This concise casebook offers materials that are thorough yet brief, enabling coverage of all the major topics in a three- or four-credit format. The emphasis is decidedly on primary materials: well-edited principal cases, followed by notes that inform the student on important details and developments. Each chapter covers an article of the Federal Rules of Evidence. Within the chapters and sections, the materials generally follow the sequence of the Rules. The 8th edition covers all important recent developments, including federal and state court decisions interpreting the Rules, the Supreme Court's decision in Pena-Rodriguez v. Colorado (2017), and recent state developments concerning prior offenses in sex crime cases.
