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

Faculty Scholarship

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 …

Race, Gatekeeping, Magical Words, And The Rules Of Evidence, I. Bennett Capers

Faculty Scholarship

Although it might not be apparent from the Federal Rules of Evidence themselves, or the common law that preceded them, there is a long history in this country of tying evidence—what is deemed relevant, what is deemed trustworthy—to race. And increasingly, evidence scholars are excavating that history. Indeed, not just excavating, but showing how that history has racial effects that continue into the present.

One area that has escaped racialized scrutiny—at least of the type I am interested in—is that of expert testimony. In this brief Essay written for the Vanderbilt Law Review Symposium, Reimagining the Rules of Evidence at …

Binding Hercules: A Proposal For Bench Trials, Maggie Wittlin

Faculty Scholarship

Should the Federal Rules of Evidence apply at bench trials? By their own terms, they apply, but courts have been reluctant to enforce them on themselves with the same rigor that they enforce them on juries. Scholarship on the issue has been mixed. Although McCormick deemed the rules of evidence "absurdly inappropriate" outside of the jury context, more recently, scholars have suggested that many reasons for imposing exclusionary rules on jurors also apply to judges. Yet practical problems persist. For one, once judge evaluate the admissibility of evidence, they can’t “unring the bell” and ignore evidence they've decided to exclude. …

Theorizing Corroboration, Maggie Wittlin

Faculty Scholarship

A child makes an out-of-court statement accusing an adult of abuse. That statement is important proof, but it also presents serious reliability concerns. When deciding whether it is sufficiently reliable to be admitted, should a court consider whether the child’s statement is corroborated—whether, for example, there is medical evidence of abuse? More broadly, should courts consider corroboration when deciding whether evidence is reliable enough to be admitted at trial? Judges, rule-makers, and scholars have taken significantly divergent approaches to this question and come to different conclusions.

This Article argues that there is a key problem with using corroboration to evaluate …

A History Of Fruit Of The Poisonous Tree (1916-1942), Daniel B. Yeager

Faculty Scholarship

This is a history of a little-known stage within an otherwise well-known area of criminal procedure. The subject, “fruit of the poisonous tree,” explains the exclusion from trial of evidence (the fruit) derived from unconstitutional police practices (the tree). The Supreme Court first deployed the metaphor in 1939; exclusion of fruits by any other name, however, dates to before the Court began reviewing state convictions. While academic interest in the 1963-to-present phase of fruits is keen, the first quarter of what is now a century of history is taken as given, described in only the most conclusory terms. The 1916–1942 …

The Living Rules Of Evidence, G. Alexander Nunn

Faculty Scholarship

The jurisprudential evolution of evidence law is dead. At least, that’s what we’re expected to believe. Ushered in on the wings of a growing positivist movement, the enactment of the Federal Rules of Evidence purported to quell judicial authority over evidence law. Instead, committees, conferences, and members of Congress would regulate any change to our evidentiary regime, thereby capturing the evolution of evidence law in a single, transparent code.

The codification of evidence law, though, has proven problematic. The arrival of the Federal Rules of Evidence has given rise to a historically anomalous era of relative stagnation in the doctrinal …

The Entity Attorney-Client Privilege Meets The Twenty-First Century: Rethinking Functional Equivalent Analysis In The Time Of A Nonemployee Workforce., Grace M. Giesel

Faculty Scholarship

Courts have struggled with whether an entity’s attorney-client privilege can protect communications between the entity’s lawyer and a nonemployee who has information the entity’s lawyer needs to best advise the entity. The nonemployee might be a former employee. But increasingly in recent times, the nonemployee is an individual who was never an entity employee. Corporations and other entities have incorporated nonemployees in their economic enterprises in all sorts of roles—roles employees may have held in the past. Many courts have accepted that the privilege can apply to communications involving former employees.

When faced with nonemployees who are not former employees, …

Law, Fact, And Procedural Justice, G. Alexander Nunn

Faculty Scholarship

The distinction between questions of law and questions of fact is deceptively complex. Although any first-year law student could properly classify those issues that fall at the polar ends of the law-fact continuum, the Supreme Court has itself acknowledged that the exact dividing line between law and fact—the point where legal inquiries end and factual ones begin—is “slippery,” “elusive,” and “vexing.” But identifying that line is crucially important. Whether an issue is deemed a question of law or a question of fact often influences the appointment of a courtroom decision maker, the scope of appellate review, the administration of certain …

The Use Of Technical Experts In Software Copyright Cases: Rectifying The Ninth Circuit’S “Nutty” Rule, Shyamkrishna Balganesh, Peter S. Menell

