoed the congres
sional legislation, and the Senate failed to override the
veto. Congress approved another bill banning the proce
dure in 1997, but President Clinton again vetoed it. In
2003, after this Court’s decision in Stenberg, Congress
passed the Act at issue here. H. R. Rep. No. 108–58, at
12–14. On November 5, 2003, President Bush signed the
Act into law. It was to take effect the following day. 18
U. S. C. §1531(a) (2000 ed., Supp. IV).
The Act responded to Stenberg in two ways. First,
Congress made factual findings. Congress determined
that this Court in Stenberg “was required to accept the
very questionable findings issued by the district court
judge,” §2(7), 117 Stat. 1202, notes following 18 U. S. C.
§1531 (2000 ed., Supp. IV), p. 768, ¶(7) (Congressional
Findings), but that Congress was “not bound to accept the
same factual findings,” ibid., ¶(8). Congress found, among
other things, that “[a] moral, medical, and ethical consen
sus exists that the practice of performing a partial-birth
abortion . . . is a gruesome and inhumane procedure that
is never medically necessary and should be prohibited.”
Id., at 767, ¶(1).
Second, and more relevant here, the Act’s language
differs from that of the Nebraska statute struck down in
Stenberg. See 530 U. S., at 921–922 (quoting Neb. Rev.
Stat. Ann. §§28–328(1), 28–326(9) (Supp. 1999)). The
operative provisions of the Act provide in relevant part:
Cite as: 550 U. S. ____ (2007) 11
Opinion of the Court
“(a) Any physician who, in or affecting interstate or
foreign commerce, knowingly performs a partial-birth
abortion and thereby kills a human fetus shall be
fined under this title or imprisoned not more than 2
years, or both. This subsection does not apply to a
partial-birth abortion that is necessary to save the life
of a mother whose life is endangered by a physical
disorder, physical illness, or physical injury, including
a life-endangering physical condition caused by or
arising from the pregnancy itself. This subsection
takes effect 1 day after the enactment.
“(b) As used in this section—
“(1) the term ‘partial-birth abortion’ means an abor
tion in which the person performing the abortion—
“(A) deliberately and intentionally vaginally delivers
a living fetus until, in the case of a head-first presen
tation, the entire fetal head is outside the body of the
mother, or, in the case of breech presentation, any
part of the fetal trunk past the navel is outside the
body of the mother, for the purpose of performing an
overt act that the person knows will kill the partially
delivered living fetus; and
“(B) performs the overt act, other than completion of
delivery, that kills the partially delivered living fetus;
and
“(2) the term ‘physician’ means a doctor of medicine
or osteopathy legally authorized to practice medicine
and surgery by the State in which the doctor performs
such activity, or any other individual legally author
ized by the State to perform abortions: Provided, how
ever, That any individual who is not a physician or not
otherwise legally authorized by the State to perform
abortions, but who nevertheless directly performs a
partial-birth abortion, shall be subject to the provi
sions of this section.
. . . . .
12 GONZALES v. CARHART
Opinion of the Court
“(d)(1) A defendant accused of an offense under this
section may seek a hearing before the State Medical
Board on whether the physician’s conduct was neces
sary to save the life of the mother whose life was en
dangered by a physical disorder, physical illness, or
physical injury, including a life-endangering physical
condition caused by or arising from the pregnancy
itself.
“(2) The findings on that issue are admissible on that
issue at the trial of the defendant. Upon a motion of
the defendant, the court shall delay the beginning of
the trial for not more than 30 days to permit such a
hearing to take place.
“(e) A woman upon whom a partial-birth abortion is
performed may not be prosecuted under this section,
for a conspiracy to violate this section, or for an of
fense under section 2, 3, or 4 of this title based on a
violation of this section.” 18 U. S. C. §1531 (2000 ed.,
Supp. IV).
The Act also includes a provision authorizing civil actions
that is not of relevance here. §1531(c).
C
The District Court in Carhart concluded the Act was
unconstitutional for two reasons. First, it determined the
Act was unconstitutional because it lacked an exception
allowing the procedure where necessary for the health of
the mother. 331 F. Supp. 2d, at 1004–1030. Second, the
District Court found the Act deficient because it covered
not merely intact D&E but also certain other D&Es. Id.,
at 1030–1037.
The Court of Appeals for the Eighth Circuit addressed
only the lack of a health exception. 413 F. 3d, at 803–804.
The court began its analysis with what it saw as the ap
propriate question—“whether ‘substantial medical author
ity’ supports the medical necessity of the banned proce
Cite as: 550 U. S. ____ (2007) 13
Opinion of the Court
dure.” Id., at 796 (quoting Stenberg, 530 U. S., at 938).
This was the proper framework, according to the Court of
Appeals, because “when a lack of consensus exists in the
medical community, the Constitution requires legislatures
to err on the side of protecting women’s health by includ
ing a health exception.” 413 F. 3d, at 796. The court
rejected the Attorney General’s attempt to demonstrate
changed evidentiary circumstances since Stenberg and
considered itself bound by Stenberg’s conclusion that a
health exception was required. 413 F. 3d, at 803 (explain
ing “[t]he record in [the] case and the record in Stenberg
[were] similar in all significant respects”). It invalidated
the Act. Ibid.
D
The District Court in Planned Parenthood concluded the
Act was unconstitutional “because it (1) pose[d] an undue
burden on a woman’s ability to choose a second trimester
abortion; (2) [was] unconstitutionally vague; and (3) re
quire[d] a health exception as set forth by . . . Stenberg.”
320 F. Supp. 2d, at 1034–1035.
The Court of Appeals for the Ninth Circuit agreed. Like
the Court of Appeals for the Eighth Circuit, it concluded
the absence of a health exception rendered the Act uncon
stitutional. The court interpreted Stenberg to require a
health exception unless “there is consensus in the medical
community that the banned procedure is never medically
necessary to preserve the health of women.” 435 F. 3d, at
1173. Even after applying a deferential standard of re
view to Congress’ factual findings, the Court of Appeals
determined “substantial disagreement exists in the medi
cal community regarding whether” the procedures prohib
ited by the Act are ever necessary to preserve a woman’s
health. Id., at 1175–1176.
The Court of Appeals concluded further that the Act
placed an undue burden on a woman’s ability to obtain a
14 GONZALES v. CARHART
Opinion of the Court
second-trimester abortion. The court found the textual
differences between the Act and the Nebraska statute
struck down in Stenberg insufficient to distinguish D&E
and intact D&E. 435 F. 3d, at 1178–1180. As a result,
according to the Court of Appeals, the Act imposed an
undue burden because it prohibited D&E. Id., at 1180–
1181.
Finally, the Court of Appeals found the Act void for
vagueness. Id., at 1181. Abortion doctors testified they
were uncertain which procedures the Act made criminal.
The court thus concluded the Act did not offer physicians
clear warning of its regulatory reach. Id., at 1181–1184.
Resting on its understanding of the remedial framework
established by this Court in Ayotte v. Planned Parenthood
of Northern New Eng., 546 U. S. 320, 328–330 (2006), the
Court of Appeals held the Act was unconstitutional on its
face and should be permanently enjoined. 435 F. 3d, at
1184–1191.
II
The principles set forth in the joint opinion in Planned
Parenthood of Southeastern Pa. v. Casey, 505 U. S. 833
(1992), did not find support from all those who join the
instant opinion. See id., at 979–1002 (SCALIA, J., joined
by THOMAS, J., inter alios, concurring in judgment in part
and dissenting in part). Whatever one’s views concerning
the Casey joint opinion, it is evident a premise central to
its conclusion—that the government has a legitimate and
substantial interest in preserving and promoting fetal
life—would be repudiated were the Court now to affirm
the judgments of the Courts of Appeals.
Casey involved a challenge to Roe v. Wade, 410 U. S. 113
(1973). The opinion contains this summary:
“It must be stated at the outset and with clarity
that Roe’s essential holding, the holding we reaffirm,
has three parts. First is a recognition of the right of
Cite as: 550 U. S. ____ (2007) 15
Opinion of the Court
the woman to choose to have an abortion before viabil
ity and to obtain it without undue interference from
the State. Before viability, the State’s interests are
not strong enough to support a prohibition of abortion
or the imposition of a substantial obstacle to the
woman’s effective right to elect the procedure. Second
is a confirmation of the State’s power to restrict abor
tions after fetal viability, if the law contains excep
tions for pregnancies which endanger the woman’s life
or health. And third is the principle that the State
has legitimate interests from the outset of the preg
nancy in protecting the health of the woman and the
life of the fetus that may become a child. These prin
ciples do not contradict one another; and we adhere to
each.” 505 U. S., at 846 (opinion of the Court).
Though all three holdings are implicated in the instant
cases, it is the third that requires the most extended
discussion; for we must determine whether the Act fur
thers the legitimate interest of the Government in protect
ing the life of the fetus that may become a child.
To implement its holding, Casey rejected both Roe’s rigid
trimester framework and the interpretation of Roe that
considered all previability regulations of abortion unwar
ranted. 505 U. S., at 875–876, 878 (plurality opinion). On
this point Casey overruled the holdings in two cases be
cause they undervalued the State’s interest in potential
life. See id., at 881–883 (joint opinion) (overruling Thorn-
burgh v. American College of Obstetricians and Gynecolo
gists, 476 U. S. 747 (1986) and Akron v. Akron Center for
Reproductive Health, Inc., 462 U. S. 416 (1983)).
We assume the following principles for the purposes of
this opinion. Before viability, a State “may not prohibit
any woman from making the ultimate decision to termi
nate her pregnancy.” 505 U. S., at 879 (plurality opinion).
It also may not impose upon this right an undue burden,
16 GONZALES v. CARHART
Opinion of the Court
which exists if a regulation’s “purpose or effect is to place
a substantial obstacle in the path of a woman seeking an
abortion before the fetus attains viability.” Id., at 878. On
the other hand, “[r]egulations which do no more than
create a structural mechanism by which the State, or the
parent or guardian of a minor, may express profound
respect for the life of the unborn are permitted, if they are
not a substantial obstacle to the woman’s exercise of the
right to choose.” Id., at 877. Casey, in short, struck a
balance. The balance was central to its holding. We now
apply its standard to the cases at bar.
III
We begin with a determination of the Act’s operation
and effect. A straightforward reading of the Act’s text
demonstrates its purpose and the scope of its provisions: It
regulates and proscribes, with exceptions or qualifications
to be discussed, performing the intact D&E procedure.
Respondents agree the Act encompasses intact D&E,
but they contend its additional reach is both unclear and
excessive. Respondents assert that, at the least, the Act is
void for vagueness because its scope is indefinite. In the
alternative, respondents argue the Act’s text proscribes all
D&Es. Because D&E is the most common second-
trimester abortion method, respondents suggest the Act
imposes an undue burden. In this litigation the Attorney
General does not dispute that the Act would impose an
undue burden if it covered standard D&E.
We conclude that the Act is not void for vagueness, does
not impose an undue burden from any overbreadth, and is
not invalid on its face.
A
The Act punishes “knowingly perform[ing]” a “partial
birth abortion.” §1531(a) (2000 ed., Supp. IV). It defines
the unlawful abortion in explicit terms. §1531(b)(1).
Cite as: 550 U. S. ____ (2007) 17
Opinion of the Court
First, the person performing the abortion must “vagi
nally delive[r] a living fetus.” §1531(b)(1)(A). The Act
does not restrict an abortion procedure involving the
delivery of an expired fetus. The Act, furthermore, is
inapplicable to abortions that do not involve vaginal deliv
ery (for instance, hysterotomy or hysterectomy). The Act
does apply both previability and postviability because, by
common understanding and scientific terminology, a fetus
is a living organism while within the womb, whether or
not it is viable outside the womb. See, e.g., Planned Par
enthood, 320 F. Supp. 2d, at 971–972. We do not under
stand this point to be contested by the parties.
Second, the Act’s definition of partial-birth abortion
requires the fetus to be delivered “until, in the case of a
head-first presentation, the entire fetal head is outside the
body of the mother, or, in the case of breech presentation,
any part of the fetal trunk past the navel is outside the
body of the mother.” §1531(b)(1)(A) (2000 ed., Supp. IV).
The Attorney General concedes, and we agree, that if an
abortion procedure does not involve the delivery of a living
fetus to one of these “anatomical ‘landmarks’ ”—where,
depending on the presentation, either the fetal head or the
fetal trunk past the navel is outside the body of the
mother—the prohibitions of the Act do not apply. Brief for
Petitioner in No. 05–380, p. 46.
Third, to fall within the Act, a doctor must perform an
“overt act, other than completion of delivery, that kills the
partially delivered living fetus.” §1531(b)(1)(B) (2000 ed.,
Supp. IV). For purposes of criminal liability, the overt act
causing the fetus’ death must be separate from delivery.
And the overt act must occur after the delivery to an
anatomical landmark. This is because the Act proscribes
killing “the partially delivered” fetus, which, when read in
context, refers to a fetus that has been delivered to an
anatomical landmark. Ibid.
Fourth, the Act contains scienter requirements concern
18 GONZALES v. CARHART
Opinion of the Court
ing all the actions involved in the prohibited abortion. To
begin with, the physician must have “deliberately and
intentionally” delivered the fetus to one of the Act’s ana
tomical landmarks. §1531(b)(1)(A). If a living fetus is
delivered past the critical point by accident or inadver
tence, the Act is inapplicable. In addition, the fetus must
have been delivered “for the purpose of performing an
overt act that the [doctor] knows will kill [it].” Ibid. If
either intent is absent, no crime has occurred. This fol
lows from the general principle that where scienter is
required no crime is committed absent the requisite state
of mind. See generally 1 W. LaFave, Substantive Crimi
nal Law §5.1 (2d ed. 2003) (hereinafter LaFave); 1 C.
Torcia, Wharton’s Criminal Law §27 (15th ed. 1993).
B
Respondents contend the language described above is
indeterminate, and they thus argue the Act is unconstitu
tionally vague on its face. “As generally stated, the void-
for-vagueness doctrine requires that a penal statute define
the criminal offense with sufficient definiteness that ordi
nary people can understand what conduct is prohibited
and in a manner that does not encourage arbitrary and
discriminatory enforcement.” Kolender v. Lawson, 461
U. S. 352, 357 (1983); Posters ‘N’ Things, Ltd. v. United
States, 511 U. S. 513, 525 (1994). The Act satisfies both
requirements.
The Act provides doctors “of ordinary intelligence a
reasonable opportunity to know what is prohibited.”
Grayned v. City of Rockford, 408 U. S. 104, 108 (1972).
Indeed, it sets forth “relatively clear guidelines as to pro
hibited conduct” and provides “objective criteria” to evalu
ate whether a doctor has performed a prohibited proce
dure. Posters ‘N’ Things, supra, at 525–526. Unlike the
statutory language in Stenberg that prohibited the deliv
ery of a “ ‘substantial portion’ ” of the fetus—where a doc
Cite as: 550 U. S. ____ (2007) 19
Opinion of the Court
tor might question how much of the fetus is a substantial
portion—the Act defines the line between potentially
criminal conduct on the one hand and lawful abortion on
the other. Stenberg, 530 U. S., at 922 (quoting Neb. Rev.
Stat. Ann. §28–326(9) (Supp. 1999)). Doctors performing
D&E will know that if they do not deliver a living fetus
to an anatomical landmark they will not face criminal
liability.
This conclusion is buttressed by the intent that must be
proved to impose liability. The Court has made clear that
scienter requirements alleviate vagueness concerns.
Posters ‘N’ Things, supra, at 526; see also Colautti v.
Franklin, 439 U. S. 379, 395 (1979) (“This Court has long
recognized that the constitutionality of a vague statutory
standard is closely related to whether that standard in
corporates a requirement of mens rea”). The Act requires
the doctor deliberately to have delivered the fetus to an
anatomical landmark. §1531(b)(1)(A) (2000 ed., Supp. IV).
Because a doctor performing a D&E will not face criminal
liability if he or she delivers a fetus beyond the prohibited
point by mistake, the Act cannot be described as “a trap
for those who act in good faith.” Colautti, supra, at 395
(internal quotation marks omitted).
Respondents likewise have failed to show that the Act
should be invalidated on its face because it encourages
arbitrary or discriminatory enforcement. Kolender, supra,
at 357. Just as the Act’s anatomical landmarks provide
doctors with objective standards, they also “establish
minimal guidelines to govern law enforcement.” Smith v.
Goguen, 415 U. S. 566, 574 (1974). The scienter require
ments narrow the scope of the Act’s prohibition and limit
prosecutorial discretion. It cannot be said that the Act
“vests virtually complete discretion in the hands of [law
enforcement] to determine whether the [doctor] has satis
fied [its provisions].” Kolender, supra, at 358 (invalidating
a statute regulating loitering). Respondents’ arguments
20 GONZALES v. CARHART
Opinion of the Court
concerning arbitrary enforcement, furthermore, are some
what speculative. This is a preenforcement challenge,
where “no evidence has been, or could be, introduced to
indicate whether the [Act] has been enforced in a dis
criminatory manner or with the aim of inhibiting [consti
tutionally protected conduct].” Hoffman Estates v. Flip-
side, Hoffman Estates, Inc., 455 U. S. 489, 503 (1982). The
Act is not vague.
C
We next determine whether the Act imposes an undue
burden, as a facial matter, because its restrictions on
second-trimester abortions are too broad. A review of the
statutory text discloses the limits of its reach. The Act
prohibits intact D&E; and, notwithstanding respondents’
arguments, it does not prohibit the D&E procedure in
which the fetus is removed in parts.
1
The Act prohibits a doctor from intentionally performing
an intact D&E. The dual prohibitions of the Act, both of
which are necessary for criminal liability, correspond with
the steps generally undertaken during this type of proce
dure. First, a doctor delivers the fetus until its head
lodges in the cervix, which is usually past the anatomical
landmark for a breech presentation. See 18 U. S. C.
§1531(b)(1)(A) (2000 ed., Supp. IV). Second, the doctor
proceeds to pierce the fetal skull with scissors or crush it
with forceps. This step satisfies the overt-act requirement
because it kills the fetus and is distinct from delivery. See
§1531(b)(1)(B). The Act’s intent requirements, however,
limit its reach to those physicians who carry out the intact
D&E after intending to undertake both steps at the outset.
The Act excludes most D&Es in which the fetus is re
moved in pieces, not intact. If the doctor intends to re
move the fetus in parts from the outset, the doctor will not

