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 …

How Daubert And Its Progeny Have Failed Criminalistics Evidence And A Few Things The Judiciary Could Do About It, David H. Kaye

Journal Articles

A recent report of the President’s Council of Advisors on Science and Technology questioned the validity of several types of criminalistics identification evidence and recommended “a best practices manual and an Advisory Committee note, providing guidance to Federal judges concerning the admissibility under Rule 702 of expert testimony based on forensic feature-comparison methods.” This article supplies information on why and how judicial bodies concerned with possible rules changes—and courts applying the current rules—can improve their regulation of criminalistics identification evidence. First, it describes how courts have failed to faithfully apply Daubert v. Merrell Dow Pharmaceutical’s criteria for scientific validity to …

Crossing The Line: Daubert, Dual Roles, And The Admissibility Of Forensic Mental Health Testimony, Sara Gordon

Scholarly Works

Psychiatrists and other mental health professionals often testify as forensic experts in civil commitment and criminal competency proceedings. When an individual clinician assumes both a treatment and a forensic role in the context of a single case, however, that clinician forms a dual relationship with the patient—a practice that creates a conflict of interest and violates professional ethical guidelines. The court, the parties, and the patient are all affected by this conflict and the biased testimony that may result from dual relationships. When providing forensic testimony, the mental health professional’s primary duty is to the court, not to the patient, …

Cell Phones, Brain Cancer, And Scientific Outliers In Murray V. Motorola, David H. Kaye

Journal Articles

Pending before the District of Columbia's highest court in a case asking whether cell phones can cause cancer is whether to replace the jurisdiction's venerable Frye standard for reviewing the admissibility of scientific evidence with the approach adopted by the U.S. Supreme Court in Daubert v. Merrell Dow. The author analyzes one aspect of the two evidentiary standards that leads him to question the trial judge's suggestion in Murray v. Motorola that adopting the Daubert perspective would allow greater leeway in excluding the plaintiff's evidence.

Death By Daubert: The Continued Attack On Private Antitrust, Christine P. Bartholomew

Journal Articles

In 2011, with five words of dicta, the Supreme Court opened Pandora’s box for private antitrust enforcement. By suggesting trial courts must evaluate the admissibility of expert testimony at class certification, the Court placed a significant obstacle in the path of antitrust class actions. Following the Supreme Court’s lead, most courts now permit parties to bring expert challenges far earlier than the traditional summary judgment or pretrial timing. Premature rejection of expert testimony dooms budding private antitrust suits — cases that play an essential role in modern antitrust enforcement. The dangers for private antitrust plaintiffs are compounded by the Court’s …

When Truth Cannot Be Presumed: The Regulation Of Drug Promotion Under An Expanding First Amendment, Christopher Robertson

Faculty Scholarship

The Food, Drug, and Cosmetic Act (FDCA) requires that, prior to marketing a drug, the manufacturer must prove that it is safe and effective for the manufacturer’s intended uses, as shown on the proposed label. Nonetheless, physicians may prescribe drugs for other “off-label” uses, and often do so. Still, manufacturers have not been allowed to promote the unproven uses in advertisements or sales pitches.

This regime is now precarious due to an onslaught of scholarly critiques, a series of Supreme Court decisions that enlarge the First Amendment, and a landmark court of appeals decision holding that the First Amendment precludes …

Reliable Science: Overcoming Public Doubts In The Climate Change Debate, Michelle S. Simon

Elisabeth Haub School of Law Faculty Publications

This article will consider the case for instituting a domestic agency that would evaluate the findings from Intergovernmental Panel on Climate Change (IPCC) assessments to improve the credibility and legitimacy of those claims and conclusions for multiple purposes. The proposed agency would consider the robustness of an assessment's conclusions by construing the evidence through the lens of Daubert rather than Frye. Part I will outline the public debate about climate science-what the debate is about and why it exists. Part II will examine the current role of the IPCC-what it is and why it has not been successful in legitimating …

Liar, Liar, Jury's The Trier? The Future Of Neuroscience-Based Credibility Assessment And The Court, John B. Meixner Jr.

Scholarly Works

Neuroscience-based credibility-assessment tests have recently become increasingly mainstream, purportedly able to determine whether an individual is lying to a certain set of questions (the Control Question Test) or whether an individual recognizes information that only a liable person would recognize (the Concealed Information Test). Courts have hesitated to admit these tests as evidence for two primary reasons. First, following the general standard that credibility assessment is a matter solely for the trier of fact, courts exclude the evidence because it impinges on the province of the jury. Second, because these methods have not been rigorously tested in realistic scenarios, courts …

Brain Scans As Evidence: Truths, Proofs, Lies, And Lessons, Owen D. Jones, Francis X. Shen