Faculty Scholarship

Courts have long been skeptical about the use of expert witnesses in copyright cases. More than four decades ago, and before Congress extended copyright law to protect computer software, the Ninth Circuit in Krofft Television Productions, Inc. v. McDonald’s Corp. ruled that expert testimony was inadmissible to determine whether Mayor McCheese and the merry band of McDonald’s characters infringed copyright protection for Wilhelmina W. Witchiepoo and the other imaginative H.R. Pufnstuf costumed characters. Since the emergence of software copyright infringement cases in the 1980s, substantially all software copyright cases have permitted expert witnesses to aid juries in understanding software code. …

Machine-Generated Evidence, G. Alexander Nunn

Faculty Scholarship

Person-based evidence is no longer the monolith it once was. With technological advancement has come the rise of so-called "machine-generated evidence." Unlike traditional forms of evidence, the reliability of machine-generated evidence primarily depends not on any person’s actions—neither the quality of their perceptions nor their ability to carry out tasks—but instead on the standardized processes and mechanisms internal to the machine that produced it. As technological advancement continues apace, and new, innovative forms of machine-generated evidence reach the courtroom, judges and lawyers will be required to respond in two important ways.

First must come awareness of the unique nature of …

Race And Reasonableness In Police Killings, Jeffrey A. Fagan, Alexis D. Campbell

Faculty Scholarship

Police officers in the United States have killed over 1000 civilians each year since 2013. The constitutional landscape that regulates these encounters defaults to the judgments of the reasonable police officer at the time of a civilian encounter based on the officer’s assessment of whether threats to their safety or the safety of others requires deadly force. As many of these killings have begun to occur under similar circumstances, scholars have renewed a contentious debate on whether police disproportionately use deadly force against African Americans and other nonwhite civilians and whether such killings reflect racial bias. We analyze data on …

Beyond The Witness: Bringing A Process Perspective To Modern Evidence Law, Edward K. Cheng, G. Alexander Nunn

Faculty Scholarship

The focal point of the modern trial is the witness. Witnesses are the source of observations, lay and expert opinions, authentication, as well as the conduit through which documentary, physical, and scientific evidence is introduced. Evidence law therefore unsurprisingly concentrates on – or perhaps obsesses over – witnesses. In this Article, we argue that this witness-centered perspective is antiquated and counterproductive. As a historical matter, focusing on witnesses may have made sense when most evidence was the product of individual observation and action. But the modern world frequently features evidence produced through standardized, objective, and even mechanical processes that largely …

The Disappointing History Of Science In The Courtroom: Frye, Daubert, And The Ongoing Crisis Of “Junk Science” In Criminal Trials, Jim Hilbert

Faculty Scholarship

Twenty-five years ago, the Supreme Court decided one of the most important cases concerning the use of science in courtrooms. In Daubert v. Merrell Dow Pharmaceuticals , the Court addressed widespread concerns that courts were admitting unreliable scientific evidence. In addition, lower courts lacked clarity on the status of the previous landmark case for courtroom science, Frye v. United States. In the years leading up to the Daubert decision, policy-makers and legal observers sounded the alarm about the rise in the use of "junk science" by so-called expert witnesses. Some critics went so far as to suggest that American businesses …

Activist Directors And Agency Costs: What Happens When An Activist Director Goes On The Board?, John C. Coffee Jr., Robert J. Jackson Jr., Joshua Mitts, Robert Bishop

Faculty Scholarship

We develop and apply a new and more rigorous methodology by which to measure and understand both insider trading and the agency costs of hedge fund activism. We use quantitative data to show a systematic relationship between the appointment of a hedge fund nominated director to a corporate board and an increase in informed trading in that corporation’s stock (with the relationship being most pronounced when the fund’s slate of directors includes a hedge fund employee). This finding is important from two different perspectives. First, from a governance perspective, activist hedge funds represent a new and potent force in corporate …

The Last Refuge Of Scoundrels: The Problem Of Truth In A Time Of Lying, Bernard E. Harcourt

Faculty Scholarship

This essay addresses the problem of truth today in light of the common belief, especially among progressives, that we have entered a post-truth age, as well as of the frequent claim that our post-truth society is the fault of postmodernists and their challenge to the objectivity of truth. The essay does not resolve the strategic question whether the post-truth argument is, as a purely tactical political matter, an effective approach to respond to the onslaught of misrepresentations and lies by President Donald Trump and the New Right. Instead, it explores the post-truth argument from a more synoptic perspective regarding the …

Control Of The Attorney-Client Privilege After Mergers And Other Transformational Transactions: Should Control Of The Privilege Be Alienable By Contract?, Grace M. Giesel

Faculty Scholarship

In recent years, parties to mergers and other transformational transactions have begun inserting into their deal documents provisions allocating post-transaction control of the attorney-client privilege for pretransaction communications. The controller of the privilege is the person or entity who decides whether to assert the privilege or, rather, to waive it. Commonly, representatives of the target entity in a merger or representatives of an asset seller in a transformational sale want post-transaction control of the privilege for pre-transaction communications relating to the transaction. They want control of the privilege so the surviving entity cannot access or use those communications against the …

