Here, the Court found that Roe's case was not moot—even though she had already had her child—because pregnancy is something that can be repeated; however, when suits regarding legal injuries suffered in pregnancy reach the relevant court, the pregnancy is usually completed.
Regarding Fundamental Rights
The 14th Amendment's Substantive Due Process protection of the "right to privacy" is broad enough to include the decision to have an abortion.
Abortion was considered a fundamental right, meaning any restriction had to pass strict scrutiny.
Introduced a trimester-based framework:
1st Trimester: the State could not regulate abortion at all; the choice was purely between a woman and her doctor.
2nd Trimester: States could regulate abortion only to protect the mother's health.
3rd Trimester: Once the baby reached viability, States could regulate or ban abortion, provided that they allowed exceptions for the mother's life/health.
Viability—the ability to survive outside of the womb.
