Challenging and Working with Expert Witnesses 

Webinar Faculty: Andre Vitale, Special Assistant Public Defender, Training Director

About the webinar: This presentation will address the challenges and potential pitfalls faced when a case involves the use of an expert witness, whether it is for the prosecution or the defense. In order to be effective a defense lawyer must retain and consult a defense expert every time the prosecution gives notice of intent to call an expert witness. We will discuss strategies for challenging the admissibility, the scope, and the weight of the prosecution’s proffered “expert” testimony. Part of this conversation will include the importance of challenging long admitted expert testimony under either Frye or Daubert, when developments in research reveal questions about reliability. Preparing for trial when a case involves an expert requires a great deal of commitment and research by the defense lawyer, even when a defense expert is expected to be called. This presentation will address the importance for the defense lawyer to become well versed in the discipline pertaining to the particular prosecution expert through research and investigation, even when a defense expert will likely testify. We will also discuss strategies and tips for working with a defense expert in order to make her testimony the most effective at trial.
