Step-by-step explanation:
Planned Parenthood v. Casey (1992) Summary
In Planned Parenthood v. Casey (1992), the justices of the Supreme Court rejected Roe v. Wade's trimester framework and introduced the undue burden test for determining the constitutionality of state abortion regulations. The undue burden test allows for certain state restrictions on abortion procedures prior to fetal viability, provided those restrictions do not pose substantial obstacles to women seeking an abortion. This decision upheld the constitutionality of several Pennsylvania state regulations including a required waiting period, parental consent, and informed consent provisions, while striking down the spousal notification requirement as an undue burden.
The Casey decision has been significant in shaping the landscape of abortion rights in the United States. It has allowed states to enact a variety of restrictions that do not constitute an undue burden, thereby impacting access to abortion services, especially in certain regions. The decision moved away from the more rigid trimester-based approach established by Roe v. Wade, allowing for more state discretion earlier in pregnancy and reinforcing the ongoing legal and social debates surrounding abortion rights.
