Science In The Jury Box: Jurors' Views And Understanding Of Mitochondrial Dna Evidence, Valerie P. Hans, David H. Kaye, 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 …

Credibility: A Fair Subject For Expert Testimony?, Anne Poulin

Working Paper Series

This article explores the ways in which experts can assist the jury to assess the credibility of other witnesses and suggests analytical approaches to such expert testimony. The article argues that the courts should be more receptive to expert testimony bearing on witness credibility and engage in a more nuanced consideration of the role played by proffered expert testimony and how the role of the evidence affects its admissibility. Doing so should lead the courts to embrace the promise of the modern rules of evidence and permit experts to assist juries as they assess credibility.

The (Futile) Search For A Common Law Right Of Confrontation: Beyond Brasier's Irrelevance To (Perhaps) Relevant American Cases, Randolph N. Jonakait

Articles & Chapters

After Crawford v. Washington asserted that the Confrontation Clause constitutionalized the common law right of confrontation, cases have been suggested that illustrate that right. This short essay considers whether the 1779 English case Rex v. Brasier is such a decision, as some contend. The essay concludes that Brasier says nothing about the right of confrontation and points to a comparable framing-era, American case that indicates that general rules about hearsay and confrontation were not at issue. The essay maintains that if the historical understandings of the right of confrontation and hearsay are to control the Confrontation Clause, then framing-era, American …

Out To Lunch: Saks & Koehler Reply To Rudin & Imman's Commentary, Jonathan Koehler

Faculty Working Papers

At several points in their comment on our article in Science (1), Rudin & Inman (2, 3) asserted or clearly implied that we had been dishonest in our presentation. In each of those instances Rudin & Inman's charges are groundless, as we demonstrate below.

Had Rudin & Inman examined the actual source [see Fig. 1, right], they would have discovered that the words were indeed those of Moenssens, that they were consistent with the context in which they appeared, that Moenssens was not quoting Zain or anyone else, and that Saks & Koehler had accurately attributed the statement to its …

Probability, Policy And The Problem Of Reference Class, Robert J. Rhee

Faculty Scholarship

This short paper focuses on the problem of reference class in evidentiary assessment as it relates to probability and weight of evidence. The reluctance to inject mathematical formalism into the factfinding function is justified. Objective probability requires a reference class from which a proportion is derived. Probability assessments change with the reference class. If a proposition is subject to proportional comparison against two or more different references, their selection is often an inductive process. The advantage of objectivity and methodological rigor is illusory. A legal dispute is the search for a plausible understanding of the truth, and an overtly mathematized …

The Science Of Dna Identification: From The Laboratory To The Courtroom (And Beyond), David H. Kaye

Journal Articles

This article focuses on sequences of DNA base-pairs, which are becoming increasingly important in the field of law. These DNA sequences are used by forensic scientists to discover evidence such as blood stains, semen, saliva, and hair, and has become highly useful in the courtroom with regard to exonerating the innocent and convicting the guilty. Part I of the article examines how courts may (or may not) admit DNA evidence in court through four phases: uncritical acceptance; serious challenges to analytical methods and statistical interpretation of the results; renewed acceptance of DNA evidence; and acceptance of advance systems of DNA …

The Perils Of Evidentiary Manipulation, Edward K. Cheng

Vanderbilt Law School Faculty Publications

The use of evidentiary rules to achieve substantive goals strikes me as a Faustian bargain, and, given Bierschbach and Stein's acknowledgedly tentative position, I hope to dissuade them of the virtues of the practice. My goal therefore is to explore briefly the potential dark side of specialized evidentiary rules. The concerns of injecting substantive goals into evidence law extend far beyond the narrow legitimacy concerns Bierschbach and Stein raise. It is not simply the question of whether we aspire to a pluralistic or majority-take-all democratic society. Rather, evidentiary manipulation threatens the legitimacy of criminal and evidence law... Bierschbach and Stein's …

Poetic (In)Justice? Rap Music Lyrics As Art, Life, And Criminal Evidence, Andrea L. Dennis

