Expert Information And Expert Evidence: A Preliminary Taxonomy, Samuel R. Gross, Jennifer L. Mnookin Jan 2003

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 …


Confrontation As A Hot Topic: The Virtues Of Going Back To Square One, Richard D. Friedman Jan 2003

Confrontation As A Hot Topic: The Virtues Of Going Back To Square One, Richard D. Friedman

Articles

I have been working so obsessively on the accused's right to confront the witnesses against him 1 that I am gratified that the organizers of this conference have designated confrontation as one of the "hot topics" of Evidence law. I am not so egotistical as to think that my work has made confrontation into a hot topic; I am just glad to know that I am working where a good deal of action is, and that other scholars recognize that confrontation is an important area in which dramatic changes may be occurring.


Sometimes What Everybody Thinks They Know Is True, Richard D. Friedman, Roger C. Park Jan 2003

Sometimes What Everybody Thinks They Know Is True, Richard D. Friedman, Roger C. Park

Articles

This essay responds to D. Davis and W. C. Follette (2002), who question the value of motive evidence in murder cases. They argue that the evidence that a husband had extramartial affairs, that he heavily insured his wife's life, or that he battered his wife is ordinarily of infinitesimal probative value. We disagree. To be sure, it would be foolish to predict solely on the basis of such evidence that a husband will murder his wife. However, when this kind of evidence is cobmined with other evidence in a realistic murder case, the evidence can be quite probative. We analyze …


Expert Testimony On Fingerprints: An Internet Exchange, Richard D. Friedman, David H. Kaye, Jennifer Mnookin, Dale Nance, Michael Saks Jan 2002

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.


Dial-In Testimony, Richard D. Friedman, Bridget Mary Mccormack Jan 2002

Dial-In Testimony, Richard D. Friedman, Bridget Mary Mccormack

Articles

For several hundred years, one of the great glories of the common law system of criminal justice has been the requirement that prosecution witnesses give their testimony in the presence of the accused" face to face," in the time-honored phrase-under oath, subject to cross-examination, and, unless unfeasible, in open court. In the United States, this principle is enshrined in the Confrontation Clause of the Sixth Amendment, which provides that "[i]n all criminal prosecutions, the accused shall enjoy the right ... to be confronted with the witnesses against him." But now a new way is developing for witnesses for the prosecution …


The Conundrum Of Children, Confrontation, And Hearsay, Richard D. Friedman Jan 2002

The Conundrum Of Children, Confrontation, And Hearsay, Richard D. Friedman

Articles

The adjudication of child abuse claims poses an excruciatingly difficult conundrum. The crime is a terrible one, but false convictions are abhorrent. Often the evidence does not support a finding of guilt or innocence with sufficient clarity to allow a decision free of gnawing doubt. In many cases, a large part of the problem is that the prosecution's case depends critically on the statement or testimony of a young child. Even with respect to adult witnesses, the law of hearsay and confrontation is very perplexing, as anyone who has studied American evidentiary law and read Supreme Court opinions on the …


Proposed Amendments To Fed. R. Crim. P. 26: An Exchange: Remote Testimony, Richard D. Friedman Jan 2002

Proposed Amendments To Fed. R. Crim. P. 26: An Exchange: Remote Testimony, Richard D. Friedman

Articles

Recently, the Supreme Court declined to pass on to Congress a proposed change to Federal Rule of Criminal Procedure 26 submitted to it by the Judicial Conference. In this Article, Professor Friedman addresses this proposal, which would allow for more extensive use of remote, video-based testimony at criminal trials. He agrees with the majority of the Court that the proposal raised serious problems under the Confrontation Clause. He also argues that a revised proposal, in addition to better protecting the confrontation rights of defendants, should include more definite quality standards, abandon its reliance on the definition of unavailability found in …


