"None of this is to say that Justice Blackmun did not delegate too much of the original design for the intellectual content for his opinions to law clerks. Notwithstanding my enormous affection and admiration for the justice, I think he did—and Garrow's discussion of how Roe v. Wade's trimester framework came into being helps illustrate the point. In my view, every justice should be deeply engaged in the original formulation of every significant doctrinal twist and turn of his or her opinions. On at least some occasions, Blackmun was not. And in this regard, a piece like Garrow's, despite its methodological failings, provides a useful counterpoint to the usual claptrap minimizing the role that clerks play in fashioning the law."
