Evidentiary Inequality, Sandra F. Sperino

Faculty Publications

Federal employment discrimination law is rife with evidentiary inequality. Courts allow employers to draw from a broad palette of evidence to defend against discrimination claims, while highly restricting the facts from which plaintiffs can prove their claims. This Article draws from hundreds of cases to show how judges favor the employer's evidence and disfavor the plaintiff's evidence across multiple dimensions, such as time, witnesses, documents, relevance, and reliability. Judges have created a host of named doctrines that severely restrict the evidence plaintiffs are allowed to use to prove their discrimination claims. At the same time, a host of unnamed, and …

Issue Of False Amphetamine Field Test Positives Caused By Sugar. Use Of Baeyer Test As A Secondary Test Solution., Reed A. Knutson, Jennah Duncan, Kara Peightal, Samuel Thomas

Chemistry Department: Dissertations, Theses, and Student Research

The Marquis reagent is a well-established and widely used chemical presumptive test for 3,4-Methylenedioxymethamphetamine (MDMA) and methamphetamine. It is composed of concentrated sulfuric acid and 40% formaldehyde, which act upon alkaloids causing them to complex into larger molecules. This complexation causes a color change that can be visually interpreted as a positive or negative result. Almost any sugar molecule can be complexed in this way as well, due to their many OH groups. Experimentally it was found that the sugar molecules did complex with one another when the Marquis test was administered. The color produced by this reaction was brownish-red. …

The Modest Impact Of The Modern Confrontation Clause, Jeffrey Bellin, Diana Bibb

Faculty Publications

The Sixth Amendment's Confrontation Clause grants criminal defendants the right "to be confronted with the witnesses against" them. A strict reading of this text would transform the criminal justice landscape by prohibiting the prosecution's use of hearsay at trial. But until recently, the Supreme Court's interpretation of the Clause was closer to the opposite. By tying the confrontation right to traditional hearsay exceptions, the Court's longstanding precedents granted prosecutors broad freedom to use out-of-court statements to convict criminal defendants.

The Supreme Court's 2004 decision in Crawford v. Washington was supposed to change all that. By severing the link between the …

Minding Accidents, Teneille R. Brown

Utah Law Faculty Scholarship

Tort doctrine states that breach is all about conduct. Unlike in the criminal law, where jurors must engage in an amateur form of mindreading to evaluate mens rea, jurors are told that they can assess civil negligence by looking only at how the defendant behaved. But this is false. Foreseeability is at the heart of negligence—appearing as the primary tests for duty, breach, and proximate cause. And yet, we cannot ask whether a defendant should have foreseen a risk without interrogating what he subjectively knew, remembered, perceived, or realized at the time. In fact, the focus on actions in negligence …

Antitrust Harm And Causation, Herbert J. Hovenkamp

All Faculty Scholarship

How should plaintiffs show harm from antitrust violations? The inquiry naturally breaks into two issues: first, what is the nature of the harm? and second, what does proof of causation require? The best criterion for assessing harm is likely or reasonably anticipated output effects. Antitrust’s goal should be output as high as is consistent with sustainable competition.

The standard for proof of causation then depends on two things: the identity of the enforcer and the remedy that the plaintiff is seeking. It does not necessarily depend on which antitrust statute the plaintiff is seeking to enforce. For public agencies, enforcement …

Servotronics, Inc. V. Rolls-Royce Plc And The Boeing Company: Brief Of Professor Yanbai Andrea Wang As Amicus Curiae In Support Of Neither Party, Yanbai Andrea Wang, Michael H. Mcginley

All Faculty Scholarship

Rather than expressing a view on the issues raised and ably briefed by the parties, amicus submits this brief to inform the Court of the scholarly research she has conducted regarding Section 1782 proceedings since this Court’s seminal decision in Intel. As Section 1782 applications have proliferated, the lower courts have struggled to apply the Intel factors as this Court had envisioned. Especially in the context of Section 1782 applications submitted by parties to an international proceeding (as opposed to those made by the international tribunal itself), lower courts have frequently found themselves unable to analyze and apply the …

Recollections Refreshed And Recorded, Len Niehoff

Articles

Witnesses forget stuff. When they do, the evidence rules give us two tools to help solve the problem. Lawyers call one "refreshed recollection" and the other "past recollection recorded," labels just similar enough to guarantee confusion. Nevertheless, these principles get at very different things and are well worth the effort necessary to distinguish and understand them. So how do we get there?

