Neuropsychological Malingering Determination: The Illusion Of Scientific Lie Detection, Chunlin Leonhard, Christoph Leonhard

Georgia Law Review

Humans believe that other humans lie, especially when stakes are high. Stakes can be very high in a courtroom, from substantial amounts of monetary damages in civil litigation to liberty or life in criminal cases. One of the most frequently disputed issues in U.S. courts is whether litigants are malingering when they allege physical or mental conditions for which they are seeking damages or which would allow them to avoid criminal punishment. Understandably, creating a scientific method to detect lies is very appealing to all persons engaged in lie detection. Neuropsychologists claim that they can use neuropsychological assessment tests (Malingering …

The New People V. Collins: How Can Probabilistic Evidence Be Properly Admitted?, David Crump

Maine Law Review

The California Supreme Court’s decision in People v. Collins is a staple in Evidence casebooks. An innovative assistant district attorney in the trial court had presented a mathematician who applied probabilities to questions about the perpetrators’ characteristics. The state supreme court disapproved the injection of an equation featuring what mathematicians call the “product rule.” The opinion contains thank-goodness-we-escaped-that-disaster reasoning and condemnation of this use of mathematics with probabilities. But the court’s analysis probably would be different if the case were decided today, as the “new” People v. Collins. Therefore, this Article considers what the author calls the new People v. …

Bending The Rules Of Evidence, Edward K. Cheng, G. Alexander Nunn, Julia Simon-Kerr

Northwestern University Law Review

The evidence rules have well-established, standard textual meanings—meanings that evidence professors teach their law students every year. Yet, despite the rules’ clarity, courts misapply them across a wide array of cases: Judges allow past acts to bypass the propensity prohibition, squeeze hearsay into facially inapplicable exceptions, and poke holes in supposedly ironclad privileges. And that’s just the beginning.

The evidence literature sees these misapplications as mistakes by inept trial judges. This Article takes a very different view. These “mistakes” are often not mistakes at all, but rather instances in which courts are intentionally bending the rules of evidence. Codified evidentiary …

The History Of Forensic-Science Evidence In Criminal Trials And The Role Of Early “Success” In Establishing Its Putative Reliability, Carrie Leonetti

St. Mary's Law Journal

This Article posits the history of forensic-science evidence plays a significant role in the unquestioning manner of its modern acceptance. It traces early high-profile forensic science “successes” and the public reactions to them. It argues the public perception of the “advances” of forensic science continues to play a role in the lack of scrutiny given to these disciplines in admissibility decisions today. It concludes, when it comes to forensic science, history should play a different role by serving as a critical warning rather than a congratulatory buttress.

The Case For The Abolition Of Criminal Confessions, Guha Krishnamurthi

SMU Law Review

Confessions have long been considered the gold standard of evidence in criminal proceedings. But in truth, confession evidence imposes significant harms on our criminal justice system, through false convictions and other violations of defendants’ due process and moral rights. Moreover, our current doctrine is unable to eliminate or even curb these harms.

This Article makes the case for the abolition of confession evidence in criminal proceedings. Though it may seem radical, abolition is sensible and best furthers our penological goals. As a theoretical matter, confession evidence has low probative value, but it is prejudicially overvalued by juries and judges. Consequently, …

Artificial Intelligence As Evidence, Paul W. Grimm, Maura R. Grossman, Gordon V. Cormack

Northwestern Journal of Technology and Intellectual Property

This article explores issues that govern the admissibility of Artificial Intelligence (“AI”) applications in civil and criminal cases, from the perspective of a federal trial judge and two computer scientists, one of whom also is an experienced attorney. It provides a detailed yet intelligible discussion of what AI is and how it works, a history of its development, and a description of the wide variety of functions that it is designed to accomplish, stressing that AI applications are ubiquitous, both in the private and public sectors. Applications today include: health care, education, employment-related decision-making, finance, law enforcement, and the legal …

Willful Blindness As Mere Evidence, Gregory M. Gilchrist

Loyola of Los Angeles Law Review

The willful blindness doctrine at criminal law is well-established and generally fits with moral intuitions of guilt. It also stands in direct tension with the first principle of American criminal law: legality. This Article argues that courts could largely preserve the doctrine and entirely avoid the legality problem with a simple shift: willful blindness ought to be reconceptualized as a form of evidence.

