Blending Criminal Procedure At The Ad Hoc Tribunals, William A. Schabas

Michigan Journal of International Law

Review of International Criminal Evidence by Richard May & Marieke Wierda

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, …

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 …

Crawford V. Washington, Richard D. Friedman

Articles

On June 9, by granting certiorari in Crawford v. Washington, 02-9410, the Supreme Court signaled its intention to enter once again into the realm of the Confrontation Clause, in which it has found itself deeply perplexed. This time there was a difference, however, because the grant indicated that the Court might be willing to rethink its jurisprudence in this area. Crawford, like Lee v. Illinois, 476 U.S. 530 (1986), and Lilly v. Virginia, 527 U.S. 116 (1999), presents a classic case of what might be called station-house testimony. Michael Crawford was accused of stabbing another man. His wife, Sylvia, was …

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 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 …

Weighing Poison Fruit, Yale Kamisar

Articles

In the simplest cases involving the exclusion of illegally obtained evidence, the items the defense is trying to suppress, such as drugs found during the search of a suspect's pocket, are direct, or primary, in their relationship to the police action. Thus, if the police have acted unlawfully, the evidence must be excluded from trial.

Many times, however, evidence is derivative, or secondary, in character. For example, an illegal search may turn up a key to an airport locker where the proceeds of a bank robbery are being kept. Or a coerced confession may reveal the place where a suspect …

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.

A Resident Of Evidenceland Defends His Turf, Richard D. Friedman

Articles

A few years ago, I wrote an essay welcoming Judge Richard Posner down from a star to Evidenceland, the sometimes obscure province occupied by evidence scholars.1 Although I criticized one of the points of his article on the economics of evidence law, I expressed the hope that he would remain in Evidenceland for an extended stay.2 I should have known that if he did so he would tell us long-term inhabitants what we have been doing wrong.

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, …

In Defense Of The Search And Seizure Exclusionary Rule (Law And Truth - The Twenty-First Annual National Student Federalist Society Symposium On Law And Public Policy - 2002), Yale Kamisar

Articles

think Dean Pye's advice about casebook writing was sound,6 and what he had to say also applies to discussions and debates about such issues as the search and seizure exclusionary rule. We cannot (at least we should not) begin with Mapp v. Ohio. We need a prelude.

Computer Searches And Seizures: Some Unresolved Issues, Susan W. Brenner, Barbara A. Frederiksen

Michigan Telecommunications & Technology Law Review

The goal of this article is to illustrate the issues that arise in the context of computer search and seizures by examining several areas in which the application of Fourth Amendment concepts to computer searches and/or seizures can be problematic. In order to illustrate this point, the article will build on a hypothetical. The hypothetical situation assumes law enforcement officers have lawfully obtained a warrant to search for and seize evidence concerning the commission of one or more crimes. It will also be assumed that computer technology played some role in the commission of these crimes, so computer equipment and …

Proposed Amendments To Fed. R. Crim. P. 26: An Exchange: Remote Testimony - A Prosecutor's Perspective, Lynn Helland

University of Michigan Journal of Law Reform

Although the Supreme Court has declined, for now, to endorse the Judicial Conference proposal to add a Rule 26(b) of the Federal Rules of Criminal Procedure to permit live video testimony under limited circumstances, I agree with Professor Friedman that the matter is far from over. This is both because the potential benefits to be realized from the use of remote video testimony are too large to ignore and because, on closer inspection, any Confrontation Clause concerns that might underlie the Court's hesitation to adopt the proposal are not warranted. My purpose in writing is to summarize some of the …

The Legal Context And Contributions Of Dostoevsky's Crime And Punishment, William Burnham

Michigan Law Review

Dostoevsky's Crime and Punishment is of more than average interest to lawyers. The title perhaps says it all in terms of content. The chief protagonist, the murderer Raskolnikov, is a law student on a break from his studies. And the pursuer of the murderer is a lawyer, an examining magistrate. But the more subtle and more important legal aspects of Crime and Punishment concern the time period in Russian legal history in which the novel was written and is set. The 1860s in Russia were a time of tremendous legal change. Among other things, an 1861 decree emancipated the serfs …

No Link: The Jury And The Origins Of The Confrontation Right And The Hearsay Rule, Richard D. Friedman

Book Chapters

The rule against hearsay has long been one of the most distinctive elements of the common law of evidence, and indeed— except for recent changes on the civil side in many jurisdictions— of the common law system of trial. Observers have long believed that the rule, like most of the other exclusionary rules of the common law of evidence, is "the child of the jury system". Though Edmund Morgan argued vigorously to the contrary, the received understanding is that the jury's inability to account satisfactorily for the defects of hearsay explains the rule. A famous, and perhaps seminal, expression of …

Confessions, Search And Seizure, And The Rehnquist Court, Yale Kamisar

Book Chapters

About the time William Rehnquist ascended to the Chief Justiceship of the United States, two events occurred that increased the likelihood that Miranda would enjoy a long life.

In Moran v. Burbine, a six to three majority held that a confession preceded by an otherwise valid waiver of a suspect's Miranda rights should not be excluded either (1) because the police misled an inquiring attorney when they told her they were not going to question the suspect she called about or (2) because the police failed to inform the suspect of the attorney's efforts to reach him.

