In the 1989 case Webster v. Reproductive Health Services, the US Supreme Court upheld the constitutionality of a Missouri law regulating abortion care. The Missouri law prohibited the use of public facilities, employees, or funds to provide abortion counseling or services. The law also placed restrictions on physicians who provided abortions. A group of physicians affected by the law challenged the constitutionality of certain sections of it. The US federal district court that first heard the case ruled many of the challenged sections of the law unconstitutional. The Missouri attorney general then appealed the case to an US federal appeals court and eventually to the US Supreme Court in Washington, D.C. In a five to four decision, the US Supreme Court overturned the decisions of the lower federal courts, ruling that it was constitutional to prohibit public funds, facilities, and employees from providing abortion care. In doing so, the Supreme Court upheld a state law that limited women’s access to abortions and established a precedent that states could apply restrictions to abortion care.

In the 1990 case Hodgson v. Minnesota, the US Supreme Court in Washington, D.C., upheld Minnesota statute 144.343, which required physicians to notify both biological parents of minors seeking abortions forty-eight hours prior to each procedure. The US Supreme Court determined that a state could legally require physicians to notify both parents of minors prior to performing abortions as long as they allowed for a judicial bypass procedure, in which courts could grant exceptions. The Supreme Court’s decision in Hodgson v. Minnesota allowed for the enforcement of Minnesota statute 144.343, which changed minors’ abilities to access abortions in Minnesota by requiring parental notification by a physician forty-eight hours prior to each abortion.

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.
