Controlling The Jury-Teaching Function, Richard D. Friedman
Controlling The Jury-Teaching Function, Richard D. Friedman
Articles
When evidence with a scientific basis is offered, two fundamental questions arise. First, should it be admitted? Second, if so, how should it be assessed? There are numerous participants who might play a role in deciding these questions—the jury (on the second question only), the parties (through counsel), expert witnesses on each side, the trial court, the forces controlling the judicial system (which include, but are not limited to, the appellate courts), and the scientific establishment. In this Article, I will suggest that together, the last two—the forces controlling the judicial system and the scientific establishment—have a large role to …
A Match Made On Earth: Getting Real About Science And The Law, Susan Haack
A Match Made On Earth: Getting Real About Science And The Law, Susan Haack
Articles
Modern legal systems increasingly depend on scientific testimony; but they also need somehow to ensure, so far as possible, that fact-finders aren't misled by highly speculative, poorly-conducted, or dishonestly-presented science. The Critical Common-sensist understanding of science that the author has developed in Defending Science and elsewhere sheds some light on why these interactions between law and science have proven so problematic. But Ms. Acharya's approach to these difficult issues rests on a flawed conception of the supposed "scientific method, " and an idea of legal "legitimacy" too weak to bear the weight she places on it; and her claim that …
Shaken Baby Syndrome, Abusive Head Trauma, And Actual Innocence: Getting It Right, Keith A. Findley, Patrick D. Barnes, David A. Moran, Waney Squier
Shaken Baby Syndrome, Abusive Head Trauma, And Actual Innocence: Getting It Right, Keith A. Findley, Patrick D. Barnes, David A. Moran, Waney Squier
Articles
In the past decade, the existence of shaken baby syndrome (SBS) has been called into serious question by biomechanical studies, the medical and legal literature, and the media. As a result of these questions, SBS has been renamed abusive head trauma (AHT). This is, however, primarily a terminological shift: like SBS, AHT refers to the two-part hypothesis that one can reliably diagnose shaking or abuse from three internal findings (subdural hemorrhage, retinal hemorrhage, and encephalopathy) and that one can identify the perpetrator based on the onset of symptoms. Over the past decade, we have learned that this hypothesis fits poorly …

Gatekeeping, Peter B. Oh
Gatekeeping, Peter B. Oh
Articles
Gatekeeping is a metaphor ubiquitous across disciplines and within fields of law. Generally, gatekeeping comprises an actor monitoring the quality of information, products, or services. Specific conceptions of gatekeeping functions have arisen independently within corporate and evidentiary law. Corporate gatekeeping entails deciding whether to grant or withhold support necessary for financial disclosure; evidentiary gatekeeping entails assessing whether expert knowledge is relevant and reliable for admissibility. This article is the first to identify substantive parallels between gatekeeping in these two contexts and to suggest their cross-treatment. Public corporate gatekeepers, like their judicial evidentiary analogues, should bear a duty of reliable monitoring.

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 …
Squeezing Daubert Out Of The Picture, Richard D. Friedman
Squeezing Daubert Out Of The Picture, Richard D. Friedman
Articles
In this essay, I will offer some thoughts on how we might reframe the issues governing the admissibility of expert evidence. My principal focus is not on any particular type of expert evidence but on broader questions: the extent to which we ought to rely on rulings of admissibility, the standards that should govern admissibility rulings, and the role of the trial and appellate courts in making those rulings. To some extent, I will concentrate on the context of criminal cases, but for the most part my conclusions apply in both civil and criminal litigation. Here are my conclusions: First, …
Minimizing The Jury Over-Valuation Concern (Visions Of Rationality In Evidence Law Symposium), Richard D. Friedman
Minimizing The Jury Over-Valuation Concern (Visions Of Rationality In Evidence Law Symposium), Richard D. Friedman
Articles
A great deal of the rhetoric of evidence discourse concerns the supposed cognitive inadequacies of the jury. In various contexts we are told that although an item of evidence is probative, it must be excluded because the jury will give it too much weight. I believe this approach has played far too great a role in evidentiary law, and that it is an interesting project to see whether we can construct a satisfactory body of law without relying at all on the cognitive inadequacy argument. I think that, at least to a large extent, we can. In some settings, where …

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.
A Suggestion On Suggestion, Richard D. Friedman, Stephen J. Ceci
A Suggestion On Suggestion, Richard D. Friedman, Stephen J. Ceci
Articles
Part I of the full article briefly describes the history and current slate of research into children's suggestibility. In this part, we argue that, although psychological researchers disagree considerably over the degree to which he suggestibility of young children may lead to false allegations of sexual abuse, there is an overwhelming consensus that children are suggestible to a degree that, we believe, must be regarded as significant. In presenting this argument, we respond to the contentions of revisionist scholars, particularly those recently expressed by Professor Lyon. We show that there is good reason to believe the use of highly suggestive …
The Suggestibility Of Children: Scientific Research And Legal Implications, Stephen J. Ceci, Richard D. Friedman
The Suggestibility Of Children: Scientific Research And Legal Implications, Stephen J. Ceci, Richard D. Friedman
Articles
In this Article, Professors Ceci and Friedman analyze psychological studies on children's suggestibility and find a broad consensus that young children are suggestible to a significant degree. Studies confirm that interviewers commonly use suggestive interviewing techniques that exacerbate this suggestibility, creating a significant risk in some forensic contexts-notably but not exclusively those of suspected child abuse-that children will make false assertions of fact. Professors Ceci and Friedman address the implications of this difficulty for the legal system and respond to Professor Lyon's criticism of this view recently articulated in the Cornell Law Review. Using Bayesian probability theory, Professors Ceci and …