Experts, Carl E. Schneider Jul 2001

Experts, Carl E. Schneider

Articles

George Bernard Shaw famously said that all professions are conspiracies against the laity. Less famously, less elegantly, but at least as accurately, Andrew Abbott argued that professions are conspiracies against each other. Professions compete for authority to do work and for authority over work. The umpire in these skirmishes and sieges is the government, for the state holds the gift of monopoly and the power to regulate it. In Abbott's terms, "bioethics" is contesting medicine's power to influence the way doctors treat patients. If it follows the classic pattern, bioethics will solicit work and authority by recruiting government's power. A …


A Suggestion On Suggestion, Richard D. Friedman, Stephen J. Ceci Jan 2001

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 Jan 2000

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 …


One More Final Exam?, Edward H. Cooper Jan 2000

One More Final Exam?, Edward H. Cooper

Articles

An invitation to relive the agonies of yesteryear by taking an examination question, even a brief one, may seem easy to refuse. Admitting that the subject is Civil Procedure may seal the issue. But this question triggers a reflex that should be common to all lawyers. Try it. After thinking aobut the question - if you frame your answer without writing it out, less than 20 minutes will do - go on to the explanation of the question's origin and my own answer.


Lilly V. Virginia Glimmers Of Hope For The Confrontation Clause?, Richard D. Friedman Jan 2000

Lilly V. Virginia Glimmers Of Hope For The Confrontation Clause?, Richard D. Friedman

Articles

In 1662, in The Case of Thomas Tong and Others, which involved charges of treason against several defendants, the judges of the King's Bench conferred on a crucial set of points of procedure. As reported by one of the judges, Sir John Kelyng, the judges agreed unanimously that a pretrial confession made to the authorities was evidence against the Party himself who made the Confession, and indeed, if adequately proved could support a conviction of that party without additional witnesses to the treason itself. But -- again unanimously, and quite definitively -- the judges also agreed that the confession cannot …


Lilly V. Virginia: A Chance To Reconceptualize The Confrontation Right, Richard D. Friedman Jan 1999

Lilly V. Virginia: A Chance To Reconceptualize The Confrontation Right, Richard D. Friedman

Articles

In Lilly v. Virginia, the Supreme Court once again has the opportunity to grapple with the meaning of the Confrontation Clause of the Sixth Amendmel).t. The basic facts of Lilly are simple, for they present the ageold problem of accomplice confessions. Three men, Gary Barker and Ben and Mark Lilly, went on a crime spree, during which one of them shot to death a young man they had robbed and kidnaped. Ben Lilly was charged with being the triggerman, and Barker testified to that effect at Ben's trial. Mark did not testify. But Mark had made a statement to the …


Confrontation Confronted, Richard D. Friedman, Margaret A. Berger, Steven R. Shapiro Jan 1999

Confrontation Confronted, Richard D. Friedman, Margaret A. Berger, Steven R. Shapiro

Articles

The following article is an edited version of the amicus curiae brief filed with the Supreme Court of the United States in the October Term, 1998, in the case of Benjamin Lee Lilly v. Commonwealth of Virginia (No. 98-5881). "This case raises important questions about the meaning of the confrontation clause, which has been a vital ingredient of the fair trial right for hundreds of years," Professor Richard Friedman and his co-authors say. "In particular, this case presents the Court with an opportunity to reconsider the relationship between the confrontation clause and the law of hearsay." On June 10 the …


Lost Lives: Miscarriages Of Justice In Capital Cases, Samuel R. Gross Jan 1999

Lost Lives: Miscarriages Of Justice In Capital Cases, Samuel R. Gross

Articles

In case after case, erroneous conviction for capital murder has been proven. I contend that these are not disconnected accidents, but systematic consequences of the nature of homicice prosecution in the general and capital prosecution in particular - that in this respect, as in others, death distorts and undermines the course of the law.


