The anti-jury impeachment rule, contained in Federal Rule of Evidence 606(b) and state counterparts, is a rule preventing the admission of jury testimony or statements in connection with an inquiry into the validity of the verdict, subject to certain exceptions. Through a series of cases and hypotheticals drawn from actual cases, this chapter gives readers a roadmap for how to address any jury impeachment issue in practice.
