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 …

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.

Every Juror Wants A Story: Narrative Relevance, Third Party Guilt And The Right To Present A Defense, John H. Blume, Sheri L. Johnson, Emily C. Paavola

Cornell Law Faculty Publications

On occasion, criminal defendants hope to convince a jury that the state has not met its burden of proving them guilty beyond a reasonable doubt by offering evidence that someone else (a third party) committed the crime. Currently, state and federal courts assess the admissibility of evidence of third-party guilt using a variety of standards. In general, however, there are two basic approaches. Many state courts require a defendant to proffer evidence of some sort of direct link or connection between a specific third-party and the crime. A second group of state courts, as well as federal courts, admit evidence …

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 …

On The Legal Consequences Of Sauces: Should Thomas Keller's Recipes Be Per Se Copyrightable?, Christopher J. Buccafusco

All Faculty Scholarship

The restaurant industry now takes in over $500 billion a year, but recent courts have been skeptical of the notion that one of its most valuable assets, original recipes, are subject to copyright protection. With more litigation looming and the contours of the debate insufficiently mapped out, this article establishes the appropriate groundwork for analyzing the copyrightability of recipes. I show that, contrary to recent appellate court opinions, recipes meet the statutory requirements for copyrightability. I argue, by analogizing to musical compositions, that written recipes work to satisfy the fixation requirement of copyright law just as musical notation does for …

Chimeras: Double The Dna - Double The Fun For Crime Scene Investigators, Prosecutors, And Defense Attorneys?, Catherine Arcabascio

Faculty Scholarship

This article first explores the mythological origins of the term "chimera." It then explores the causes and scientific explanations of chimerism and the various conditions covered by the term chimera in the area of genetics. Although this article will discuss the various chimeric conditions that are thought to exist, its primary focus is on chimerism that is the result of the fusing of embryos in utero. Next, the article will discuss recent cases of chimerism - and of alleged chimerism - and how the genetic differences between chimeras and the general population came to light. It also will discuss …

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 …

A Suspicionless Search And Seizure Quagmire: The Supreme Court Revives The Pretext Doctrine And Creates Another Fine Fourth Amendment Mess, Edwin J. Butterfoss

Faculty Scholarship

This Article contends the Supreme Court's use of a primary purpose test to regulate suspicionless searches and seizures by the government is misguided and will provide little or no protection against the evils that apparently led the Court to strike down recent schemes by government officials. The evil of the government schemes is less the purpose of the schemes than their expansion into areas and activities in which citizens should be protected from government intrusion in the absence of any suspicion of wrongdoing. Rather than facing this head on and carefully assessing whether the government schemes infringe on such areas …

Revisiting 'Dreyfus': A More Complete Account Of A Trial By Mathematics, David H. Kaye

Journal Articles

Legal literature and case law depicts the infamous conviction of Alfred Dreyfus for treason and espionage in 1899 as a prime example of the irresistible power of even grossly fallacious mathematical demonstrations to overwhelm a legal tribunal. This essay shows that Dreyfus is not a case of mathematics run amok, unchecked and uncomprehended. To the contrary, the defects in the mathematical proof were dramatically exposed, and this evidence did not lead Dreyfus's judges to condemn him. This history undercuts the reliance of modern courts and commentators on Dreyfus as an indication or illustration of the alleged dangers of probability evidence …

Please, Let's Bury The Junk: The Codis Loci And The Revelation Of Private Information, David H. Kaye

Journal Articles

This Northwestern University Law Review Colloquy paper describes the four possible ways in which genetic loci could possess predictive or diagnostic value with regard to diseases and explains why these mechanisms have not led, and probably cannot lead, to useful screening tests with the Convicted Offender DNA Index System (CODIS) profiles in national, state, and local databases. It then considers the phenotypes and familial relationships that the CODIS STRs can be used to identify. The profiles carry limited information about an individual's race and familial relationships, and the article places the resulting privacy issues in perspective. Finally, the paper comments …

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 …

Parol Evidence Under The Cisg: The "Homeward Trend" Reconsidered, 68 Ohio St. L.J. 133 (2007), Karen H. Cross

UIC Law Open Access Faculty Scholarship

The CISG has been described as one of history 's most successful attempts to harmonize international commercial law. Consistent with its goal of harmonizing the law of international sales, Article 7(1) of the CISG instructs courts and arbitrators to interpret the Convention in light of "its international character and the need to promote uniformity in its application. " MCC-Marble v. Ceramica Nuova D'Agostina is a U.S. decision that has been praised for its adherence to Article 7(1). In contrast with conventional academic commentary, which praises MCC-Marble and criticizes the tendency of courts to interpret the CISG in light of their …

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.

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 …

Bite Mark Analysis, Paul C. Giannelli

Faculty Publications

Courts have admitted bite mark comparison evidence in homicide, rape, and child abuse cases. By the 1980s, the technique had gained widespread judicial acceptance. Hundreds of cases have admitted this type of evidence, and no reported case has rejected it. Moreover, some courts speak of bite mark comparison as a "science." Indeed, its acceptance is so well-established that several courts have taken judicial notice of its reliability, implying that the validity of the technique is not subject to reasonable dispute.

Yet, the scientific foundations for bite mark comparisons has never been demonstrated. Such basic issues as the uniqueness of the …

Crawford And Davis: A Personal Reflection, Richard D. Friedman

Articles

I have to say that when I stood up to argue Hammon I felt the wind at my back. I was basically a lawyer with an easy case, and there wasn't anything particularly unpredictable at the argument of Hammon. Now it got a little bit interesting, as I will explain later, because to a certain extent I was trying to argue the other case as well. But Hammon itself was sort of ordinary, normal law.
