The Eighth Edition of this classic casebook includes numerous revisions to capture major changes in the law, including to the doctrine of justiciability, to the Supreme Court's emergency docket, and to the role of equity in federal courts. The book's depth of coverage and intellectual rigor remain unrivaled. In addition, several of the chapters have been consolidated and reorganized to make the materials easier to teach and more accessible to students. Many new introductory and explanatory notes help to frame the key issues raised by the materials. Moreover, the editors' judicious revision and trimming of older material will permit assignments of manageable length, without sacrificing the scholarly comprehensiveness that has always been the Hart & Wechsler hallmark.
