On 1 July 1976, the US Supreme Court decided in the case Planned Parenthood v. Danforth that provisions of a Missouri law regulating abortion care were unconstitutional. That law, House Bill 1211, restricted abortion care by requiring written consent for each abortion procedure from the pregnant woman as written consent of the woman’s husband if she was married, or the written consent of her parents if she was unmarried and younger than eighteen. House Bill 1211 also required that physicians make efforts to preserve the lives of aborted fetuses. Following the passage of House Bill 1211 in 1974, two physicians and Planned Parenthood of Central Missouri challenged the law. Following the decisions by several lower courts, the US Supreme Court ruled on the case. The US Supreme Court struck down parts of a law that violated the US Constitution and the prior court case Roe v. Wade, and in doing so, they expanded access to abortion care in the US.

On 2 July 1979, the United States Supreme Court decided Bellotti v. Baird, ruling that a Massachusetts law that prohibited minors from obtaining abortions without parental consent was unconstitutional. That law prohibited minors from receiving abortions without permission from both of their parents or a superior court judge. Under that law, if one or both of the minor’s parents denied consent, the minor could petition a superior court judge who would determine whether the minor was competent enough to make the decision to abort on her own. In addition to judging the minor’s competency, a superior court judge could also determine whether the abortion was in the minor’s best interest. The Supreme Court upheld a lower court’s decision and ruled that the existing Massachusetts law was unconstitutional. The Supreme Court’s ruling on Bellotti v. Baird affirmed that minors had the right to choose an abortion and that the decision to abort was personal and could not be overridden or vetoed by a third party.

Horatio Robinson Storer was a surgeon and anti-abortion activist in the 1800s who worked in the field of women’s reproductive health and led the Physicians’ Crusade Against Abortion in the US. Historians credit Storer as being one of the first physicians to distinguish gynecology, the study of diseases affecting women and their reproductive health, as a separate subject from obstetrics, the study of pregnancy and childbirth. Storer was one of the first physicians to successfully perform a Caesarian section, or the removal of the fetus through a surgical incision, followed by the removal of the woman’s uterus, a procedure which would later be known as Porro’s operation. Storer was also an anti-abortion activist who believed that public attitudes toward abortion were too relaxed and that the laws did not effectively punish what he deemed to be the criminal act of abortion. Historians credit Storer with leading the Physicians’ Crusade Against Abortion, which they consider largely responsible for the increase in laws criminalizing abortion in the late 1800s.

Arizona Revised Statutes 13-3603 (1864), or ARS 13-3603, was a territorial law enacted in 1864 before Arizona was granted statehood that banned abortion in any circumstances except when the mother’s life is at risk. The law remained in place even after Arizona was granted statehood in 1912 and reflected the nineteenth- and twentieth-century legal approach to abortion across the United States. However, the US Supreme Court Case Roe v. Wade (1973), hereafter Roe, overturned the statute by establishing a federal constitutional right to abortion, and made ARS 13-3603 unenforceable. The law has since been significant in legal discourse following the federal law Dobbs v. Jackson Women’s Health Organization (2022), hereafter Dobbs, which overturned Roe and allowed state governments to re-enforce pre-existing abortion laws, including ARS 13-3603. By allowing states to reinstate pre-existing abortion restrictions, the Dobbs decision enabled the territorial law ARS 13-3603 to re-enter legal discussions after Dobbs.

Arizona Senate Bill 1164 (2022), or SB 1164, prohibited abortions after fifteen weeks of pregnancy except when necessary to protect the life or health of the mother. The Arizona Senate and the Arizona House of Representatives passed SB 1164, and then-governor Douglas Ducey signed the bill into law on 30 March 2022. The passage of SB 1164 reinforced the state’s ability to regulate abortions following the US Supreme Court decision Dobbs v. Jackson Women’s Health Organization (2022) decision, hereafter Dobbs, which overturned the federal law Roe v. Wade (1973), hereafter Roe. Roe had established abortion as a constitutional and federal right and prohibited states from banning abortions before fetal viability. Roe defined fetal viability as the point when the fetus has a chance of surviving outside the womb without extreme medical help. Dobbs returned the regulatory rights to the states. Arizona’s SB 1164 has helped shape the legal framework concerning reproductive rights in the state by prohibiting abortions after fifteen weeks and replaced Arizona’s previous 1864 law titled Arizona Revised Statutes 13-3603, or ARS 13-3603.
