The Consensus Rule: A New Approach To Scientific Evidence, Edward K. Cheng Jan 2022

The Consensus Rule: A New Approach To Scientific Evidence, Edward K. Cheng

Vanderbilt Law School Faculty Publications

Founded on good intentions but unrealistic expectations, the dominant Daubert framework for handling expert and scientific evidence should be scrapped. Daubert asks judges and jurors to make substantively expert determinations, a task they are epistemically incompetent to perform as laypersons. As an alternative, this Article proposes a new framework for handling expert evidence. It draws from the social and philosophical literature on expertise and begins with a basic question: How can laypersons make intelligent decisions about expert topics? From there, it builds its evidentiary approach, which ultimately results in an inference rule focused on expert communities. Specifically, when dealing with …


Proving Copying, Shyamkrishna Balganesh, Peter S. Menell Jan 2022

Proving Copying, Shyamkrishna Balganesh, Peter S. Menell

Faculty Scholarship

Proof that a defendant actually copied from a copyrighted work is a critical part of a claim for copyright infringement. Indeed, absent such copying, there is no infringement. The most common method of proving copying involves the use of circumstantial evidence, consisting of proof that a defendant had “access” to the protected work, and a showing of “similarities” between the copy and the protected work. In inferring copying from the combination of such evidence, courts have for many decades developed a framework known as the “inverse ratio rule,” which allows them to modulate the level of proof needed on access …

Introduction, Shari S. Diamond, Richard O. Lempert

Articles

Experts bedeviled the legal system long before seventeenth-century Salem, when the town's good citizens relied on youthful accusers and witchcraft experts to identify the devil's servants in their midst. As in Salem, claims of expertise have often been questioned and objections raised about the bases of expert knowledge. Expertise, then and now, did not have to be based on science; but the importance of science and the testimony of scientific experts has since medieval times been woven into the fabric of the English jurisprudence that Americans inherited. In cases as long ago as 1299 we find examples of courts seeking …


Debunked, Discredited, But Still Defended: Why Prosecutors Resist Challenges To Bad Science And Some Suggestions For Crafting Remedies For Wrongful Conviction Based On Changed Science, Aviva A. Orenstein Jan 2018

Debunked, Discredited, But Still Defended: Why Prosecutors Resist Challenges To Bad Science And Some Suggestions For Crafting Remedies For Wrongful Conviction Based On Changed Science, Aviva A. Orenstein

Articles by Maurer Faculty

Flawed science has significantly contributed to wrongful convictions. Courts struggle with how to address such convictions when the mistaken science (such as bogus expert claims about the differences between accidental fires and intentionally set ones) significantly affected the guilty verdict but there is no DNA evidence to directly exonerate the accused. My short piece explores why prosecutors often defend bad science. Mistakes in science tend to serve the prosecution, but there are other more subtle factors that explain prosecutors’ reluctance to address flawed forensic testimony. Such reluctance may arise from fondness for the status quo and a resistance to subverting …

Tender Is The Night: Should Your Expert Be?, Cynthia Ford Jan 2013

Tender Is The Night: Should Your Expert Be?, Cynthia Ford

Faculty Journal Articles & Other Writings

This article discusses the practice of tendering an expert for acceptance or certification by the court at trial in the presence of the jury. The article considers Tennessee and Montana state and federal evidence law. The author suggests that Montana courts and lawyers should comply with the A.B.A. Updated Civil Trial Standard 14 and let juries assess the testimony of a Rule 702 witness without a special designation accorded by the judge certifying a witness as an "expert" in his or her field.


Williams V. Illinois And The Confrontation Clause: Does Testimony By A Surrogate Witness Violate The Confrontation Clause?, Paul F. Rothstein, Ronald J. Coleman Jan 2011

Williams V. Illinois And The Confrontation Clause: Does Testimony By A Surrogate Witness Violate The Confrontation Clause?, Paul F. Rothstein, Ronald J. Coleman

Georgetown Law Faculty Publications and Other Works

This article comprises a four-part debate between Paul Rothstein, Professor of Law at Georgetown Law Center, and Ronald J. Coleman, who works in the litigation practice group at Cleary Gottlieb Steen & Hamilton LLP, on Williams v. Illinois, a Supreme Court case that involves the Confrontation Clause, which entitles a criminal defendant to confront an accusing witness in court. The issue at hand is whether said clause is infringed when a report not introduced into evidence at trial is used by an expert to testify about the results of testing that has been conducted by a non-testifying third party. …

