I have been less enthusiastic about the appearance of Greenburg’s book, but I did not know the “inside story” of the conversations that propelled Justice O’Connor to retire when she did. This is the sort of thing that books like this are useful for. And if it is true that William Rehnquist effectively pushed Sandra Day O’Connor out the door to a retirement she would otherwise have delayed, then this fact would count as the last great service he did for his country.
