The Wrong Decision At The Wrong Time: Utah V. Strieff In The Era Of Aggressive Policing, Julian A. Cook

Scholarly Works

On June 20, 2016, the United States Supreme Court held in Utah v. Strieff that evidence discovered incident to an unconstitutional arrest of an individual should not be suppressed given that the subsequent discovery of an outstanding warrant attenuated the taint from the unlawful detention. Approximately two weeks later the issue of aggressive policing was again thrust into the national spotlight when two African-American individuals — Alton Sterling and Philando Castile — were killed by policemen in Baton Rouge, Louisiana and Falcon Heights, Minnesota, respectively, under questionable circumstances. Though connected by proximity in time, this article will demonstrate that these …

Decision Making And The Law: Truth Barriers, Jonathan J. Koehler, John B. Meixner Jr.

Scholarly Works

Reaching an accurate outcome is a central goal of the American trial. But structural features of the legal system, in combination with the cognitive shortcomings of legal actors, hinder the search for truth. Regarding the legal system, various rules and policies restrict decision makers’ access to evidence, violate the laws of probability, and limit the evidentiary concerns that may be considered on appeal. Regarding legal actors, informational deficits (particularly regarding scientific and statistical evidence) and cognitive biases of police investigators, witnesses (lay and expert), attorneys, judges, and jurors pose serious obstacles. We conclude by suggesting that research in judgment and …

Unconstitutionality And The Rule Of Wide-Open Cross-Examination: Encroaching On The Fifth Amendment When Examining The Accused, Ronald L. Carlson, Michael S. Carlson

Scholarly Works

When Georgia adopted a new evidence code on January 1, 2013, it embraced the rule on scope of cross-examination which local courts have traditionally followed. This is the wide-open rule which permits the cross-examiner to range across the entire case, no matter how limited the direct exam. Subjects foreign to the direct can be freely explored, limited only by the rule of relevancy.

Commentators have associated the majority, more limited cross-examination methodology with American jurisprudence and the wide-ranging approach with English courts. Reflecting this divide, the Supreme Court of South Dakota recognized "two principal schools of thought" when it comes …

The Hidden Daubert Factor: How Judges Use Error Rates In Assessing Scientific Evidence, John B. Meixner Jr., Shari Seidman Diamond

Scholarly Works

In Daubert v. Merrell Dow Pharmaceuticals, the United States Supreme Court provided a framework under which trial judges must assess the evidentiary reliability of scientific evidence whose admissibility is challenged. One factor of the Daubert test, the “known or potential rate of error” of the expert’s method, has received considerably less scholarly attention than the other factors, and past empirical study has indicated that judges have a difficult time understanding the factor and use it less frequently in their analyses as compared to other factors. In this paper, we examine one possible interpretation of the “known or potential rate of …

Teaching “The Wire”: Crime, Evidence, And Kids, Andrea L. Dennis

Scholarly Works

I have a confession: I have only watched Season 1 of The Wire, and it has been many years since I did that. Thus, both my knowledge and pedagogical use of the show are limited. What explanation can I offer for my failings? I am a Maryland native with family who resides in Baltimore City, or Charm City as it is affectionately called. I worked for several years as an assistant federal public defender in Baltimore City. Over time, I have seen the city evolve, and I have seen it chew up and spit out many good people and some …

Liar, Liar, Jury's The Trier? The Future Of Neuroscience-Based Credibility Assessment And The Court, John B. Meixner Jr.

Scholarly Works

Neuroscience-based credibility-assessment tests have recently become increasingly mainstream, purportedly able to determine whether an individual is lying to a certain set of questions (the Control Question Test) or whether an individual recognizes information that only a liable person would recognize (the Concealed Information Test). Courts have hesitated to admit these tests as evidence for two primary reasons. First, following the general standard that credibility assessment is a matter solely for the trier of fact, courts exclude the evidence because it impinges on the province of the jury. Second, because these methods have not been rigorously tested in realistic scenarios, courts …

Toward Ethical Plea Bargaining, Erica J. Hashimoto

Scholarly Works

Defendants in criminal cases are overwhelmingly more likely to plead guilty than to go to trial. Presumably, at least a part of the reason that most of them do so is that it is in their interest to plead guilty, i.e., they will receive a more favorable outcome if they plead guilty than if they go to trial. The extent to which pleas reflect fair or rational compromises in practice, however, depends upon a variety of factors, including the amount of information each of the parties has about the case. Some level of informational symmetry therefore is critical to the …

Evidentiary Wisdom And Blinders In Perspective: Thoughts On Misjudging, Elaine W. Shoben

Scholarly Works

Empirical studies serve to enlighten the law, even when they simply confirm the wisdom of existing rules. Chris Guthrie's article, Misjudging, primarily serves that useful function—confirming the wisdom of existing rules—even though the author sought to establish something different. Guthrie's article applies insights from cognitive psychology to the resolution of legal disputes and presents some empirical proof of the effect of the application. He concludes that three sets of “blinders”—informational, cognitive, and attitudinal—affect the ability of judges to reach correct resolutions of disputes. He therefore recommends further appreciation of the ability of arbitration and mediation to avoid some of the …

