The sixth edition of this successful casebook continues the authors' commitment to providing professors and their students with the tools to address both foundational questions and cutting edge procedural issues in a practical way that is attuned to today's legal practice. It contains an expanded treatment of the increasingly important topic of pleading practice, and additional emphasis on electronic discovery issues. It also offers carefully edited versions of recent Supreme Court cases like Ashcroft v. Iqbal and J. McIntyre Machinery, Ltd. v. Nicastro, along with textual and note material to identify and highlight the critical issues. The class-action section contains presentations on Wal- Mart v. Dukes and the key issues raised by the Court's decisions on class-action waivers in arbitration clauses that are appropriate for first-year students. Throughout, the material has been updated and revised to focus on the critical issues of 21st century practice. As with prior editions, the authors will provide a thorough Teachers' Manual, which they will supplement with annual Teachers' Updates to keep teachers entirely up-to-date.