have the requisite intent to incur criminal liability. A
doctor performing a standard D&E procedure can often
“tak[e] about 10–15 ‘passes’ through the uterus to remove
the entire fetus.” Planned Parenthood, 320 F. Supp. 2d, at
962. Removing the fetus in this manner does not violate
the Act because the doctor will not have delivered the
living fetus to one of the anatomical landmarks or commit
ted an additional overt act that kills the fetus after partial
delivery. §1531(b)(1) (2000 ed., Supp. IV).
A comparison of the Act with the Nebraska statute
struck down in Stenberg confirms this point. The statute
in Stenberg prohibited “ ‘deliberately and intentionally
delivering into the vagina a living unborn child, or a sub
stantial portion thereof, for the purpose of performing a
procedure that the person performing such procedure
knows will kill the unborn child and does kill the unborn
child.’ ” 530 U. S., at 922 (quoting Neb. Rev. Stat. Ann.
§28–326(9) (Supp. 1999)). The Court concluded that this
statute encompassed D&E because “D&E will often in
volve a physician pulling a ‘substantial portion’ of a still
living fetus, say, an arm or leg, into the vagina prior to the
death of the fetus.” 530 U. S., at 939. The Court also
rejected the limiting interpretation urged by Nebraska’s
Attorney General that the statute’s reference to a “proce
dure” that “ ‘kill[s] the unborn child’ ” was to a distinct
procedure, not to the abortion procedure as a whole. Id.,
at 943.
Congress, it is apparent, responded to these concerns
because the Act departs in material ways from the statute
in Stenberg. It adopts the phrase “delivers a living fetus,”
§1531(b)(1)(A) (2000 ed., Supp. IV), instead of “ ‘delivering
. . . a living unborn child, or a substantial portion
thereof,’ ” 530 U. S., at 938 (quoting Neb. Rev. Stat. Ann.
§28–326(9) (Supp. 1999)). The Act’s language, unlike the
statute in Stenberg, expresses the usual meaning of “de
liver” when used in connection with “fetus,” namely, ex
22 GONZALES v. CARHART
Opinion of the Court
traction of an entire fetus rather than removal of fetal
pieces. See Stedman’s Medical Dictionary 470 (27th ed.
2000) (defining deliver as “[t]o assist a woman in child
birth” and “[t]o extract from an enclosed place, as the fetus
from the womb, an object or foreign body”); see also I. Dox,
B. Melloni, G. Eisner, & J. Melloni, The HarperCollins
Illustrated Medical Dictionary 160 (4th ed. 2001); Mer
riam Webster’s Collegiate Dictionary 306 (10th ed. 1997).
The Act thus displaces the interpretation of “delivering”
dictated by the Nebraska statute’s reference to a “substan
tial portion” of the fetus. Stenberg, supra, at 944 (indicat
ing that the Nebraska “statute itself specifies that it ap
plies both to delivering ‘an intact unborn child’ or ‘a
substantial portion thereof’ ”). In interpreting statutory
texts courts use the ordinary meaning of terms unless
context requires a different result. See, e.g., 2A N. Singer,
Sutherland on Statutes and Statutory Construction §47:28
(rev. 6th ed. 2000). Here, unlike in Stenberg, the language
does not require a departure from the ordinary meaning.
D&E does not involve the delivery of a fetus because it
requires the removal of fetal parts that are ripped from
the fetus as they are pulled through the cervix.
The identification of specific anatomical landmarks to
which the fetus must be partially delivered also differenti
ates the Act from the statute at issue in Stenberg.
§1531(b)(1)(A) (2000 ed., Supp. IV). The Court in Stenberg
interpreted “ ‘substantial portion’ ” of the fetus to include
an arm or a leg. 530 U. S., at 939. The Act’s anatomical
landmarks, by contrast, clarify that the removal of a small
portion of the fetus is not prohibited. The landmarks also
require the fetus to be delivered so that it is partially
“outside the body of the mother.” §1531(b)(1)(A). To come
within the ambit of the Nebraska statute, on the other
hand, a substantial portion of the fetus only had to be
delivered into the vagina; no part of the fetus had to be
outside the body of the mother before a doctor could face
Cite as: 550 U. S. ____ (2007) 23
Opinion of the Court
criminal sanctions. Id., at 938–939.
By adding an overt-act requirement Congress sought
further to meet the Court’s objections to the state statute
considered in Stenberg. Compare 18 U. S. C. §1531(b)(1)
(2000 ed., Supp. IV) with Neb. Rev. Stat. Ann. §28–326(9)
(Supp. 1999). The Act makes the distinction the Nebraska
statute failed to draw (but the Nebraska Attorney General
advanced) by differentiating between the overall partial-
birth abortion and the distinct overt act that kills the
fetus. See Stenberg, 530 U. S., at 943–944. The fatal
overt act must occur after delivery to an anatomical land
mark, and it must be something “other than [the] comple
tion of delivery.” §1531(b)(1)(B). This distinction matters
because, unlike intact D&E, standard D&E does not in
volve a delivery followed by a fatal act.
The canon of constitutional avoidance, finally, extin
guishes any lingering doubt as to whether the Act covers
the prototypical D&E procedure. “ ‘[T]he elementary rule
is that every reasonable construction must be resorted to,
in order to save a statute from unconstitutionality.’ ”
Edward J. DeBartolo Corp. v. Florida Gulf Coast Building
& Constr. Trades Council, 485 U. S. 568, 575 (1988) (quot
ing Hooper v. California, 155 U. S. 648, 657 (1895)). It is
true this longstanding maxim of statutory interpretation
has, in the past, fallen by the wayside when the Court
confronted a statute regulating abortion. The Court at
times employed an antagonistic “ ‘canon of construction
under which in cases involving abortion, a permissible
reading of a statute [was] to be avoided at all costs.’ ”
Stenberg, supra, at 977 (KENNEDY, J., dissenting) (quoting
Thornburgh, 476 U. S., at 829 (O’Connor, J., dissenting)).
Casey put this novel statutory approach to rest. Stenberg,
supra, at 977 (KENNEDY, J., dissenting). Stenberg need
not be interpreted to have revived it. We read that deci
sion instead to stand for the uncontroversial proposition
that the canon of constitutional avoidance does not apply
24 GONZALES v. CARHART
Opinion of the Court
if a statute is not “genuinely susceptible to two construc
tions.” Almendarez-Torres v. United States, 523 U. S. 224,
238 (1998); see also Clark v. Martinez, 543 U. S. 371, 385
(2005). In Stenberg the Court found the statute covered
D&E. 530 U. S., at 938–945. Here, by contrast, interpret
ing the Act so that it does not prohibit standard D&E is
the most reasonable reading and understanding of its
terms.
2
Contrary arguments by the respondents are unavailing.
Respondents look to situations that might arise during
D&E, situations not examined in Stenberg. They con
tend—relying on the testimony of numerous abortion
doctors—that D&E may result in the delivery of a living
fetus beyond the Act’s anatomical landmarks in a signifi
cant fraction of cases. This is so, respondents say, because
doctors cannot predict the amount the cervix will dilate
before the abortion procedure. It might dilate to a degree
that the fetus will be removed largely intact. To complete
the abortion, doctors will commit an overt act that kills
the partially delivered fetus. Respondents thus posit that
any D&E has the potential to violate the Act, and that a
physician will not know beforehand whether the abortion
will proceed in a prohibited manner. Brief for Respondent
Planned Parenthood et al. in No. 05–1382, p. 38.
This reasoning, however, does not take account of the
Act’s intent requirements, which preclude liability from
attaching to an accidental intact D&E. If a doctor’s intent
at the outset is to perform a D&E in which the fetus would
not be delivered to either of the Act’s anatomical land
marks, but the fetus nonetheless is delivered past one of
those points, the requisite and prohibited scienter is not
present. 18 U. S. C. §1531(b)(1)(A) (2000 ed., Supp. IV).
When a doctor in that situation completes an abortion by
performing an intact D&E, the doctor does not violate the
Cite as: 550 U. S. ____ (2007) 25
Opinion of the Court
Act. It is true that intent to cause a result may sometimes
be inferred if a person “knows that that result is practi
cally certain to follow from his conduct.” 1 LaFave §5.2(a),
at 341. Yet abortion doctors intending at the outset to
perform a standard D&E procedure will not know that a
prohibited abortion “is practically certain to follow from”
their conduct. Ibid. A fetus is only delivered largely
intact in a small fraction of the overall number of D&E
abortions. Planned Parenthood, 320 F. Supp. 2d, at 965.
The evidence also supports a legislative determination
that an intact delivery is almost always a conscious choice
rather than a happenstance. Doctors, for example, may
remove the fetus in a manner that will increase the
chances of an intact delivery. See, e.g., App. in No. 05–
1382, at 74, 452. And intact D&E is usually described as
involving some manner of serial dilation. See, e.g., Dila
tion and Extraction 110. Doctors who do not seek to ob
tain this serial dilation perform an intact D&E on far
fewer occasions. See, e.g., Carhart, 331 F. Supp. 2d, at
857–858 (“In order for intact removal to occur on a regular
basis, Dr. Fitzhugh would have to dilate his patients with
a second round of laminaria”). This evidence belies any
claim that a standard D&E cannot be performed without
intending or foreseeing an intact D&E.
Many doctors who testified on behalf of respondents,
and who objected to the Act, do not perform an intact D&E
by accident. On the contrary, they begin every D&E abor
tion with the objective of removing the fetus as intact as
possible. See, e.g., id., at 869 (“Since Dr. Chasen believes
that the intact D & E is safer than the dismemberment D
& E, Dr. Chasen’s goal is to perform an intact D & E every
time”); see also id., at 873, 886. This does not prove, as
respondents suggest, that every D&E might violate the
Act and that the Act therefore imposes an undue burden.
It demonstrates only that those doctors who intend to
perform a D&E that would involve delivery of a living
26 GONZALES v. CARHART
Opinion of the Court
fetus to one of the Act’s anatomical landmarks must adjust
their conduct to the law by not attempting to deliver the
fetus to either of those points. Respondents have not
shown that requiring doctors to intend dismemberment
before delivery to an anatomical landmark will prohibit
the vast majority of D&E abortions. The Act, then, cannot
be held invalid on its face on these grounds.
IV
Under the principles accepted as controlling here, the
Act, as we have interpreted it, would be unconstitutional
“if its purpose or effect is to place a substantial obstacle in
the path of a woman seeking an abortion before the fetus
attains viability.” Casey, 505 U. S., at 878 (plurality opin
ion). The abortions affected by the Act’s regulations take
place both previability and postviability; so the quoted
language and the undue burden analysis it relies upon are
applicable. The question is whether the Act, measured by
its text in this facial attack, imposes a substantial obstacle
to late-term, but previability, abortions. The Act does not
on its face impose a substantial obstacle, and we reject
this further facial challenge to its validity.
A
The Act’s purposes are set forth in recitals preceding its
operative provisions. A description of the prohibited abor
tion procedure demonstrates the rationale for the congres
sional enactment. The Act proscribes a method of abortion
in which a fetus is killed just inches before completion of
the birth process. Congress stated as follows: “Implicitly
approving such a brutal and inhumane procedure by
choosing not to prohibit it will further coarsen society to
the humanity of not only newborns, but all vulnerable and
innocent human life, making it increasingly difficult to
protect such life.” Congressional Findings (14)(N), in