Rock And Hard Place Arguments, Jareb Gleckel, Grace Brosofsky

Seattle University Law Review

This Article explores what we coin “rock and hard place” (RHP) arguments in the law, and it aims to motivate mission-driven plaintiffs to seek out such arguments in their cases. The RHP argument structure helps plaintiffs win cases even when the court views that outcome as unfavorable.

We begin by dissecting RHP dilemmas that have long existed in the American legal system. As Part I reveals, prosecutors and law enforcement officials have often taken advantage of RHP dilemmas and used them as a tool to persuade criminal defendants to forfeit their constitutional rights, confess, or give up the chance to …

Assertion And Hearsay, Richard Lloret

Dickinson Law Review (2017-Present)

This article explores the characteristics and functions of assertion and considers how the term influences the definition of hearsay under Federal Rule of Evidence 801. Rule 801(a) defines hearsay by limiting it to words and conduct intended as an assertion, but the rule does not define the term assertion. Courts and legal scholars have focused relatively little attention on the nature and definition of assertion. That is unfortunate, because assertion is a robust concept that has been the subject of intense philosophic study over recent decades. Assertion is not a mere cypher standing in for whatever speech or conduct one …

Unbuckling The Seat Belt Defense In Arkansas, Spencer G. Dougherty

Arkansas Law Review

The “seat belt defense” has been hotly litigated over the decades in numerous jurisdictions across the United States. It is an affirmative defense that, when allowed, reduces a plaintiff’s recovery for personal injuries resulting from an automobile collision where the defendant can establish that those injuries would have been less severe or avoided entirely had the plaintiff been wearing an available seat belt. This is an unsettled legal issue in Arkansas, despite the growing number of cases in which the seat belt defense is raised as an issue. Most jurisdictions, including Arkansas, initially rejected the defense, but the basis for …

Lie To Me: Examining Specific Intent Under 18 U.S.C. §§ 1001, 1035

Florida A & M University Law Review

One court notes that the Supreme Court of the United States (“SCOTUS”) has previously not found specific intent to be required under similar language within Section 1001.9 While there are many similarities between Sections 1001 and 1035, there are salient differences. Notwithstanding the differences, this Article argues that Sections 1001 and 1035 should be interpreted without “intent to deceive” and rather be interpreted as a strict liability offense. This argument began with Part I, which provided a brief introduction regarding specific intent under Sections 1001 and 1035. Part II examines the purpose of criminalizing false statements, which identifies why the …

Why Do We Admit Criminal Confessions Into Evidence?, David Crump

Seattle University Law Review

There is an enormous literature about the admissibility of criminal confessions. But almost all of it deals with issues related to self-incrimination or, to a lesser extent, with hearsay or accuracy concerns. As a result, the question whether we ever admit criminal confessions into evidence has not been the subject of much analysis. This gap is odd, since confessions are implicitly disfavored by a proportion of the literature and they often collide with exclusionary doctrines. Furthermore, the self-incrimination issue sometimes is resolved by balancing, and it would help if we knew what we were balancing. Therefore, one might ask: Why …

Justice Begins Before Trial: How To Nudge Inaccurate Pretrial Rulings Using Behavioral Law And Economic Theory And Uniform Commercial Laws, Michael Gentithes

William & Mary Law Review

Injustice in criminal cases often takes root before trial begins. Overworked criminal judges must resolve difficult pretrial evidentiary issues that determine the charges the State will take to trial and the range of sentences the defendant will face. Wrong decisions on these issues often lead to wrongful convictions. As behavioral law and economic theory suggests, judges who are cognitively busy and receive little feedback on these topics from appellate courts rely upon intuition, rather than deliberative reasoning, to resolve these questions. This leads to inconsistent rulings, which prosecutors exploit to expand the scope of evidentiary exceptions that almost always disfavor …

