Justice Sandra Day O'Connor, who died Friday at 93, was the sort of figure once familiar in American political and judicial life: a moderate Republican ready to look for compromise and common ground.
That led her to vote to uphold abortion rights, affirmative action and campaign finance regulations. Since she retired in 2006, replaced by the far more conservative Justice Samuel Alito, the Supreme Court has dismantled large parts of her legacy.
That is nowhere more apparent than in abortion rights.
O'Connor joined the controlling opinion in Planned Parenthood v. Casey, the 1992 decision that, to the surprise of many, reaffirmed the core of the constitutional right to abortion established in 1973 in Roe v. Wade.
To overrule Roe "under fire in the absence of the most compelling reason to re-examine a watershed decision," she wrote in a joint opinion with Justices Anthony Kennedy and David Souter, "would subvert the court's legitimacy beyond any serious question."
Last year, the court did overrule Roe, casting aside O'Connor's concern for precedent and the court's public standing. In his majority opinion in Dobbs v. Jackson Women's Health Organization, Alito wrote that Roe and Casey had "enflamed debate and deepened division."
