The Supreme Court on Friday formally overturned its 49-year-old landmark Roe v. Wade decision, and with it ended a half-century of constitutionally guaranteed abortion rights in the United States.

The 6-3 decision in the case, Dobbs v. Jackson Women’s Health Organization, was telegraphed in May by an unprecedented leak of an early draft of the majority opinion, written by Justice Samuel Alito. But even though the final, official version was slightly less strident than the leaked document, the impact is the same. The right to an abortion has been eliminated as if it never existed at all. The decision about whether to allow the procedure now falls to individual state governments, and only 16, plus the District of Columbia, have passed laws to preserve the option, while two others have state constitutional protections that have been cited by state courts as protections for abortion.

The majority opinion, whose signers included Justice Clarence Thomas and all three justices appointed by President Donald Trump — Neil Gorsuch, Brett Kavanaugh, and Amy Coney Barrett — said in no uncertain terms that 1973’s Roe, and a 1992 case that reaffirmed that right, Planned Parenthood of Southeastern Pennsylvania v. Casey, were wrongly decided.

“The Constitution makes no reference to abortion, and no such right is implicitly protected by any constitutional provision,” wrote Alito. “It is time to heed the Constitution and return the issue of abortion to the people’s elected representatives.”

Chief Justice John Roberts, an abortion opponent who had telegraphed when the case was argued in December that he was in favor of upholding the Mississippi law at the center of the case, agreed with the judgment but filed his own, concurring opinion in which he said he would not have gone as far. “I would take a more measured course,” he wrote. “The Court’s opinion is thoughtful and thorough, but those virtues cannot compensate for the fact that its dramatic and consequential ruling is unnecessary to decide the case before us.”

On the other hand, the three remaining liberals on the court, Sonia Sotomayor, Elena Kagan, and Stephen Breyer, who is retiring at the end of this term, pulled no punches.

“One result of today’s decision is certain: the curtailment of women’s rights, and of their status as free and equal citizens,” wrote Breyer, in a dissent signed by all three of the liberals. “Yesterday, the Constitution guaranteed that a woman confronted with an unplanned pregnancy could (within reasonable limits) make her own decision about whether to bear a child, with all the life-transforming consequences that act involves. … But no longer. As of today, this court holds, a State can always force a woman to give birth, prohibiting even the earliest abortions.”

It is hard to overstate the impact of the court’s action. While the Supreme Court has in the past reversed long-standing decisions, most notably in cases involving race relations, the court has never granted a right and then erased it. 

In this case, the impact is also immediate. Thirteen states have so-called trigger laws that ban abortion, set to take effect upon Roe’s reversal. Other states have had pre-Roe abortion bans that could become active again, and some have post-Roe restrictions that are blocked by courts but could also take effect. In all, according to the Guttmacher Institute, which tracks reproductive health policy, 26 states are likely to ban or severely restrict abortion now that they are formally allowed to.

Reaction from those who support abortion rights was swift, although there is little they can do immediately to stop the wave of bans or restrictions. The House of Representatives has a majority of members who support abortion rights in at least some circumstances, but any legislation that would write abortion protections into federal law would lack the votes in the Senate to overcome a filibuster.

House Speaker Nancy Pelosi, in a statement released quickly after the decision, said: “Today, the Republican-controlled Supreme Court has achieved the GOP’s dark and extreme goal of ripping away women’s right to make their own reproductive health decisions. Because of Donald Trump, Mitch McConnell, the Republican Party and their supermajority on the Supreme Court, American women today have less freedom than their mothers.”
