#Wetoo, Kimberly Kessler Ferzan

All Faculty Scholarship

The #MeToo movement has caused a widespread cultural reckoning over sexual violence, abuse, and harassment. “Me too” was meant to express and symbolize that each individual victim was not alone in their experiences of sexual harm; they added their voice to others who had faced similar injustices. But viewing the #MeToo movement as a collection of singular voices fails to appreciate that the cases that filled our popular discourse were not cases of individual victims coming forward. Rather, case after case involved multiple victims, typically women, accusing single perpetrators. Victims were believed because there was both safety and strength in …

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 …

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.

This paper, written for …

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, …

Sexual Consent And Disability, Jasmine E. Harris

All Faculty Scholarship

Our nation is engaged in deep debate over sexual consent. But to date the discussion has overlooked sexual consent’s implications for a key demographic: people with mental disabilities, for whom the reported incidence of sexual violence is three times that of the nondisabled population. Even as popular debate overlooks the question of sexual consent for those with disabilities, contemporary legal scholars critique governmental overregulation of this area, arguing that it diminishes the agency and dignity of people with disabilities. Yet in defending their position, these scholars rely on empirical data from over twenty years ago, when disability and sexual assault …

The Logic And Limits Of Event Studies In Securities Fraud Litigation, Jill E. Fisch, Jonah B. Gelbach, Jonathan Klick

All Faculty Scholarship

Event studies have become increasingly important in securities fraud litigation after the Supreme Court’s decision in Halliburton II. Litigants have used event study methodology, which empirically analyzes the relationship between the disclosure of corporate information and the issuer’s stock price, to provide evidence in the evaluation of key elements of federal securities fraud, including materiality, reliance, causation, and damages. As the use of event studies grows and they increasingly serve a gatekeeping function in determining whether litigation will proceed beyond a preliminary stage, it will be critical for courts to use them correctly.

This Article explores an array of …

Neuroscience In Forensic Contexts: Ethical Concerns, Stephen J. Morse

All Faculty Scholarship

This is a chapter in a volume, Ethics Challenges in Forensic Psychiatry and Psychology Practice, edited by Ezra E. H. Griffith, M.D. and to be published by Columbia University Press. The chapter addresses whether the use of new neuroscience techniques, especially non-invasive functional magnetic resonance imaging (fMRI) and the data from studies employing them raise new ethical issues for forensic psychiatrists and psychologists. The implicit thesis throughout is that if the legal questions, the limits of the new techniques and the relevance of neuroscience to law are properly understood, no new ethical issues are raised. A major ethical lapse …

Actions Speak Louder Than Images: The Use Of Neuroscientific Evidence In Criminal Cases, Stephen J. Morse

All Faculty Scholarship

This invited commentary for Journal of Law & the Biosciences considers four empirical studies previously published in the journal of the reception of neuroscientific evidence in criminal cases in the United States, Canada, England and Wales, and the Netherlands. There are conceded methodological problems with all, but the data are nonetheless instructive and suggestive. The thesis of the comment is that the courts are committing the same errors that have bedeviled the reception of psychiatric and psychological evidence. There is insufficient caution about the state of the science, and more importantly, there is insufficient understanding of the relevance of the …

Conviction Review Units: A National Perspective, John Hollway

All Faculty Scholarship

Over the past 25 years, Americans have become increasingly aware of a vast array of mistakes in the administration of justice, including wrongful convictions, situations where innocent individuals have been convicted and incarcerated for crimes they did not commit. The most prevalent institutional response by prosecutors to address post-conviction fact-based claims of actual innocence is the Conviction Review Unit (CRU), sometimes called the Conviction Integrity Unit. Since the creation of the first CRU in the mid-2000s, more than 25 such units have been announced across the country; more than half of these have been created in the past 24 months. …

The Role Of Support In Sexual Decision-Making For People With Intellectual And Developmental Disabilities, Jasmine E. Harris

All Faculty Scholarship

In response to Alexander Boni-Saenz, Sexuality and Incapacity, 76 Ohio St. L.J. 1201 (2015).

This Response analyzes three aspects of Boni-Saenz’s cognition-plus test. First, I position his normative and prescriptive proposals within an existing, robust conversation regarding legal capacity, SDM, and the United Nations Convention on the Rights of Persons with Disabilities (CRPD). Scholars of international human rights law offer valuable insights on challenges of redefining legal capacity and implementing SDM. Advocates continue to debate and contest SDM as a practical, administrable, and measurable alternative. Second, I identify potential normative implications of incorporating SDM into domestic law, specifically for …

The Importance Of Being Dismissive: The Efficiency Role Of Pleading Stage Evaluation Of Shareholder Litigation, Lawrence A. Hamermesh, Michael L. Wachter

All Faculty Scholarship

It has been claimed that the risk/reward dynamics of shareholder litigation have encouraged quick settlements with substantial attorneys’ fee awards but no payment to shareholders, regardless of the merits of the case. Fee-shifting charter and bylaw provisions may be too blunt a tool to control agency costs associated with excessive shareholder litigation, and are in any event now prohibited by Delaware statute. We claim, however, that active judicial supervision of public company shareholder litigation at an early stage reduces the costs of frivolous litigation to shareholders by separating meritorious from unmeritorious litigation before the full costs of discovery are incurred. …

Neuroprediction: New Technology, Old Problems, Stephen J. Morse

All Faculty Scholarship

Neuroprediction is the use of structural or functional brain or nervous system variables to make any type of prediction, including medical prognoses and behavioral forecasts, such as an indicator of future dangerous behavior. This commentary will focus on behavioral predictions, but the analysis applies to any context. The general thesis is that using neurovariables for prediction is a new technology, but that it raises no new ethical issues, at least for now. Only if neuroscience achieves the ability to “read” mental content will genuinely new ethical issues be raised, but that is not possible at present.

