'In this meticulous study Robert Steinfeld examines how the distinctive US form of constitutional review emerged from a background tradition in which legislatures and executives assessed constitutionality in their regular work. Combining institutional, political, and intellectual history, Professor Steinfeld shows how the transformation was both rapid and strongly contested. Seeing judicial review as part of a conservative counterrevolution against the democratic excesses of post-Revolutionary legislatures, this is an important new contribution to long-standing discussions about judicial review in the United States.'
