Testing Jury Reforms, Valerie P. Hans, B. Michael Dann, David H. Kaye, Erin J. Farley, Stephanie Albertson

Valerie P. Hans

DNA evidence has become a key law enforcement tool and is increasingly presented in criminal trials in Delaware and elsewhere. The integrity of the criminal trial process turns upon the jury's ability to understand DNA evidence and to evaluate properly the testimony of experts. How well do they do? Can we assist them in the process?

Statistics In The Jury Box: How Jurors Respond To Mitochondrial Dna Match Probabilities, David H. Kaye, Valerie P. Hans, B. Michael Dann, Erin J. Farley, Stephanie Albertson

Valerie P. Hans

This article describes parts of an unusually realistic experiment on the comprehension of expert testimony on mitochondrial DNA (mtDNA) sequencing in a criminal trial for robbery. Specifically, we examine how jurors who responded to summonses for jury duty evaluated portions of videotaped testimony involving probabilities and statistics. Although some jurors showed susceptibility to classic fallacies in interpreting conditional probabilities, the jurors as a whole were not overwhelmed by a 99.98% exclusion probability that the prosecution presented. Cognitive errors favoring the defense were more prevalent than ones favoring the prosecution. These findings lend scant support to the legal argument that mtDNA …

Judges, Juries, And Scientific Evidence, Valerie P. Hans

Valerie P. Hans

The rise in scientific evidence offered in American jury trials, along with court rulings thrusting judges into the business of assessing the soundness of scientific evidence, have produced challenges for judge and jury alike. Many judges have taken up the duty of becoming “amateur scientists.” But what about juries? Surely they too could benefit from assistance as they attempt to master and apply complex testimony about scientific matters during the course of a trial. Concerns about the jury’s ability to understand, critically evaluate, and employ scientific evidence in deciding complex trials have led to many suggestions for reform. This article …

Science Is Not Waiting For The Courts, Robert Sanger

Robert M. Sanger

The Forensic Science Community and the federal government are moving far beyond the courts in an effort to improve the quality of scientific evidence and expert testimony in the courts. Major events in forensics have caused a top to bottom reconsideration of what should count as expert testimony. Last month, the National Institute of Standards and Technology (NIST) and the federal Department of Justice (DOJ) convened the first set of meetings of the Organization of Scientific Area Committees (OSAC). This is a forward-looking approach to forensic science.

The first OSAC meetings were held on February 16 and 17, 2015, at …

Dumping Daubert, Popping Popper And Falsifying Falsifiability: A Re-Assessment Of First Principles, Barbara P. Billauer Esq

barbara p billauer esq

Abstract: The Daubert mantra demands that judges, acting as gatekeepers, prevent para, pseudo or bad science from infiltrating the courtroom. To do so, the Judges must first determine what is ‘science’ and what is ‘good science.’ It is submitted that Daubert is deeply polluted with the notions of Karl Popper who sets ‘falsifiability’ and ‘falsification’ as the demarcation line for that determination. This philosophy has intractably infected case law, leading to bad decisions immortalized as stare decisis, and an unworkable system of decision-making, which negatively impacts litigant expectations. Among other problems is the intolerance of Popper’s system for multiple causation, …

Ultracrepidarianism In Forensic Science: The Hair Evidence Debacle, David H. Kaye

Journal Articles

For over 130 years, scientific sleuths have been inspecting hairs under microscopes. Late in 2012, the FBI, the Innocence Project, and the National Association of Criminal Defense Lawyers joined forces to review thousands of microscopic hair comparisons performed by FBI examiners over several of those decades. The results have been astounding. Based on the first few hundred cases in which hairs were said to match, it appears that examiners “exceeded the limits of science” in over 90% of their reports or testimony. The disclosure of this statistic has led to charges that the FBI “faked an entire field of forensic …

Schultz V. Akzo Nobel Paints: “The Rest Of The Story” Reveals Limited Impact Of Expert Testimony Decision, Richard O. Faulk

Richard Faulk

Certainly, a number of lawyers from both sides of the bar believe that the Schultz decision is important. A review of the record in Schultz, however, reveals a relatively easy explanation for the decision—one that undermines its value as precedent. To understand why this is so, we must go back to the district court’s decision to grant Akzo Nobel’s motion for summary judgment and, with apologies to Paul Harvey, appreciate the “rest of the story.”