notes following 18 U. S. C. §1531 (2000 ed., Supp. IV), p.
Cite as: 550 U. S. ____ (2007) 27
Opinion of the Court
769. The Act expresses respect for the dignity of human
life.
Congress was concerned, furthermore, with the effects
on the medical community and on its reputation caused by
the practice of partial-birth abortion. The findings in the
Act explain:
“Partial-birth abortion . . . confuses the medical, legal,
and ethical duties of physicians to preserve and pro
mote life, as the physician acts directly against the
physical life of a child, whom he or she had just deliv
ered, all but the head, out of the womb, in order to end
that life.” Congressional Findings (14)(J), ibid.
There can be no doubt the government “has an interest in
protecting the integrity and ethics of the medical profes
sion.” Washington v. Glucksberg, 521 U. S. 702, 731
(1997); see also Barsky v. Board of Regents of Univ. of N.
Y., 347 U. S. 442, 451 (1954) (indicating the State has
“legitimate concern for maintaining high standards of
professional conduct” in the practice of medicine). Under
our precedents it is clear the State has a significant role to
play in regulating the medical profession.
Casey reaffirmed these governmental objectives. The
government may use its voice and its regulatory authority
to show its profound respect for the life within the woman.
A central premise of the opinion was that the Court’s
precedents after Roe had “undervalue[d] the State’s inter
est in potential life.” 505 U. S., at 873 (plurality opinion);
see also id., at 871. The plurality opinion indicated “[t]he
fact that a law which serves a valid purpose, one not
designed to strike at the right itself, has the incidental
effect of making it more difficult or more expensive to
procure an abortion cannot be enough to invalidate it.”
Id., at 874. This was not an idle assertion. The three
premises of Casey must coexist. See id., at 846 (opinion of
the Court). The third premise, that the State, from the
28 GONZALES v. CARHART
Opinion of the Court
inception of the pregnancy, maintains its own regulatory
interest in protecting the life of the fetus that may become
a child, cannot be set at naught by interpreting Casey’s
requirement of a health exception so it becomes tanta
mount to allowing a doctor to choose the abortion method
he or she might prefer. Where it has a rational basis to
act, and it does not impose an undue burden, the State
may use its regulatory power to bar certain procedures
and substitute others, all in furtherance of its legitimate
interests in regulating the medical profession in order to
promote respect for life, including life of the unborn.
The Act’s ban on abortions that involve partial delivery
of a living fetus furthers the Government’s objectives. No
one would dispute that, for many, D&E is a procedure
itself laden with the power to devalue human life. Con
gress could nonetheless conclude that the type of abortion
proscribed by the Act requires specific regulation because
it implicates additional ethical and moral concerns that
justify a special prohibition. Congress determined that
the abortion methods it proscribed had a “disturbing
similarity to the killing of a newborn infant,” Congres
sional Findings (14)(L), in notes following 18 U. S. C.
§1531 (2000 ed., Supp. IV), p. 769, and thus it was con
cerned with “draw[ing] a bright line that clearly distin
guishes abortion and infanticide.” Congressional Findings
(14)(G), ibid. The Court has in the past confirmed the
validity of drawing boundaries to prevent certain practices
that extinguish life and are close to actions that are con
demned. Glucksberg found reasonable the State’s “fear
that permitting assisted suicide will start it down the path
to voluntary and perhaps even involuntary euthanasia.”
521 U. S., at 732–735, and n. 23.
Respect for human life finds an ultimate expression in
the bond of love the mother has for her child. The Act
recognizes this reality as well. Whether to have an abor
tion requires a difficult and painful moral decision. Casey,
Cite as: 550 U. S. ____ (2007) 29
Opinion of the Court
supra, at 852–853 (opinion of the Court). While we find no
reliable data to measure the phenomenon, it seems unex
ceptionable to conclude some women come to regret their
choice to abort the infant life they once created and sus
tained. See Brief for Sandra Cano et al. as Amici Curiae
in No. 05–380, pp. 22–24. Severe depression and loss of
esteem can follow. See ibid.
In a decision so fraught with emotional consequence
some doctors may prefer not to disclose precise details of
the means that will be used, confining themselves to the
required statement of risks the procedure entails. From
one standpoint this ought not to be surprising. Any num
ber of patients facing imminent surgical procedures would
prefer not to hear all details, lest the usual anxiety preced
ing invasive medical procedures become the more intense.
This is likely the case with the abortion procedures here in
issue. See, e.g., Nat. Abortion Federation, 330 F. Supp. 2d,
at 466, n. 22 (“Most of [the plaintiffs’] experts acknowl
edged that they do not describe to their patients what [the
D&E and intact D&E] procedures entail in clear and
precise terms”); see also id., at 479.
It is, however, precisely this lack of information concern
ing the way in which the fetus will be killed that is of
legitimate concern to the State. Casey, supra, at 873
(plurality opinion) (“States are free to enact laws to pro
vide a reasonable framework for a woman to make a deci
sion that has such profound and lasting meaning”). The
State has an interest in ensuring so grave a choice is well
informed. It is self-evident that a mother who comes to
regret her choice to abort must struggle with grief more
anguished and sorrow more profound when she learns,
only after the event, what she once did not know: that she
allowed a doctor to pierce the skull and vacuum the fast-
developing brain of her unborn child, a child assuming the
human form.
It is a reasonable inference that a necessary effect of the
30 GONZALES v. CARHART
Opinion of the Court
regulation and the knowledge it conveys will be to encour
age some women to carry the infant to full term, thus
reducing the absolute number of late-term abortions. The
medical profession, furthermore, may find different and
less shocking methods to abort the fetus in the second
trimester, thereby accommodating legislative demand.
The State’s interest in respect for life is advanced by the
dialogue that better informs the political and legal sys
tems, the medical profession, expectant mothers, and
society as a whole of the consequences that follow from a
decision to elect a late-term abortion.
It is objected that the standard D&E is in some respects
as brutal, if not more, than the intact D&E, so that the
legislation accomplishes little. What we have already
said, however, shows ample justification for the regula
tion. Partial-birth abortion, as defined by the Act, differs
from a standard D&E because the former occurs when the
fetus is partially outside the mother to the point of one of
the Act’s anatomical landmarks. It was reasonable for
Congress to think that partial-birth abortion, more than
standard D&E, “undermines the public’s perception of the
appropriate role of a physician during the delivery process,
and perverts a process during which life is brought into
the world.” Congressional Findings (14)(K), in notes
following 18 U. S. C. §1531 (2000 ed., Supp. IV), p. 769.
There would be a flaw in this Court’s logic, and an irony in
its jurisprudence, were we first to conclude a ban on both
D&E and intact D&E was overbroad and then to say it is
irrational to ban only intact D&E because that does not
proscribe both procedures. In sum, we reject the conten
tion that the congressional purpose of the Act was “to
place a substantial obstacle in the path of a woman seek
ing an abortion.” 505 U. S., at 878 (plurality opinion).
B
The Act’s furtherance of legitimate government inter
Cite as: 550 U. S. ____ (2007) 31
Opinion of the Court
ests bears upon, but does not resolve, the next question:
whether the Act has the effect of imposing an unconstitu
tional burden on the abortion right because it does not
allow use of the barred procedure where “ ‘necessary, in
appropriate medical judgment, for [the] preservation of
the . . . health of the mother.’ ” Ayotte, 546 U. S., at 327–
328 (quoting Casey, supra, at 879 (plurality opinion)). The
prohibition in the Act would be unconstitutional, under
precedents we here assume to be controlling, if it “sub
ject[ed] [women] to significant health risks.” Ayotte, su
pra, at 328; see also Casey, supra, at 880 (opinion of the
Court). In Ayotte the parties agreed a health exception to
the challenged parental-involvement statute was neces
sary “to avert serious and often irreversible damage to [a
pregnant minor’s] health.” 546 U. S., at 328. Here, by
contrast, whether the Act creates significant health risks
for women has been a contested factual question. The
evidence presented in the trial courts and before Congress
demonstrates both sides have medical support for their
position.
Respondents presented evidence that intact D&E may
be the safest method of abortion, for reasons similar to
those adduced in Stenberg. See 530 U. S., at 932. Abor
tion doctors testified, for example, that intact D&E de
creases the risk of cervical laceration or uterine perfora
tion because it requires fewer passes into the uterus with
surgical instruments and does not require the removal of
bony fragments of the dismembered fetus, fragments that
may be sharp. Respondents also presented evidence that
intact D&E was safer both because it reduces the risks
that fetal parts will remain in the uterus and because it
takes less time to complete. Respondents, in addition,
proffered evidence that intact D&E was safer for women
with certain medical conditions or women with fetuses
that had certain anomalies. See, e.g., Carhart, 331
F. Supp. 2d, at 923–929; Nat. Abortion Federation, supra,
32 GONZALES v. CARHART
Opinion of the Court
at 470–474; Planned Parenthood, 320 F. Supp. 2d, at 982–
983.
These contentions were contradicted by other doctors
who testified in the District Courts and before Congress.
They concluded that the alleged health advantages were
based on speculation without scientific studies to support
them. They considered D&E always to be a safe alterna
tive. See, e.g., Carhart, supra, at 930–940; Nat. Abortion
Federation, 330 F. Supp. 2d, at 470–474; Planned Parent
hood, 320 F. Supp. 2d, at 983.
There is documented medical disagreement whether the
Act’s prohibition would ever impose significant health
risks on women. See, e.g., id., at 1033 (“[T]here continues
to be a division of opinion among highly qualified experts
regarding the necessity or safety of intact D & E”); see also
Nat. Abortion Federation, supra, at 482. The three Dis
trict Courts that considered the Act’s constitutionality
appeared to be in some disagreement on this central fac
tual question. The District Court for the District of Ne
braska concluded “the banned procedure is, sometimes,
the safest abortion procedure to preserve the health of
women.” Carhart, supra, at 1017. The District Court for
the Northern District of California reached a similar
conclusion. Planned Parenthood, supra, at 1002 (finding
intact D&E was “under certain circumstances . . . signifi
cantly safer than D & E by disarticulation”). The District
Court for the Southern District of New York was more
skeptical of the purported health benefits of intact D&E.
It found the Attorney General’s “expert witnesses rea
sonably and effectively refuted [the plaintiffs’] proffered
bases for the opinion that [intact D&E] has safety advan
tages over other second-trimester abortion procedures.”
Nat. Abortion Federation, 330 F. Supp. 2d, at 479. In
addition it did “not believe that many of [the plaintiffs’]
purported reasons for why [intact D&E] is medically nec
