A Supreme Court decision / What is Roe V. Wade ?

Roe v. Wade is a landmark Supreme Court decision that legalized abortion across the United States. The 7-2 ruling was announced on Jan. 22, 1973. Justice Harry A. Blackmun, a modest Midwestern Republican and a defender of the right to abortion, wrote the majority opinion.

The ruling struck down laws in many states that had barred abortion, declaring that they could not ban the procedure before the point at which a fetus can survive outside the womb. That point, known as fetal viability, was around 28 weeks when Roe was decided. Today, most experts estimate it to be about 23 or 24 weeks.

Roe v. Wade created a framework to govern abortion regulation based on the trimesters of pregnancy. In the first trimester, it allowed almost no regulations. In the second, it allowed regulations to protect women’s health. In the third, it allowed states to ban abortions so long as exceptions were made to protect the life and health of the mother. In 1992, the court tossed that framework, while affirming Roe’s essential holding.

Individual states would be able to decide whether and when abortions would be legal. The practice would likely be banned or restricted heavily in about half of them, but many would continue to allow it. Thirteen states have so-called trigger laws, which would immediately make abortion illegal if Roe were overturned.
