In Jane L. v. Bangerter,
The Supreme Court granted certiorari and limited its review to our holding that the two provisions of the Utah statute were not sev-erable. The Court summarily reversed the judgment as to that issue, and remanded the case to us for further proceedings. See Leavitt v. Jane L., — U.S. -,
Section 302(3) provides: “After 20 weeks gestational age, measured from the date of conception, an abortion may be performed only for those purposes and circumstances described in Subsections 2(a), (d), and (e).” Utah Code Ann. § 76-7-302(3).
In Casey, the Supreme Court reaffirmed the central holding of Roe v. Wade,
viability marks the earliest point at which the State’s interest in fetal life is constitutionally adequate to justify a legislative ban on nontherapeutic abortions. The soundness or unsoundness of that constitutional judgment in no sense turns on whether viability occurs at approximately 28 weeks, as was usual at the time of Roe, at 23 to 24 weeks, as it sometimes does today, or at some moment even slightly earlier in pregnancy, as it may if fetal respiratory capacity can somehow be enhanced in the future. Whenever it may occur, the attainment of viability may continue to serve as the critical fact, just as it*1115 has done since Roe was decided; which is to say that no change in Roe’s factual underpinning has left its central holding obsolete, and none supports an argument for overruling it.
Casey,
After the decision in Roe, the Supreme Court addressed the critical definition of viability in a series of cases. In Planned Parenthood v. Danforth,
[I]t is not the proper function of the legislature or the courts to place viability, which essentially is a medical concept, at a specific point in the gestation period. The time when viability is achieved may vary with each pregnancy, and the determination of whether a particular fetus is viable is, and must be, a matter for the judgment of the responsible attending physician.
Id.
In Colautti v. Franklin,
We reaffirm these principles. Viability is reached when, in the judgment of the attending physician on the particular facts of the case before him, there is a reasonable likelihood of the fetus’ sustained survival outside the womb, with or without artificial support. Because this point may differ with each pregnancy, neither the legislature nor the courts may proclaim one of the elements entering into the ascertainment of viability — be it weeks of gestation or fetal weight or any other single factor— as the determinant of when the State has a compelling interest in the life or health of the fetus. Viability is the critical'point. And we have recognized no attempt to stretch the point of viability one way or the other.
Id. at 388-89,
It is indisputable that section 302(3) of the Utah abortion statute, which effectively defines viability as occurring at twenty weeks gestational age, is directly contrary to the Supreme Court authority set out above. Defendants argue that the section nonetheless passes constitutional muster under Casey. In deciding that issue, we must first determine the standard of review applicable after Casey.
In Casey, the Court held that “[o]nly where state regulation imposes an undue burden on a woman’s ability to [choose to terminate or continue her pregnancy before viability] does the power of the State reach into the heart of the liberty protected by the Due Process Clause.” Casey,
That determination does not end the inquiry, however, because the standard applicable to previability regulations after Casey is a matter of some dispute. See Planned Parenthood v. Miller,
Under Casey, “[a]n undue burden exists, and therefore a provision of law is invalid, 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.”
As we pointed out in Jane L. IV,
We also conclude that the section is invalid because it has an impermissible effect. “[A] statute which, while furthering the interest in potential life or some other valid state interest, has the effect of placing a substantial obstacle in the path of a woman’s choice cannot be considered a permissible means of serving its legitimate ends.” Casey,
The district court held as a matter of law that section 302(3) nevertheless does not impose an undue burden under Casey because the record contains no evidence that any woman wants or has attempted to obtain such a late nontherapeutic abortion in Utah. Jane L. III,
We accordingly hold that section 302(3) has both the purpose and effect of placing a substantial obstacle in the path of a woman seeking to abort a nonviable fetus. It therefore imposes an undue burden on a woman’s right to choose. The State’s arguments to the contrary are disingenuous and unpersuasive because they are grounded on its continued refusal to accept governing Supreme Court authority holding that viability is a matter to be determined by an attending physician, and that until viability is actually present the State may not prevent a woman from choosing to abort.
In sum, we hold that section 302(3) is unconstitutional in that it unduly burdens a woman’s right to choose to abort a nonviable fetus.
Notes
. In addition to holding that Utah Code Ann. § 76-7-302(3) (1995) was not severable, we also held that the provision on fetal experimentation, id. § 310, was unconstitutionally vague, and that the sections governing the choice of methods for postviability abortions, id. §§ 307, 308, were unconstitutional. See Jane L. IV,
. The panel heard argument on this issue before deciding Jane L. IV. We have determined unanimously that additional oral argument would not materially assist the determination of this appeal. See Fed.R.App.P. 34(a); 10th Cir.R. 34.1.9.
.Gestational age is generally "determined by computing the time from the first day of the last menstrual period [Imp].” 2 J.E. Schmidt, M.D., Attorneys' Dictionary of Medicine at G-63 (1996). Utah law, however, measures gestational age differently and perhaps uniquely by computing it from the date of conception. Thus, "20 weeks gestational age” as used in section 302(3) equates with 22 weeks gestational age as this computation is generally made.
. The undue burden test is meant to evaluate the constitutionality of regulations that burden a woman's right to choose a previability abortion. Section 302(3) does much more than pose an obstacle to that choice. It defines viability in terms of gestational age. For a woman seeking the nontherapeutic abortion of a fetus that is not viable despite fitting the statutory definition in section 302(3), however, that section goes beyond creating a hindrance and imposes an outright ban. Rather than apply Planned Parenthood v. Casey,
. Neither the district court nor the State has focused on the fact that under Casey, a law is invalid if either its purpose or effect is to place a substantial obstacle in the path of a woman seeking to abort a nonviable fetus. See Casey,
. The State contends these cases are no longer valid after Casey to the extent they commit the determination of viability to the medical judgment of the attending physician and prohibit a legislature from defining viability in terms of gestational age. To the contrary, we view the Court’s reaffirmation in Casey that “[w]henever it may occur, the attainment of viability may continue to serve as the critical fact, just as it has done since Roe was decided,”
. Because we strike down section 302(3) as unconstitutional, we need not reach plaintiffs' challenge to one of the circumstances in which a woman may obtain a postviability abortion. Under section 302(3), such an abortion is permitted, inter alia, to prevent grave damage to the woman’s health. Plaintiffs argue that this provision goes beyond the holding in Roe, reaffirmed in Casey, that a State may proscribe postviability “abortion except where it is necessary, in appropriate medical judgment, for the preservation of the life or health of the mother.” Casey,
We note nevertheless that we addressed identical language in Jane L. IV when considering the constitutionality of the Utah provisions governing a doctor's choice of methods for performing postviability abortions. See Jane L. IV,
