Are class actions unconstitutional? Many people-defendants, conservative legislators, not to mention scholars at the American Enterprise Institute-would like them to be. For opponents of the class action, Martin Redish's book, Wholesale Justice, provides some of the most theoretically sophisticated arguments available. The book is a major contribution both to the scholarly literature on class actions and to the larger political debate about this powerful procedural device. The arguments it presents will surely be debated in courtrooms as well as classrooms.