Between Brady Discretion And Brady Misconduct, Bennett L. Gershman

Dickinson Law Review (2017-Present)

The Supreme Court’s decision in Brady v. Maryland presented prosecutors with new professional challenges. In Brady, the Supreme Court held that the prosecution must provide the defense with any evidence in its possession that could be exculpatory. If the prosecution fails to timely turn over evidence that materially undermines the defendant’s guilt, a reviewing court must grant the defendant a new trial. While determining whether evidence materially undermines a defendant’s guilt may seem like a simple assessment, the real-life application of such a determination can be complicated. The prosecution’s disclosure determination can be complicated under the Brady paradigm because …

Where The Constitution Falls Short: Confession Admissibility And Police Regulation, Courtney E. Lewis

Dickinson Law Review (2017-Present)

A confession presented at trial is one of the most damning pieces of evidence against a criminal defendant, which means that the rules governing its admissibility are critical. At the outset of confession admissibility in the United States, the judiciary focused on a confession’s truthfulness. Culminating in the landmark case Miranda v. Arizona, judicial concern with the reliability of confessions shifted away from whether a confession was true and towards curtailing unconstitutional police misconduct. Post-hoc constitutionality review, however, is arguably inappropriate. Such review is inappropriate largely because the reviewing court must find that the confession was voluntary only by …

Termination Of Hospital Medical Staff Privileges For Economic Reasons: An Appeal For Consistency, June D. Zellers, Michael R. Poulin

Maine Law Review

The relationship between physicians and hospitals is undergoing significant change. Historically, a physician maintained a private practice in the community and looked to the local hospital for ancillary support when his or her patients were too ill to remain at home. This community-based physician gained access to the hospital by obtaining medical staff privileges. These privileges allowed the physician to admit patients to the hospital, treat patients while they were there, and use the hospital's staff and equipment. The physician generally enjoyed the use of the privileges throughout his or her active career, losing them only if found incompetent. Today, …

Life After Daubert V. Merrell Dow: Maine As A Case Law Laboratory For Evidence Rule 702 Without Frye, Leigh Stephens Mccarthy

Maine Law Review

In reaching its recent decision in Daubert v. Merrell Dow Pharmaceuticals, Inc., the United States Supreme Court grappled not with case law but with fundamental questions about the nature of science and its role in law. The court in Daubert addressed the problematic issue of admissibility of expert scientific testimony. In the end the Court rejected as an exclusionary rule the venerable standard set in 1923 by Frye v. United States. Frye held that scientific testimony was to be excluded unless it had gained “general acceptance” in its field. Daubert held that Rule 702 of the Federal Rules of Evidence …

Prosecutorial Summation: Where Is The Line Between "Personal Opinion" And Proper Argument?, James W. Gunson

Maine Law Review

Prosecutorial forensic misconduct has become front page news in Maine. Since April of 1993, the Maine Supreme Judicial Court, sitting as the Law Court, has reversed convictions in three highly publicized cases based on remarks made by the prosecutor. In State v. Steen, the prosecutor asked the defendant to give his opinion concerning the veracity of other witnesses and suggested in closing argument that the favorable testimony given by the defense's expert witness resulted from the fee he had received. The Law Court vacated the gross sexual assault conviction, finding that the prosecutor's questions and closing argument “clearly suggested” to …

The (Mis)Application Of Rule 404(B) Heuristics, Dora W. Klein

University of Miami Law Review

In all of the federal circuit courts of appeals, application of Rule 404(b) of the Federal Rules of Evidence has been distorted by judicially-created “tests” that, while intended to assist trial courts in properly admitting or excluding evidence, do not actually test for the kind of evidence prohibited by this rule. Rule 404(b) prohibits evidence of “crimes, wrongs, or other acts” if the purpose for admitting the evidence is to prove action in accordance with a character trait. This evidence is commonly referred to as “propensity” evidence, or “once a drug dealer, always a drug dealer” evidence.

