The United States Supreme Court on Friday overturned the landmark 1973 Roe v. Wade decision, eliminating the constitutional right to an abortion that had stood for nearly five decades and leaving it up to the states to decide what restrictions - if any - to impose on that medical procedure.

The ruling by the conservative-majority high court in Dobbs v. Jackson Women's Health Organization upheld a 2018 Mississippi state law that banned most abortions after 15 weeks of pregnancy.

The Supreme Court ruled 6-3 to reverse lower-court rulings that had prevented enforcement of the Mississippi law and 5-4 to overturn Roe and the 1992 Planned Parenthood v. Casey decision that upheld the constitutional right to abortion.

"Abortion presents a profound moral question. The Constitution does not prohibit the citizens of each State from regulating or prohibiting abortion," reads the 79-page decision written by Associate Justice Samuel Alito and backed by fellow Associate Justices Clarence Thomas, Neil Gorsuch, Brett Kavanaugh and Amy Coney Barrett.

"Roe and Casey arrogated that authority. The Court overrules those decisions and returns that authority to the people and their elected representatives."