Adaptation And The Courtroom: Judging Climate Science, Kirsten Engel, Jonathan Overpeck

Michigan Journal of Environmental & Administrative Law

Climate science is increasingly showing up in courtroom disputes over the duty to adapt to climate change. While judges play a critical role in evaluating scientific evidence, they are not apt to be familiar with the basic methods of climate science nor with the role played by peer review, publication, and training of climate scientists. This Article is an attempt to educate the bench and the bar on the basics of the discipline of climate science, which we contend is a distinct scientific discipline. We propose a series of principles to guide a judge’s evaluation of the reliability and weight …

Law's Treatment Of Science: From Idealization To Understanding, Nayha Acharya

Dalhousie Law Journal

Increasing reliance on scientific evidence in litigation has created a demand for discussions directed at enabling a legitimate interaction between science and law The article develops the notion ofprocedural legitimacy-that adherence to legal procedure maintains the legitimacy of the adjudicative system and its outcomes -and applies it to determining how best to admit and use scientific evidence. The problem of undervaluing procedural legitimacy is illustrated through a commentary on contributions to the science and law discussion of Edmond and Roach, and Haack. The author's thesis is that maintaining adjudicative legitimacy depends on procedural rules being applied as vigilantly to science …

Response To Haack And Edmond/Roach Articles, Nayha Acharya

Dalhousie Law Journal

I am grateful to Professors Edmond and Roach' and Professor Haack2 for their thoughtful replies to my paper, Law 's Treatment of Science: From Idealizationto Understanding.Much like my experience after reading "A Contextual Approach to the Admissibility of the State's Forensic Science and Medical Evidence,"' and Haack's contributions, 4 I have come away from reviewing Edmond and Roach and Haack's replies with a heightened awareness that the admissibility of scientific evidence is significant and complicated. Both replies have raised important concerns that have demanded further attention from me, which I turn to here. My response to Edmond and Roach's Reply …

Making Method Visible: Improving The Quality Of Science-Based Regulation, Pasky Pascual, Wendy Wagner, Elizabeth Fisher

Michigan Journal of Environmental & Administrative Law

Scientific inferences are theories about how the world works that scientists formulate based on their observations. One of the most difficult issues at the intersection of law and science is to determine whether the weight of evidence supports one scientific inference versus other competing interpretations of the observations. In administrative law, this difficulty is exacerbated by the behavior of both the courts and regulatory agencies. Agencies seldom achieve the requisite visibility that explains the analytical methods they use to reach their scientific inferences. Courts—because they appreciate neither the variety of inferential methods nor their epistemic foundations—do not demand this level …

Confronting Science: Expert Evidence And The Confrontation Clause, David H. Kaye, Jennifer L. Mnookin

Journal Articles

In Crawford v Washington, the Supreme Court substantially changed its understanding of how the Confrontation Clause applies to hearsay evidence. Since then, the Court has issued three bitterly contested expert-evidence-related Confrontation Clause decisions, and each one has generated at least as many questions as answers. This article analyzes this trilogy of cases, especially the most recent, Williams v Illinois.

In Williams, the Court issued a bewildering array of opinions in which majority support for admitting the opinion of a DNA analyst about tests that she did not perform was awkwardly knitted together out of several incompatible doctrinal …

Being Pragmatic About Forensic Linguistics, Edward K. Cheng

Vanderbilt Law School Faculty Publications

This article aims to provide some legal context to the Authorship Attribution Workshop (“conference”). In particular, I want to offer some pragmatic observations on what courts will likely demand of forensic linguistics experts and tentatively suggest what the field should aspire to in both the short and long run.

Speaking Science To Law, Deborah Hussey Freeland

Deborah M. Hussey Freeland

involving a strong scientific consensus, the powerful qualities of scientific knowledge are easily lost in translation. Moreover, even prominent scientists who are committed to providing accurate information to legal fact-finders may suffer reputational harm simply for participating in an adversarial process.

This article analyzes the connection between law and science through the expert witness from the perspectives of epistemology and cross-cultural communication, focusing on the distinct ways in which scientists and lawyers know, value and express their knowledge. When a lawyer meets with a scientific expert witness, more confusion attends their interaction than either likely realizes. Linguistic translation is necessary--but …

Using Brain Imaging For Lie Detection: Where Science, Law, And Policy Collide, Daniel D. Langleben, Jane Campbell Moriarty

Jane Campbell Moriarty

Progress in the use of functional magnetic resonance imaging (fMRI) of the brain to differentiate lying from truth-telling has created an expectation of a breakthrough in the search for objective methods of lie detection. In the last few years, litigants have attempted to introduce fMRI-based lie detection evidence in courts. Both the science and its possible use as courtroom evidence have spawned much scholarly discussion. This article contributes to the interdisciplinary debate by identifying the missing pieces of the scientific puzzle that need to be completed if fMRI-based lie detection is to meet the standards of either legal reliability or …

The 2009 Nas Forensic Science Report: A Literature Review, Paul C. Giannelli

Faculty Publications

In February 29, the National Academy of Sciences (NAS) released its report on forensic science: Strengthening Forensic Science in the United States: A Path Forward (29). The popular press immediately trumpeted the report’s release, with headlines such as (1) “Report Urges Overhaul of Crime Lab System,” (2) “Real-life Police Forensics Don’t Resemble ‘CSI’: Reliability is ‘Low or Non-existent,’ Report Finds” and (3) “Science Found Wanting in Nation’s Crime Labs.”