essary [were] credible; rather [it found them to be] theo
Cite as: 550 U. S. ____ (2007) 33
Opinion of the Court
retical or false.” Id., at 480. The court nonetheless invali
dated the Act because it determined “a significant body of
medical opinion . . . holds that D & E has safety advan
tages over induction and that [intact D&E] has some
safety advantages (however hypothetical and unsubstan
tiated by scientific evidence) over D & E for some women
in some circumstances.” Ibid.
The question becomes whether the Act can stand when
this medical uncertainty persists. The Court’s precedents
instruct that the Act can survive this facial attack. The
Court has given state and federal legislatures wide discre
tion to pass legislation in areas where there is medical and
scientific uncertainty. See Kansas v. Hendricks, 521 U. S.
346, 360, n. 3 (1997); Jones v. United States, 463 U. S. 354,
364–365, n. 13, 370 (1983); Lambert v. Yellowley, 272 U. S.
581, 597 (1926); Collins v. Texas, 223 U. S. 288, 297–298
(1912); Jacobson v. Massachusetts, 197 U. S. 11, 30–31
(1905); see also Stenberg, supra, at 969–972 (KENNEDY, J.,
dissenting); Marshall v. United States, 414 U. S. 417, 427
(1974) (“When Congress undertakes to act in areas fraught
with medical and scientific uncertainties, legislative op
tions must be especially broad”).
This traditional rule is consistent with Casey, which
confirms the State’s interest in promoting respect for
human life at all stages in the pregnancy. Physicians are
not entitled to ignore regulations that direct them to use
reasonable alternative procedures. The law need not give
abortion doctors unfettered choice in the course of their
medical practice, nor should it elevate their status above
other physicians in the medical community. In Casey the
controlling opinion held an informed-consent requirement
in the abortion context was “no different from a require
ment that a doctor give certain specific information about
any medical procedure.” 505 U. S., at 884 (joint opinion).
The opinion stated “the doctor-patient relation here is
entitled to the same solicitude it receives in other con
34 GONZALES v. CARHART
Opinion of the Court
texts.” Ibid.; see also Webster v. Reproductive Health
Services, 492 U. S. 490, 518–519 (1989) (plurality opinion)
(criticizing Roe’s trimester framework because, inter alia,
it “left this Court to serve as the country’s ex officio medi
cal board with powers to approve or disapprove medical
and operative practices and standards throughout the
United States” (internal quotation marks omitted));
Mazurek v. Armstrong, 520 U. S. 968, 973 (1997) (per
curiam) (upholding a restriction on the performance of
abortions to licensed physicians despite the respondents’
contention “all health evidence contradicts the claim that
there is any health basis for the law” (internal quotation
marks omitted)).
Medical uncertainty does not foreclose the exercise of
legislative power in the abortion context any more than it
does in other contexts. See Hendricks, supra, at 360, n. 3.
The medical uncertainty over whether the Act’s prohibi
tion creates significant health risks provides a sufficient
basis to conclude in this facial attack that the Act does not
impose an undue burden.
The conclusion that the Act does not impose an undue
burden is supported by other considerations. Alternatives
are available to the prohibited procedure. As we have
noted, the Act does not proscribe D&E. One District Court
found D&E to have extremely low rates of medical compli
cations. Planned Parenthood, supra, at 1000. Another
indicated D&E was “generally the safest method of abor
tion during the second trimester.” Carhart, 331 F. Supp.
2d, at 1031; see also Nat. Abortion Federation, supra, at
467–468 (explaining that “[e]xperts testifying for both
sides” agreed D&E was safe). In addition the Act’s prohi
bition only applies to the delivery of “a living fetus.” 18
U. S. C. §1531(b)(1)(A) (2000 ed., Supp. IV). If the intact
D&E procedure is truly necessary in some circumstances,
it appears likely an injection that kills the fetus is an
alternative under the Act that allows the doctor to perform
Cite as: 550 U. S. ____ (2007) 35
Opinion of the Court
the procedure.
The instant cases, then, are different from Planned
Parenthood of Central Mo. v. Danforth, 428 U. S. 52, 77–
79 (1976), in which the Court invalidated a ban on saline
amniocentesis, the then-dominant second-trimester abor
tion method. The Court found the ban in Danforth to be
“an unreasonable or arbitrary regulation designed to
inhibit, and having the effect of inhibiting, the vast major
ity of abortions after the first 12 weeks.” Id., at 79. Here
the Act allows, among other means, a commonly used and
generally accepted method, so it does not construct a
substantial obstacle to the abortion right.
In reaching the conclusion the Act does not require a
health exception we reject certain arguments made by the
parties on both sides of these cases. On the one hand, the
Attorney General urges us to uphold the Act on the basis
of the congressional findings alone. Brief for Petitioner in
No. 05–380, at 23. Although we review congressional
factfinding under a deferential standard, we do not in the
circumstances here place dispositive weight on Congress’
findings. The Court retains an independent constitutional
duty to review factual findings where constitutional rights
are at stake. See Crowell v. Benson, 285 U. S. 22, 60
(1932) (“In cases brought to enforce constitutional rights,
the judicial power of the United States necessarily extends
to the independent determination of all questions, both of
fact and law, necessary to the performance of that su
preme function”).
As respondents have noted, and the District Courts
recognized, some recitations in the Act are factually incor
rect. See Nat. Abortion Federation, 330 F. Supp. 2d, at
482, 488–491. Whether or not accurate at the time, some
of the important findings have been superseded. Two
examples suffice. Congress determined no medical schools
provide instruction on the prohibited procedure. Congres
sional Findings (14)(B), in notes following 18 U. S. C.
36 GONZALES v. CARHART
Opinion of the Court
§1531 (2000 ed., Supp. IV), p. 769. The testimony in the
District Courts, however, demonstrated intact D&E is
taught at medical schools. Nat. Abortion Federation,
supra, at 490; Planned Parenthood, 320 F. Supp. 2d, at
1029. Congress also found there existed a medical consen
sus that the prohibited procedure is never medically nec
essary. Congressional Findings (1), in notes following 18
U. S. C. §1531 (2000 ed., Supp. IV), p. 767. The evidence
presented in the District Courts contradicts that conclu
sion. See, e.g., Carhart, supra, at 1012–1015; Nat. Abor
tion Federation, supra, at 488–489; Planned Parenthood,
supra, at 1025–1026. Uncritical deference to Congress’
factual findings in these cases is inappropriate.
On the other hand, relying on the Court’s opinion in
Stenberg, respondents contend that an abortion regulation
must contain a health exception “if ‘substantial medical
authority supports the proposition that banning a particu
lar procedure could endanger women’s health.’ ” Brief for
Respondents in No. 05–380, p. 19 (quoting 530 U. S., at
938); see also Brief for Respondent Planned Parenthood
et al. in No. 05–1382, at 12 (same). As illustrated by
respondents’ arguments and the decisions of the Courts of
Appeals, Stenberg has been interpreted to leave no margin
of error for legislatures to act in the face of medical uncer
tainty. Carhart, 413 F. 3d, at 796; Planned Parenthood,
435 F. 3d, at 1173; see also Nat. Abortion Federation, 437
F. 3d, at 296 (Walker, C. J., concurring) (explaining the
standard under Stenberg “is a virtually insurmountable
evidentiary hurdle”).
A zero tolerance policy would strike down legitimate
abortion regulations, like the present one, if some part of
the medical community were disinclined to follow the
proscription. This is too exacting a standard to impose on
the legislative power, exercised in this instance under the
Commerce Clause, to regulate the medical profession.
Considerations of marginal safety, including the balance of
Cite as: 550 U. S. ____ (2007) 37
Opinion of the Court
risks, are within the legislative competence when the
regulation is rational and in pursuit of legitimate ends.
When standard medical options are available, mere con
venience does not suffice to displace them; and if some
procedures have different risks than others, it does not
follow that the State is altogether barred from imposing
reasonable regulations. The Act is not invalid on its face
where there is uncertainty over whether the barred proce
dure is ever necessary to preserve a woman’s health, given
the availability of other abortion procedures that are
considered to be safe alternatives.
V
The considerations we have discussed support our fur
ther determination that these facial attacks should not
have been entertained in the first instance. In these
circumstances the proper means to consider exceptions is
by as-applied challenge. The Government has acknowl
edged that preenforcement, as-applied challenges to the
Act can be maintained. Tr. of Oral Arg. in No. 05–380, pp.
21–23. This is the proper manner to protect the health of
the woman if it can be shown that in discrete and well-
defined instances a particular condition has or is likely to
occur in which the procedure prohibited by the Act must
be used. In an as-applied challenge the nature of the
medical risk can be better quantified and balanced than in
a facial attack.
The latitude given facial challenges in the First
Amendment context is inapplicable here. Broad chal
lenges of this type impose “a heavy burden” upon the
parties maintaining the suit. Rust v. Sullivan, 500 U. S.
173, 183 (1991). What that burden consists of in the
specific context of abortion statutes has been a subject of
some question. Compare Ohio v. Akron Center for Repro
ductive Health, 497 U. S. 502, 514 (1990) (“[B]ecause
appellees are making a facial challenge to a statute, they
38 GONZALES v. CARHART
Opinion of the Court
must show that no set of circumstances exists under which
the Act would be valid” (internal quotation marks omit
ted)), with Casey, 505 U. S., at 895 (opinion of the Court)
(indicating a spousal-notification statute would impose an
undue burden “in a large fraction of the cases in which [it]
is relevant” and holding the statutory provision facially
invalid). See also Janklow v. Planned Parenthood, Sioux
Falls Clinic, 517 U. S. 1174 (1996). We need not resolve
that debate.
As the previous sections of this opinion explain, respon
dents have not demonstrated that the Act would be uncon
stitutional in a large fraction of relevant cases. Casey,
supra, at 895 (opinion of the Court). We note that the
statute here applies to all instances in which the doctor
proposes to use the prohibited procedure, not merely those
in which the woman suffers from medical complications.
It is neither our obligation nor within our traditional
institutional role to resolve questions of constitutionality
with respect to each potential situation that might de
velop. “[I]t would indeed be undesirable for this Court to
consider every conceivable situation which might possibly
arise in the application of complex and comprehensive
legislation.” United States v. Raines, 362 U. S. 17, 21
(1960) (internal quotation marks omitted). For this rea
son, “[a]s-applied challenges are the basic building blocks
of constitutional adjudication.” Fallon, As-Applied and
Facial Challenges and Third-Party Standing, 113 Harv.
L. Rev. 1321, 1328 (2000).
The Act is open to a proper as-applied challenge in a
discrete case. Cf. Wisconsin Right to Life, Inc. v. Federal
Election Comm’n, 546 U. S. 410, 411–412 (2006) (per
curiam). No as-applied challenge need be brought if the
prohibition in the Act threatens a woman’s life because the
Act already contains a life exception. 18 U. S. C. §1531(a)
(2000 ed., Supp. IV).

