Justified: Reasonable Beliefs, True Beliefs, And Self-Defense, Michael D. Cicchini

Marquette Law Review

A defendant is charged with criminal battery and asserts self-defense at trial. The defense calls witnesses who would testify that, about ten minutes before the fight, the alleged victim said he was going to “find” the defendant and “end him.” But the trial judge excludes the testimony because the threat, while heard by several witnesses, was not communicated to the defendant. Therefore, the judge says, the threat cannot be relevant in determining whether the defendant “reasonably believed” he was in imminent danger at that time.

This Article explores the theoretical foundation for this common ruling and demonstrates why it is …

The Federal Rules Of Evi-Dance: Exploring And Reimagining Evidence Law Through Music, And Proposing Amendments To Rule 604, Brian C. Potts

Faculty Articles

Every trial has a rhythm and a flow. Every trial is a performance. This article extends the literature on law and music further into the field of evidence. I offer a new exploration and reimagining of the Federal Rules of Evidence through leitmotivs. I contend that leitmotivs—musical calling cards—reify principles of evidence law. As I spin these leitmotivs, I propose two amendments to Rule 604 regarding the oath for courtroom interpreters. I propound a new critique explaining how and why courts are wrong when they often claim “Daubert did not work a ‘seachange’ over federal evidence law.” I tender two …

Eroding Protections: The Decline Of Miranda Rights And Its Impact On Due Process In Contemporary America, Autumn G. Pelfrey

Honors Undergraduate Theses

This thesis examines whether the protections established in Miranda v. Arizona, 384 U.S. 436 (1966), remain robust within contemporary criminal justice practice or have been weakened through doctrinal and practical developments. Miranda warnings were originally designed to mitigate the risk that coercive custodial interrogation would produce compelled or unreliable self-incrimination. Since 1966, however, both judicial interpretation and evolving law-enforcement practices have created a growing gap between Miranda’s formal legal promise and its practical operation in real-world interrogations.

The study evaluates the erosion of Miranda’s protective force through three primary mechanisms. First, doctrinal developments have narrowed Miranda’s scope by redefining …

The Devil Is In The Det[Ai]Ls: Ai Agents, Ghost Students, And The Crisis Of Verified Presence In An Agentic Ai World, Aras Bozkurt, Helen Crompton, Caroline Fell Kurban

STEMPS Faculty Publications

The transition from reactive Generative Artificial Intelligence (GenAI) to agentic AI systems marks a categorical shift in digital education, moving beyond simple content generation to goal-oriented, autonomous execution. This paper explores the emergence of the “ghost student”: a digital surrogate created by the coupling of Large Language Models (the “mind”) and agentic AI browsers (the “body”). These entities are capable of navigating Learning Management Systems (LMS), engaging with content, and completing assessments with human-like mimicry, often rendering the actual learner’s presence optional. We argue that this phenomenon creates a verification gap that traditional proctoring and detection tools are structurally unable …

Trial By Character, Hillel J. Bavli

Faculty Journal Articles and Book Chapters

In this Article, I argue that courts regularly deviate from Federal Rule of Evidence 404(b), which prohibits character evidence—evidence of a defendant’s past misdeeds offered to prove that the defendant acted in conformity with a certain character trait on the occasion in question. These deviations undermine the fairness of a trial and the presumption of innocence. The Article addresses this problem in three ways. First, it explains how courts have misinterpreted Rule 404(b)—an error that I call the permitted-purpose fallacy—and how they have fortified this misinterpretation with a body of flawed principles and precedent. Second, it reports the results of …

Youtube Journalists And The Future Of The Fourth Estate: The Fine Line Between Journalism And Entertainment, Stephan Toljan

Cardozo Arts & Entertainment Law Journal

The note argues that the legal distinction between professional journalists and social media actors has blurred due to the universal accessibility of public digital platforms. It proposes eliminating the requirement of institutional affiliation for the reporter's privilege, suggesting instead that any individual who satisfies the Von Bulow factors regarding the intent to disseminate information to the public should be eligible for the privilege.

Expert Asymmetry: Evidence From Securities Litigation, Adam Callister, Andrew Granato, Belisa Pang

Faculty Publications

Modern litigation often involves two separate, extra-legal features: (1) contingency fee arrangements with the plaintiff-side attorney, and (2) a “battle of the experts” where the outcome of the case rests on conflicting expert witness testimony. We construct a model to illustrate that when these features occur simultaneously, in contexts where plaintiff-side attorneys bear the cost of hiring experts upfront, defendants will spend systematically more than plaintiffs on hiring expert witnesses. Our model is motivated by hand-collected data from a decade of securities class action litigation, where we show that experts polarize into almost entirely plaintiff-side versus defense-side experts, that defense-side …

Let’S Talk About The Biological Reality Of Sex, Baby, John Parsi

FIU Law Review

Sex is at the very core of individual identity. It affects the conception of the self and the way others view the individual. Every day, one’s sex may open and close doors, access to communities, and opportunities. Laws that define sex may affirm scientific knowledge and protect people, or threaten to unravel the facts and the reality of sex. A deep unmooring of sex is underway, and this Article aims to halt it. On day one of the current presidential term, January 20, 2025, President Trump signed an Executive Order on “Defending Women from Gender Ideology Extremism and Restoring Biological …