A Matter Of Context: Social Framework Evidence In Employment Discrimination Class Actions, Melissa Hart, Paul M. Secunda Jan 2009

A Matter Of Context: Social Framework Evidence In Employment Discrimination Class Actions, Melissa Hart, Paul M. Secunda

Publications

In litigation disputes over the certification of employment discrimination class actions, social scientists have come to play a central, yet controversial, role. Organizational behavioralists and social psychologists regularly testify for the plaintiffs, offering what is commonly referred to as social framework testimony. These experts explain the general social science research on the operation of stereotyping and bias in decision making and examine the challenged workplace to identify those policies and practices that research has shown will tend to increase and those that will tend to limit the likely impact of these factors. Defendants fight hard against the admission of social …


Science On Trial, Valerie P. Hans Apr 2008

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 …


Experts, Mental States, And Acts, Christopher Slobogin Jan 2008

Experts, Mental States, And Acts, Christopher Slobogin

Vanderbilt Law School Faculty Publications

This article, written for a symposium on "Guilt v. Guiltiness: Are the Right Rules for Trying Factual Innocence Inevitably the Wrong Rules for Trying Culpability?," argues that the definition of expertise in the criminal justice system, derived in the federal courts and in most states from Daubert v. Merrell Dow Pharmaceuticals Co., should vary depending on whether the issue involved is past mental state or past conduct. While expert psychological testimony about past acts ought to be based on scientifically verifiable assertions, expert psychological testimony about subjective mental states relevant to criminal responsibility need not meet the same threshold. This …


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 Dec 2007

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

Cornell Law Faculty Publications

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 Jan 2007

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

Cornell Law Faculty Publications

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.

Can Jury Trial Innovations Improve Juror Understanding Of Dna Evidence?, B. Michael Dann, Valerie P. Hans, David H. Kaye Nov 2006

Can Jury Trial Innovations Improve Juror Understanding Of Dna Evidence?, B. Michael Dann, Valerie P. Hans, David H. Kaye

Cornell Law Faculty Publications

A single spot of blood on a pink windowsill will tell investigators who broke a windowpane, turned a lock, and kidnapped 2-year-old Molly Evans from her bedroom in the middle of the night. An expert witness will testify that the DNA profile of the blood evidence recovered from the windowsill was entered into CODIS, an electronic database of DNA profiles. That process yielded a “hit,” identifying the defendant as the most likely source of the blood inside Molly’s room.

But will jurors be able to understand the expert’s intricate analysis and use it to reach a verdict? And what—if any—steps …

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

Cornell Law Faculty Publications

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?


Economic Authority And The Limits Of Expertise In Antitrust Cases, John E. Lopatka, William H. Page Mar 2005

Economic Authority And The Limits Of Expertise In Antitrust Cases, John E. Lopatka, William H. Page

UF Law Faculty Publications

In antitrust litigation, the factual complexity and economic nature of the issues involved require the presentation of economic expert testimony in all but a few cases. This dependence on economics has increased in recent years because of the courts' narrowing of per se rules of illegality and the courts' expansion of certain areas of factual inquiry. At the same time, however, courts have limited the scope of allowable expert testimony through the methodological strictures of Daubert and its progeny and through heightened sufficiency requirements. In this Article, Professors Page and Lopatka make four important points about these judicially imposed constraints …


A Non-Romantic View Of Expert Testimony, Lewis H. Larue, David S. Caudill Jan 2004

A Non-Romantic View Of Expert Testimony, Lewis H. Larue, David S. Caudill

Scholarly Articles

The Daubert trilogy as a whole deflects attention away from abstract identifications of scientific validity (including the demarcation controversy aimed at rooting out allegedly junk science from the courtroom), and toward the application of expertise to the particular case at hand. That emphasis on application is reflected as well in post-trilogy scholarship, wherein we see three patterns or contours that both help quiet the debates and provide useful guidance to judges and lawyers. First, there is a pragmatic recognition, in various forms, that the focus should be on how science is being used rather than on science in the abstract. …

Jurors' Evaluations Of Expert Testimony: Judging The Messenger And The Message, Sanja Kutnjak Ivkovic, Valerie P. Hans Apr 2003

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

Cornell Law Faculty Publications

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 …


Can Fingerprints Lie?: Re-Weighing Fingerprint Evidence In Criminal Jury Trials, Tamara F. Lawson Jan 2003

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 …


The Other Shoe Drops: Minnesota Rejects Daubert, Peter B. Knapp Jan 2002

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 …