Opinion of the Court
* * *
Respondents have not demonstrated that the Act, as a
facial matter, is void for vagueness, or that it imposes an
undue burden on a woman’s right to abortion based on its
overbreadth or lack of a health exception. For these rea
sons the judgments of the Courts of Appeals for the Eighth
and Ninth Circuits are reversed.

ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF
APPEALS FOR THE NINTH CIRCUIT
[April 18, 2007]
JUSTICE GINSBURG, with whom JUSTICE STEVENS,
JUSTICE SOUTER, and JUSTICE BREYER join, dissenting.
In Planned Parenthood of Southeastern Pa. v. Casey,
505 U. S. 833, 844 (1992), the Court declared that
“[l]iberty finds no refuge in a jurisprudence of doubt.”
There was, the Court said, an “imperative” need to dispel
doubt as to “the meaning and reach” of the Court’s 7-to-2
judgment, rendered nearly two decades earlier in Roe v.
Wade, 410 U. S. 113 (1973). 505 U. S., at 845. Responsive
to that need, the Court endeavored to provide secure
guidance to “[s]tate and federal courts as well as legisla
tures throughout the Union,” by defining “the rights of the
woman and the legitimate authority of the State respect
ing the termination of pregnancies by abortion proce

GINSBURG, J., dissenting
dures.” Ibid.
Taking care to speak plainly, the Casey Court restated
and reaffirmed Roe’s essential holding. 505 U. S., at 845–
846. First, the Court addressed the type of abortion regu
lation permissible prior to fetal viability. It recognized
“the right of the woman to choose to have an abortion
before viability and to obtain it without undue interfer
ence from the State.” Id., at 846. Second, the Court ac
knowledged “the State’s power to restrict abortions after
fetal viability, if the law contains exceptions for pregnan
cies which endanger the woman’s life or health.” Ibid.
(emphasis added). Third, the Court confirmed that “the
State has legitimate interests from the outset of the preg
nancy in protecting the health of the woman and the life of
the fetus that may become a child.” Ibid. (emphasis
added).
In reaffirming Roe, the Casey Court described the cen
trality of “the decision whether to bear . . . a child,” Eisen
stadt v. Baird, 405 U. S. 438, 453 (1972), to a woman’s
“dignity and autonomy,” her “personhood” and “destiny,”
her “conception of . . . her place in society.” 505 U. S., at
851–852. Of signal importance here, the Casey Court
stated with unmistakable clarity that state regulation of
access to abortion procedures, even after viability, must
protect “the health of the woman.” Id., at 846.
Seven years ago, in Stenberg v. Carhart, 530 U. S. 914
(2000), the Court invalidated a Nebraska statute criminal
izing the performance of a medical procedure that, in the
political arena, has been dubbed “partial-birth abortion.”1
——————
1 The term “partial-birth abortion” is neither recognized in the medi
cal literature nor used by physicians who perform second-trimester
abortions. See Planned Parenthood Federation of Am. v. Ashcroft, 320
F. Supp. 2d 957, 964 (ND Cal. 2004), aff’d, 435 F. 3d 1163 (CA9 2006).
The medical community refers to the procedure as either dilation &
extraction (D&X) or intact dilation and evacuation (intact D&E). See,
e.g., ante, at 5; Stenberg v. Carhart, 530 U. S. 914, 927 (2000).
Cite as: 550 U. S. ____ (2007) 3
GINSBURG, J., dissenting
With fidelity to the Roe-Casey line of precedent, the Court
held the Nebraska statute unconstitutional in part be
cause it lacked the requisite protection for the preserva
tion of a woman’s health. Stenberg, 530 U. S., at 930; cf.
Ayotte v. Planned Parenthood of Northern New Eng., 546
U. S. 320, 327 (2006).
Today’s decision is alarming. It refuses to take Casey
and Stenberg seriously. It tolerates, indeed applauds,
federal intervention to ban nationwide a procedure found
necessary and proper in certain cases by the American
College of Obstetricians and Gynecologists (ACOG). It
blurs the line, firmly drawn in Casey, between previability
and postviability abortions. And, for the first time since
Roe, the Court blesses a prohibition with no exception
safeguarding a woman’s health.
I dissent from the Court’s disposition. Retreating from
prior rulings that abortion restrictions cannot be imposed
absent an exception safeguarding a woman’s health, the
Court upholds an Act that surely would not survive under
the close scrutiny that previously attended state-decreed
limitations on a woman’s reproductive choices.