Automated Writer And Acquisition-Condition Classification Of Digitally Captured Handwriting Using Statistical Dynamic Features And Support Vector Machines, Long-Huang Tsai, Hsiang-Ju Lai, Wen-Chao Yang, Jiajun Jiang, Chung-Hao Chen

Electrical & Computer Engineering Faculty Publications

Digitally captured handwriting preserves pen trajectories and dynamic signals, but it also records hardware- and input-dependent properties that can confound forensic interpretation. This study revises a support vector machine (SVM) screening framework using 16,500 samples from 30 writers, 11 writing-content categories, and five acquisition conditions spanning three tablets and stylus or finger input. Twenty-four raw and derived time-series variables were summarized by maximum, minimum, mean, median, and standard deviation, yielding 120 features; the mode statistic was removed. Writing direction and angular velocity were recalculated with atan2-based vector formulas. Unavailable device/API channels were encoded as zero, and Z-score parameters were estimated …

Misinformation And The Law, Gustavo Ribeiro

Scholarly Articles in Law Reviews & Journals

This Article bridges critical gaps between the growing body of social science research on misinformation and the persistent challenges jurors face in evaluating potentially unreliable evidence in courtrooms. Misinformation—a pervasive issue undermining decision-making in democratic societies—mirrors the difficulties jurors encounter in distinguishing truth from falsehood amid compelling but unreliable evidence. The consequences of such challenges are dire: wrongful convictions, racial disparities, and the erosion of public trust in the legal system.

This Article is the first piece of legal scholarship to provide a comprehensive discussion of current research on the psychological mechanisms underlying susceptibility to misinformation—such as the illusory truth …

Evidence: The Limits Of Limiting Forensic Firearm-Identification Testimony, David L. Faigman

The Judges' Book

For more than a century, firearm examiners have testified in unequivocal terms that they can match bullets or cartridge cases to a specific firearm, often asserting identification “to the practical exclusion of all other firearms.” These claims were widely accepted in courts and rarely subjected to empirical validation.

Over the past two decades, however, they have come under increasing scrutiny from scientists, legal scholars, and government bodies. In particular, scientific reviews of the research basis for firearms and toolmark identification have found that the data do not support such claims of “individualization.” Examiners can identify the type or class of …

Brady's Shadow, Justin Murray

Publications

Scholars have spent sixty years documenting Brady v. Maryland’s failures—its materiality standard that licenses suppression of exculpatory evidence, its abandonment of defendants who plead guilty, its toothless enforcement. Yet these same critics celebrate Brady’s supposed grand promise, treating the decision’s incarnate presence as the betrayal of an ideal rather than recognizing the promise itself as a mirage. This Article contends that our profession’s faith in Brady—even faith expressed through demands for reform—perpetuates the very dysfunction it critiques. Brady operates not merely as failed doctrine but as a trap and a shadow: the trap springs when its mythology …

A Zealous Advocate, A Robust Cross: Cross-Examination Of Non-Adverse Witnesses By The Guardian Ad Litem, Scott Swain

BYU Law Review

“When the lives and fundamental rights of children are at stake, there must be no silent witnesses.”1 — Carol Bellamy

Systemic pressures in child welfare litigation regularly lead guardian ad litem attorneys to default to the positions and recommendations of state social services. In such cases, witnesses called by the state in trials and evidentiary hearings are non-adverse to the guardian ad litem. This dynamic undermines the purposes of cross-examination rules, threatening the procedural interests of the parties involved. This paper will use a procedural due process balancing test to guide its analysis as it proposes three potential solutions: a …

The Rise And [?] Of Anti-Administrativism, Gary Lawson

BYU Law Review

Scholars have proclaimed the administrative state to be “Under Siege” or subject to a “Never-Ending Assault.” Was the election of President Donald Trump on November 5, 2024, the sixth, if not yet the seventh, day around the walls?

This seems an appropriate time to consider the present and future of opposition to the administrative state—something that has come to be dubbed “anti-administrativism.” The first task, as is usually the case when one seeks intellectual clarity, is to figure out what one is talking about. What is this “anti-administrativism”? Without knowing the answer to that seemingly simple question, one cannot accurately …

Textualist Reasoning And The Open Fields Doctrine: A Survey Of State-Constitutional Decisions, Ariel Krogue

BYU Law Review

State constitutions can, and often do, provide more extensive individual rights than the Federal Constitution affords. When this occurs, state courts frequently cite textual differences between the Federal Constitution and their own state constitutions to explain their departures from federal norms. But do textual differences between the Federal Constitution and state constitutions actually explain why some states offer more constitutional protection than the federal government does? When it comes to the Fourth Amendment’s open fields doctrine, the answer is no.

This Note provides a fifty-state survey of state-constitutional search and seizure provisions; it also identifies those states that have rejected …

Between Relevance And Remedy: Trial Court Discretion In Georgia Evidence Law, John E. Hall Jr., W. Scott Henwood, Rebekah Mabe

Mercer Law Review

The admissibility of evidence in Georgia civil litigation continues to rest on a foundational principle: deference to the trial court’s discretion. Georgia appellate courts have consistently reaffirmed that evidentiary rulings—particularly those involving complex or fact-sensitive considerations—will not be disturbed absent a clear abuse of discretion. This standard reflects the institutional competence of trial courts, which are uniquely positioned to evaluate the credibility of parties, assess the probative value of evidence, and manage the presentation of issues throughout the course of litigation. While portions of Georgia’s Evidence Code closely mirror the Federal Rules of Evidence—permitting persuasive use of federal case law …