Scientific Gerrymandering & Bifurcation, Katrina F. Kuh, Megan Edwards, Frederick A. Mcdonald

Elisabeth Haub School of Law Faculty Publications

Environmental litigation must often examine the propriety of corporate conduct in areas of scientific complexity. In the second generation of climate nuisance suits, for example, allegations of corporate participation in the climate disinformation campaign are woven into plaintiffs’ claims. Toxic tort suits, currently and most notably in the Roundup and PFAS litigation, present another area of environmental litigation grappling with the legal ramifications of alleged corporate deception about scientific information. Toxic tort suits often surface allegations, and in many cases disturbing evidence, of what we term corporate “scientific gerrymandering”— corporate efforts to finesse, slow, or even mislead scientific understanding of …

Do You See What I See? The Science Behind Utah Rule Of Evidence 617, Louisa Heiny

Utah Law Faculty Scholarship

Eyewitness identifications play a key role in many investigations and are often central to a prosecutor’s case. At the same time, eyewitness identifications can be tainted, accidentally or purposely, thus tainting the justice system as well. There are myriad reasons for this phenomenon, but the primary responsibility lies not with the witness, but rather a system that fails to recognize, and often amplifies, mistakes and assumptions in the identification process.

Power And Statistical Significance In Securities Fraud Litigation, Jill E. Fisch, Jonah B. Gelbach

All Faculty Scholarship

Event studies, a half-century-old approach to measuring the effect of events on stock prices, are now ubiquitous in securities fraud litigation. In determining whether the event study demonstrates a price effect, expert witnesses typically base their conclusion on whether the results are statistically significant at the 95% confidence level, a threshold that is drawn from the academic literature. As a positive matter, this represents a disconnect with legal standards of proof. As a normative matter, it may reduce enforcement of fraud claims because litigation event studies typically involve quite low statistical power even for large-scale frauds.

Junk Science At Sentencing, Maneka Sinha

Faculty Scholarship

Junk science used in criminal trials has contributed to hundreds of wrongful convictions. But the problem is much worse than that. Junk science does not only harm criminal defendants who go to trial, but also the overwhelming majority of defendants—over ninety-five percent—who plead guilty, skip trial, and proceed straight to sentencing.

Scientific, technical, and other specialized evidence (“STS evidence”) is used regularly, and with increasing frequency, at sentencing. Despite this, Federal Rule of Evidence 702 and its state equivalents—which help filter unreliable STS evidence at trials—do not apply at the critical sentencing stage. In fact, at sentencing, no meaningful admissibility …

The Euclid Proviso, Ezra Rosser

Articles in Law Reviews & Other Academic Journals

This Article argues that the Euclid Proviso, which allows regional concerns to trump local zoning when required by the general welfare, should play a larger role in zoning's second century. Traditional zoning operates to severely limit the construction of additional housing. This locks in the advantages of homeowners but at tremendous cost, primarily in the form of unaffordable housing, to those who would like to join the community. State preemption of local zoning defies traditional categorization; it is at once both radically destabilizing and market-responsive. But, given the ways in which zoning is a foundational part of the racial and …

Know Every Document And Piece Of Evidence In Your File, Rachel Brockl

Publications

Knowing every document and piece of evidence in your case file is imperative to competent preparation of your case. While this may sound obvious, many attorneys fail to follow this advisement to their own peril. The reasons for knowing your case file in and out are threefold: (1) you want to be the case master, (2) you do not want to be caught off-guard, and (3) your reputation is on the line.

The Disruption Of Covid-19: How A Virtual World Creates Opportunity For Improvement In The Criminal Justice System’S Treatment Of Complainants Of Sexual Violence, Leah Roberston

Law in a Post-Pandemic World

This paper argues that the COVID-19 pandemic has normalized video conferencing within the legal system such that survivors ought to be able to routinely testify outside of the court environment. Though there have always been high rates of sexualized violence, the onset of the pandemic has led to increased rates of sexualized violence, which could lead to greater numbers of trials prosecuting perpetrators. However, only a small amount of complainants turn to the court as a form of justice. This is likely due to the inhumane conditions inflicted on complainants during the trial process. The pandemic has revealed that the …

Why Illinois Should Reevaluate Its Video Tolling (V-Toll) Subsidy, Randall K. Johnson

Faculty Works

Tolls are levies with a limited base. This base is made up of drivers that pay user fees, in cash or via electronic transponder, in exchange for access to state-administered roads. In Illinois, every single toll is a function of three factors: vehicle characteristics, tollway entry point, and how far a driver goes on state-administered roads.