A
As Casey comprehended, at stake in cases challenging
abortion restrictions is a woman’s “control over her [own]
destiny.” 505 U. S., at 869 (plurality opinion). See also
id., at 852 (majority opinion).2 “There was a time, not so
long ago,” when women were “regarded as the center of
home and family life, with attendant special responsibili

2Planned Parenthood of Southeastern Pa. v. Casey, 505 U. S. 833,
851–852 (1992), described more precisely than did Roe v. Wade, 410
U. S. 113 (1973), the impact of abortion restrictions on women’s liberty.
Roe’s focus was in considerable measure on “vindicat[ing] the right of
the physician to administer medical treatment according to his profes
sional judgment.” Id., at 165.
4 GONZALES v. CARHART

ties that precluded full and independent legal status
under the Constitution.” Id., at 896–897 (quoting Hoyt v.
Florida, 368 U. S. 57, 62 (1961)). Those views, this Court
made clear in Casey, “are no longer consistent with our
understanding of the family, the individual, or the Consti
tution.” 505 U. S., at 897. Women, it is now acknowl
edged, have the talent, capacity, and right “to participate
equally in the economic and social life of the Nation.” Id.,
at 856. Their ability to realize their full potential, the
Court recognized, is intimately connected to “their ability
to control their reproductive lives.” Ibid. Thus, legal
challenges to undue restrictions on abortion procedures do
not seek to vindicate some generalized notion of privacy;
rather, they center on a woman’s autonomy to determine
her life’s course, and thus to enjoy equal citizenship stat
ure. See, e.g., Siegel, Reasoning from the Body: A Histori
cal Perspective on Abortion Regulation and Questions of
Equal Protection, 44 Stan. L. Rev. 261 (1992); Law, Re
thinking Sex and the Constitution, 132 U. Pa. L. Rev. 955,
1002–1028 (1984).
In keeping with this comprehension of the right to re
productive choice, the Court has consistently required that
laws regulating abortion, at any stage of pregnancy and in
all cases, safeguard a woman’s health. See, e.g., Ayotte,
546 U. S., at 327–328 (“[O]ur precedents hold . . . that a
State may not restrict access to abortions that are neces
sary, in appropriate medical judgment, for preservation of
the life or health of the [woman].” (quoting Casey, 505
U. S., at 879 (plurality opinion))); Stenberg, 530 U. S., at
930 (“Since the law requires a health exception in order to
validate even a postviability abortion regulation, it at a
minimum requires the same in respect to previability
regulation.”). See also Thornburgh v. American College of
Obstetricians and Gynecologists, 476 U. S. 747, 768–769
(1986) (invalidating a post-viability abortion regulation for
“fail[ure] to require that [a pregnant woman’s] health be

GINSBURG, J., dissenting
the physician’s paramount consideration”).
We have thus ruled that a State must avoid subjecting
women to health risks not only where the pregnancy itself
creates danger, but also where state regulation forces
women to resort to less safe methods of abortion. See
Planned Parenthood of Central Mo. v. Danforth, 428 U. S.
52, 79 (1976) (holding unconstitutional a ban on a method
of abortion that “force[d] a woman . . . to terminate her
pregnancy by methods more dangerous to her health”).
See also Stenberg, 530 U. S., at 931 (“[Our cases] make
clear that a risk to . . . women’s health is the same
whether it happens to arise from regulating a particular
method of abortion, or from barring abortion entirely.”).
Indeed, we have applied the rule that abortion regulation
must safeguard a woman’s health to the particular proce
dure at issue here—intact dilation and evacuation (D&E).3
——————
3 Dilation and evacuation (D&E) is the most frequently used abortion
procedure during the second trimester of pregnancy; intact D&E is a
variant of the D&E procedure. See ante, at 4, 6; Stenberg, 530 U. S., at
924, 927; Planned Parenthood, 320 F. Supp. 2d, at 966. Second-
trimester abortions (i.e., midpregnancy, previability abortions) are,
however, relatively uncommon. Between 85 and 90 percent of all
abortions performed in the United States take place during the first
three months of pregnancy. See ante, at 3. See also Stenberg, 530
U. S., at 923–927; National Abortion Federation v. Ashcroft, 330
F. Supp. 2d 436, 464 (SDNY 2004), aff’d sub nom. National Abortion
Federation v. Gonzales, 437 F. 3d 278 (CA2 2006); Planned Parenthood,
320 F. Supp. 2d, at 960, and n. 4.
Adolescents and indigent women, research suggests, are more likely
than other women to have difficulty obtaining an abortion during the
first trimester of pregnancy. Minors may be unaware they are preg
nant until relatively late in pregnancy, while poor women’s financial
constraints are an obstacle to timely receipt of services. See Finer,
Frohwirth, Dauphinee, Singh, & Moore, Timing of Steps and Reasons
for Delays in Obtaining Abortions in the United States, 74 Contracep
tion 334, 341–343 (2006). See also Drey et al., Risk Factors Associated
with Presenting for Abortion in the Second Trimester, 107 Obstetrics &

second-trimester abortions typically discover relatively late that they

GINSBURG, J., dissenting
In Stenberg, we expressly held that a statute banning
intact D&E was unconstitutional in part because it lacked
a health exception. 530 U. S., at 930, 937. We noted that
there existed a “division of medical opinion” about the
relative safety of intact D&E, id., at 937, but we made
clear that as long as “substantial medical authority sup
ports the proposition that banning a particular abortion
procedure could endanger women’s health,” a health ex
ception is required, id., at 938. We explained:
“The word ‘necessary’ in Casey’s phrase ‘necessary,
in appropriate medical judgment, for the preservation
of the life or health of the [pregnant woman],’ cannot
refer to an absolute necessity or to absolute proof.
Medical treatments and procedures are often consid
ered appropriate (or inappropriate) in light of esti
mated comparative health risks (and health benefits)
in particular cases. Neither can that phrase require
unanimity of medical opinion. Doctors often differ in
their estimation of comparative health risks and ap
propriate treatment. And Casey’s words ‘appropriate
medical judgment’ must embody the judicial need to
tolerate responsible differences of medical opinion

the pregnant woman are also causes of second-trimester abortions;
many such conditions cannot be diagnosed or do not develop until the
second trimester. See, e.g., Finer, supra, at 344; F. Cunningham et al.,
Williams Obstetrics 242, 290, 328–329, (22d ed. 2005); cf. Schechtman,

In 2003, a few years after our ruling in Stenberg, Con
gress passed the Partial-Birth Abortion Ban Act—without
an exception for women’s health. See 18 U. S. C. §1531(a)
(2000 ed., Supp. IV).4 The congressional findings on which
the Partial-Birth Abortion Ban Act rests do not withstand
inspection, as the lower courts have determined and this
Court is obliged to concede. Ante, at 35–36. See National

Many of the Act’s recitations are incorrect. See ante, at
35–36. For example, Congress determined that no medical
schools provide instruction on intact D&E. §2(14)(B), 117
Stat. 1204, notes following 18 U. S. C. §1531 (2000 ed.,
Supp. IV), p. 769, ¶(14)(B) (Congressional Findings). But
in fact, numerous leading medical schools teach the proce
dure. See Planned Parenthood, 320 F. Supp. 2d, at 1029;
National Abortion Federation, 330 F. Supp. 2d, at 479.
See also Brief for ACOG as Amicus Curiae 18 (“Among the
schools that now teach the intact variant are Columbia,
Cornell, Yale, New York University, Northwestern, Uni
versity of Pittsburgh, University of Pennsylvania, Univer
sity of Rochester, and University of Chicago.”).
More important, Congress claimed there was a medical
consensus that the banned procedure is never necessary.
Congressional Findings (1), in notes following 18 U. S. C.
§1531 (2000 ed., Supp. IV), p. 767. But the evidence “very

includes letters from numerous individual physicians
stating that pregnant women’s health would be jeopard

Planned Parenthood, 320 F. Supp. 2d, at 1021 (“Congress

medical groups supported the ban. In fact, “all of the
government’s own witnesses disagreed with many of the
specific congressional findings.” Id., at 1024.
C
In contrast to Congress, the District Courts made find
ings after full trials at which all parties had the opportu
nity to present their best evidence. The courts had the
benefit of “much more extensive medical and scientific
evidence . . . concerning the safety and necessity of intact
D&Es.” Planned Parenthood, 320 F. Supp. 2d, at 1014; cf.
National Abortion Federation, 330 F. Supp. 2d, at 482
(District Court “heard more evidence during its trial than
Congress heard over the span of eight years.”).
During the District Court trials, “numerous” “extraor
dinarily accomplished” and “very experienced” medical
experts explained that, in certain circumstances and for
certain women, intact D&E is safer than alternative pro
cedures and necessary to protect women’s health.
Carhart, 331 F. Supp. 2d, at 1024–1027; see Planned
Parenthood, 320 F. Supp. 2d, at 1001 (“[A]ll of the doctors
who actually perform intact D&Es concluded that in their
opinion and clinical judgment, intact D&Es remain the
10 GONZALES v. CARHART
GINSBURG, J., dissenting
safest option for certain individual women under certain
individual health circumstances, and are significantly
safer for these women than other abortion techniques, and
are thus medically necessary.”); cf. ante, at 31 (“Respon
dents presented evidence that intact D&E may be the
safest method of abortion, for reasons similar to those
adduced in Stenberg.”).
According to the expert testimony plaintiffs introduced,
the safety advantages of intact D&E are marked for
women with certain medical conditions, for example,
uterine scarring, bleeding disorders, heart disease, or
compromised immune systems. See Carhart, 331 F. Supp.
2d, at 924–929, 1026–1027; National Abortion Federation,
330 F. Supp. 2d, at 472–473; Planned Parenthood, 320
F. Supp. 2d, at 992–994, 1001. Further, plaintiffs’ experts
testified that intact D&E is significantly safer for women
with certain pregnancy-related conditions, such as pla
centa previa and accreta, and for women carrying fetuses
with certain abnormalities, such as severe hydrocephalus.
See Carhart, 331 F. Supp. 2d, at 924, 1026–1027; National

Stenberg, 530 U. S., at 929; Brief for ACOG as Amicus
Curiae 2, 13–16.
Intact D&E, plaintiffs’ experts explained, provides
safety benefits over D&E by dismemberment for several
reasons: First, intact D&E minimizes the number of times
a physician must insert instruments through the cervix
and into the uterus, and thereby reduces the risk of
trauma to, and perforation of, the cervix and uterus—the
most serious complication associated with nonintact D&E.
See Carhart, 331 F. Supp. 2d, at 923–928, 1025; National
Abortion Federation, 330 F. Supp. 2d, at 471; Planned
Parenthood, 320 F. Supp. 2d, at 982, 1001. Second, remov
ing the fetus intact, instead of dismembering it in utero,
decreases the likelihood that fetal tissue will be retained

