William Saletan in Slate:
On Tuesday, the U.S. Supreme Court handed down a ruling on assisted suicide. On Wednesday, it handed down a ruling on abortion. As Justice Antonin Scalia has often observed, judges are supposed to stick to principles, not change them to suit personal preferences from one issue to the next. But evidently, that advice doesn’t apply to Scalia.
Scalia didn’t file a separate opinion in the abortion case, Ayotte v. Planned Parenthood of Northern New England. To find his principles of abortion jurisprudence, you have to go back to three prior cases: Webster v. Reproductive Health Services (1989), Planned Parenthood v. Casey (1992), and Stenberg v. Carhart (2000).
