The Court of Appeals for the 10th Circuit in United States v. Nacchio has recently reversed an insider trading conviction in the high profile criminal case, finding, in short, that the trial court improperly denied the defendant an opportunity to call an expert witness. The Court ordered a new trial. "The Court based its holding on the improper exclusion of expert testimony, specifically, an economic analysis of Nacchio's stock trading patterns," says Joseph Martini, a partner with Wiggin & Dana LLP and a member of the firm's White-Collar Litigation and Appellate Practice Groups. "From a review of the cases, it appears that issues concerning the introduction of expert testimony are coming up in more and more white collar criminal cases," he observes. Wiggin and Dana partner James Glasser also notes that during his tenure as former Chief of the Criminal Division of the U.S. Attorney's Office in Connecticut, "defense counsel in white collar cases often argued against federal charges by pointing to experts opinions on such issues as the application of complex accounting principles. These issues are now coming up at trial," says Glasser. Martini and Glasser are available to write or comment on expert testimony issues in white-collar criminal cases including the Nacchio trial.
