Judges Should Be Discerning Consensus, Not Evaluating Scientific Expertise, David S. Caudill, Harry Collins, Robert Evans

University of Cincinnati Law Review

One of the most constructive critiques of the Daubert admissibility regime is Professor Edward Cheng’s recent proposal for a new Consensus Rule in the Federal Rules of Evidence. Rejecting the notion that judges and juries have the capacity to evaluate scientific expertise, Cheng’s proposal would eliminate Daubert hearings—and judicial gatekeeping concerning expert testimony—and require judges and juries, in their verdicts, to follow consensus in the relevant scientific community. Significantly, Cheng argues that judges and juries would have an easier time identifying consensus than they have in deciding between experts who disagree.

We find Cheng’s emphasis on consensus compelling, and …

Embracing Deference, Edward K. Cheng, Elodie O. Currier, Payton B. Hampton

Vanderbilt Law School Faculty Publications

A fundamental conceptual problem has long dogged discussions about scientific and other expert evidence in the courtroom. In American law, the problem was most famously posed by Judge Learned Hand, who asked: "[H]ow can the jury judge between two statements each founded upon an experience confessedly foreign in kind to their own? It is just because they are incompetent for such a task that the expert is necessary at all." This puzzle, sometimes known as the "expert paradox," is quite general. It applies not only to the jury as factfinder, but also to the judge as gate- keeper under the …

Parental Alienation In Family Court: Attacking Expert Testimony, John E.B. Myers, Jean Mercer

Child and Family Law Journal

In child custody litigation, when a parent raises the possibility of child abuse, the accused parent may respond that the parent wo has raised the possibility of abuse is alienating the child in an effort to gain an unfair advantage in court. The parent accused of abuse may offer expert testimony on parental alienation. A voluminous and contentious social science literature exists on parental alienation. Family law attorneys often lack ready access to social science literature. The purpose of this article is to give family law attorneys information from the parental alienation literature that can be used to cross-examine experts …

The Litigation Landscape Of Fraternity And Sorority Hazing: Defenses, Evidence, And Damages, Gregory S. Parks, Elizabeth Grindell

Washington and Lee Law Review

In recent years, increasing public and media attention has focused on hazing, especially in collegiate fraternities and sororities. Whether it is because of the deaths, major injuries, or litigation, both criminal and civil, collegiate fraternities and sororities have received increased scrutiny. In this Article, we explore a range of tactical considerations that lawyers must consider—from defenses to evidentiary concerns. We also explore how damages are contemplated in the context of hazing litigation.

The Use Of Technical Experts In Software Copyright Cases: Rectifying The Ninth Circuit’S “Nutty” Rule, Shyamkrishna Balganesh, Peter Menell

All Faculty Scholarship

Courts have long been skeptical about the use of expert witnesses in copyright cases. More than four decades ago, and before Congress extended copyright law to protect computer software, the Ninth Circuit in Krofft Television Prods., Inc. v. McDonald’s Corp., ruled that expert testimony was inadmissible to determine whether Mayor McCheese and the merry band of McDonaldland characters infringed copyright protection for Wilhelmina W. Witchiepoo and the other imaginative H.R. Pufnstuf costumed characters. Since the emergence of software copyright infringement cases in the 1980s, substantially all software copyright cases have permitted expert witnesses to aid juries in understanding software …

Interactions Between Need For Cognition And Ambivalent Sexism In Jurors’ Perceptions Of Expert Credibility, Trina Iyamuremye Uwineza, Morgan Hurtz, Laurel Westerman, Erika Boohar, Kaela Meyer, Halleigh Kelchen, Sarah Eagan, Sarah Gervais

UCARE Research Products

The current study examined interactions between Need for Cognition scores (NCS) and Ambivalent Sexism scores (ASI; Hostile (HS) and Benevolent sexism (BS)) on perceptions of expert witness credibility. Participants (N = 467) with ages that ranged from 19–70 years (M=26.35, SD=9.20) completed the Need for Cognition Scale (Cacioppo & Petty, 1982), Ambivalent Sexism Inventory (Glick & Fiske, 1996), and Witness Credibility Scale (Brodsky, Griffin, & Cramer, 2010), and viewed a female expert witness providing scientific testimony in a civil trial. We hypothesized that 1) men who were low on need for cognition and high on benevolent …

Beyond The Witness: Bringing A Process Perspective, Edward K. Cheng, G. Alexander Nunn

Edward Cheng

For centuries, the foundation of the Anglo-American trial has been the witness.' Witnesses report on their personal observations, provide opinions of character, offer scientific explanations, and in the case of parties, narrate their own story. Indeed, even for documentary and other physical evidence, witnesses often provide the conduit through which such evidence reaches the factfinder. Documentary or physical evidence rarely stands on its own. The law of evidence has thus unsurprisingly focused on-or perhaps obsessed over-witnesses. The hearsay rule and the Confrontation Clause demand that declarants be available witnesses at trial so that they may be subject to cross-examination.' Expert …

