Planned Parenthood v. Casey modified Roe's framework by adopting which standard for abortion restrictions?

• A. Introduced the undue burden standard for abortion restrictions.
• B. Abolished Roe's framework entirely.
• C. Prohibited abortion in all states.
• D. Instituted a trimester framework for abortion.

Answer: (A)

The key idea is how abortion restrictions are judged after Casey. Casey kept a woman’s right to abortion before viability but changed how courts review laws by introducing the undue burden standard. Under this standard, a law is unconstitutional if its purpose or effect places a substantial obstacle in a woman’s path to obtaining an abortion before fetal viability. Laws that create only minor obstacles or that protect legitimate interests without blocking access are allowed. After viability, states may regulate or even prohibit abortion, with allowances for the mother’s life or health. Casey thus introduced the undue burden approach, rather than returning to Roe’s trimester framework, abolishing Roe, or banning abortion nationwide.