Poetic (In)Justice? Rap Music Lyrics As Art, Life, And Criminal Evidence, Andrea L. Dennis

Scholarly Works

Courts routinely admit defendant-authored rap music lyrics as substantive evidence in the adjudication of criminal cases. In doing so, courts fail to recognize that rap music lyrics are art. Rather, judges view the interpretation of rap music lyrics as a subject of common knowledge, interpret the defendant's lyrics literally, and characterize lyrics as autobiographical depictions of actual events. In making admissibility decisions, courts must give consideration to the social constraints and artistic conventions impacting the composition and interpretation of rap music lyrics. More particularly, they must understand the commercialized nature of the rap music industry, artist claims of authenticity, and …

Daubert & Danger: The "Fit" Of Expert Predictions In Civil Commitments, Alex Scherr

Scholarly Works

The opinions of experts in prediction in civil commitment hearings should help the courts, but over thirty years of commentary, judicial opinion, and scientific review argue that predictions of danger lack scientific rigor. The United States Supreme Court has commented regularly on the uncertainty of predictive science. The American Psychiatric Association has argued to the Court that "[t]he professional literature uniformly establishes that such predictions are fundamentally of very low reliability." Scientific studies indicate that some predictions do little better than chance or lay speculation, and even the best predictions leave substantial room for error about individual cases. The sharpest …

The Supreme Court's Decision To Recognize A Psychotherapist Privilege In Jaffee V. Redmond, 116 S. Ct. 1923 (1996): The Meaning Of The Term 'Experience' And The Role Of 'Reason' Under Federal Rule Of Evidence 501, Diane Marie Amann, Edward J. Imwinkelried

Scholarly Works

In Jaffee v. United States, 116 S. Ct. 1923 (1996), the U.S. Supreme Court recognized a testimonial privilege protecting the patient-psychotherapist relationship. Its decision is based on Rule 501 of the Federal Rules of Evidence, which permits courts to decide novel questions of privilege in the light of reason and experience. The Court held that this rule authorized not only recognition of a new privilege, but also a privilege of a broad scope, extending to relationships between patients and licensed clinical social workers. Its decision came as a mild surprise, given a widely shared assumption that Rule 501 creates a …

The Proper Role Of After-Acquired Evidence In Employment Discrimination Litigation, Rebecca White, Robert D. Brussack

Scholarly Works

A new defense to employment discrimination claims has gained acceptance in the lower courts. Employers who allegedly have discriminated against their employees because of race, sex or age are winning judgments on the basis of after-acquired evidence of employee misconduct. The evidence is “after-acquired” in the sense that the misconduct was unknown to the employer at the time the alleged discrimination occurred but was acquired later, often through the use of discovery devices in the employee's discrimination action. Lower courts have accepted the proposition that if the employer would have discharged the plaintiff on the basis of the after-acquired evidence, …

The Common Law Theory Of Experts: Deference Or Education?, Joseph S. Miller, Ronald J. Allen

Scholarly Works

What if witness testimony emerges from, or can only be understood by reference to, an experience that the fact finder lacks? Or what if the connection between what a witness says and the full import of what the witness means is so arcane that the chances are virtually zero that the jury will understand what the spoken words are intended to convey? Both cases arise surprisingly frequently in the trial of disputes. For example, the problem arises whenever a witness is not fluent in English, as it often does when the common practice of a business or trade plays a …

Experts As Hearsay Conduits: Confrontation Abuses In Opinion Testimony, Ronald L. Carlson

Scholarly Works

The dispute over whether litigants may use experts to run unexamined hearsay into the trial record is a microcosm of a larger debate. The larger question is whether judicial review of expert testimony should be passive, or whether the expert witness process should be marked by active judicial policing. Does the plethora of expert opinions presently being offered in modern trials merit special scrutiny by the courts?

Some scholars urge that courts must accommodate experts. Proponents of this view favor few challenges to the unrestricted rendition of opinions by an expert, whether the expert is real or self-proclaimed. Under this …

Policing The Bases Of Modern Expert Testimony, Ronald L. Carlson

Scholarly Works

The expanding array of scientific (as well as some not-so-scientific) specialties available as sources for testimony raises hard questions. Will courts require that the witness' opinions be reasonably based upon trustworthy data? How far must judges inquire into the practice of other experts in the same field prior to allowing the trial witness to proffer an expert opinion? How much of the expert's supporting data will be received in evidence? This Essay addresses these and other important questions affecting the scope of modern expert testimony.

Part I will argue that certainty is especially important in the law of negotiable instruments, although it does not outweigh all other values. In light of the need for certain rules, this Article will consider the policy choices made by the drafters of the Uniform Commercial Code's Article 3 on Commercial Paper with respect to parol evidence. Part II will examine certain parol evidence that is admissible against even the law's most favored plaintiff, the holder in due course. Part III will focus on the Code's indirect treatment of the most troublesome parol evidence problems, those which arise when the …
