The Disappointing History Of Science In The Courtroom: Frye, Daubert, And The Ongoing Crisis Of “Junk Science” In Criminal Trials, Jim Hilbert

Faculty Scholarship

Twenty-five years ago, the Supreme Court decided one of the most important cases concerning the use of science in courtrooms. In Daubert v. Merrell Dow Pharmaceuticals , the Court addressed widespread concerns that courts were admitting unreliable scientific evidence. In addition, lower courts lacked clarity on the status of the previous landmark case for courtroom science, Frye v. United States. In the years leading up to the Daubert decision, policy-makers and legal observers sounded the alarm about the rise in the use of "junk science" by so-called expert witnesses. Some critics went so far as to suggest that American businesses …

Judicializing History: Mass Crimes Trials And The Historian As Expert Witness In West Germany, Cambodia, And Bangladesh, Rebecca Gidley, Mathew Turner

Genocide Studies and Prevention: An International Journal

Henry Rousso warned that the engagement of historians as expert witnesses in trials, particularly highly politicized proceedings of mass crimes, risks a judicialization of history. This article tests Rousso’s argument through analysis of three quite different case studies: the Frankfurt Auschwitz trial; the Extraordinary Chambers in the Courts of Cambodia; and the International Crimes Tribunal in Bangladesh. It argues that Rousso’s objections misrepresent the Frankfurt Auschwitz trial, while failing to account for the engagement of historical expertise in mass atrocity trials beyond Europe. Paradoxically, Rousso’s criticisms are less suited to the European context that represents his purview, and apply more …

Neuroscience In Forensic Contexts: Ethical Concerns, Stephen J. Morse

Faculty Scholarship at Penn Carey Law

This is a chapter in a volume, Ethics Challenges in Forensic Psychiatry and Psychology Practice, edited by Ezra E. H. Griffith, M.D. and to be published by Columbia University Press. The chapter addresses whether the use of new neuroscience techniques, especially non-invasive functional magnetic resonance imaging (fMRI) and the data from studies employing them raise new ethical issues for forensic psychiatrists and psychologists. The implicit thesis throughout is that if the legal questions, the limits of the new techniques and the relevance of neuroscience to law are properly understood, no new ethical issues are raised. A major ethical lapse …

Implicit Bias In Daily Perceptions And Legal Judgments, Keith B. Maddox, Samuel R. Sommers

University of Michigan Journal of Law Reform

In today’s demonstration, we explored the audience’s positive and negative associations with blacks and whites. The demonstration is an adaptation of the Implicit Association Test (www.projectimplicit.net), a computer-based task designed to explore mental connections between various concepts. Participants were presented with a list of concepts (stereotypically black and white names, pleasant and unpleasant concepts) in a column down the middle of a screen along with the response categories (black/white or Pleasant/Unpleasant) along the left and right sides. When reading a word, participants were asked to categorize it by slapping the knee (left or right) that corresponds to the category displayed …

New Rules Of War In The Battle Of The Experts: Amending The Expert Witness Disqualification Test For Conflicts Of Interest, Nina A. Vershuta

Brooklyn Law Review

In civil litigation, the big business of retaining experts has raised concerns about the integrity of the adversarial process and undermined the role that expert testimony plays at trial. Due to a rising demand for expert testimony, it is common for the same expert to testify for opposing clients. When a client hires an expert who has been previously retained by that client’s adversary, a conflict of interest arises. Such experts may share confidential information with their new client to the detriment of the former client—triggering the expert disqualification test for conflicts of interest. Most state and federal courts do …

Jurors' Evaluations Of Expert Testimony: Judging The Messenger And The Message, Sanja Kutnjak Ivkovic, Valerie P. Hans

Valerie P. Hans

Jurors are laypersons with no specific expert knowledge, yet they are routinely placed in situations in which they need to critically evaluate complex expert testimony. This paper examines jurors' reactions to experts who testify in civil trials and the factors jurors identify as important to expert credibility. Based on in-depth qualitative analysis of interviews with 55 jurors in 7 civil trials, we develop a comprehensive model of the key factors jurors incorporate into the process of evaluating expert witnesses and their testimony. Contrary to the frequent criticism that jurors primarily evaluate expert evidence in terms of its subjective characteristics, the …

Breaking The Ice: How Plaintiffs May Establish Premises Liability In "Black Ice" Cases Where The Dangerous Condition Is By Definition Not Visible Or Apparent To The Property Owner, Hon. Mark Dillon

Hon. Mark C. Dillon

Plaintiffs that are injured as a result of encounters with "black ice," as distinguished from regular ice, face peculiar difficulties in establishing liability against property owners for the dangerous icy conditions on their premises. Black ice results from a unique process under certain conditions by which air bubbles are expelled from water during the freezing process, rendering the ice virtually invisible to the naked eye. Property owners therefore are not typically on actual or constructive notice of black ice conditions as to become subject to the legal requirement of undertaking measures to remedy the conditions. This article explores the law …

An Economic Analysis Of Fact Witness Payment, Eugene Kontorovich, Ezra Friedman

Faculty Working Papers

In this paper we discuss the disparate treatment of perceptual (''fact'') witnesses and expert witnesses in the legal system. We highlight the distinction between the perceptual act of witnessing and the act of testifying, and argue that although there might be good reasons to regulate payments to fact witnesses, the customary prohibition on paying them for their services is not justified by reference to economic theory. We propose considering a court mediated system for compensating fact witnesses so as to encourage witnessing of legally important events.We construct a simple model of witness incentives, and simulate the effects of several possible …

