Bayes' Law, Sequential Uncertainties, And Evidence Of Causation In Toxic Tort Cases, Neal C. Stout, Peter A. Valberg

University of Michigan Journal of Law Reform

Judges are the gatekeepers of evidence. Arguably, the most difficult duty for a judicial gatekeeper is to screen the reliability of expert opinions in scientific fields such as medicine that are beyond the ken of most judges. Yet, judges have a duty to scrutinize such expert opinion evidence to determine its reliability and admissibility. In toxic tort cases, the issue of causation-whether the alleged exposures actually caused the plaintiffs injury-is nearly always the central dispute, and determining admissibility of expert causation opinion is a daunting challenge for most judges. We present a comprehensive review of the courts' struggles with the …

Reenvisioning Law Through The Dna Lens, Edward K. Cheng

Vanderbilt Law School Faculty Publications

In recent times, no development has transformed the practice of criminal justice as much as DNA evidence. In little over fifteen years, DNA profiling has produced nothing short of a paradigm shift.1 For police and prosecutors, DNA has become a potent weapon for identifying and convicting criminals. Trace biological material left at a crime scene now provides critical evidence for generating leads through "cold searches" of DNA databases and for convicting defendants at trial. At the same time, for defense attorneys, DNA has become an invaluable tool for seeking exonerations, because just as DNA can link defendants to crimes, it …

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 …

Cross-Examining The Brain: A Legal Analysis Of Neural Imaging For Credibility Impeachment, Charles N. W. Keckler

ExpressO

The last decade has seen remarkable process in understanding ongoing psychological processes at the neurobiological level, progress that has been driven technologically by the spread of functional neuroimaging devices, especially magnetic resonance imaging, that have become the research tools of a theoretically sophisticated cognitive neuroscience. As this research turns to specification of the mental processes involved in interpersonal deception, the potential evidentiary use of material produced by devices for detecting deception, long stymied by the conceptual and legal limitations of the polygraph, must be re-examined. Although studies in this area are preliminary, and I conclude they have not yet satisfied …

Voice Over Internet Protocol And The Wiretap Act: Is Your Conversation Protected?, Daniel B. Garrie, Matthew J. Armstrong, Donald P. Harris

Seattle University Law Review

10101101: Is this sequence of digits voice or data? To a computer, voice is a sequence of digits and data is a sequence of digits. The law has defined 10101101 to be data, and 10101001 to be voice communications. Courts have constructed a distinction between data, 10101101, and voice, 10101001. However, that distinction is blurred when voice and data are simultaneously transmitted through the same medium. The courts forbid third parties to tap or monitor voice communications, yet permit data packets to be tracked, stored, and sold by third parties with the implied consent of either party engaged in the …

Electronic Discovery Sanctions In The Twenty-First Century, Shira A. Scheindlin, Kachana Wangkeo

Michigan Telecommunications & Technology Law Review

At the federal level, the Civil Rules Advisory Committee has responded to the "unique and necessary feature of computer systems--the automatic recycling, overwriting, and alteration of electronically stored information"--with a proposed amendment to Rule 37. The proposed Rule 37(f) would shield litigants from sanctions for the destruction of electronic data if the party "took reasonable steps to preserve the information after it knew or should have known the information was discoverable in the action" and "the failure resulted from the loss of the information because of the routine operation of the party's electronic information system." The safe harbor provision would …

Ake V. Oklahoma: The Right To Expert Assistance In A Post-Daubert, Post-Dna World, Paul C. Giannelli

Faculty Publications

Although securing the services of defense experts to examine evidence, to advise counsel, and to testify at trial is frequently critical in modern criminal litigation, it was not until 1985 that the United States Supreme Court in Ake v. Oklahoma, 470 U.S. 68 (1985), recognized, for the first time, a constitutional right to expert assistance. In a system in which an overwhelming majority of criminal defendants are indigent, Ake was a landmark case. Nevertheless, the Ake Court could not have anticipated how the advent of DNA evidence would revolutionize forensic science or how the Daubert trilogy would alter the judicial …

Changing Scientific Evidence, Edward K. Cheng

Vanderbilt Law School Faculty Publications

A number of high-profile toxic tort cases, such as silicone breast implants, have followed a familiar and disturbing path: Early studies suggest a link between a suspected substance and a particular illness. Based on these initial studies, lawsuits are brought and juries award large judgments to various plaintiffs. Then later, more comprehensive studies find no evidence of a causal link. How should the legal system cope with this problem in which new scientific evidence calls into question previous findings of liability? These erroneous judgments seriously harm social welfare and legitimacy. Beneficial products are needlessly discontinued or are made more expensive, …

Dna Identification Databases: Legality, Legitimacy, And The Case For Population-Wide Coverage, David H. Kaye, Michael E. Smith

Faculty Scholarship

Over the past decade, law enforcement authorities have amassed huge collections of DNA samples and the identifying profiles derived from them. Large DNA databanks routinely help to identify the guilty and to exonerate the innocent, but as the databanks grow, so do fears about civil liberties. Perhaps the most controversial policy issue in the creation of these databases is the question of coverage: Whose DNA profiles should be stored in them? The possibilities extend from convicted violent sex offenders to all convicted felons, to everyone arrested, to the entire population. This Article questions the rationales for drawing the line at …

Expert Information And Expert Evidence: A Preliminary Taxonomy, Samuel R. Gross, Jennifer L. Mnookin