GINSBURG, J., dissenting
in the uterus, a condition that can cause infection, hemor
rhage, and infertility. See Carhart, 331 F. Supp. 2d, at
923–928, 1025–1026; National Abortion Federation, 330
F. Supp. 2d, at 472; Planned Parenthood, 320 F. Supp. 2d,
at 1001. Third, intact D&E diminishes the chances of
exposing the patient’s tissues to sharp bony fragments
sometimes resulting from dismemberment of the fetus.
See Carhart, 331 F. Supp. 2d, at 923–928, 1026; National
Abortion Federation, 330 F. Supp. 2d, at 471; Planned
Parenthood, 320 F. Supp. 2d, at 1001. Fourth, intact D&E
takes less operating time than D&E by dismemberment,
and thus may reduce bleeding, the risk of infection, and
complications relating to anesthesia. See Carhart, 331
F. Supp. 2d, at 923–928, 1026; National Abortion Federa
tion, 330 F. Supp. 2d, at 472; Planned Parenthood, 320

929, 932; Brief for ACOG as Amicus Curiae 2, 11–13.
Based on thoroughgoing review of the trial evidence and
the congressional record, each of the District Courts to
consider the issue rejected Congress’ findings as unrea
sonable and not supported by the evidence. See Carhart,
331 F. Supp. 2d, at 1008–1027; National Abortion Federa
tion, 330 F. Supp. 2d, at 482, 488–491; Planned Parent
hood, 320 F. Supp. 2d, at 1032. The trial courts concluded,
in contrast to Congress’ findings, that “significant medical
authority supports the proposition that in some circum
stances, [intact D&E] is the safest procedure.” Id., at 1033
(quoting Stenberg, 530 U. S., at 932); accord Carhart, 331
F. Supp. 2d, at 1008–1009, 1017–1018; National Abortion

5 Even the District Court for the Southern District of New York,
which was more skeptical of the health benefits of intact D&E, see ante,
at 32, recognized: “[T]he Government’s own experts disagreed with
almost all of Congress’s factual findings”; a “significant body of medical
opinion” holds that intact D&E has safety advantages over nonintact
D&E; “[p]rofessional medical associations have also expressed their

GINSBURG, J., dissenting
U. S., at 932 (“[T]he record shows that significant medical
authority supports the proposition that in some circum
stances, [intact D&E] would be the safest procedure.”).
The District Courts’ findings merit this Court’s respect.
See, e.g., Fed. Rule Civ. Proc. 52(a); Salve Regina College
v. Russell, 499 U. S. 225, 233 (1991). Today’s opinion
supplies no reason to reject those findings. Nevertheless,
despite the District Courts’ appraisal of the weight of the
evidence, and in undisguised conflict with Stenberg, the
Court asserts that the Partial-Birth Abortion Ban Act can
survive “when . . . medical uncertainty persists.” Ante, at
33. This assertion is bewildering. Not only does it defy
the Court’s longstanding precedent affirming the necessity
of a health exception, with no carve-out for circumstances
of medical uncertainty, see supra, at 4–5; it gives short
shrift to the records before us, carefully canvassed by the
District Courts. Those records indicate that “the majority
of highly-qualified experts on the subject believe intact
D&E to be the safest, most appropriate procedure under
certain circumstances.” Planned Parenthood, 320 F. Supp.
2d, at 1034. See supra, at 9–10.
The Court acknowledges some of this evidence, ante, at
31, but insists that, because some witnesses disagreed
with the ACOG and other experts’ assessment of risk, the
Act can stand. Ante, at 32–33, 37. In this insistence, the
Court brushes under the rug the District Courts’ well-
supported findings that the physicians who testified that
intact D&E is never necessary to preserve the health of a
woman had slim authority for their opinions. They had no
training for, or personal experience with, the intact D&E

view that [intact D&E] may be the safest procedure for some women”;
and “[t]he evidence indicates that the same disagreement among

time that Congress was considering the legislation, despite Congress’s
findings to the contrary.” National Abortion Federation, 330 F. Supp.

occasions. See Planned Parenthood, 320 F. Supp. 2d, at

tion Federation, 330 F. Supp. 2d, at 462–464. Even in
dulging the assumption that the Government witnesses
were equally qualified to evaluate the relative risks of
abortion procedures, their testimony could not erase the
“significant medical authority support[ing] the proposition
that in some circumstances, [intact D&E] would be the
safest procedure.” Stenberg, 530 U. S., at 932.6

A
The Court offers flimsy and transparent justifications
for upholding a nationwide ban on intact D&E sans any
exception to safeguard a women’s health. Today’s ruling,
the Court declares, advances “a premise central to [Ca
sey’s] conclusion”—i.e., the Government’s “legitimate and
substantial interest in preserving and promoting fetal
——————
6 The majority contends that “[i]f the intact D&E procedure is truly
necessary in some circumstances, it appears likely an injection that
kills the fetus is an alternative under the Act that allows the doctor to
perform the procedure.” Ante, at 34–35. But a “significant body of
medical opinion believes that inducing fetal death by injection is almost
always inappropriate to the preservation of the health of women
undergoing abortion because it poses tangible risk and provides no
benefit to the woman.” Carhart v. Ashcroft, 331 F. Supp. 2d 805, 1028
(Neb. 2004) (internal quotation marks omitted), aff’d, 413 F. 3d 791
(CA8 2005). In some circumstances, injections are “absolutely [medi
cally] contraindicated.” 331 F. Supp. 2d, at 1027. See also id., at 907–
912; National Abortion Federation, 330 F. Supp. 2d, at 474–475;
Planned Parenthood, 320 F. Supp. 2d, at 995–997. The Court also
identifies medical induction of labor as an alternative. See ante, at 9.
That procedure, however, requires a hospital stay, ibid., rendering it
inaccessible to patients who lack financial resources, and it too is
considered less safe for many women, and impermissible for others.
See Carhart, 331 F. Supp. 2d, at 940–949, 1017; National Abortion
Federation, 330 F. Supp. 2d, at 468–470; Planned Parenthood, 320

life.” Ante, at 14. See also ante, at 15 (“[W]e must deter
mine whether the Act furthers the legitimate interest of
the Government in protecting the life of the fetus that may
become a child.”). But the Act scarcely furthers that in
terest: The law saves not a single fetus from destruction,
for it targets only a method of performing abortion. See
Stenberg, 530 U. S., at 930. And surely the statute was
not designed to protect the lives or health of pregnant
women. Id., at 951 (GINSBURG, J., concurring); cf. Casey,
505 U. S., at 846 (recognizing along with the State’s le
gitimate interest in the life of the fetus, its “legitimate
interes[t] . . . in protecting the health of the woman” (em
phasis added)). In short, the Court upholds a law that,
while doing nothing to “preserv[e] . . . fetal life,” ante, at
14, bars a woman from choosing intact D&E although her
doctor “reasonably believes [that procedure] will best
protect [her].” Stenberg, 530 U. S., at 946 (STEVENS, J.,
concurring).
As another reason for upholding the ban, the Court
emphasizes that the Act does not proscribe the nonintact
D&E procedure. See ante, at 34. But why not, one might
ask. Nonintact D&E could equally be characterized as
“brutal,” ante, at 26, involving as it does “tear[ing] [a
fetus] apart” and “ripp[ing] off” its limbs, ante, at 4, 6.
“[T]he notion that either of these two equally gruesome
procedures . . . is more akin to infanticide than the other,
or that the State furthers any legitimate interest by ban
ning one but not the other, is simply irrational.” Stenberg,
530 U. S., at 946–947 (STEVENS, J., concurring).
Delivery of an intact, albeit nonviable, fetus warrants
special condemnation, the Court maintains, because a
fetus that is not dismembered resembles an infant. Ante,
at 28. But so, too, does a fetus delivered intact after it is
terminated by injection a day or two before the surgical
evacuation, ante, at 5, 34–35, or a fetus delivered through
medical induction or cesarean, ante, at 9. Yet, the avail

GINSBURG, J., dissenting
ability of those procedures—along with D&E by dismem
berment—the Court says, saves the ban on intact D&E
from a declaration of unconstitutionality. Ante, at 34–35.
Never mind that the procedures deemed acceptable might
put a woman’s health at greater risk. See supra, at 13,
and n. 6; cf. ante, at 5, 31–32.
Ultimately, the Court admits that “moral concerns” are
at work, concerns that could yield prohibitions on any
abortion. See ante, at 28 (“Congress could . . . conclude
that the type of abortion proscribed by the Act requires
specific regulation because it implicates additional ethical
and moral concerns that justify a special prohibition.”).
Notably, the concerns expressed are untethered to any
ground genuinely serving the Government’s interest in
preserving life. By allowing such concerns to carry the
day and case, overriding fundamental rights, the Court
dishonors our precedent. See, e.g., Casey, 505 U. S., at 850
(“Some of us as individuals find abortion offensive to our
most basic principles of morality, but that cannot control
our decision. Our obligation is to define the liberty of all,
not to mandate our own moral code.”); Lawrence v. Texas,
539 U. S. 558, 571 (2003) (Though “[f]or many persons
[objections to homosexual conduct] are not trivial concerns
but profound and deep convictions accepted as ethical and
moral principles,” the power of the State may not be used
“to enforce these views on the whole society through op
eration of the criminal law.” (citing Casey, 505 U. S., at
850)).
Revealing in this regard, the Court invokes an antiabor
tion shibboleth for which it concededly has no reliable
evidence: Women who have abortions come to regret their
choices, and consequently suffer from “[s]evere depression
and loss of esteem.” Ante, at 29.7 Because of women’s

fragile emotional state and because of the “bond of love the
mother has for her child,” the Court worries, doctors may
withhold information about the nature of the intact D&E
procedure. Ante, at 28–29.8 The solution the Court ap
proves, then, is not to require doctors to inform women,
accurately and adequately, of the different procedures and
their attendant risks. Cf. Casey, 505 U. S., at 873 (plural
ity opinion) (“States are free to enact laws to provide a
reasonable framework for a woman to make a decision
that has such profound and lasting meaning.”). Instead,
the Court deprives women of the right to make an
autonomous choice, even at the expense of their safety.9
——————
8 Notwithstanding the “bond of love” women often have with their
children, see ante, at 28, not all pregnancies, this Court has recognized,
are wanted, or even the product of consensual activity. See Casey, 505
U. S., at 891 (“[O]n an average day in the United States, nearly 11,000

9 Eliminating or reducing women’s reproductive choices is manifestly
not a means of protecting them. When safe abortion procedures cease
to be an option, many women seek other means to end unwanted or
coerced pregnancies. See, e.g., World Health Organization, Unsafe
Abortion: Global and Regional Estimates of the Incidence of Unsafe
Abortion and Associated Mortality in 2000, pp. 3, 16 (4th ed. 2004)

