Which case replaced Roe's framework with the 'undue burden' standard for abortion regulations?

• A. Dobbs v. Jackson Women's Health (2022)
• B. Planned Parenthood v. Casey (1992)
• C. Lawrence v. Texas (2003)
• D. Roe v. Wade (1973)

Answer: (B)

The key idea is how abortion regulations are reviewed by the Court. Planned Parenthood v. Casey changed Roe’s approach by discarding the old trimester framework and introducing the undue burden standard. It held that a pre-viability abortion restriction is unconstitutional only if it places a substantial obstacle in a woman’s path to obtain an abortion. In practice, states may regulate abortion before viability as long as the regulation does not impose an undue burden; after viability, the state’s interest in potential life allows more regulation. This shift preserved the right to abortion but set a different test for evaluating laws. The other options don’t fit: Roe established the earlier framework that Casey overruled; Dobbs later overturned Roe’s framework; Lawrence concerns privacy in a different area.