The Ideological Roots Of America's Market Power Problem, Lina M. Khan

Faculty Scholarship

Mounting research shows that America has a market power problem. In sectors ranging from airlines and poultry to eyeglasses and semiconductors, just a handful of companies dominate. The decline in competition is so consistent across markets that excessive concentration and undue market power now look to be not an isolated issue but rather a systemic feature of America’s political economy. This is troubling because monopolies and oligopolies produce a host of harms. They depress wages and salaries, raise consumer costs, block entrepreneurship, stunt investment, retard innovation, and render supply chains and complex systems highly fragile. Dominant firms’ economic power allows …

A ‘Bad Rap’: R. V. Skeete And The Admissibility Of Rap Lyric Evidence, Ngozi Okidegbe

Faculty Scholarship

The use of accused-authored rap lyric evidence is no longer rare in Canadian criminal proceedings. Adduced by Crown prosecutors, rap lyrics written or co-written by an accused are increasingly used in criminal trials as evidence of the accused’s intent, knowledge, motive, identity, or confession to the commission of the specific offence charged. The practice is not without controversy.¹ The introduction of an accused’s artistic work in the form of rap lyrics at trial engages trial fairness concerns. Without a keen awareness of the social and cultural context that produces rap music, trial actors risk inflating their probative value and …

Racial Character Evidence In Police Killing Cases, Jasmine Gonzales Rose

Faculty Scholarship

The United States is facing a twofold crisis: police killings of people of color and unaccountability for these killings in the criminal justice system. In many instances, the officers’ use of deadly force is captured on video and often appears clearly unjustified, but grand and petit juries still fail to indict and convict, leaving many baffled. This Article provides an explanation for these failures: juror reliance on “racial character evidence.” Too often, jurors consider race as evidence in criminal trials, particularly in police killing cases where the victim was a person of color. Instead of focusing on admissible evidence, jurors …

Reducing Wasteful Incarcerations, Christopher Robertson

Faculty Scholarship

Prisons are essential to a safe and civil society. Prisons are also costly for the taxpayers whose government houses, feeds, medicates, and supervises millions of people underlock and key.This expense is compounded by errors in the u.S. legal system that produces both false guilty verdicts and overly harsh penalties. It’stime forthe united States to take a closer look at these unnecessary incarcerations. By working to release prisoners who don’t belong in prison, we can lower the costs of the prison system—not to mention restore freedom to people who are wrongly being deprived of it. unfortunately, it is difficult to identify …

G2i Knowledge Brief: A Knowledge Brief Of The Macarthur Foundation Research Network On Law And Neuroscience, David L. Faigman, Anthony Wagner, Richard J. Bonnie, Bj Casey, Andre Davis, Morris B. Hoffman, Owen D. Jones, Read Montague, Stephen J. Morse, Marcus E. Raichle, Jennifer A. Richeson, Elizabeth S. Scott, Laurence Steinberg, Kim Taylor-Thompson, Gideon Yaffe

Faculty Scholarship

Courts are daily confronted with admissibility issues – such as in cases involving neuroscientific testimony – that sometimes involve both the existence of a general phenomenon (i.e., “G”) and the question of whether a particular case represents a specific instance of that general phenomenon (i.e., “i”).

Unfortunately, courts have yet to carefully consider the implications of “G2i” for their admissibility decisions. In some areas, courts limit an expert’s testimony to the general phenomenon. They insist that whether the case at hand is an instance of that phenomenon is exclusively a jury question, and thus not an appropriate subject of expert …

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 …

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 …

Some studies have reported the ability to detect lies, with a high degree of accuracy, by analyzing brain data acquired using functional magnetic resonance imaging (fMRI). But is this new technology ready for its day in court?

This consensus knowledge brief from the MacArthur Foundation Research Network on Law and Neuroscience takes a closer look at the potential and pitfalls of fMRI lie detection techniques, providing insight into the areas of the brain involved in lying, the impact of memory on deception, how countermeasures may foil our efforts to detect lies, and factors that can create cause for concern about …

The Incompatibility Of Due Process And Naked Statistical Evidence, G. Alexander Nunn

Faculty Scholarship

Numerous articles and commentaries have grappled with an undeniable feeling of injustice that comes from wrestling with naked statistical evidence. Even if, from a purely quantitative standpoint, the weight of the evidence supports the imposition of liability on a defendant, the sole use of probabilities to assess this liability seems innately unfair. This tension has spawned a great debate that questions the role of naked statistical evidence in today’s legal system. Contributing to this discourse, this Note argues that, in certain circumstances, the use of naked statistical evidence constitutes a due process violation. United States circuit courts have held that …