Confrontation: The Search For Basic Principles, Richard D. Friedman Jan 1998

Confrontation: The Search For Basic Principles, Richard D. Friedman

Articles

The Sixth Amendment to the Constitution guarantees the accused in a criminal prosecution the right "to be confronted with the Witnesses against him."' The Confrontation Clause clearly applies to those witnesses who testify against the accused at trial. Moreover, it is clear enough that confrontation ordinarily includes the accused's right to have those witnesses brought "face-toface," in the time-honored phrase, when they testify.2 But confrontation is much more than this "face-to-face" right. It also comprehends the right to have witnesses give their testimony under oath and to subject them to crossexamination. 3 Indeed, the Supreme Court has treated the accused's …


Truth And Its Rivals In The Law Of Hearsay And Confrontation (Symposium: Truth And Its Rivals: Evidence Reform And The Goals Of Evidence Law)." , Richard D. Friedman Jan 1998

Truth And Its Rivals In The Law Of Hearsay And Confrontation (Symposium: Truth And Its Rivals: Evidence Reform And The Goals Of Evidence Law)." , Richard D. Friedman

Articles

In this paper, I will look at the problem of hearsay and confrontation through the lens offered by this symposium's theme of "truth and its rivals." I will ask: To what extent does the law of hearsay and confrontation aspire to achieve the goal of truth in litigation? To what extent does it, or should it, seek to achieve other goals, or to satisfy other constraints on the litigation system? And, given the ends that it seeks to achieve, what should the shape of the law in this area be? My principal conclusions are as follows: In most settings, the …


Confrontation And The Definition Of Chutzpa, Richard D. Friedman Jan 1997

Confrontation And The Definition Of Chutzpa, Richard D. Friedman

Articles

You may know the standard illustration of chutzpa - the man who kills both his parents and then begs the sentencing court to have mercy on an orphan. In this article, I discuss a case of chutzpa that is nearly as outlandish - the criminal defendant who, having rendered his victim unavailable to testify, contends that evidence of the victim's statement should not be admitted against him because to do so would violate his right to confront her. I contend that in a case like this the defendant should be deemed to have forfeited the confrontation right. On the same …

Probability And Proof In State V. Skipper: An Internet Exchange, Ronald J. Allen, David J. Balding, Peter Donnelly, Richard D. Friedman, David H. Kaye, Lewis Henry Larue, Roger C. Park, Bernard Robertson, Alexander Stein

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.


Prior Statements Of A Witness: A Nettlesome Corner Of The Hearsay Thicket, Richard D. Friedman Jan 1995

Prior Statements Of A Witness: A Nettlesome Corner Of The Hearsay Thicket, Richard D. Friedman

Articles

In Tome v United States, for the fifth time in eight years, the Supreme Court decided a case presenting the problem of how a child's allegations of sexual abuse should be presented in court. Often the child who charges that an adult abused her is unable to testify at trial, or at least unable to testify effectively under standard procedures. These cases therefore raise intriguing and difficult questions related to the rule against hearsay and to an accused's right under the Sixth Amendment to confront the witnesses against him. One would hardly guess that, however, from the rather arid debate …


Déjà-Vu All Over Again- Elliott's Critique Of Eyewitness Experts, Saul M. Kassin, Phoebe C. Ellsworth, Vicki L. Smith Jan 1994

Déjà-Vu All Over Again- Elliott's Critique Of Eyewitness Experts, Saul M. Kassin, Phoebe C. Ellsworth, Vicki L. Smith

Articles

Echoing McCloskey and Egeth (1983), and motivated by Kassin, Ellsworth, and Smith's (1989) survey of 63 eyewitness experts, Elliott (1993) recently attacked the use of psychological experts on eyewitness testimony. There are two principal shortcomings of this critique. First, it misrepresents the eyewitness literature and the experts who use it. Second, it merely parrots complaints of the past. The same old arguments are made about the lack of sufficient research evidence, the standards by which experts should conduct their affairs, and the impact of it all on the jury. Perhaps the field needs periodic prodding and consciousness-raising on this issue, …


The Death And Transfiguration Of Frye, Richard D. Friedman Jan 1994

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.


