The Science Of Gatekeeping: Using The Structure Of Scientific Inference To Draw The Line Between Admissibility And Weight In Expert Testimony, Christopher Slobogin, David Faigman, John Monahan

Vanderbilt Law School Faculty Publications

Fundamental to all evidence rules is the division of responsibility between the judge, who determines the admissibility of evidence, and the jury, which gauges its weight. In most evidentiary contexts, such as those involving hearsay and character, threshold admissibility obligations are clear and relatively uncontroversial. The same is not true for scientific evidence. The complex nature of scientific inference, and in particular the challenges of reasoning from group data to individual cases, has bedeviled courts. As a result, courts vary considerably on how they define the judge's gatekeeping task under Federal Rule of Evidence 702 and its state equivalents.

Cardozo Journal of Equal Rights & Social Justice

This symposium examines the legal and social challenges faced by transgender individuals, particularly in the context of bathroom access and anti-trans legislation. It emphasizes the importance of a holistic approach to trans liberation, combining legal advocacy, grassroots efforts, and education. The analysis highlights the multifaceted nature of trans rights, including the role of storytelling, intersectionality, and the impact of political shifts on LGBT protections. The symposium underscores the need for a comprehensive strategy to achieve equality and justice for trans communities.

Prior Consistent Statements: The Dangers Of Misinterpreting Recently Amended Federal Rule Of Evidence 801(D)(1)(B), Laird C. Kirkpatrick, Christopher B. Mueller

Publications

A recent amendment to Federal Rule of Evidence 801(d)(1)(B) expands the situations in which prior consistent statements by testifying witnesses can be used as substantive evidence, and not merely as rehabilitating evidence. In this piece, the Authors argue that the revised rule may mislead judges and lawyers to conclude that prior consistent statements are always usable as substantive evidence when offered to rehabilitate a witness. Nothing could be further from the truth. The intent, although hard to discern on the face of the revised rule, is only to allow substantive use of consistent statements that are otherwise admissible to rehabilitate …

Bringing Demonstrative Evidence In From The Cold: The Academy's Role In Developing Model Rules, Maureen A. Howard, Jeffry C. Barnum

Articles

To this day, judges and advocates struggle with the definition and use of "demonstrative evidence." The ambiguity of this term (or its close cousins "illustrative evidence" and evidence offered "for illustrative purposes only") infects the judicial process with uncertainty, hindering advocates when preparing for trial and, in some cases, producing erroneous verdicts. For example, the Seventh Circuit recently reversed a case for improper use of a demonstrative exhibit, and on retrial the result swung from a defense verdict to an $11 million plaintiffs victory. Uncertainty about the admission and use of demonstrative evidence has festered for decades. Lawyers innovate in …

Privacy, Public Disclosure, Police Body Cameras: Policy Splits, Mary D. Fan

Articles

When you call the police for help—or someone calls the police on you—do you bear the risk that your worst moments will be posted on YouTube for public viewing? Police officers enter some of the most intimate incidences of our lives—after an assault, when we are drunk and disorderly, when someone we love dies in an accident, when we are distraught, enraged, fighting, and more. As police officers around the nation begin wearing body cameras in response to calls for greater transparency, communities are wrestling with how to balance privacy with public disclosure.

This Article sheds light on the balances …

Law And Politics, An Emerging Epidemic: A Call For Evidence-Based Public Health Law, Michael Ulrich

Faculty Scholarship

As Jacobson v. Massachusetts recognized in 1905, the basis of public health law, and its ability to limit constitutional rights, is the use of scientific data and empirical evidence. Far too often, this important fact is lost. Fear, misinformation, and politics frequently take center stage and drive the implementation of public health law. In the recent Ebola scare, political leaders passed unnecessary and unconstitutional quarantine measures that defied scientific understanding of the disease and caused many to have their rights needlessly constrained. Looking at HIV criminalization and exemptions to childhood vaccine requirements, it becomes clear that the blame cannot be …