Although Burbine has …

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 …

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.

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 …

Cross-Examining Expertise In The Wto Dispute Settlement Process, Christopher T. Timura

Michigan Journal of International Law

Part I of this Note surveys some of the recent contributions that social theorists and social scientists have made to our understanding of the role of experts in society, and also the structure of expert communities. Experts are everywhere in modern life, and individuals are with increasing frequency asked to extend their trust to experts and bodies of knowledge that they have little or no opportunity to question. Part II highlights how the WTO Agreement deals with experts, using recent WTO panel reports to illustrate the ways in which the DSB has operationalized its various provisions. Part III suggests two …

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 …

Narrative Relevance, Imagined Juries, And A Supreme Court Inspired Agenda For Jury Research, Richard O. Lempert

Articles

This paper has its roots in Old Chief v. United States, a case the Supreme Court of the United States decided in 1997. I will begin by describing this case; then comment on its implications for the Supreme Court’s conception of the jury, and conclude by examining the agenda one may draw from it for empirical jury research. Old Chief arose when Johnny Lynn Old Chief was charged not only with assault with a dangerous weapon and using a firearm in the commission of a crime of violence, but also with violating a law that forbids convicted felons from possessing …

A Very Brief Primer On Bayesian Methods In Evidence, Richard D. Friedman

Articles

I have been asked to write an extremely short explanation of the Bayesian approach to evidentiary issues, for the benefit of those who regard themselves as probabilistically challenged. Although the application of Bayesian probability to evidence has generated a good deal of debate, its use as a heuristic device should not be particularly controversial. Evidence concerns propositions that are uncertain. Accordingly, some concept of probability must play a role. Standards of persuasion, such as "more likely than not" and "beyond a reasonable doubt" are clearly probabilistic, and the definition of relevant evidence, as expressed in Fed. R. Evid. 40 I, …

The Economic Analysis Of Evidence Law: Common Sense On Stilts, Richard O. Lempert

Articles

There was a time when the empire of Law was not overrun by economists. The economists had their own fiefdoms to be sure-there was the Duchy of Antitrust and the Kingdom of Regulatory Law-but the economists lived in peace within these borders, welcoming many unlike themselves into their midst, only gently proselytizing their students in the first few classes of a term, and swearing fealty to the law. It is true that a few marauders from beyond the borders saw the wealth of the empire and sought to colonize it, but even the most daring, Archbishop Coase and Duke Gary …

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 …

Title Vii Quid Pro Quo And Hostile Environment Sexual Harassment Claims: Changing The Legal Framework Courts Use To Determine Whether Challenged Conduct Is Unwelcome, Elsie Mata

University of Michigan Journal of Law Reform

In examining the nature of sexual harassment claims, the author challenges the use of the "unwelcomeness" element to distinguish actionable conduct from nonactionable conduct. The author contends that the "unwelcomeness" element demeans women in two ways: (1) it assumes the male perspective and presumes that the plaintiff appreciated the challenged conduct unless she proves otherwise; and (2) it allows the defense to engage in intrusive, irrelevant, and damaging inquiries as it attempts to refute the plaintiff's allegation that the challenged conduct was unwelcome.

The author argues for three reforms. First, courts should shift the burden of proving that the challenged …

Conjunction And Aggregation, Saul Levmore

Michigan Law Review

This Article begins with the puzzle of why the law avoids the issue of conjunctive probability. Mathematically inclined observers might, for example, employ the "product rule," multiplying the probabilities associated with several events or requirements in order to assess a combined likelihood, but judges and lawyers seem otherwise inclined. Courts and statutes might be explicit about the manner in which multiple requirements should be combined, but they are not. Thus, it is often unclear whether a factfinder should assess if condition A was more likely than not to be present - and then go on to see whether condition B …

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 …

E' Is For Eclectic: Multiple Perspectives On Evidence (Symposium: New Perspectives On Evidence), Richard D. Friedman

Articles

A conference titled "New Perspectives on Evidence: Experts, Empirical Study and Economics" has a pronounced alliterative theme, a theme made even more apparent when, inevitably in evidentiary discourse, epistemological questions come to the fore. It is enough to make one suspect that the conference is secretly brought to you by the letter "E," hiding behind its public front, the Olin Foundation. Putting aside such conspiratorial thoughts, all these "E's" suggest the presence of a meta-"E"-Eclecticism. Indeed, I believe this conference has demonstrated the need for an eclectic approach to evidentiary problems. That should be no surprise. The domain of evidentiary …

Miranda And Some Puzzles Of 'Prophylactic' Rules, Evan H. Caminker

Articles

Constitutional law scholars have long observed that many doctrinal rules established by courts to protect constitutional rights seem to "overprotect" those rights, in the sense that they give greater protection to individuals than those rights, as abstractly understood, seem to require.' Such doctrinal rules are typically called "prophylactic" rules.2 Perhaps the most famous, or infamous, example of such a rule is Miranda v. Arizona,' in which the Supreme Court implemented the Fifth Amendment's privilege against self-incrimination4 with a detailed set of directions for law enforcement officers conducting custodial interrogations, colloquially called the Miranda warnings. 5
