The Constitution fixes no number of Justices and never explicitly grants the Court judicial review. The episode sets Hamilton's Federalist No. 78, with its promise of a 'least dangerous branch,' against the Anti-Federalist 'Brutus,' who warned that life-tenured judges would expand their own power beyond any check. One was a ratification argument; the other reads like a prophecy.
Who wrote the Brutus essays is not settled; Robert Yates is the likely but uncertain candidate. Historians also dispute how sweeping the Framers meant judicial review to be, and whether Brutus was vindicated.
