Book excerpt: Stuart Banner's The Most Powerful Court in the World is an authoritative history of the United States Supreme Court from the Founding era to the present. Not merely a history of the Court's opinions and jurisprudence, it is also a rich account of the Court in the broadest sense--of the sorts of people who become justices and the methods by which they are chosen, of how the Court does its work, and of its relationship with other branches of government. Rather than praising or criticizing the Court's decisions, Banner makes the case that one cannot fully understand the decisions without knowing about the institution that produced them.
