Roe v. Wade was a 1971 - 1973 landmark decision by the US Supreme Court. The court ruled that a state law that banned abortions (To save the mother) was unconstitutional. The ruling made abortion legal in many circumstances. The decision said that a woman's right to privacy extended to the fetus/unborn child she was carrying. In the view of the court, during the first trimester an abortion was no more dangerous than carrying the fetus/child full term.  The decision was 7-2, with Chief Justice Warren E. Burger and six other Justices voting for "Jane Roe", and Justices William Rehnquist and Byron White voting against it. 

The decision divided the nation and is still controversial today. People divided into pro-life and pro-choice groups. Pro-life supporters argue that the unborn baby has the same right to life as other people, and the government should intervene to protect it. Pro-choice supporters believe that the unborn baby is not the same as a person, and the woman has the right to choose what she wants to do with her body and that the government should not intervene. Roe was limited by a later decision called Webster v. Reproductive Health (1989), which allowed regulation of abortion in some cases.  Several states have considered  laws banning abortions altogether.

Background 
It began in Texas as a challenge against a law prohibiting any kind of abortion unless the mother's life was in danger. In 1970 a pregnant Texas woman, Norma McCorvey (alias Jane Roe), brought a lawsuit against Henry Wade, Dallas County District Attorney, in a Texas federal court. Alleging she was a single woman and pregnant, McCorvey wanted to terminate her pregnancy. She wanted it done safely by a doctor but said she could not afford to travel outside of Texas. She could not get a legal abortion in Texas because her life was not in danger. Her lawsuit claimed that the Texas law violated her right to privacy, protected by the First, Fourth, Fifth, Ninth, and Fourteenth Amendments. Roe added she sued "on behalf of herself and all other women" in the same situation. The case slowly made its way to the US Supreme Court. Meanwhile, McCorvey had her baby and placed it for adoption.

The majority decision 
In a 7-2 decision, the court held that a woman's right to an abortion was protected by her right to privacy under the Fourteenth Amendment. The decision allowed a woman to decide whether to keep or abort the fetus/unborn child during the first trimester. This affected the laws of 46 states. Justice Harry Blackmun wrote the majority opinion. “We … acknowledge our awareness of the sensitive and emotional nature of the abortion controversy, of the vigorous opposing views, even among physicians, and of the deep and seemingly absolute convictions that the subject inspires.” — Justice Blackmun (1973).

Dissenting opinion 
The dissenting opinion was written by Justice William Rehnquist. He objected to the majority decision giving several reasons. 
 He first pointed out there was no legitimate plaintiff in the case and that was a requirement to hear the case. A legitimate plaintiff would be a woman in her first trimester of her pregnancy at some point while the case was being tried. McCorvey (Jane Roe) did not fit that qualification and so the ruling had no application to the case.
 The court recognized a woman's right to abortion under the general "right to privacy from previous cases. But he argued, "A transaction such as this is hardly 'private' in the ordinary usage of the word."
 The majority opinion was vague on where exactly the right to privacy was located in the Constitution. Several amendments were mentioned, but none were specifically identified to contain the right to privacy. The word privacy is not found in the Constitution. 
 Additional problems include the court acting as a legislature in breaking pregnancy into three trimesters and outlining the permissible restrictions states may make. Rehnquist pointed out that 36 of the 37 states in 1868, when the Fourteenth Amendment was passed, had laws against abortion, including Texas. He wrote "...The only conclusion possible from this history is that the drafters did not intend to have the Fourteenth Amendment withdraw from the States the power to legislate with respect to this matter."

 Understanding Roe v. Wade 
 Right to privacy interpretation 
The basis for the "right to privacy" is a judicial interpretation that can be traced from an earlier case Griswold v. Connecticut (1965). In this landmark case, the Supreme Court ruled a Connecticut law prohibiting the use of contraceptives violated the right to privacy as found in the Constitution. However, the right to privacy is not directly mentioned in the Constitution. The Supreme Court has stated that the Right to Privacy is implied by several amendments. Beginning in 1923 the court interpreted the "liberty" guarantee in the Fourteenth Amendment as a broad right to privacy. Justice William O. Douglas stated the guarantees of the right to privacy had penumbras (implied rights) "formed by emanations (a flowing) from those guarantees that help give them life and substance."

 Trimester concept 
In its decision, the court used the three trimester framework of pregnancy. During the first trimester an abortion was safer for the mother than childbirth. The reasoning was that the decision whether to get an abortion at this stage should be left up to the mother to decide. Any law that interfered with abortions in the first trimester would be presumed to be unconstitutional. During the second trimester laws could regulate abortion only to protect the health of the mother. During the third trimester the unborn child was viable (able to live on its own outside the mother's womb). So laws could restrict or prohibit abortions except in cases where it was necessary to preserve the mother's health. This doctrine stood until 1992. In Planned Parenthood v. Casey'' (1992) the court changed from basing the legality of an abortion on trimesters to basing it on fetal viability.
