870
Opinion of O'Connor, Kennedy, and Souter, JJ.
We conclude the line should be drawn at viability, so that before that time the woman has a right to choose to terminate her pregnancy. We adhere to this principle for two reasons. First, as we have said, is the doctrine of stare decisis. Any judicial act of line-drawing may seem somewhat arbitrary, but Roe was a reasoned statement, elaborated with great care. We have twice reaffirmed it in the face of great opposition. See Thornburgh v. American College of Obstetricians and Gynecologists, 476 U. S., at 759; Akron I, 462 U. S., at 419-420. Although we must overrule those parts of Thornburgh and Akron I which, in our view, are inconsistent with Roe's statement that the State has a legitimate interest in promoting the life or potential life of the unborn, see infra, at 882-883, the central premise of those cases represents an unbroken commitment by this Court to the essential holding of Roe. It is that premise which we reaffirm today.
The second reason is that the concept of viability, as we noted in Roe, is the time at which there is a realistic possibility 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 protection that now overrides the rights of the woman. See Roe v. Wade, 410 U. S., at 163. Consistent with other constitutional norms, legislatures may draw lines which appear arbitrary without the necessity of offering a justification. But courts may not. We must justify the lines we draw. And there is no line other than viability which is more workable. To be sure, as we have said, there may be some medical developments that affect the precise point of viability, see supra, at 860, but this is an imprecision within tolerable limits given that the medical community and all those who must apply its discoveries will continue to explore the matter. The viability line also has, as a practical matter, an element of fairness. In some broad sense it might be said that a woman who fails to act before viability has consented to the State's intervention on behalf of the developing child.
