Overview
Theodore Thomas, Director of Professional Development and Wendy Steiner, Assistant Public Defender, Law Office of the Cook County Public Defender
Details
Expert witnesses can play a critical role in developing and presenting a defense, but effective expert work requires much more than simply identifying and retaining the right person. This practical session will walk Defenders through the entire process of working with an expert which will include the initial decision to seek expert assistance through preparation for testimony at trial.
Presenters will discuss how to identify and approach potential experts, frame the issues and questions you want an expert to explore, determine what discovery and other information to provide, and establish clear expectations for communication, deadlines, and deliverables. The session will also address the importance of communicating with an expert before a report is finalized, reviewing draft findings when appropriate, and ensuring that the attorney understands both the strengths and potential limitations of the expert’s conclusions.
The presentation will also explore the different ways experts can assist a defense team, including consultation, mitigation, case development, trial testimony, and the rules of evidence that are vital when putting on an expert. Using actual case examples, presenters will discuss both successful and unsuccessful experiences working with experts, lessons learned, and practical strategies for incorporating expert evidence into the theory and presentation of a case.
