This document provides guidance on delivering effective opening statements in a mock trial. It emphasizes that the opening statement is important for establishing a clear theory of the case and themes to guide the jury. The opening should tell a story that personalizes the parties and makes the events vivid and dramatic. It should walk the jury through a chronological retelling of key events and anticipate weaknesses in the other side's case. An effective opening introduces the parties, describes the scene and issues, explains the basis for a verdict of guilt or non-guilt, and concludes by asking the jury for the desired verdict. It focuses on people rather than problems and keeps the presentation simple, logical, and concise.
