Error Costs, Legal Standards Of Proof And Statistical Significance, Michelle Burtis, Jonah B. Gelbach, Bruce H. Kobayashi

All Faculty Scholarship

The relationship between legal standards of proof and thresholds of statistical significance is a well-known and studied phenomena in the academic literature. Moreover, the distinction between the two has been recognized in law. For example, in Matrix v. Siracusano, the Court unanimously rejected the petitioner’s argument that the issue of materiality in a securities class action can be defined by the presence or absence of a statistically significant effect. However, in other contexts, thresholds based on fixed significance levels imported from academic settings continue to be used as a legal standard of proof. Our positive analysis demonstrates how a …

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 …

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 …

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 …
