Response: Exaggerated And Misleading Reports Of The Death Of Conditional Relevance, Peter Tillers

Michigan Law Review

In 1980 the late Professor Vaughn C. Ball of the University of Georgia published an article called The Myth of Conditional Relevancy. Ball's article is widely admired. One well-known evidence scholar, Ronald J. Allen, liked Ball's article so much that he borrowed its title word for word. Although the extent of Allen's enthusiasm for Ball's analysis may be unmatched, a good number of students of evidence - including this writer - have said that Ball's analysis of conditional relevance is both original and important. Richard Friedman, by contrast, cannot be counted as one of Ball's more ardent admirers. Although Friedman …

Conditional Probative Value: Neoclassicism Without Myth, Richard D. Friedman

Articles

The concept of conditional relevance is an essential aspect of the classical model of evidentiary law. Some of the great scholars of evidence have endorsed and shaped it.1 Under Federal Rule of Evidence 104(b) it plays a crucial role in the division of responsibility between judge and jury,2 as well as in the application of the personal knowledge3 and authentication 4 requirements. And the Supreme Court has applied it with great force.5 In recent years, though, the concept has come under attack from several notable scholars. The late Vaughn Ball led the assault, calling the concept a "myth."'6 Peter Tillers, …

Comment: Theory And Practice In Dna Fingerprinting, Richard O. Lempert

Articles

Throughout her useful paper on DNA identification, Professor Roeder properly attends to both theory and practice. Thus she acknowledges the theoretical soundness of certain criticisms that have been made of the standard paradigm used to evaluate DNA random match probabilities but argues that in practice these criticisms matter little. I am thinking here of the arguments that those cautioning against overweighing DNA evidence have made regarding the undeniable existence of population substructure and its potential implications for independence assumptions supporting the application of the product rule and for the use of convenience samples, such as data garnered from no more …

Character Impeachment Evidence: The Asymmetrical Interaction Between Personality And Situation, Richard D. Friedman

Articles

In Part I of this Comment, I present a short version of my argument against the admissibility of character impeachment evidence of criminal defendants, showing how the key elements ofthis argument are present in Professor Uviller's own Article. In Part II, I suggest that, notwithstanding Professor Uviller's comments to the contrary, an asymmetrical result-never admitting character evidence to impeach criminal defendants but admitting such evidence in some circumstances to impeach other witnesses- is perfectly reasonable. Finally, in Part III, I contend that Professor Uviller's interesting judicial surveys support the solution I have proposed for the problem of character impeachment evidence.

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.

Experts, Stories, And Information, Richard O. Lempert

Articles

In the infancy of the jury trial, there were no witnesses. The jury was self-informing. Members of the jury were drawn from the community. It was expected that they would know, either firsthand or on the basis of what they had heard, the true facts of any disputed incident, and they were gathered together to say what those facts were. Ronald Allen and Joseph Miller, in their insightful paper, see the ideal of the self-informing jury as very much alive today. Allen and Miller tell us that jurors ideally should experience firsthand the factual information needed to arrive at rational …

The Suspect Population And Dna Identification, Richard O. Lempert

Articles

Forensic DNA analysis typically proceeds by first determining whether alleles (one of two or more alternative forms of a gene) found in DNA apparently left by the perpetrator of a crime at a crime scene (the "evidence sample") match alleles extracted from a sample of the suspected criminal's blood (the "suspect sample"). If alleles drawn from the two sources match, the next step is to provide information about the probative value of the match by estimating the probability that alleles extracted from the blood of some random individual would have matched the alleles in the evidence sample. Thinking in terms …

Dna, Science And The Law: Two Cheers For The Ceiling Principle, Richard O. Lempert

Articles

The ceiling principle is an intentionally conservative way of estimating the frequency with which individuals who share particular alleles appear in the general population. It establishes frequencies for each allele by taking random samples of 100 individuals from each of 15 to 20 populations and using the largest frequency with which the allele is found in any of these populations or 5 percent, whichever is larger, as an estimate of the allele's frequency in the population of interest. These frequencies are then multiplied to yield an estimate of the likelihood that a randomly selected person would exhibit the same allelic …

Toward A Liberal Application Of The "Close Of All The Evidence" Requirement Of Rule 50(B) Of The Federal Rules Of Civil Procedure: Embracing Fairness Over Formalism, Rollin A. Ransom

Michigan Law Review

This Note examines the language and purposes of rule 50 to determine if and when a relaxed application of its requirements is appropriate. Part I considers the terms and goal of the rule and concludes that its purpose is to put the party opposing the motion for judgment as a matter of law on notice of the movant's assertion that the evidence is insufficient as a matter of law, and to provide the opposing party an opportunity to "cure." Part II discusses courts' varying application of the requirement that a motion for judgment as a matter of law made at …

The Sexual Innocence Inference Theory As A Basis For The Admissibility Of A Child Molestation Victim's Prior Sexual Conduct, Christopher B. Reid

Michigan Law Review

The sexual innocence inference refers to the thought process a jury follows when it hears a young child testify about sexual acts and matters that reveal an understanding of such acts beyond the capacity likely at his or her age. A jury is likely to assume that because the child is so young, he or she must be innocent of sexual matters. Shocked by the child's display on the witness stand, the jury may then infer that the child could have acquired such knowledge only if the charged offense of child molestation is true. To rebut this inference, a defendant …

The Emerging International Consensus As To Criminal Procedure Rules, Craig M. Bradley

Michigan Journal of International Law

This article will demonstrate that these general claims, as well as certain observations about specific countries, were, with one significant exception, substantially wrong when they were written. More importantly, due to significant developments in several countries in the years since those reports came out, they are even more wrong now. That is, not only have the U.S. concepts of pre-interrogation warnings to suspects, a search warrant requirement, and the use of an exclusionary remedy to deter police misconduct been widely adopted, but in many cases other countries have gone beyond the U.S. requirements.