Scholarly Works

Courts routinely admit defendant-authored rap music lyrics as substantive evidence in the adjudication of criminal cases. In doing so, courts fail to recognize that rap music lyrics are art. Rather, judges view the interpretation of rap music lyrics as a subject of common knowledge, interpret the defendant's lyrics literally, and characterize lyrics as autobiographical depictions of actual events. In making admissibility decisions, courts must give consideration to the social constraints and artistic conventions impacting the composition and interpretation of rap music lyrics. More particularly, they must understand the commercialized nature of the rap music industry, artist claims of authenticity, and …

Who Knew? Admissibility Of Subsequent Remedial Measures When Defendants Are Without Knowledge Of The Injuries, Mark G. Boyko, Ryan G. Vacca

Law Faculty Scholarship

Federal Rule of Evidence 407 prohibits the introduction of subsequent remedial measures for the purposes of demonstrating negligence, culpable conduct, or product defect. But the rule breaks down, in application and purpose, when a defendant undertakes the new safety measure after the plaintiff's injury, but before the defendant had knowledge of the loss. Such a situation is not uncommon. Would-be defendants frequently improve their products and product safety for a variety of reasons. Toxic exposure cases, where exposure often predates diagnosis of the injury by a decade or more, represent a prime example of cases where defendants are likely to …

Everything New Is Old Again: Brain Fingerprinting And Evidentiary Analogy, Alexandra J. Roberts

Law Faculty Scholarship

Brain Fingerprinting uses electroencephalography to ascertain the presence or absence of information in a subject's brain based on his reaction to particular stimuli. As a new forensic tool, Brain Fingerprinting technology stands poised to exert a tremendous impact on the presentation and outcome of selected legal cases in the near future. It also provides a fertile case study to examine the role of analogical reasoning in the process by which lawyers, experts, judges, and the media influence how factjinders perceive and evaluate unfamiliar types of proof When juridical metaphor disguises, distorts, or destroys ideas, it ceases to serve as an …

A History Of Representations Of Justice: Coincident Preoccupations Of Law And Film, Jessica Silbey

Faculty Scholarship

The American trial and the art of cinema share certain epistemological tendencies. Both stake claims to an authoritative form of knowledge based on the indubitable quality of observable phenomena. Both are preoccupied (sometimes to the point of self-defeat) with sustaining the authority that underlies the knowledge produced by visual perception. The American trial and art of cinema also increasingly share cultural space. Although the trial film (otherwise known as the courtroom drama) is as old as the medium of film the recent spate of popular trial films, be they fictional such as Runaway Jury or documentary such as Capturing the …

"Remarkable Stratagems And Conspiracies": How Unscrupulous Lawyers And Credulous Judges Created An Exception To The Hearsay Rule, Marianne Wesson

Publications

This paper, a companion piece to the author's earlier exploration of the case of Mutual Life Insurance Company v. Hillmon, describes the remarkable record of unethical conduct compiled by the eminent and respectable attorneys for the insurance companies in the course of that litigation. When married with the Supreme Court Justices' uncritical willingness to accept the false narrative thus contrived, these attorneys' misconduct led to the creation of an important rule of evidence - a rule of questionable merit. This article aims to remind us that lawyers who are willing to distort the process of litigation have the power …

Evidentiary Wisdom And Blinders In Perspective: Thoughts On Misjudging, Elaine W. Shoben

Scholarly Works

Empirical studies serve to enlighten the law, even when they simply confirm the wisdom of existing rules. Chris Guthrie's article, Misjudging, primarily serves that useful function—confirming the wisdom of existing rules—even though the author sought to establish something different. Guthrie's article applies insights from cognitive psychology to the resolution of legal disputes and presents some empirical proof of the effect of the application. He concludes that three sets of “blinders”—informational, cognitive, and attitudinal—affect the ability of judges to reach correct resolutions of disputes. He therefore recommends further appreciation of the ability of arbitration and mediation to avoid some of the …

Doctrinal Issues In Evidence And Proof, Paul F. Rothstein

Georgetown Law Faculty Publications and Other Works

The word evidence ordinarily means the statements, events, items, or sensory perceptions that suggest the existence or nonexistence of, or truth or falsity of, another fact. Thus, one may say, “hoofbeats are evidence a horse may be passing.” Proof is similar in meaning but may connote more certainty.

Evidence can also mean the study of either (1) how people make such inferences (especially when conjoined with the word proof) or (2) how law regulates information admissibility in the judicial context. Evidence in the latter sense is the name of a standard law school course in common law countries and a …