Is There Really A Sex Bureaucracy?, Suzanne B. Goldberg

Faculty Scholarship

This essay identifies several features of the higher-education context that can enrich The Sex Bureaucracy‘s account of why colleges and universities have adopted new policies and trainings to address sexual assault on their campuses. These features include: 1) schools’ preexisting systems for addressing student conduct; 2) the shared interest of schools in reducing impediments to education, including nonconsensual sexual contact; and 3) the pedagogical challenges of developing trainings that are engaging and effective. Taking these three factors into account, we can see that while federal Title IX intervention has had a profound effect, it is also important not to …

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 …

Criminal Adjudication, Error Correction, And Hindsight Blind Spots, Lisa Kern Griffin

Faculty Scholarship

Concerns about hindsight in the law typically arise with regard to the bias that outcome knowledge can produce. But a more difficult problem than the clear view that hindsight appears to provide is the blind spot that it actually has. Because of the conventional wisdom about error review, there is a missed opportunity to ensure meaningful scrutiny. Beyond the confirmation biases that make convictions seem inevitable lies the question whether courts can see what they are meant to assess when they do look closely for error. Standards that require a retrospective showing of materiality, prejudice, or harm turn on what …

Dna And Distrust, Kerry Abrams, Brandon L. Garrett

Faculty Scholarship

Over the past three decades, government regulation and funding of DNA testing has reshaped the use of genetic evidence across various fields, including criminal law, family law, and employment law. Courts have struggled with questions of when and whether to treat genetic evidence as implicating individual rights, policy trade-offs, or federalism problems. We identify two modes of genetic testing: identification testing, used to establish a person’s identity, and predictive testing, which seeks to predict outcomes for a person. Judges and lawmakers have often drawn a bright line at predictive testing, while allowing uninhibited identity testing. The U.S. Supreme Court in …

Two Models Of Pre-Plea Discovery In Criminal Cases: An Empirical Comparison, Jenia I. Turner, Allison D. Redlich

Faculty Journal Articles and Book Chapters

Our criminal justice system resolves most of its cases through plea bargains. Yet the U.S. Supreme Court has not required that any evidence, even exculpatory or impeachment evidence, be provided to the defense before a guilty plea. As a result, state rules on pre-plea discovery differ widely. While some jurisdictions follow an “open-file” model, imposing relatively broad discovery obligations on prosecutors early in the criminal process, others follow a more restrictive, “closed-file” model and allow the prosecution to avoid production of critical evidence either entirely or until very near the time of trial. Though the advantages and disadvantages of both …

Confrontation As A Rule Of Production, Pamela R. Metzger

Faculty Journal Articles and Book Chapters

The Confrontation Clause is cost blind; the Supreme Court is not. In 2004, in Crawford v. Washington, the Supreme Court trumpeted its commitment to a procedural Confrontation Clause that required the prosecution to produce its witnesses in court, regardless of the cost or inconvenience. In 2007, in Melendez-Diaz v. Massachusetts, the Court retreated, offering courts, legislatures, and prosecutors an easy way to avoid Confrontation-laden trials. On the one hand, the Court warned that legislatures and courts could not “suspend the Confrontation Clause,” even if there were “other ways — and in some cases better ways — to challenge or verify” …

Barber V. State, 131 Nev. Adv, Op. 103 (December 31, 2015), Ronni N. Boscovich

Nevada Supreme Court Summaries

The Court considered an appeal from a district court conviction. The Court reversed the Eighth Judicial District Court’s judgment of conviction, pursuant to a jury verdict of burglary and grand larceny. The juvenile court retains jurisdiction over Barber because the legislation did not include language regarding jurisdiction stripping or dismissal requirements. However, the Court reversed the judgment because the prosecution presented insufficient evidence to support Barber’s conviction.

Moultrie V. State, 131 Nev. Adv. Op. 93 (Dec. 24, 2015), Cassandra Ramey

Nevada Supreme Court Summaries

The Court of Appeals determined that the district court did not abuse its discretion by allowing the State to file an information by affidavit more than 15 days after the preliminary examination concluded, when the justice court committed an “egregious error,” and “the defendant was discharged but not prejudiced by the delay.” Further, the Court defines “egregious error” as when “a charge was erroneously dismissed or a defendant was erroneously discharged based on a magistrate’s error.” Due to the justice court’s egregious errors in the preliminary examination that resulted in appellant’s discharge, the Court found that the district court was …

Berry V. State, 131 Nev. Adv. Op. No. 96 (Dec. 24, 2015), Brittany L. Shipp

Nevada Supreme Court Summaries

The issue before the Court was an appeal from a district court order dismissing a post-conviction petition for writ of habeas corpus. The Court reversed and remanded holding that the district court improperly discounted the declarations in support of the appellant’s petition, which included a confession of another suspect, whom the petitioner implicated as the real perpetrator at trial. The Court held that these declarations were sufficient to merit discovery, and an evidentiary hearing on Petitioner Berry’s gateway actual innocence claim.