Within three months of its publication, Justice Scalia cited the report in a Supreme Court decision, writing: “Forensic evidence is not uniquely immune from the risk of manipulation. . . Serious …

Can You Provide Evidence Of Insufficient Evidence? The Precautionary Principle At The Wto, Elisa Vecchione

Elisa Vecchione

This paper aims to demonstrate that the WTO jurisprudence on science-related trade disputes has become entangled with a specific vision of science that has prevented any possible application of the precautionary principle. This situation is due to reasons of both legal procedures specific to the WTO dispute settlement system and the substantive nature of precautionary measures. Indeed, their foundation on “insufficient scientific evidence” dramatically complicates the question of the probative value of science for the purpose of legal adjudication and creates a seemingly contradictory situation, of which the Panel on the EC-Biotech case confirmed to be a victim: that of …

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 …

Who Must Testify To The Results Of A Forensic Laboratory Test? Bullcoming V. New Mexico, Richard D. Friedman

Does the Confrontation Clause permit the prosecution to introduce a forensic laboratory report through the in-court testimony of a supervisor or other person who did not perform or observe the reported test?

Residential Protectionism And The Legal Mythology Of Home, Stephanie M. Stern

Michigan Law Review

The theory that one's home is a psychologically special form of property has become a cherished principle of property law, cited by legislators and touted extensively in the legal scholarship. Influential scholars, most notably Margaret Radin, have asserted that ongoing control over one's home is necessary for an individual's very personhood and ability to flourish in society. Other commentators have expounded a communitarian vision of the home as rooting individuals in communities of close-knit social ties. Remarkably, the legal academy has accepted these theoretical accounts of the home without demanding a shred of empirical evidence. The misplaced belief in the …

Hon. Donald E. Shelton

This artice discusses the challenges faced by trial judges in crimnal cases in fulfilling their Daubert "gatekeeping" role in the face of rapid advancements in forensic science. Admissibility questions for various forms of scientific evidence are reviewed, from DNA to fingerprints to social science "syndrome" evidence. The article discusses the pretrial issues presented by DNA databases, search issues and limitations problems as well as the impact of forensic science developments on juror expectations. Finally, forensic science issues regarding trial conduct are discussed, including voir dire, arguments and jury instructions,

The Death Penalty In Florida, Christopher Slobogin

Vanderbilt Law School Faculty Publications

This article summarizes the findings and recommendations of the ABA Death Penalty Moratorium Implementation Project's Florida Assessment Team, which I chaired. Relying on an analysis of caselaw, studies, news reports, and interviews, the article describes significant flaws in Florida's death penalty law and practice in nine areas: the police investigative process; the analysis of scientific evidence; the conduct of prosecutors; the qualifications, reimbursement and competence of defense attorneys; the decision-making process of judges; the structure and decision-making process of capital sentencing juries; clemency; the system's reaction to the race of the victim; and the treatment of people with mental disability. …

An Indirect-Effects Model Of Mediated Adjudication: The Csi Myth, The Tech Effect, And Metropolitan Jurors' Expectations For Scientific Evidence, Hon. Donald E. Shelton, Young S. Kim, Gregg Barak

Vanderbilt Journal of Entertainment & Technology Law

Part I of this article defines the "CSI effect," a phrase has come to have many different meanings ascribed to it. It emphasizes the epistemological importance of first describing the effect of the "CSI effect" as observed in juror behavior documented in a new study conducted in Wayne County (Detroit), Michigan, and then looking at causative factors that may be related to an explanation of those observed effects. Part II describes the methodology of the Wayne County study, provides a descriptive analysis of Wayne County jurors, and compares the jurors demographically to the Washtenaw County jurors who were surveyed in …

Crawford Confusion Marches On: The Confrontation Clause And Hearsay Laboratory Drug Reports, David A. Doellman

Missouri Law Review

Rapid advances in science and technology have influenced criminal prosecutions as police often utilize advanced technology to obtain evidence that is integral to the prosecution's case against a criminal defendant. Such practices are especially common in cases involving illegal drugs, in which slight variations in the precise measurements of such substances could add or subtract from the lengths of sentences. Often, prosecutors offer this crucial evidence in court through a laboratory report documenting the exact results of the tests performed on the alleged illegal substances. The admission of these lab reports seemingly complies with the rules of evidence of most …

Science On Trial, Valerie P. Hans

Cornell Law Faculty Publications

The increasing complexity of both criminal and civil jury trials raises a host of issues for lawyers and judges. For the litigator, the first question is whether a jury can be trusted with a case that turns on highly technical evidence. For the trial judge, there are decisions about the admissibility of expert testimony, whether it is based on sound science, and whether a jury is likely to be misled by scientific claims. Should the judge permit jury innovations such as note taking, question asking, and juror discussions of evidence during the trial, hoping to increase jury comprehension of the …
