This long-popular casebook has two main distinguishing attributes. First, because students benefit from sustained engagement with Supreme Court opinions, pivotal cases are edited less substantially than in many other books. Second, because Constitutional Law is an argumentative practice situated in ongoing debates, this edition follows its predecessors in exposing students to diverse perspectives in the Notes and Questions that follow most principal cases. Instructors will especially like the illuminating and provocative extracts from the literature that accompany important new cases. In preparing the new edition, the editors have made judicious cuts to enable the addition of new material and have thoroughly revised several chapters to reflect developments in the case law.
