On October 26, Chapman University Dale E. Fowler School of Law welcomed UCLA Law Dean Jennifer L. Mnookin as a featured guest in the 2015-2016
Chapman Dialogue Lecture Series
. Her presentation entitled “
Modular, Made-in-Advance Expert Testimony: Opportunities and Obstacles
” was followed by a discussion with Fowler School of Law Professor Mario Mainero.

UCLA Law Dean Jennifer L. Mnookin speaking at Podium
Dean Mnookin identified a unique problem in the accessibility of emerging psychological expert testimony regarding eyewitness testimony and proposed a simple but path-breaking solution to ensure that more criminal defendants have an opportunity to present such testimony when it is relevant. Dean Mnookin explained that the single most prevalent issue in wrongful conviction cases is erroneous eyewitness testimony. Acknowledging that eyewitness testimony will often have value as providing accurate, reliable and legitimate grounds for conviction, such testimony can nonetheless sometimes be flawed. Increasingly, courts are allowing experts to testify about what social science research shows regarding when certain types of eyewitness testimony might raise reliability concerns, she explained. According to Dean Mnookin, such concerns especially arise regarding lineup designs, cross-racial identification, and the identified errors caused by “weapons focus” where witness observations might get skewed because of the anxiety involved with the presence of a weapon at a crime scene. She contends that experts can add some information to assist the factfinder in determining whether an eyewitness may be more or less believable in light of these scientific studies. Such expert testimony, however, is offered rarely because retaining such experts – if it’s possible to find one given the narrow pool of those specializing in the area – is very expensive for defendants.

So, Dean Mnookin’s proposed solution to this accessibility issue is to use technology to solve the problem where a neutral organization would produce “made in advance” evidentiary video modules structured like live testimony with real experts, a real defense attorney and a real prosecutor playing out the direct and cross examination on these social science issues. It works, according to Dean Mnookin, because in the vast majority of cases where this type of testimony is relevant, such evidence is not case-specific.

Dean Mnookin carefully explained many of the details of her proposed module system and defended it against anticipated concerns including hurdles that exist in the evidentiary code. Professor Mainero, one of Chapman’s experts on evidence law, presented challenging questions including examining whether the rules are necessary given the availability of other means to discredit eyewitnesses and identified possible concerns regarding practical and legal feasibility. Professor Mainero’s comments and questions engaged with the issue in a way that allowed the dialogue to proceed toward further explanations of the problem and further identification of the steps that must be taken, including potential changes to the evidence codes, before Dean Mnookin’s proposal could receive widespread adoption.
