On June 24, 2022, the Supreme Court (SCOTUS) overturned Roe v. Wade, the 1973 landmark decision that affirmed a constitutional right to abortion, and Planned Parenthood of Southeastern Pennsylvania v. Casey (1992), which reaffirmed that right. Dobbs v. Jackson Women's Health Organization is the case that led to the reversal of Roe and Casey. SCOTUSblog provides extensive coverage of Dobbs, with texts of proceedings and orders from March 2020 to the 6/24 decision, along with multiple articles. The Roe and Casey decisions can also be found at Justia.
Justice Alito wrote the majority opinion in Dobbs, which was joined by Justices Thomas, Gorsuch, Kavanaugh, and Barrett. Chief Justice Roberts concurred (p. 136) in the judgment, but did not support overturning Roe. Justices Breyer, Sotomayor, and Kagan dissented; their minority opinion starts at page 148 of the decision.
