Experts

The expert-witness chapter ties together qualification, the law of expert testimony (Daubert, Kumho, Frye), direct examination of experts, expert opinion structure, and expert cross-examination. It explains the gatekeeping role of judges under FRE 702, walks through qualification questions, opinion outlines and hypotheticals, treatise use, and the strategic choice between supportive and discrediting cross. The integrated treatment of doctrine and craft — students see the rule, the foundation question that satisfies it, and the cross-examination that exploits a weakness — makes the chapter particularly useful in a course that pairs evidence with trial advocacy, or in an expert-witness clinic where students must qualify and examine retained experts in mock proceedings.