Making "Friends" With The #Ethics Rules: Avoiding Pitfalls In Professional Social Media Use, Cynthia Laury Dahl

All Faculty Scholarship

Lawyers’ professional use of social media is widespread and a critical component to running a successful practice. Yet some common uses of social media easily – and often innocently -- violate the professional rules of ethics. The American Bar Association recently passed amendments to the Model Rules of Professional Conduct to include topics related to social media use, but the amendments still do not address all issues. Likewise, advisory opinions of state and local bar associations and court opinions give scant and sometimes contradictory advice about when a use does or does not violate a Rule. This essay discusses four …

"Not Just A Common Criminal": The Case For Sentencing Mitigation Videos, Regina Austin

All Faculty Scholarship

Sentencing mitigation or sentencing videos are a form of visual legal advocacy that is produced on behalf of defendants for use in the sentencing phases of criminal cases (from charging to clemency). The videos are typically short (5 to 10 minutes or so) nonfiction films that explore a defendant’s background, character, and family situation with the aim of raising factual and moral issues that support the argument for a shorter or more lenient sentence. Very few examples of mitigation videos are in the public domain and available for viewing. This article provides a complete analysis of the constituent elements of …

Catalogs, Gideon Parchomovsky, Alex Stein

All Faculty Scholarship

It is a virtual axiom in the world of law that legal norms come in two prototypes: rules and standards. The accepted lore suggests that rules should be formulated to regulate recurrent and frequent behaviors, whose contours can be defined with sufficient precision. Standards, by contrast, should be employed to address complex, variegated, behaviors that require the weighing of multiple variables. Rules rely on an ex ante perspective and are therefore considered the domain of the legislator; standards embody a preference for ex post, ad-hoc, analysis and are therefore considered the domain of courts. The rules/standards dichotomy has become a …

Vertical Restraints, Dealers With Power, And Antitrust Policy, Herbert J. Hovenkamp

All Faculty Scholarship

The Supreme Court’s Leegin decision has now brought the rule of reason to all purely vertical intrabrand distribution restraints. But the rule of reason does not mean per se legality and occasions for anticompetitive vertically imposed restraints may still arise. Of all those that have been suggested the most plausible are vertical restraints imposed at the behest of a powerful dealer or group (cartel) of dealers.

Although a vertical distribution restraint resembles a dealer cartel in that both limit intraband competition, a manufacturer restraining the distribution of its product shuns the excess dealer profits a dealer cartel would seek. Accordingly, …

The Distortionary Effect Of Evidence On Primary Behavior, Gideon Parchomovsky, Alex Stein

All Faculty Scholarship

In this Essay, we analyze how evidentiary concerns dominate actors’ behavior. Our findings offer an important refinement to the conventional wisdom in law and economics literature, which assumes that legal rules can always be fashioned to achieve socially optimal outcomes. We show that evidentiary motivations will often lead actors to engage in socially suboptimal behavior when doing so is likely to increase their likelihood of prevailing in court. Because adjudicators must base decisions on observable and verifiable information—or, in short, evidence—rational actors will always strive to generate evidence that can later be presented in court and increase their chances of …

Documentation, Documentary, And The Law: What Should Be Made Of Victim Impact Videos?, Regina Austin

All Faculty Scholarship

Since the Supreme Court sanctioned the introduction of victim impact evidence in the sentencing phase of capital cases in Payne v. Tennessee, 501 U.S. 808 (1991), there have been a number of reported decisions in which that evidence has taken the form of videos composed of home-produced still photographs and moving images of the victim. Most of these videos were first shown at funerals or memorial services and contain music appropriate for such occasions. This article considers the probative value of victim impact videos and responds to the call of Justice John Paul Stevens, made in a statement regarding the …

Does Anyone Get Stopped At The Gate? An Empirical Assessment Of The Daubert Trilogy In The States, Eric Helland, Jonathan Klick

All Faculty Scholarship

The Supreme Court’s trilogy of evidence cases, Daubert, Joiner, and Kumho Tire appear to mark a significant departure in the way scientific and expert evidence is handled in federal court. By focusing on the underlying methods used to generate the experts’ conclusions, Daubert has the potential to impose a more rigorous standard on experts. Given this potential, some individuals have called for states to adopt the Daubert standards to purge “junk science” from state courts. However, there is relatively little empirical support for the notion that Daubert affects the quality of expert evidence. Using a large dataset of state court …