Flaws In The Justice System: Examining The Angel Cordero Case, Rose C. Itzcovitz

Capstones

This article examines a case in criminal law that started 17 years ago and has yet to be resolved. Despite a plethora of mounting evidence, including a confession, more than a dozen witnesses, a proven false alibi, impeaching evidence against police and DNA evidence, Bronx-born Angel Cordero's conviction has yet to be overturned. The article breaks down what went wrong in the initial trial, discusses Cordero's multiple appeals and takes a broader look at what needs to change in today's judicial system.

Schools Fail To Get It Right On Rap Music, Andrea L. Dennis

Popular Media

School officials treat rap music as a serious threat to the school environment. Fear and misunderstanding of, as well as bias against, this highly popular and lucrative musical art form negatively shape their perspectives on this vital aspect of youth culture.

As a result, students who express themselves through rap music in a way that challenges the schoolhouse setting risk the possibility of suspension, permanent exclusion and referral to the criminal justice system.

The ongoing case of Taylor Bell is the latest and most complex battleground on which this issue is playing out.

Neuro Lie Detection And Mental Privacy, Madison Kilbride, Jason Iuliano

Maryland Law Review

New technologies inevitably raise novel legal questions. This is particularly true of technologies, such as neuro lie detection, that offer new ways to investigate crime. Recently, a number of scholars have asked whether neuro lie detection testing is constitutional. So far, the debate has focused on the Fifth Amendment—specifically whether evidence gathered through neuro lie detection is constitutionally admissible because it is “physical” in nature or inadmissible because it is “testimonial” in nature. Under current Supreme Court doctrine, this Fifth Amendment debate is intractable. However, the more fundamental question of whether the government can compel individuals to undergo a neuro …

The Ethical Limits Of Discrediting The Truthful Witness: How Modern Ethics Rules Fail To Prevent Truthful Witnesses From Being Discredited Through Unethical Means, Todd A. Berger

Marquette Law Review

Whether the criminal defense attorney may ethically discredit the truthful witness on cross-examination and later during closing argument has long been an area of controversy in legal ethics. The vast majority of scholarly discussion on this important ethical dilemma has examined it in the abstract, focusing on the defense attorney’s dual roles in a criminal justice system that is dedicated to searching for the truth while simultaneously requiring zealous advocacy even for the guiltiest of defendants. Unlike these previous works, this particular Article explores this dilemma from the perspective of the techniques that criminal defense attorney’s use on cross-examination and …

The Novel New Jersey Eyewitness Instruction Induces Skepticism But Not Sensitivity, Athan Papailiou, David Yokum, Christopher Robertson

Faculty Scholarship

In recent decades, social scientists have shown that the reliability of eyewitness identifications is much worse than laypersons tend to believe. Although courts have only recently begun to react to this evidence, the New Jersey judiciary has reformed its jury instructions to notify jurors about the frailties of human memory, the potential for lineup administrators to nudge witnesses towards suspects that they police have already identified, and the advantages of alternative lineup procedures, including blinding of the administrator. This experiment tested the efficacy of New Jersey’s jury instruction. In a 2×2 between-subjects design, mock jurors (N = 335) watched a …

Authenticity And Admissibility Of Social Media Website Printouts, Wendy Angus-Anderson

Duke Law & Technology Review

Social media posts and photographs are increasingly denied admission as evidence in criminal trials. Courts often cite issues with authentication when refusing to admit social media evidence. Cases and academic writings separate recent case law into two approaches: The Maryland Approach and the Texas Approach. The first method is often seen as overly skeptical of social media evidence, setting the bar too high for admissibility. The second approach is viewed as more lenient, declaring that any reasonable evidence should be admitted in order for a jury to weigh its sufficiency. This Brief addresses the supposed differences between the two sets …