Vanderbilt Law School Faculty Publications

This contribution to the Brain Sciences in the Courtroom Symposium identifies and discusses issues important to admissibility determinations when courts confront brain-scan evidence. Through the vehicle of the landmark 2010 federal criminal trial U.S. v. Semrau (which considered, for the first time, the admissibility of brain scans for lie detection purposes) this article highlights critical evidentiary issues involving: 1) experimental design; 2) ecological and external validity; 3) subject compliance with researcher instructions; 4) false positives; and 5) drawing inferences about individuals from group data. The article’s lessons are broadly applicable to the new wave of neurolaw cases now being seen …

Forensic Science: Why No Research?, Paul C. Giannelli

Faculty Publications

The National Academy of Sciences ground-breaking report on forensic science – Strengthening Forensic Science in the United States: A Path Forward – raised numerous issues. One dominant theme that runs throughout the Report is the failure of some forensic science disciplines to comport with fundamental scientific principles – in particular, to support claims with empirical research. The Report observed that “some forensic science disciplines are supported by little rigorous systematic research to validate the discipline’s basic premises and techniques. There is no evident reason why such research cannot be conducted.”

The Report went on to identify fingerprint examinations, firearms (ballistics) …

Repeating, Yet Evading Review: Admitting Reliable Expert Testimony In Criminal Cases Still Depends Upon Who Is Asking, Wes R. Porter

Publications

A trial court must find that the proponent of expert witness testimony has set forth adequate evidence that the testimony is based upon reliable methods and will be helpful to the trier of fact. Much has been written regarding the reliability prong since the Supreme Court’s decision in Daubert v. Merrell Dow Pharm., yet a severe prejudice to the criminally accused persists today in some trial courts’ analyses of the often overlooked helpfulness prong. Despite the straight-forward articulation of helpfulness, described as “fit” or mere relevance, some trial courts apply the helpfulness prong differently depending upon whether the expert testimony …

Independent Judicial Research In The "Daubert" Age, Edward K. Cheng

Vanderbilt Law School Faculty Publications

The Supreme Court's Daubert trilogy places judges in the unenviable position of assessing the reliability of often unfamiliar and complex scientific expert testimony. Over the past decade, scholars have therefore explored various ways of helping judges with their new gatekeeping responsibilities. Unfortunately, the two dominant approaches, which focus on doctrinal tests and external assistance mechanisms, have been largely ineffective. This Article advocates for a neglected but important method for improving scientific decision making-independent judicial research. It argues that judges facing unfamiliar and complex scientific admissibility decisions can and should engage in independent library research to better educate themselves about the …

Does Frye Or Daubert Matter? A Study Of Scientific Admissibility Standards, Edward K. Cheng, Albert Yoon

Vanderbilt Law School Faculty Publications

Nearly every treatment of scientific evidence begins with a faithful comparison between the Frye and Daubert standards. Since 1993, jurists and legal scholars have spiritedly debated which standard is preferable and whether particular states should adopt one standard or the other. These efforts beg the question: Does a state's choice of scientific admissibility standard matter? A growing number of scholars suspect that the answer is no. Under this theory, the import of the Supreme Court's Daubert decision was not in its doctrinal standard, but rather in the general consciousness it raised about the problems of unreliable scientific evidence. This Article …

Can Fingerprints Lie?: Re-Weighing Fingerprint Evidence In Criminal Jury Trials, Tamara F. Lawson

Articles

This article discusses fingerprint evidence and its use in criminal jury trials. It is commonly thought that fingerprints "never lie"; however, this article reveals the little known fact that the "science" of fingerprint identification has never been empirically tested or proven to be reliable. It further exposes the seldom-discussed issue of fingerprint misidentification and latent print examiner error. The article explains the importance of fingerprint evidence and its extensive use in all phases of the criminal justice system. Specifically, the article plays out the dramatic courtroom scenario of incriminating fingerprints being found at a crime scene and matching the accused …

Reliability And The Admissibility Of Experts, Dale A. Nance

Faculty Publications

Modern law on expert testimony insists, as a condition of admissibility, that the asserted expertise be determined by the trial judge to be reliable. Reliability is usually characterized as a dichotomous attribute of evidence, as if expertise were either reliable or unreliable. This article argues that making progress in the development of meaningful and appropriate restrictions on the admissibility of expert testimony requires that we abandon this conceptualization and understand the implications of endorsing a gradational notion of reliability in which evidence can be more or less reliable and in which a comparative assessment of reliability is prominent. Consistent with …

Choice And Boundary Problems In Logerquist, Hummert, And Kumho Tire, David H. Kaye

Journal Articles

This article, part of a symposium on the opinion of the Arizona Supreme Court in Logerquist v. McVey, questions that court’s rationales for refusing to apply heightened scrutiny to psychiatric testimony about the retrieval of repressed memories. It also challenges the court’s use of a “personal observations” exception to the heightened scrutiny standard of Frye v. United States. It proposes that a better solution to problems of scientific and expert evidence would be to adopt a sliding scale that attends to the use to which the evidence is put and the degree to which it has been shown to be …