This way of thinking reflects ancient notions about
women’s place in the family and under the Constitution—
ideas that have long since been discredited. Compare, e.g.,
Muller v. Oregon, 208 U. S. 412, 422–423 (1908) (“protec

women only held permissible in view of women’s “physical
structure and a proper discharge of her maternal func

ley, J., concurring) (“Man is, or should be, woman’s protec

delicacy which belongs to the female sex evidently unfits it
for many of the occupations of civil life. . . . The paramount
destiny and mission of woman are to fulfil[l] the noble and

Virginia, 518 U. S. 515, 533, 542, n. 12 (1996) (State may
not rely on “overbroad generalizations” about the “talents,

Though today’s majority may regard women’s feelings
on the matter as “self-evident,” ante, at 29, this Court has
repeatedly confirmed that “[t]he destiny of the woman
must be shaped . . . on her own conception of her spiritual
imperatives and her place in society.” Casey, 505 U. S., at
852. See also id., at 877 (plurality opinion) (“[M]eans

B
In cases on a “woman’s liberty to determine whether to

GINSBURG, J., dissenting
[continue] her pregnancy,” this Court has identified viabil
ity as a critical consideration. See Casey, 505 U. S., at
869–870 (plurality opinion). “[T]here is no line [more
workable] than viability,” the Court explained in Casey,
for viability is “the time at which there is a realistic possi
bility of maintaining and nourishing a life outside the
womb, so that the independent existence of the second life
can in reason and all fairness be the object of state protec
tion that now overrides the rights of the woman. . . . In
some broad sense it might be said that a woman who fails
to act before viability has consented to the State’s inter
vention on behalf of the developing child.” Id., at 870.
Today, the Court blurs that line, maintaining that “[t]he
Act [legitimately] appl[ies] both previability and postvi
ability because . . . a fetus is a living organism while
within the womb, whether or not it is viable outside the
womb.” Ante, at 17. Instead of drawing the line at viabil
ity, the Court refers to Congress’ purpose to differentiate
“abortion and infanticide” based not on whether a fetus
can survive outside the womb, but on where a fetus is
anatomically located when a particular medical procedure
is performed. See ante, at 28 (quoting Congressional
Findings (14)(G), in notes following 18 U. S. C. §1531
(2000 ed., Supp. IV), p. 769).
One wonders how long a line that saves no fetus from
destruction will hold in face of the Court’s “moral con
cerns.” See supra, at 15; cf. ante, at 16 (noting that “[i]n
this litigation” the Attorney General “does not dispute that
the Act would impose an undue burden if it covered stan
dard D&E”). The Court’s hostility to the right Roe and
Casey secured is not concealed. Throughout, the opinion
refers to obstetrician-gynecologists and surgeons who
perform abortions not by the titles of their medical special
ties, but by the pejorative label “abortion doctor.” Ante, at
14, 24, 25, 31, 33. A fetus is described as an “unborn
child,” and as a “baby,” ante, at 3, 8; second-trimester,
20 GONZALES v. CARHART

previability abortions are referred to as “late-term,” ante,
at 26; and the reasoned medical judgments of highly
trained doctors are dismissed as “preferences” motivated
by “mere convenience,” ante, at 3, 37. Instead of the
heightened scrutiny we have previously applied, the Court
determines that a “rational” ground is enough to uphold
the Act, ante, at 28, 37. And, most troubling, Casey’s
principles, confirming the continuing vitality of “the essen
tial holding of Roe,” are merely “assume[d]” for the mo
ment, ante, at 15, 31, rather than “retained” or “reaf
firmed,” Casey, 505 U. S., at 846.

The Court further confuses our jurisprudence when it
declares that “facial attacks” are not permissible in “these
circumstances,” i.e., where medical uncertainty exists.
Ante, at 37; see ibid. (“In an as-applied challenge the
nature of the medical risk can be better quantified and
balanced than in a facial attack.”). This holding is per
plexing given that, in materially identical circumstances
we held that a statute lacking a health exception was
unconstitutional on its face. Stenberg, 530 U. S., at 930;
see id., at 937 (in facial challenge, law held unconstitu
tional because “significant body of medical opinion be
lieves [the] procedure may bring with it greater safety for
some patients” (emphasis added)). See also Sabri v.
United States, 541 U. S. 600, 609–610 (2004) (identifying
abortion as one setting in which we have recognized the
validity of facial challenges); Fallon, Making Sense of
Overbreadth, 100 Yale L. J. 853, 859, n. 29 (1991)
(“[V]irtually all of the abortion cases reaching the Su
preme Court since Roe v. Wade, 410 U. S. 113 (1973), have
involved facial attacks on state statutes, and the Court,

Statutes, 46 Stan. L. Rev. 235, 271–276 (1994).
Without attempting to distinguish Stenberg and earlier
decisions, the majority asserts that the Act survives re
view because respondents have not shown that the ban on
intact D&E would be unconstitutional “in a large fraction
of relevant cases.” Ante, at 38 (citing Casey, 505 U. S., at
895). But Casey makes clear that, in determining whether
any restriction poses an undue burden on a “large frac
tion” of women, the relevant class is not “all women,” nor
“all pregnant women,” nor even all women “seeking abor
tions.” 505 U. S., at 895. Rather, a provision restricting
access to abortion, “must be judged by reference to those
[women] for whom it is an actual rather than an irrelevant
restriction,” ibid. Thus the absence of a health exception
burdens all women for whom it is relevant—women who,
in the judgment of their doctors, require an intact D&E
because other procedures would place their health at
risk.10 Cf. Stenberg, 530 U. S., at 934 (accepting the “rela
tive rarity” of medically indicated intact D&Es as true but
not “highly relevant”—for “the health exception question
is whether protecting women’s health requires an excep
tion for those infrequent occasions”); Ayotte, 546 U. S., at
328 (facial challenge entertained where “[i]n some very
small percentage of cases . . . women . . . need immediate
abortions to avert serious, and often irreversible damage
to their health”). It makes no sense to conclude that this
facial challenge fails because respondents have not shown
that a health exception is necessary for a large fraction of

nator are the same: The health exception reaches only those cases
where a woman’s health is at risk. Perhaps for this reason, in mandat
ing safeguards for women’s health, we have never before invoked the
“large fraction” test.

second-trimester abortions, including those for which a
health exception is unnecessary: The very purpose of a
health exception is to protect women in exceptional cases.

If there is anything at all redemptive to be said of to
day’s opinion, it is that the Court is not willing to foreclose
entirely a constitutional challenge to the Act. “The Act is
open,” the Court states, “to a proper as-applied challenge
in a discrete case.” Ante, at 38; see ante, at 37 (“The Gov
ernment has acknowledged that preenforcement, as-
applied challenges to the Act can be maintained.”). But
the Court offers no clue on what a “proper” lawsuit might
look like. See ante, at 37–38. Nor does the Court explain
why the injunctions ordered by the District Courts should
not remain in place, trimmed only to exclude instances in
which another procedure would safeguard a woman’s
health at least equally well. Surely the Court cannot
mean that no suit may be brought until a woman’s health
is immediately jeopardized by the ban on intact D&E. A
woman “suffer[ing] from medical complications,” ante, at
38, needs access to the medical procedure at once and
cannot wait for the judicial process to unfold. See Ayotte,
546 U. S., at 328.
The Court appears, then, to contemplate another law
suit by the initiators of the instant actions. In such a
second round, the Court suggests, the challengers could
succeed upon demonstrating that “in discrete and well-
defined instances a particular condition has or is likely to
occur in which the procedure prohibited by the Act must
be used.” Ante, at 37. One may anticipate that such a
preenforcement challenge will be mounted swiftly, to ward
off serious, sometimes irremediable harm, to women
whose health would be endangered by the intact D&E
prohibition.
The Court envisions that in an as-applied challenge,

GINSBURG, J., dissenting
“the nature of the medical risk can be better quantified
and balanced.” Ibid. But it should not escape notice that
the record already includes hundreds and hundreds of
pages of testimony identifying “discrete and well-defined
instances” in which recourse to an intact D&E would
better protect the health of women with particular condi
tions. See supra, at 10–11. Record evidence also docu
ments that medical exigencies, unpredictable in advance,
may indicate to a well-trained doctor that intact D&E is
the safest procedure. See ibid. In light of this evidence,
our unanimous decision just one year ago in Ayotte coun
sels against reversal. See 546 U. S., at 331 (remanding for
reconsideration of the remedy for the absence of a health
exception, suggesting that an injunction prohibiting un
constitutional applications might suffice).
The Court’s allowance only of an “as-applied challenge
in a discrete case,” ante, at 38—jeopardizes women’s
health and places doctors in an untenable position. Even
if courts were able to carve-out exceptions through piece
meal litigation for “discrete and well-defined instances,”
ante, at 37, women whose circumstances have not been
anticipated by prior litigation could well be left unpro
tected. In treating those women, physicians would risk
criminal prosecution, conviction, and imprisonment if they
exercise their best judgment as to the safest medical pro
cedure for their patients. The Court is thus gravely mis
taken to conclude that narrow as-applied challenges are
“the proper manner to protect the health of the woman.”
Cf. ibid.

As the Court wrote in Casey, “overruling Roe’s central
holding would not only reach an unjustifiable result under
principles of stare decisis, but would seriously weaken the
Court’s capacity to exercise the judicial power and to
function as the Supreme Court of a Nation dedicated to
24 GONZALES v. CARHART
GINSBURG, J., dissenting
the rule of law.” 505 U. S., at 865. “[T]he very concept of
the rule of law underlying our own Constitution requires
such continuity over time that a respect for precedent is,
by definition, indispensable.” Id., at 854. See also id., at
867 (“[T]o overrule under fire in the absence of the most
compelling reason to reexamine a watershed decision
would subvert the Court’s legitimacy beyond any serious
question.”).
Though today’s opinion does not go so far as to discard
Roe or Casey, the Court, differently composed than it was
when we last considered a restrictive abortion regulation,
is hardly faithful to our earlier invocations of “the rule of
law” and the “principles of stare decisis.” Congress im
posed a ban despite our clear prior holdings that the State
cannot proscribe an abortion procedure when its use is
necessary to protect a woman’s health. See supra, at 7,
n. 4. Although Congress’ findings could not withstand the
crucible of trial, the Court defers to the legislative override
of our Constitution-based rulings. See supra, at 7–9. A
decision so at odds with our jurisprudence should not have
staying power.
In sum, the notion that the Partial-Birth Abortion Ban
Act furthers any legitimate governmental interest is, quite
simply, irrational. The Court’s defense of the statute
provides no saving explanation. In candor, the Act, and
the Court’s defense of it, cannot be understood as anything
other than an effort to chip away at a right declared again
and again by this Court—and with increasing comprehen
sion of its centrality to women’s lives. See supra, at 3,
n. 2; supra, at 7, n. 4. When “a statute burdens constitu
tional rights and all that can be said on its behalf is that it
is the vehicle that legislators have chosen for expressing
their hostility to those rights, the burden is undue.” Sten

ner, C. J., dissenting)).
