Evidence, W. Randall Bassett

Mercer Law Review

In its 2023 term, the United States Court of Appeals for the Eleventh Circuit focused heavily on the role and admissibility of expert testimony under Rules 702–704 of the Federal Rules of Evidence. For example, in two opinions, the court considered the role of an expert’s qualifications and experience in supporting the admissibility of the expert’s opinions. In another case, they analyzed the scope of an expert’s ability to opine on an ultimate issue in a criminal case. The court also considered the role of lay witness opinion testimony compared to that of a retained expert and the admissibility of …

I’Ll Huff, And I’Ll Puff, And I’Ll Blow Your Parol Evidence Down: The Eleventh Circuit Explains Why The Plain Text Of An Insurance Policy Wins In The Face Of Contractual Ambiguity, Chloe E. Bonds

Mercer Law Review

Imagine that a small business in sunny, central Florida is evaluating its insurance policy. The business notices that the policy includes seemingly unnecessary coverage for losses caused by landslides. Before the end of the current year, the business contacts its insurance agency and successfully negotiates to remove the existing landslide coverage from next year’s policy. Following the negotiations, the agent issues an updated insurance binder reflecting the change. Although the insurance agency is aware that the business no longer wants landslide coverage, the principal policy issued after negotiations conspicuously does not include any language regarding the coverage or exclusion of …

Cyanoacrylate Deposition Onto Sebum With Pretreatment Of Amine, Isaac Baltz

Chemistry & Biochemistry Undergraduate Honors Theses

Super glue, or ethyl cyanoacrylate, fuming is commonly used in forensic science to develop latent fingerprints on nonporous surfaces[7]. Fingerprints are primarily made up of the oily substance secreted by sebaceous glands better known as sebum. Previously it has been shown that exposure of fingerprints to diisopropylamine dramatically increases the deposition of cyanoacrylate polymers on the fingerprints[1]. However, the heterogeneity of any series of real fingerprints made it difficult to quantitatively assess this effect. This heterogeneity includes not just the amount of sebum but the presence of unknown amounts of proteins, amino acids, and other potential nucleophiles which catalyze the …

Symposium On Scholars’ Suggestions For Amendments, And Issues Raised By Artificial Intelligence

Fordham Law Review

CHAIR SCHILTZ: As those of you who have been in the rules work for a while know, rules work is cyclical. During the time I’ve been Chair of the Advisory Committee on Evidence Rules, we’ve had two packages of amendments that have gone through. The first package will take effect on December 1, 2024, and that’s the package that is led by the amendment to Rule 702 on expert testimony. And then we have another package that was just approved by the Judicial Conference and sent to the U.S. Supreme Court, and that package is led by the new rule …

Impeaching With An Alleged Prior False Accusation, Erin Murphy

Fordham Law Review

The Court’s categorical recognition of bias as a constitutionally protected, and therefore rape-shield recognized, exception to the general bar on evidence of sexual history has led to questions about whether other forms of impeachment might also evade rape shield restrictions. In particular, courts have grappled with the admissibility of impeachment by evidence of a prior false accusation (PFA).

The current treatment of PFAs is inconsistent and controversial for several reasons. First, as explained further in Part I, there is a lack of clear guidance in the rules about how such evidence should be treated. Second, of course, there are the …

Judges Should Be Discerning Consensus, Not Evaluating Scientific Expertise, David S. Caudill, Harry Collins, Robert Evans

Faculty Publications

One of the most constructive critiques of the Daubert admissibility regime is Professor Edward Cheng’s recent proposal for a new Consensus Rule in the Federal Rules of Evidence. Rejecting the notion that judges and juries have the capacity to evaluate scientific expertise, Cheng’s proposal would eliminate Daubert hearings—and judicial gatekeeping concerning expert testimony—and require judges and juries, in their verdicts, to follow consensus in the relevant scientific community. Significantly, Cheng argues that judges and juries would have an easier time identifying consensus than they have in deciding between experts who disagree.

We find Cheng’s emphasis on consensus compelling, and …

Prosecutorial Storytelling Through Intrinsic Evidence, Brian Chen

Pepperdine Law Review

Crimes make for compelling stories. So juries make for an eager audience. Jurors want to—indeed, expect to—learn what the defendant did, how they did it, and why they deserve punishment. Capable prosecutors know how to deliver. Trial narratives empower jurors to link discrete pieces of evidence and infer facts from circumstantial proof. Only then can they render a verdict consistent with their sense of justice. Federal courts thus afford wide leeway for prosecutors to present their case as they please, with the evidence at their disposal. The Federal Rules of Evidence delineates the scope of that discretion. Under Rule 404(b), …

Machines Like Me: A Proposal On The Admissibility Of Artificially Intelligent Expert Testimony, Andrew W. Jurs, Scott Devito

Pepperdine Law Review

With the rapidly expanding sophistication of artificial intelligence systems, their reliability, and cost-effectiveness for solving problems, the current trend of admitting testimony based on artificially intelligent (AI) systems is only likely to grow. In that context, it is imperative for us to ask what rules of evidence judges today should use relating to such evidence. To answer that question, we provide an in-depth review of expert systems, machine learning systems, and neural networks. Based on that analysis, we contend that evidence from only certain types of AI systems meet the requirements for admissibility, while other systems do not. The break …

"Hired Guns": Establishing The Scope Of The Proper Cross-Examination And Argument Relating To Expert Witness' Compensation In Criminal Trials, Michael C. Kovac