Another "Straightforward Application": The Impact Of Melendez-Diaz On Forensic Testing And Expert Testimony In Controlled Substance Cases, John Wait

Campbell Law Review

Part I of this Article will analyze Melendez-Diaz with a focus on extracting indicators within the opinion that lend guidance as to how the opinion could be extended to Bullcoming and to expert testimony based on forensic reports in controlled substance cases. Part II will provide an overview of the tests utilized by the SBI to determine the nature and quantity, if any, of suspected controlled substances with the goal of ascertaining who, under Melendez-Diaz, should be subject to confrontation. Part III will provide a prediction of the outcome in Bullcoming. Finally, Part IV will review the pending cases from …

Blind Expertise, Christopher Robertson

Faculty Scholarship

The United States spends many billions of dollars on its system of civil litigation, and expert witnesses appear in a huge portion of cases. Yet litigants select and retain expert witnesses in ways that create the appearance of biased hired guns on both sides of every case, thereby depriving factfinders of a clear view of the facts. As a result, factfinders too often arrive at the wrong conclusions, thus undermining the deterrence and compensation functions of litigation. Court-appointment of experts has been widely proposed as a solution, yet it raises legitimate concerns about accuracy and has failed to gain traction …

Prosecutors, Ethics, And Expert Witnesses, Paul C. Giannelli, Kevin C. Mcmunigal

Faculty Publications

Commentators who have examined the DNA exonerations have noted the disturbing role that prosecutors have played in these wrongful convictions. Another significant contributor to these miscarriages of justice is the misuse of expert testimony, a third of the cases according to some sources. This Article examines the intersection of these two factors - the prosecutor's role in using and presenting expert testimony.

Prosecutorial misconduct may occur during most stages of a trial, beginning with the selection of witnesses, including the improper "shopping" for experts. Additional abuses occur when prosecutors fail to abide by rules governing the pretrial disclosure of scientific …

Gatekeeping After Gilbert: How Lawyers Should Address The Court's New Emphasis, Brian Benner, Ronald L. Carlson

Popular Media

In the world of modern trials, expert witnesses are the coin of the realm. Lawyers know that most of the time, experts are case-breakers. Their demeanor, knowledge, and presentation ability are key qualities. Accordingly, their persuasive effect on modern lay jurors makes it incumbent on judges to ensure that an expert's opinions are appropriately directed. That means not allowing an economist to testify about the medical dynamics of bone disease, for example.

Reconsidering The Medical Expert Witness System, Yunwei Jiang

LLM Theses and Essays

The expert witness is indispensable in a medical malpractice case. However, there are three main defects in the currently existing expert witness system. One is incompetence of expert witnesses. Another is professional negligence of expert witnesses. The other is dishonesty of expert witnesses. To make the expert witness system more efficient, this article examines currently existing rules and offers some proposals regarding the three issues. For the first one, the suggestion of this article is to rely on the standards of expert qualification and admitting expert testimony. For the second one, this article distinguishes expert witnesses from lay witnesses, and …

Expert Testimony On Fingerprints: An Internet Exchange, Richard D. Friedman, David H. Kaye, Jennifer Mnookin, Dale Nance, Michael Saks

Articles

In United States v. Llera Plaza, 188 F. Supp. 2d 549 (E.D. Pa. 2002), a federal district initially limited expert opinion testimony on fingerprint identifications because the government was unable to show that such identifications were sufficiently valid and reliable under Federal Rule of Evidence 702. Then, the court withdrew the opinion. This article reproduces an exchange of notes on the initial opinion submitted by five law professors.

The Other Shoe Drops: Minnesota Rejects Daubert, Peter B. Knapp

Faculty Scholarship

In 1991, the United States Supreme Court handed decided Daubert v. Merrell Dow Pharmaceuticals, Inc., rejecting the long-standing federal test for the admissibility of scientific testimony articulated in Frye v. United States. Unlike many states, however, which embraced Daubert within years--or even months--of the federal decision, Minnesota declined to make Daubert the law of the jurisdiction. In a pair of cases decided in 2000, Goeb v. Tharaldson and Sentinel Mgmt. v. Aetna Casualty & Surety, the court held that Minnesota would retain the general acceptance test. The court's rejection of Daubert can be read as an attempt to give the …

Scientific Evidence And The Ethical Obligations Of Attorneys, Michael J. Saks

Cleveland State Law Review

This article considers the question: "What are the legal and ethical responsibilities of attorneys when offering scientific expert evidence to courts?" To a lesser extent it considers the responsibilities of attorneys to challenge such evidence when proffered and the ethical dimensions of the working relationship of lawyers and experts. Although the most prominent discussions of such issues have concerned so-called junk science in civil trials, the legal context upon which this article will focus is the criminal trial, where dubious science is more common, less questioned, and has even become institutionalized. The rules and practices of civil cases are provided …

Detection Of Deception: The Case Of Handwriting Expertise, Samuel R. Gross

Articles

The basic method of handwriting identification is the same now as it was in Twelfth Night: to compare the questioned writing with other writings by the supposed writer. This can be done from memory if (like Malvolio) one is already familiar with the claimed author's handwriting, or by examining the questioned document together with known samples. It's a simple, obvious task. Any person-certainly any literate person--can have a go at it. The claim by handwriting experts, now and in the past, is equally simple: We can do it better.
