Planned Parenthood of Southeastern Pennsylvania v. Casey

Case Overview

A joint opinion of Justices O'Connor, Kennedy, and Souter reaffirmed what it called Roe's essential holding while discarding the trimester framework for the undue burden standard, upholding most of Pennsylvania's abortion regulations but striking the spousal notification requirement. Its extended stare decisis analysis became the central battleground of Dobbs, which overruled both Roe and Casey in 2022.