Burdens Of Proof, Jose E. Alvarez

Michigan Journal of International Law

Review of the book Fact-Finding Before International Tribunals edited by Richard B. Lillich

Some Steps Between Attitudes And Verdicts, Phoebe C. Ellsworth

Book Chapters

Most research that has attempted to predict verdict preferences on the basis of stable juror characteristics, such as attitudes and personality traits, has found that individual differences among jurors are not very useful predictors, accounting for only a small proportion of the variance in verdict choices. Some commentators have therefore concluded that verdicts are overwhelmingly accounted for by "the weight of the evidence," and that differences among jurors have negligible effects. But there is a paradox here: In most cases the weight of the evidence is insufficient to produce firstballot unanimity in the jury (Hans & Vidmar, 1986; Hastie, Penrod, …

Standards Of Persuasion And The Distinction Between Fact And Law, Richard D. Friedman

Articles

The invitation to respond in these pages to Gary Lawson's very interesting article, Proving the Law, was tempting enough. But what made it irresistible was Professor Lawson's comment that he is "addressing, with a brevity that borders on the irresponsible, subjects well beyond [his] depth." Now, that's the kind of debate I really like. Let me jump right in. A principal question raised by Lawson, which I find quite interesting, may be phrased in general, and purposefully ambiguous, terms as follows: Before an actor treats a proposition as a valid2 proposition of law, what standard of persuasion should that proposition …

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 …

Evidentiary Rules And Rulings: The Role Of Treatises, Richard D. Friedman

Articles

I have devoted large gobs of time to work on a multi-author treatise on the law of evidence.' And before even one volume is published, I will devote further multiple gobs of time to the project-which, perhaps audaciously and perhaps merely foolishly, but with heredity and precedent on our side,2 we are calling The New Wigmore. Accordingly, I found the question posed by this symposium-Does Evidence Law Matter?-rather disquieting. If it is doubtful even whether the law of evidence matters, then how much can a treatise on the law of evidence matter, and how worthwhile can such a work be? …

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 …

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 …

Some Caveats Concerning Dna As Criminal Identification Evidence: With Thanks To The Reverend Bayes, Richard O. Lempert

Articles

The conference panel at which this paper was originally presented was structured along the lines of a debate. The three speakers who were supposed to advocate the use of DNA evidence were labeled, as is customary, Proponents. But those who were supposed to take the negative side were not called Opponents. Rather they were labeled Caveators. I do not know who is responsible for this label, but I think it gets things exactly right. To my mind anyone considering DNA as criminal identification evidence should be a Caveator. The promise and utility of DNA analysis in identifying the perpetrators of …

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 …

Character Impeachment Evidence: Psycho-Bayesian (!?) Analysis And A Proposed Overhaul, Richard D. Friedman

Articles

Typically, arguments for restricting character impeachment evidence are based in part on the premise that prior crimes, at least violent crimes, generally indicate little about a person's veracity. The argument advanced here against character impeachment of criminal defendants does not rely on that premise; in fact, it accepts the premise that prior antisocial behavior, even not involving dishonesty, often does indicate a good deal about a person's general truthtelling inclination. A careful analysis of the situation of the accused on the witness stand-rather than an easy assumption about irrelevance-leads to this Article's broad conclusion that character impeachment evidence of criminal …

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.

Errors In Good Faith: The Leon Exception Six Years Later, David Clark Esseks

Michigan Law Review

Given this vast literature on the good faith exception, little room appears to exist for additional commentary on the propriety of the decision, its theoretical weaknesses or strengths, or what further changes in constitutional criminal procedure it forebodes. This Note will not add to the many voices complaining of the Court's misconstrual of the grounding of the exclusionary rule, nor of its crabbed notion of deterrence. Instead, it accepts, arguendo, the propriety of the exception and its underlying purpose, and then examines the six-year experience with the revised rule. The proliferation of reported applications of the good faith exception …

Remembering The 'Old World' Of Criminal Procedure: A Reply To Professor Grano, Yale Kamisar

Articles

When I graduated from high school in 1961, the "old world" of criminal procedure still existed, albeit in its waning days; when I graduated from law school in 1968, circa the time most of today's first-year law students were arriving on the scene, the "new world" had fully dislodged the old. Indeed, the force of the new world's revolutionary impetus already had crested. Some of the change that the criminal procedure revolution effected was for the better, but much of it, at least as some of us see it, was decidedly for the worse. My students, however, cannot make the …

The Search And Seizure Exclusionary Rule, Department Of Justice Office Of Legal Policy

University of Michigan Journal of Law Reform

The fourth amendment guarantees the "right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures." This guaranty is not self-executing, however, and the courts and criminal justice systems in this country have long been bedeviled by questions concerning appropriate methods of ensuring its observance. As a result of the Supreme Court's decisions in Weeks v. United States and Mapp v. Ohio, the method principally relied upon today is a judicially created rule excluding from criminal trials evidence obtained in violation of the defendant's fourth amendment rights.
