Two local judges have made the unconventional move of denying Dr. Derek Duke, a Las Vegas neurosurgeon who earns about $1 million annually by serving second opinions in lawsuits, the chance to testify as an expert witness in two cases. On March 20, after 11 days of hearings, Timothy Williams, District Judge, ordered that Duke cannot testify in Mitch Wilson’s personal injury case as a 35-page opinion mentioned that “Dr. Duke’s medical opinions are personal and his methodology unreliable. The Court further finds that Dr. Duke’s medical opinions rely heavily on speculation and other irrelevant factors.”