Trammel V. United States: Bad History, Bad Policy, And Bad Law, Michael W. Mullane

Maine Law Review

In 1980 the United States Supreme Court decided Trammel v. United States. The opinion changed the Spouses' Testimonial Privilege, overturning centuries of consistent case decisions. The Court based its decision on the history and effect of privilege and a straw poll of state legislative and court decisions on the issue. The Court concluded its decision would permit the admission of more spousal testimony without impairing the benefits the privilege was supposed to confer on spouses. The Court's decision in Trammel was wrong on three counts. The first was bad history overlaid with questionable analysis. The survey of the state's treatment …

Identifying And Preventing Improper Prosecutorial Comment In Closing Argument, Robert W. Clifford

Maine Law Review

In recent years, several decisions of the Maine Supreme Judicial Court sitting as the Law Court have addressed the comments of prosecutors in final argument before criminal juries. Three of those decisions in particular have caused concern among prosecutors and have stirred discussion in the Maine legal community. In vacating convictions in State v. Steen, State v. Casella, and State v. Tripp, the Law Court focused on the language used by the prosecutors during closing argument and concluded that those prosecutors impermissibly expressed personal opinion concerning the credibility of the defendants, or witnesses called by the defendants. This Article examines …

Innovating Criminal Justice, Natalie Ram

Northwestern University Law Review

From secret stingray devices that can pinpoint a suspect’s location, to advanced forensic DNA-analysis tools, to recidivism risk statistic software—the use of privately developed criminal justice technologies is growing. So too is a concomitant pattern of trade secret assertion surrounding these technologies. This Article charts the role of private law secrecy in shielding criminal justice activities, demonstrating that such secrecy is pervasive, problematic, and ultimately unnecessary for the production of well-designed criminal justice tools.

This Article makes three contributions to the existing literature. First, the Article establishes that trade secrecy now permeates American criminal justice, shielding privately developed criminal justice …

Calling Crawford: Minnesota Declares A 911 Call Non-Testimonial In State V. Wright, Alistair Y. Raymond

Maine Law Review

In State v. Wright, 1 the State of Minnesota charged David Wright with possession of a firearm by a felon and two counts of second-degree assault against his girlfriend and her sister. A jury found Wright guilty on all charges and sentenced him to sixty months in jail for each crime, with sentences served concurrently. Wright’s girlfriend, R.R., and her sister, S.R., did not testify against him at trial. The prosecution, however, used the transcript of a 911 call placed by R.R. against Wright in the trial. Although the 911 call was hearsay, the court admitted it under Minnesota’s excited …

State V. Thurston: An Examination Of Assualt, Self-Defense, And Trespass In Relation To Domestic Violence, Megan E. Magoon

Maine Law Review

Darrell Thurston and Suzanne Harmon were romantically involved on an intermittent basis for five years and had one child together. As a result of an altercation that took place at Harmon’s home in Sullivan, Maine, on September 27, 2007, between Thurston and Harmon, Thurston was charged with assault, criminal mischief, and obstructing report of crime or injury. The testimony during the trial illuminated the major factual differences between Thurston’s and Harmon’s accounts of the night the incident took place. Thurston requested a self defense jury instruction based on his version of what had happened, which the trial court ultimately denied. …

Mass Suppression: Aggregation And The Fourth Amendment, Nirej Sekhon

Georgia Law Review

The FourthAmendment's exclusionary rule requires that
criminal courts suppress evidence obtained as a result of
an unconstitutionalsearch or seizure. The Supreme Court
has repeatedly stated that suppression is purely
regulatory, not remedial. Its only purpose is to deter
future police misconduct, not to remedy past privacy or
liberty harms suffered by the defendant. Exclusion, in
other words, is for the benefit of community members who
might, sometime in the future, be subject to police
misconduct like that endured by the defendant.
Exclusion's regulatory purpose would be greatly aided if
criminal courts could identify when a suppression motion
involved Fourth Amendment …
