"The joint opinion thus turns to what can only be described as an unconventional—and unconvincing —notion of reliance, a view based on the surmise that the availability of abortion since Roe has led to "two decades of economic and social developments" that would be undercut if the error of Roe were recognized. Ibid. The joint opinion's assertion of this fact is undeveloped and totally conclusory. In fact, one can not be sure to what economic and social developments the opinion is referring. Surely it is dubious to suggest that women have reached their "places in society" in reliance upon Roe, rather than as a result of their determination to obtain higher education and compete with men in the job market, and of society's increasing recognition of their ability to fill positions that were previously thought to be reserved only for men. Ibid. In the end, having failed to put forth any evidence to prove any true reliance, the joint opinion's argument is based solely on generalized assertions about the national psyche, on a belief that the people of this country have grown accustomed to the Roe decision over the last 19 years and have "ordered their thinking and living around" it. Ibid. As an initial matter, one might inquire how the joint opinion can view the "central holding" of Roe as so deeply rooted in our constitutional culture, when it so casually uproots and disposes of that same decision's trimester framework. Furthermore, at various points in the past, the same could have been said about this Court's erroneous decisions that the Constitution allowed "separate but equal" treatment of minorities, see Plessy v. Ferguson, 163 U.S. 537, 16 S.Ct. 1138, 41 L.Ed. 256 (1896), or that "liberty" under the Due Process Clause protected "freedom of contract." See Adkins v. Children's Hospital of D.C., 261 U.S. 525, 43 S.Ct. 394, 67 L.Ed. 785 (1923); Lochner v. New York, 198 U.S. 45, 25 S.Ct. 539, 49 L.Ed. 937 (1905). The "separate but equal" doctrine lasted 58 years after Plessy, and Lochner's protection of contractual freedom lasted 32 years. However, the simple fact that a generation or more had grown used to these major decisions did not prevent the Court from correcting its errors in those cases, nor should it prevent us from correctly interpreting the Constitution here. See Brown v. Board of Education, 347 U.S. 483, 74 S.Ct. 686, 98 L.Ed. 873 (1954) (rejecting the "separate but equal" doctrine); West Coast Hotel Co. v. Parrish, 300 U.S. 379, 57 S.Ct. 578, 81 L.Ed. 703 (1937) (overruling Adkins v. Children's Hospital, supra, in upholding Washington's minimum wage law). Apparently realizing that conventional stare decisis principles do not support its position, the joint opinion advances a belief that retaining a portion of Roe is necessary to protect the "legitimacy" of this Court. Ante, at ____. Because the Court must take care to render decisions "grounded truly in principle," and not simply as political and social compromises, ante, at ____, the joint opinion properly declares it to be this Court's duty to ignore the public criticism and protest that may arise as a result of a decision. Few would quarrel with this statement, although it may be doubted that Members of this Court, holding their tenure as they do during constitutional "good behavior," are at all likely to be intimidated by such public protests. But the joint opinion goes on to state that when the Court "resolve[s] the sort of intensely divisive controversy reflected in Roe and those rare, comparable cases," its decision is exempt from reconsideration under established principles of stare decisis in constitutional cases. Ante, at ____. This is so, the joint opinion contends, because in those "intensely divisive" cases the Court has "call[ed] the contending sides of a national controversy to end their national division by accepting a common mandate rooted in the Constitution," and must therefore take special care not to be perceived as "surrender[ing] to political pressure" and continued opposition. Ante, at 2815. This is a truly novel principle, one which is contrary to both the Court's historical practice and to the Court's traditional willingness to tolerate criticism of its opinions. Under this principle, when the Court has ruled on a divisive issue, it is apparently prevented from overruling that decision for the sole reason that it was incorrect, unless opposition to the original decision has died away."