Articles
This is not a conventional article. It is an edited version of messages sent to an Internet discussion list. The listings begin with the mention of a recent opinion of the Connecticut Supreme Court, parts of which are reproduced below. The listings soon move to broader issues concerning probability and other formal systems, their limitations, and their uses either in court or as devices for understanding legal proof.
The Death And Transfiguration Of Frye, Richard D. Friedman
The Death And Transfiguration Of Frye, Richard D. Friedman
Articles
The rule of Frye v. United States was seventy years old, and had long dominated American law on the question of how well established a scientific principle must be for it to provide the basis for expert testimony. Even after the passage of the Federal Rules of Evidence, several of the federal circuits, as well as various states, purported to adhere to Frye's "general acceptance" standard. But now, unanimously, briefly, and with no apparent angst, the United States Supreme Court has held in Daubert v. Merrell Dow Pharmaceuticals, Inc. that the Frye rule is incompatible with the Federal Rules.
Expert Evidence, Samuel R. Gross
Expert Evidence, Samuel R. Gross
Articles
It seems that the use of expert witnesses in common law courts has always been troublesome. In his Treatise on the Law of Evidence, first published in 1848, Judge John Pitt Taylor describes several classes of witnesses whose testimony should be viewed with caution, including: enslaved people (which accounts for "the lamentable neglect of truth, which is evinced by most of the nations of India, by the subjects of the Czar, and by many of the peasantry in Ireland"); women (because they are more susceptible to "an innate vain love of the marvelous"); and "foreigners and others ... living out …
A Review Of The Proposed Michigan Rules Of Evidence, James K. Robinson, John W. Reed
A Review Of The Proposed Michigan Rules Of Evidence, James K. Robinson, John W. Reed
Articles
On January 6, 1977, the Supreme Court of Michigan entered an order stating that it is considering adoption of the proposed Michigan Rules of Evidence which were submitted to the Court by the committee which it appointed in March 1975. The Court has solicited comments from interested persons regarding the proposed rules. A copy of the Supreme Court's order is published in this issue of the Bar Journal. The proposed rules are published in the January 26, 1977, issue of North Western Reporter, Second Series (Michigan Edition). The purpose of this article is to review in general the background and …

Witness--Competency Of An Allopathic Expert In The Field Of Homeopathy--Opinion On Very Fact The Jury Must Determine, Victor H. Lane
Articles
Van Sickle v. Doolittle, (Ia., 1918), 169 N. W. 141, was an action for malpractice against a physician of the homeopathic school of medicine. Upon the trial, a physician of the allopathic school was called, and after testifying that he was unskilled in the science of homeopathy, was allowed to testify that the treatment shown to have been given to the patient by defendant, would produce no physiological effect, and that proper treatment required the giving of such medicines as would produce such effect. This was held error upon the ground that the defendant was called to treat the patient …
The Compensation Of Medical Witnesses, Harry B. Hutchins
The Compensation Of Medical Witnesses, Harry B. Hutchins
Articles
The power to compel testimony is inherent in every court, for without it justice could constantly be thwarted. Generally all persons may be compelled to give evidence that is relevant to the matter in controversy. If, therefore, a person who has been duly summoned as a witness at a particular trial absents himself therefrom, without just cause, or attending, refuses to give evidence or to answer questions when directed so to do by the court, he is liable to punishment for contempt.1 But there are limitations upon the general rule, some based upon principles of legal policy and some upon …
Examination Of The Medical Expert, Harry B. Hutchins
Examination Of The Medical Expert, Harry B. Hutchins
Articles
The expert witness differs essentially from the ordinary witness in at least two particulars; first, in that the field of his testimony is outside the range of ordinary knowledge and experience; and, secondly, in that his testimony in the great majority of cases is in the form of opinions or conclusions that are deemed necessary for the proper guidance of the jury. It goes without saying that the 'lawyer who undertakes the examination of the expert should have such familiarity with the subject of inquiry as will enable him to develop it through the expert logically and clearly, but unfortunately …
The Physician As An Expert, Harry B. Hutchins
The Physician As An Expert, Harry B. Hutchins
Articles
Expert evidence is evidence of a scientific or technical character in regard to a matter that is outside the domain of ordinary experience and knowledge. The evidence is usually in the form of opinions or conclusions based upon facts that for the purposes of an opinion are assumed to be true, although it may be in regard to scientific facts. The expert is one who has had special training or opportunities in a particular subject that the ordinary witness has not enjoyed, and who has thereby acquired certain habits of judgment.that render his explanations and opinions in the field of …
Compensation Of Experts, Henry W. Rogers
Compensation Of Experts, Henry W. Rogers
Articles
The law relating to the compensation of experts is somewhat unsettled, and the cases are not numerous in which the subject has been considered. This very fact, however, lends additional interest to the subject, and the question is one of great importance. In some of the States the law expressly provides that when a witness is summoned to testify as an expert he shall be entitled to extra compensation. Such a provision may be found in the laws of Iowa, of North Carolina, and of Rhode Island.
