This casebook is a classic in civil procedure. It contains lightly-edited cases with extensive explanatory notes, thereby teaching students how to read cases while learning doctrine. Some notes are historical and comparative, giving students a more nuanced understanding than can be obtained from simply studying current law. The book is accessible without sacrificing interest and complexity, providing a sophisticated understanding of civil procedure and the federal system. The eleventh edition has been thoroughly updated with fifteen new principal cases and notes on recent developments in personal jurisdiction, pleading, e-discovery, and class actions.