Toward A Partial Economic, Game-Theoretic Analysis Of Hearsay, Richard D. Friedman Jan 1992

Toward A Partial Economic, Game-Theoretic Analysis Of Hearsay, Richard D. Friedman

Articles

In this Article, I offer a fundamentally different and nondoctrinaire way of approaching hearsay questions. In brief, I take the view that the resolution of a hearsay dispute, when the declarant is not on the stand, is essentially a matter of deciding who should bear the burden of producing the declarant, or more precisely, how courts should allocate that burden. Adopting a simple procedural improvement, concerning the examination of the declarant if she is produced as a witness, allows the court to allocate the burden optimally. If live testimony by the declarant would be more probative than prejudicial, then most …


Infinite Strands, Infinitesimally Thin: Storytelling, Bayesianism, Hearsay And Other Evidence, Richard D. Friedman Jan 1992

Infinite Strands, Infinitesimally Thin: Storytelling, Bayesianism, Hearsay And Other Evidence, Richard D. Friedman

Articles

David Schum has long been one of our keenest commentators on questions of inference and proof. He has been particularly interested in, and illuminating on, the subject of "cascaded," or multi-step, inference.' This is a subject of importance to lawyers, because most evidence at trial can be analyzed in terms of cascaded inference. Usually, the proposition that the fact finder2 might immediately infer from the evidence is not itself an element of a crime, claim, or defense. Most often, an extra inference would be required to jump from that proposition to a proposition that the law deems material. Thus, inference …


Telling Tales In Court: Trial Procedure And The Story Model, Richard O. Lempert Nov 1991

Telling Tales In Court: Trial Procedure And The Story Model, Richard O. Lempert

Articles

There are three ways in which stories may figure prominently at trials. First, litigants may tell stories to jurors. Not only is there some social science evidence that this happens, but trial lawyers have an instinctive sense that this is what they do. Ask a litigator to describe a current case and she is likely to reply, "Our story is ... " Second, jurors may try to make sense of the evidence they receive by fitting it to some story pattern. If so, the process is likely to feed back on itself. That is, jurors are likely to build a …


Improving The Procedure For Resolving Hearsay Issues, Richard D. Friedman Jan 1991

Improving The Procedure For Resolving Hearsay Issues, Richard D. Friedman

Articles

In this article, I propose two changes in the way hearsay issues are usually resolved. First, in some circumstances courts should divide the burdens of producing the declarant-for example, by imposing the physical burden on the proponent and the financial burden on the opponent. Second, no matter how the declarant is produced as a witness, she should ordinarily testify as part of the proponent's case, subject to cross-examination by the opponent. If the declarant does become a witness, the admissibility of her out-of-court statement should not be resolved until her current testimony about the underlying events is received.


Expert Evidence, Samuel R. Gross Jan 1991

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 …


Clinical Realism: Simulated Hearings Based On Actual Events In Students' Lives, Samuel R. Gross Jan 1990

Clinical Realism: Simulated Hearings Based On Actual Events In Students' Lives, Samuel R. Gross

Articles

This essay describes a novel clinical format, a simulation course that is based on students' testimony about actual events in their own lives. The two main purposes of the course, however, are not novel. First, I aim to teach the students to be effective trial lawyers by instructing them in the techniques of direct examination and cross-examination and by making them sensitive to the roles of the other courtroom players: the witness, the judge, and the jury. Second, I hope to encourage the students to think about the social and ethical consequences of our method of trying lawsuits.


Loss Of Innocence: Eyewitness Identification And Proof Of Guilt, Samuel R. Gross Jan 1987

Loss Of Innocence: Eyewitness Identification And Proof Of Guilt, Samuel R. Gross

Articles

It is no news that eyewitness identification in criminal cases is a problem; it is an old and famous problem. Judges and lawyers have long known that the identification of strangers is a chancy matter, and nearly a century of psychological research has confirmed this skeptical view. In 1967 the Supreme Court attempted to mitigate the problem by regulating the use of eyewitness identification evidence in criminal trials; since then it has retreated part way from that effort. Legal scholars have written a small library of books and articles on this problem, the courts' response to it, and various proposed …
