This pamphlet, which supports any classroom text, consists of the updated Federal Rules of Evidence (including new Rule 502), the California Evidence Code, and materials designed to aid in understanding, construing, and applying the FRE. It contains relevant legislative history and indicates where lawyers and judges should consider the interplay between case law and the rules. The text also includes the Evidence Map, a study aid presented in the format of a flowchart that helps law students understand the operations within particular rules and the relationships between different rules.
