Opinion of the Court
wrongly removed an issue from the people and the democratic process. As Justice White later explained, “decisions that find in the Constitution principles or values that cannot fairly be read into that document usurp the people’s authority, for such decisions represent choices that the people have never made and that they cannot disavow through corrective legislation. For this reason, it is essential that this Court maintain the power to restore authority to its proper possessors by correcting constitutional decisions that, on reconsideration, are found to be mistaken.” Thornburgh, 476 U. S., at 787 (dissenting opinion).
B
The quality of the reasoning. Under our precedents, the quality of the reasoning in a prior case has an important bearing on whether it should be reconsidered. See Janus, 585 U. S., at ___ (slip op., at 38); Ramos, 590 U. S., at ___–___ (opinion of Kavanaugh, J.) (slip op., at 7–8). In Part II, supra, we explained why Roe was incorrectly decided, but that decision was more than just wrong. It stood on exceptionally weak grounds.
Roe found that the Constitution implicitly conferred a right to obtain an abortion, but it failed to ground its decision in text, history, or precedent. It relied on an erroneous historical narrative; it devoted great attention to and presumably relied on matters that have no bearing on the meaning of the Constitution; it disregarded the fundamental difference between the precedents on which it relied and the question before the Court; it concocted an elaborate set of rules, with different restrictions for each trimester of pregnancy, but it did not explain how this veritable code could be teased out of anything in the Constitution, the history of abortion laws, prior precedent, or any other cited source; and its most important rule (that States cannot protect fetal life prior to “viability”) was never raised by any