It is commonly assumed that any toll violation, i.e., any failure to pay, results in a traffic ticket, administrative fees and state-imposed sanctions. Such an assumption, however, is only partly true due to overly forgiving Illinois state policies. Examples include the Traffic Ticket Exemption, …

#Believewomen And The Presumption Of Innocence: Clarifying The Questions For Law And Life, Kimberly Kessler Ferzan

All Faculty Scholarship

The presumption of innocence and #BelieveWomen both embody compelling considerations, and we may wonder how to reconcile them. My project does not aim to reconcile the positions, but rather, it is prior to it. My goal in this paper is to better explicate the claims that underlie both #BelieveWomen and the presumption of innocence in law and life, as well as to identify instances in which cross-pollination, between our everyday evaluations and the legal system, is contaminating our thinking.

First, I begin with #BelieveWomen and sort through various ways to interpret this demand (though my survey is not exhaustive). I …

Exposing Police Misconduct In Pre-Trial Criminal Proceedings, Anjelica Hendricks

All Faculty Scholarship

This Article presents a unique argument: police misconduct records should be accessible and applicable for pre-trial criminal proceedings. Unfortunately, the existing narrative on the value of police misconduct records is narrow because it exclusively considers how these records can be used to impeach officer credibility at trial. This focus is limiting for several reasons. First, it addresses too few defendants, since fewer than 3% of criminal cases make it to trial. Second, it overlooks misconduct records not directly addressing credibility—such as records demonstrating paperwork deficiencies, failures to appear in court, and “mistakes” that upon examination are patterns of abuse. Finally, …

The Easterbrook Theorem: An Application To Digital Markets, Joshua D. Wright, Murat C. Mungan

Faculty Scholarship

The rise of large firms in the digital economy, including Amazon, Apple, Facebook, and Google, has rekindled the debate about monopolization law. There are proposals to make finding liability easier against alleged digital monopolists by relaxing substantive standards; to flip burdens of proof; and to overturn broad swaths of existing Supreme Court precedent, and even to condemn a law review article. Frank Easterbrook’s seminal 1984 article, The Limits of Antitrust, theorizes that Type I error costs are greater than Type II error costs in the antitrust context, a proposition that has been woven deeply into antitrust law by the Supreme …

Completing The Quantum Of Evidence, Edward K. Cheng

Vanderbilt Law School Faculty Publications

In "Evidentiary Irony and the Incomplete Rule of Completeness," Professors Daniel Capra and Liesa Richter comprehensively catalog the many shortcomings in current Federal Rule of Evidence 106 and craft a compelling reform proposal. Their proposal admirably solves the identified problems, keeps the rule reasonably succinct, and furthers the accuracy and fairness goals of the rules of evidence. In this Response, we focus on Capra & Richter's proposal to formally recognize a "trumping" power in Rule 106, which would allow an adverse party to offer a completing statement even if it would be "otherwise inadmissible under the rule against hearsay."

The Functional Operation Of Workers’ Compensation Covid Presumptions, Michael C. Duff

All Faculty Scholarship

During 2020, a number of U.S. states implemented workers' compensation COVID-19 presumptions. This short informal paper defines and explains legal presumptions generally and then discusses the workers' compensation presumptions. The paper contends that at this juncture it is not clear whether states intended to enact "Thayer-Wigmore" or "Morgan" presumptions; but if they operate as Thayer-Wigmore presumptions they will not do workers' compensation claimants much good in the context of non-jury proceedings presided over by administrative law judges.

“Rule Of Inclusion" Confusion, Dora Klein

Faculty Articles

Some rules of evidence are complex. The federal rules governing the admissibility of hearsay statements,' for example, include at least forty different provisions. Numerous judges and scholars have commented on the complexity of the hearsay rules. Not all rules of evidence are complex, however. For example, the federal rules governing the admissibility of character evidence are relatively straightforward: evidence that is offered for the purpose of proving character is inadmissible, subject to a few well-defined exceptions. Despite this relative straightforwardness, many of the federal circuit courts of appeals have overlaid the rules regarding character evidence particularly Rule 404(b)--with unnecessary interpretive …

The Evidence Rules That Convict The Innocent, Jeffrey Bellin

Faculty Publications

Over the past decades, DNA testing has uncovered hundreds of examples of the most important type of trial errors: innocent defendants convicted of serious crimes like rape and murder. The resulting Innocence Movement spurred reforms to police practices, forensic science, and criminal procedure. This Article explores the lessons of the Innocence Movement for American evidence law.

Commentators often overlook the connection between the growing body of research on convictions of the innocent and the evidence rules. Of the commonly identified causes of false convictions, only flawed forensic testimony has received sustained attention as a matter of evidence law. But other …

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

Faculty Scholarship

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 …