Scientific Evidence And Forensic Science Since Daubert: Maine Decides To Sit Out On The Dance, Thomas L. Bohan

Maine Law Review

In 1993, the Supreme Court of the United States stated that with the federal adoption of statutory rules of evidence in 1975, the common law rule for determining admissibility of scientific testimony was superseded, and that thenceforth admissibility of scientific testimony was to be determined solely by Federal Rule of Evidence 702 (Rule 702). The Frye standard had been adopted in one form or another by most of the federal circuits and by many of the state courts during the 70 years preceding Daubert. Referred to as the “general acceptance” standard, the Frye standard--although adopted in a variety of forms--had …

We submit this brief to make three important points. First, Ake itself clearly and unambiguously held as a matter of due process that indigent capital defendants must be provided with independent expert assistance upon a reasonable showing of need. The Court was unanimous on this point and swept aside aging precedent that had held provision of neutral assistance was adequate.

Second, Ake was hardly a revolutionary decision. As the Court noted, many states already provided expert assistance. In the first six years after Ake, numerous states explicitly held independent expert assistance must be provided upon an adequate showing of need. …

Navigating Some Deep And Troubled Jurisprudential Waters: Lawyer–Expert Witnesses And The Twin Dangers Of Disguised Testimony And Disguised Advocacy, W. William Hodes

St. Mary's Journal on Legal Malpractice & Ethics

Expert testimony is indispensable to the uniquely American system of adversary justice. Without the assistance of expert witnesses with specialized knowledge, based on either science or experience and practice, jury verdicts would often be the result of pure whim and prejudice, or random and arbitrary decision-making. At the same time, the use of compensated, partisan expert witnesses poses significant dangers to the fair and just determination of disputes. This Article examines the enhanced dangers that can appear when the expert witness is a lawyer, chiefly the pervasive use of “disguised testimony” and “disguised advocacy.” The Article concludes with some suggestions …

Akron Law Review

This Comment examines the history of scientific and non-scientific expert evidence, its current status, and the future of scientific and non-scientific evidence based on recent court decisions. Part II explores the background of these issues by examining the earlier standard for admitting expert testimony, the effect of Congress’ promulgation of the Federal Rules of Evidence, and the influential cases in this area. Part III analyzes the importance of subjecting nonscientific expert testimony to the same rigors as scientific expert testimony. Lastly, Part IV predicts the future of expert evidence.

Selecting An Appropriate Damages Expert In A Patent Case; An Examination Of The Current Status Of Daubert, Michael H. King, Steven M. Evans

Akron Law Review

The determination of damages is a critical part of any patent case. As a plaintiff, maximizing awarded damages, whether financial or injunctive, is the ultimate objective of the patent case. As a defendant, minimizing or preventing any awarded damages is the ultimate objective.

Multimillion dollar verdicts in patent cases are now the norm and hundred plus million dollar verdicts are becoming more frequent. A lawyer who fails to devote sufficient time to this critical component of a case does the client a disservice.

There are generally two types of damages in patent cases: lost profits and a reasonable royalty. A …

Summary Of Logan V. Abe, 131 Nev. Adv. Op. No. 31 (Jun. 4, 2015), Michael S. Valiente

Nevada Supreme Court Summaries

A party incurs an expense even if a third party pays the expense on the party’s behalf, as long as the party would otherwise be legally obligated to pay the expense. Thus, costs and reasonable attorney fees that a third party paid on behalf of a litigant can be recovered under NRS 17.115(4) and NRCP 68(f)(2). In addition, a party can recover expert witness fees even if the expert did not testify at trial and was not deposed.

Explaining Inhumanity: The Use Of Crime-Definition Experts At International Criminal Courts, Caroline Davidson

Vanderbilt Journal of Transnational Law

International criminal courts must not only decide the guilt or innocence of defendants in immensely serious cases, but also make good law in the process. To help them do so, these courts have turned to experts. This Article identifies a type of expert witness that, thus far, has escaped scholarly attention: the crime-definition expert. Crime-definition experts have provided expert reports and testimony to international criminal courts on the meaning of the very crimes with which defendants are charged, including genocide, forced marriage, and recruitment and use of child soldiers. This Article critically evaluates the risks associated with using crime-definition experts …

Reconceptualizing The Expert Witness: Social Costs, Current Controls And Proposed Responses, Jeffrey L. Harrison

Jeffrey L Harrison

Unlike virtually any other business, expert witnesses are not typically held accountable in either tort or contract law for their commercial activities. This means that many are inclined to deliver what the market demands - partisan, biased, or plainly dishonest testimony - without concern for the costs this testimony may impose on others. This immunity from the internalization of the social cost of their testimony is hard to reconcile with any moral or economic standard. Harsh judicial reactions to some experts and a slight increase in expert witness liability may signal that a change in the privileged status of experts …
