What case did the US Supreme Court rule that the decision to terminate a pregnancy must be left up to the woman with some restrictions applying as the pregnancy advances through three trimesters?

Answer 1

Roe v Wade established abortion rights.

Answer 2

The case you are referring to is Roe v. Wade (1973). In this landmark decision, the US Supreme Court held that a woman has a constitutional right to have an abortion, but the right is not absolute. The court recognized that the state has an interest in protecting the potential life of the fetus, and so the right to an abortion is subject to strict scrutiny and can be regulated by the state in certain circumstances as the pregnancy progresses.
