How Florida’S Courts Should Evaluate The Admissibility Of Field Sobriety Testing And Blood Thc Levels Evidence In Marijuana Impaired Driving Prosecutions, Christopher Bomhoff
How Florida’S Courts Should Evaluate The Admissibility Of Field Sobriety Testing And Blood Thc Levels Evidence In Marijuana Impaired Driving Prosecutions, Christopher Bomhoff
FIU Law Review
Field sobriety and blood alcohol concentration tests are proven reliable techniques to determine whether a person us under the influence of alcohol. No such technique has been developed to reliably determine whether a person is under the influence of marijuana. However, despite a lack of scientific consensus regarding the reliability of field sobriety and blood toxicology tests to determine marijuana impairment, these methods are routinely used as evidence of guilt in marijuana impaired driving prosecutions. Twenty-four states have legalized the recreational use of marijuana, and Florida appears to be set to join them in the near future. As a result …

Reliability Of Expert Evidence In International Disputes, Matthew W. Swinehart
Reliability Of Expert Evidence In International Disputes, Matthew W. Swinehart
Michigan Journal of International Law
Part I of this article traces the historical trends in the use of expert evidence in international disputes, from the scattered reliance on experts in the nineteenth and early twentieth centuries to the ubiquity of experts in modern disputes. With that perspective, Part II examines how decision makers have attempted to ensure reliability of the expert evidence that is flooding the evidentiary records of international disputes, while Part III outlines the many problems that still remain. Finally, Part IV proposes a non-exhaustive and nonbinding checklist of questions for analyzing the reliability of any type of expert evidence.
Who Must Testify To The Results Of A Forensic Laboratory Test? Bullcoming V. New Mexico, Richard D. Friedman

Does the Confrontation Clause permit the prosecution to introduce a forensic laboratory report through the in-court testimony of a supervisor or other person who did not perform or observe the reported test?
Competition In The Courtroom: When Does Expert Testimony Improve Jurors’ Decisions?, Cheryl Boudreau, Mathew D. Mccubbins
Competition In The Courtroom: When Does Expert Testimony Improve Jurors’ Decisions?, Cheryl Boudreau, Mathew D. Mccubbins
Faculty Scholarship
Many scholars lament the increasing complexity of jury trials and question whether the testimony of competing experts helps unsophisticated jurors to make informed decisions. In this article, we analyze experimentally the effects that the testimony of competing experts has on (1) sophisticated versus unsophisticated subjects' decisions and (2) subjects' deci- sions on difficult versus easy problems. Our results demonstrate that competing expert testimony, by itself, does not help unsophisticated subjects to behave as though they are sophisticated, nor does it help subjects make comparable decisions on difficult and easy problems. When we impose additional institutions (such as penalties for lying …
Nothing But The Truth? Experiments On Adversarial Competition, Expert Testimony, And Decision Making, Cheryl Boudreau, Mathew D. Mccubbins
Nothing But The Truth? Experiments On Adversarial Competition, Expert Testimony, And Decision Making, Cheryl Boudreau, Mathew D. Mccubbins
Faculty Scholarship
Many scholars debate whether a competition between experts in legal, political, or economic contexts elicits truthful information and, in turn, enables people to make informed decisions. Thus, we analyze experimentally the conditions under which competition between experts induces the experts to make truthful statements and enables jurors listening to these statements to improve their decisions. Our results demonstrate that, contrary to game theoretic predictions and contrary to critics of our adversarial legal system, competition induces enough truth telling to allow jurors to improve their decisions. Then, when we impose additional institutions (such as penalties for lying or the threat of …

A Three-Dimensional Model For The Use Of Expert Psychiatric And Psychological Evidence In False Confession Defenses Before The Trier Of Fact, Major Joshua E. Kastenberg
A Three-Dimensional Model For The Use Of Expert Psychiatric And Psychological Evidence In False Confession Defenses Before The Trier Of Fact, Major Joshua E. Kastenberg
Seattle University Law Review
Part I of this Article delineates a defendant's right to present voluntariness and credibility evidence against his or her confession. This section analyzes the basic constitutional framework of how a defendant can present this evidence and describes the traditional safeguards against false confessions. This background information provides a context for the overarching issue of expert testimony admissibility. Part II provides a basic understanding of differences between the psychiatric (medical model) and psychological (social model) approach to false confessions. It then examines the types of false confession defenses used by defendants and the interrogation techniques challenged by defendants. Part III reviews …
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 …
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, …
Specialized Trial Courts: Concentrating Expertise On Fact, Arti K. Rai
Specialized Trial Courts: Concentrating Expertise On Fact, Arti K. Rai
Faculty Scholarship
In the absence of a specialized patent trial court with expertise in fact-finding, the Court of Appeals for the Federal Circuit often reviews de novo the many factual questions that pervade patent law. De novo review of fact by an appellate court is problematic. In the area of patent law, as in other areas of law, there are sound institutional justifications for the conventional division of labor that gives trial courts primary responsibility for questions of law. This Article identifies the problems created by de novo appellate review of fact and argues for the creation of a specialized trial court …

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.

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

Social Science And The Courts: The Role Of Amicus Curiae Briefs, Ronald G. Roesch, Stephen L. Golding, Valerie P. Hans, N. Dickon Reppucci
Cornell Law Faculty Publications
Social scientists have increasingly become involved in the submission of amicus curiae or "friend of the court" briefs in legal cases being decided by state and federal courts. This increase has triggered considerable debate about the use of briefs to communicate relevant social science research. This article evaluates the strengths and weaknesses of various methods of summarizing social science research for the courts. It also reviews the procedures for submitting briefs developed by the American Psychology-Law Society which, in collaboration with the American Psychological Association, has submitted its first brief in Maryland v. Craig, a case recently decided by …
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 …
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.
