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

All 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 Prods., Inc. v. McDonald’s Corp., ruled that expert testimony was inadmissible to determine whether Mayor McCheese and the merry band of McDonaldland 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 …

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 …

The Triangle Of Law And The Role Of Evidence In Class Action Litigation, Jonah B. Gelbach

All Faculty Scholarship

In Tyson Foods v. Bouaphakeo, a "donning and doffing" case brought under Iowa state law incorporating the Fair Labor Standards Act's overtime pay provisions, the petitioners asked the Supreme Court to reject the use of statistical evidence in Rule 23(b)(3) class certification. To its great credit, the Court refused. In its majority opinion, the Court cited both the Federal Rules of Evidence and federal common law interpreting the FLSA. In this paper, I take a moderately deep dive into the facts of the case, and the three opinions penned by Justice Kennedy (for the Court), Chief Justice Roberts (in …

Just And Speedy: On Civil Discovery Sanctions For Luddite Lawyers, Michael Thomas Murphy

All Faculty Scholarship

This article presents a theoretical model by which a judge could impose civil sanctions on an attorney - relying in part on Rule 1 of the Federal Rules of Civil Procedure - for that attorney’s failure to utilize time- and expense-saving technology.

Rule 1 now charges all participants in the legal system to ensure the “just, speedy and inexpensive” resolution of disputes. In today’s litigation environment, a lawyer managing a case in discovery needs robust technological competence to meet that charge. However, the legal industry is slow to adopt technology, favoring “tried and true” methods over efficiency. This conflict is …

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. …

Proportionality And The Social Benefits Of Discovery: Out Of Sight And Out Of Mind?, Stephen B. Burbank

All Faculty Scholarship

In this short essay, based on remarks delivered at the 2015 meeting of the AALS Section of Litigation, I use a recent paper by Gelbach and Kobayashi to highlight the risk that, in assessing the proportionality of proposed discovery under the 2015 amendments to Rule 26 of the Federal Rules of Civil Procedure, federal judges will privilege costs over benefits, and private over public interests. The risk arises from the temptation to focus on (1) the interests of those who are present to the detriment of the interests of those who are absent (“the availability heuristic”), and (2) variables that …

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.

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 …

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 …