Georgia Criminal Law Review

The outcomes of criminal cases can turn on the credibility of the parties’ expert witnesses. The compensation such experts receive in exchange for their work on cases can undermine their credibility, as it provides the experts with a financial incentive that might bias them in favor of the parties who retain them. While concerns with such bias have existed for decades, courts have been inconsistent in the defining the permissible scope of cross-examination and argument on the issue. Some courts have unduly curtailed such cross-examination and argument. Courts have also been inconsistent in their views of whether calling such expert …

All Eyez On Rap & Hip-Hop: Analyzing How Black Expression Is Criminalized And The Language Of The Rap Act Of 2022, Maia Young

Washington Journal of Law, Technology & Arts

The Black existence, in the United States of America, has always been regarded as a conditional right. Conventionally, Blackness must always be nonviolent and non-disruptive to safely exist. Because of this, Blackness cannot be confined to restraints and disrupts these conventions with acts of joy and creative expression. Black creativity is both unconventional and sacred. Black creative expression documents, preserves, and unifies cultural lived experiences, from a first-hand lens of those oppressed. Creative and artistic expression celebrates the myriad of stories that are a part of the collective Black experience. Yet, Black creative expression is now being weaponized by prosecutors …

The Brady Database, Brandon L. Garrett, Adam M. Gershowitz, Jennifer Teitcher

Faculty Publications

The Supreme Court’s landmark ruling in Brady v. Maryland turns sixty this year. The Brady doctrine, which requires the government to disclose favorable and material evidence to the defendant, is one of the most frequently litigated criminal procedure issues. Yet, despite decades of Brady cases in federal and state courts, we still know relatively little about how Brady claims are litigated, adjudicated, and what such claims can tell us about the criminal justice system writ large. Scholars are in the dark about how often Brady violations occur, whether it is primarily the fault of prosecutors or the police, whether violations …

Unconscionability & Involuntary Arbitration Agreements: The Systemic Exploitation Of Immigrant Labor In The United States, Isabel Ortega-Romero

Cardozo Journal of Equal Rights & Social Justice

The note examines the inadequacy of the doctrine of unconscionability in protecting immigrant workers from exploitation through unfair contracts and arbitration agreements. It advocates for legal reforms, including the regulation of arbitration agreements and the recognition of unconscionability as a tort, to address these issues.

Emotionally Harmed? It Might Not Matter: An Analysis Of Cummings V. Premier Rehab Keller And Its Implications For Title Ii Of The Americans With Disabilities Act Of 1990, Sotir Zhupa

Cardozo Law Review

On April 28, 2022, the U.S. Supreme Court handed down an opinion that shocked the disability rights community. In Cummings v. Premier Rehab Keller, P.L.L.C., the Court ruled that compensatory damages for emotional distress may not be recovered by claimants who sue for disability discrimination under section 504 of the Rehabilitation Act of 1973 (section 504) and section 1557 of the Patient Protection and Affordable Care Act of 2010..

Cummings involved a woman, Jane Cummings, who is both deaf and legally blind. Because of her disabilities, she communicates through American Sign Language (ASL)—her first and primary language—and cannot communicate …

Measuring Jury Perception Of Explainable Machine Learning And Demonstrative Evidence, Rachel Edie Sparks Rogers

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Subjective pattern comparison has been subject to increased scrutiny by the courts and by the general public, resulting in an increased interest in pattern comparison algorithms that provide quantitative assessments of similarity for use by forensic scientists. While these algorithms would mark an improvement over current subjective comparison methods, individuals without a statistical background may struggle with the statistical concepts and language necessary for describing algorithmic methods. If algorithms are to be used, examiners must be able to testify about their use in a way that is accessible to the jury. In a series of studies, we conduct an assessment …

Transparency In Forensic Exams, Dorothy Sims, Chris Dove, Richard Frederick

Nevada Law Journal

Medical examination of injured plaintiffs by doctors hired by defendants is a staple of modern tort litigation. Federal Rule of Civil Procedure 35 and its state counterparts authorize such examinations when the plaintiff’s physical or mental condition is at issue. Although typically dubbed “independent” medical examinations or IMEs, their use often appears to be anything but independent in that defense-retained medical professionals have a strong financial incentive to dispute or diminish injury claims in order to obtain or retain a steady stream of lucrative work from defendants and their insurers.

Although often tainted, defense-driven medical examinations rema33330p[in necessary as a …

The Precarious Art Of Classifying Facts, Allison Orr Larsen

Faculty Publications

In their terrific new article, Fact Stripping, Joseph Blocher and Brandon Garrett bring formidable expertise from their respective fields to tackle the inscrutable puzzle of appellate fact review.

[...]

In this short reply I will add to Blocher and Garrett’s illuminating work by exploring a foundational confusion their article exposes. I will first explain why classifying facts as either suitable for trial or not is a very fraught endeavor; I will then argue that this difficulty allows for significant manipulation and the risk of unprincipled application. Finally, I will nod to prior work and forecast future work where I …

Garrity Immunity And The U.S. Armed Forces, Bretton H. Laudeman, Gabriel J. Chin

BYU Law Review

The U.S. military is one of the nation’s largest and most important public employers. Given the unique nature of military service, the service branches have a strong interest in ensuring the integrity of their ranks. Yet the military lacks a critical force-management tool used by every other public employer to investigate workplace misconduct: the ability to demand answers to potentially incriminating questions under Garrity v. New Jersey, 385 U.S. 493 (1967). The Garrity solution, known as “Garrity immunity,” strikes a critical balance between the government’s interests in workplace oversight and accountability with the employee’s Fifth Amendment right against self-incrimination by …

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 …
