"The title of this book, What Roe v. Wade Should Have Said, might suggest that changing the language of the opinion might have changed history. That may or may not be the case. The exact language of a decision may matter much less than most people (and most legal scholars) think. Most Americans do not read Supreme Court opinions and have only the vaguest idea of their contents. Moreover, whatever the original language, no decision is immune from subsequent revision, especially a controversial one like Roe v. Wade. Judges and Justices reshape and transform older decisions to conform with current concerns. The meaning of Roe was transformed repeatedly over time, and substantial features of Roe were jettisoned and replaced by the 1992 decision in Planned Parenthood of Southeastern Pennsylvania v. Casey."
