Alternatives to Traditional Adversary Methods of Presenting Scientific Expertise in the Legal System

Nancy Gertner and Joseph Sanders

The twin goals of any litigation are to arrive at a correct outcome and provide the parties with a sense that they were treated justly, even if they do not prevail. Adversarial proceedings are often perceived to be superior to inquisitorial proceedings with respect to the second goal but inferior with respect to the first. This is especially the case when proceedings involve expert testimony. In this essay, we discuss several relatively minor changes to typical adversarial processes that offer the potential of improving trial accuracy without disrupting the overall structure of adversarial proceedings. These changes include 1) alterations to the organization of the trial, including concurrent expert testimony; 2) alterations to the role of the jury, including taking notes, asking questions, and receiving written expert reports; and 3) formal expert witness codes of conduct designed to better arm experts to resist the adversarial pressures that lead to biased testimony.
