An idea of an ethics code appears to have riven the Supreme Court, marking the folly of an effort to bind the Nine that was ill-conceived from the get-go. For the court’s critics —  largely Democrats ruing Roe v. Wade — no code, not even Hammurabi’s, would be draconian enough to hem in a court with a conservative tilt. That makes it all the more shocking that the liberal justices have joined this effort to mortgage the court’s independence.