Articles

Federal Rule of Evidence 702 speaks in very general terms. It governs every situation in which "scientific, technical or other specialized knowledge will assist the trier of fact," and provides that, in that situation, "a witness qualified as an expert by knowledge, skill, experience, or education, may testify thereto in the form of an opinion or otherwise . . . .' In 2000, following a trio of Supreme Court cases interpreting Rule 702, the Rule was amended to include a third requirement, in addition to the helpfulness of the testimony and the qualifications of the witness: reliability. Under Rule 702 …

Expert Testimony On Fingerprints: An Internet Exchange, Richard D. Friedman, David H. Kaye, Jennifer Mnookin, Dale Nance, Michael Saks

Articles

In United States v. Llera Plaza, 188 F. Supp. 2d 549 (E.D. Pa. 2002), a federal district initially limited expert opinion testimony on fingerprint identifications because the government was unable to show that such identifications were sufficiently valid and reliable under Federal Rule of Evidence 702. Then, the court withdrew the opinion. This article reproduces an exchange of notes on the initial opinion submitted by five law professors.

Daubert's Backwash: Litigation-Generated Science, William L. Anderson, Barry M. Parsons, Drummond Rennie

University of Michigan Journal of Law Reform

In the 1993 landmark case Daubert v. Merrell Dow Pharmaceuticals, the United States Supreme Court articulated its position on the admissibility of scientific evidence. The Court reasoned that federal judges should rely on the processes scientists use to identify unreliable research, including the process of peer review, to determine when scientific evidence should be inadmissible. In response, lawyers and their clients, seeking to rely on such evidence, have begun funding and publishing their own research with the primary intention of providing support to cases they are litigating. This Article examines the phenomenon of litigation-generated science, how it potentially undermines …

Two Fallacies About Dna Data Banks For Law Enforcement, David H. Kaye

Faculty Scholarship

This commentary on the article Legal and Policy Issues in Expanding the Scope of Law Enforcement DNA Data Banks, 67 Brook. L. Rev. 127 (2001), by Mark Rothstein and Sandra Carnahan, argues that the case for confining law enforcement DNA databases to noncoding loci and to samples from individuals convicted of violent crimes is quite weak.

It describes alternative approaches, including the possibility of a population-wide database; the privacy implications of the loci now used in forensic identification; the law governing DNA dragnets; and the limits on DNA databases imposed by recent cases on searches and seizures. It notes the …

The Dynamics Of Daubert: Methodology, Conclusions, And Fit In Statistical And Econometric Studies, David H. Kaye

Faculty Scholarship

This paper reviews the development of the law governing the admissibility of statistical studies. It analyzes the leading cases on scientific evidence and suggests that both the "reliability" and the "general acceptance" standards raise two major difficulties - the "boundary problem" of identifying the type of evidence that warrants careful screening and the "usurpation problem" of keeping the trial judge from closing the gate on evidence that should be left for the jury to assess.

The paper proposes partial solutions to these problems, and it applies them to statistical and econometric proof, particularly in the context of a recent antitrust …

The Constitutionality Of Dna Sampling On Arrest, David H. Kaye

Faculty Scholarship

Every state now collects DNA from people convicted of certain offenses. Law enforcement authorities promote offender DNA databanking on the theory that it will identify offenders who commit additional crimes while or probation or parole, or after they have finished serving their sentences. Even relatively small databases have yielded such dividends. As these database searches uncover the perpetrators of rapes, murders, and other offenses, the pressure builds to expand the coverage of the databases.

Recent proposals call for extending not merely the scope of crimes for which DNA databanking would be used, but also the point at which the samples …

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

Faculty Scholarship

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 …

Dna Typing: Emerging Or Neglected Issues, David H. Kaye, Edward J. Imwinkelried

Faculty Scholarship

DNA typing has had a major impact on the criminal justice system. There are hundreds of opinions and thousands of cases dealing with DNA evidence. Yet, at virtually every stage of the process, there are important issues that are just emerging or that have been neglected.

At the investigative stage, courts have barely begun to focus on the legal limitations on the power of the police to obtain samples directly from suspects and to use the data from DNA samples in various ways. Issues such as the propriety of "DNA dragnets" (in which large numbers of individuals in a geographic …

Amicus Brief: Kumho Tire V. Carmichael, Neil Vidmar, Richard O. Lempert, Shari Seidman Diamond, Valerie P. Hans, Stephan Landsman, Robert Maccoun, Joseph Sanders, Harmon M. Hosch, Saul Kassin, Marc Galanter, Theodore Eisenberg, Stephen Daniels, Edith Greene, Joanne Martin, Steven Penrod, James Richardson, Larry Heuer, Irwin Horowitz

Cornell Law Faculty Publications

This brief addresses the issue of jury performance and jury responses to expert testimony. It reviews and summaries a substantial body of research evidence about jury behavior that has been produced over the past quarter century. The great weight of that evidence challenges the view that jurors abdicate their responsibilities as fact finders when faced with expert evidence or that they are pro-plaintiff, anti-defendant, and anti-business.

The Petitioners and amici on behalf of petitioners make a number of overlapping, but empirically unsupported, assertions about jury behavior in response to expert testimony, namely that juries are frequently incapable of critically evaluation …

Doubts About Daubert: Psychiatric Anecdata As A Case Study, Christopher Slobogin

Vanderbilt Law School Faculty Publications

In Daubert v. Merrell Dow Pharmaceuticals Inc., the Supreme Court sensibly held that testimony purporting to be scientific is admissible only if it possesses sufficient indicia of scientific validity. In Kumho Tire Co. v. Carmichael, the Court more questionably held that opinion evidence based on "technical" and "specialized" knowledge must meet the same admissibility threshold as scientific testimony. This Article addresses the implications of these two decisions for opinion evidence presented by mental health professionals in criminal trials.
