Dna, Blue Bus, And Phase Changes, Edward K. Cheng, G. Alexander Nunn

Faculty Scholarship

In ‘Exploring the Proof Paradoxes’, Mike Redmayne comprehensively surveyed the puzzles at the intersection of law and statistics, the most famous of which is the Blue Bus problem, which prohibits legal actors from ascribing liability purely on the basis of probabilistic evidence. DNA evidence, however, is a longstanding exception to Blue Bus. Like Blue Bus, DNA presents probabilistic evidence of identity. Unlike Blue Bus, DNA is widely accepted as legitimate, even when it stands alone as so-called ‘naked’ statistical evidence. Observers often explain such DNA exceptionalism in two ways: either that people break down in extreme cases, or relatedly, that …

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 …

Is There Really A Sex Bureaucracy?, Suzanne B. Goldberg

Faculty Scholarship

This essay identifies several features of the higher-education context that can enrich The Sex Bureaucracy‘s account of why colleges and universities have adopted new policies and trainings to address sexual assault on their campuses. These features include: 1) schools’ preexisting systems for addressing student conduct; 2) the shared interest of schools in reducing impediments to education, including nonconsensual sexual contact; and 3) the pedagogical challenges of developing trainings that are engaging and effective. Taking these three factors into account, we can see that while federal Title IX intervention has had a profound effect, it is also important not to …

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 …

Dna And Distrust, Kerry Abrams, Brandon L. Garrett

Faculty Scholarship

Over the past three decades, government regulation and funding of DNA testing has reshaped the use of genetic evidence across various fields, including criminal law, family law, and employment law. Courts have struggled with questions of when and whether to treat genetic evidence as implicating individual rights, policy trade-offs, or federalism problems. We identify two modes of genetic testing: identification testing, used to establish a person’s identity, and predictive testing, which seeks to predict outcomes for a person. Judges and lawmakers have often drawn a bright line at predictive testing, while allowing uninhibited identity testing. The U.S. Supreme Court in …

The Novel New Jersey Eyewitness Instruction Induces Skepticism But Not Sensitivity, Athan Papailiou, David Yokum, Christopher Robertson

Faculty Scholarship

In recent decades, social scientists have shown that the reliability of eyewitness identifications is much worse than laypersons tend to believe. Although courts have only recently begun to react to this evidence, the New Jersey judiciary has reformed its jury instructions to notify jurors about the frailties of human memory, the potential for lineup administrators to nudge witnesses towards suspects that they police have already identified, and the advantages of alternative lineup procedures, including blinding of the administrator. This experiment tested the efficacy of New Jersey’s jury instruction. In a 2×2 between-subjects design, mock jurors (N = 335) watched a …

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 …

Imaging Brains, Changing Minds: How Pain Neuroimaging Can Inform The Law, Amanda C. Pustilnik

Faculty Scholarship

What would the law do differently if it could see into the black box of the mind? One of the most valuable things it might do is reform the ways it deals with pain. Pain is ubiquitous in law, from tort to torture, from ERISA to expert evidence. Yet legal doctrines grapple with pain poorly, embodying concepts that are generations out of date and that cast suspicion on pain sufferers as having a problem that is “all in their heads.”

Now, brain-imaging technologies are allowing scientists to see the brain in pain—and to reconceive of many types of pain as …

Cell Phones, Brain Cancer, And Scientific Outliers In Murray V. Motorola, David H. Kaye

Faculty Scholarship

Pending before the District of Columbia's highest court in a case asking whether cell phones can cause cancer is whether to replace the jurisdiction's venerable Frye standard for reviewing the admissibility of scientific evidence with the approach adopted by the U.S. Supreme Court in Daubert v. Merrell Dow. The author analyzes one aspect of the two evidentiary standards that leads him to question the trial judge's suggestion in Murray v. Motorola that adopting the Daubert perspective would allow greater leeway in excluding the plaintiff's evidence.

Wrongful Convictions And Upstream Reform In The Criminal Justice System, Kate Kruse

Faculty Scholarship

This Article explores the viability of upstream criminal justice reforms within the context of an adversary and procedural system of criminal justice, focusing on reforms in eyewitness identification procedures. Mistaken eyewitness identification evidence is often cited as the leading cause of wrongful convictions in the United States. Eyewitness identification reforms have also been the most developed upstream efforts to grow out of the innocence movement. The success and limitation of upstream reform in eyewitness identification shed light on the efficacy of upstream criminal justice system reform more generally, as well as in areas that are less developed, such as the …

Ultracrepidarianism In Forensic Science: The Hair Evidence Debacle, David H. Kaye

Faculty Scholarship

For over 130 years, scientific sleuths have been inspecting hairs under microscopes. Late in 2012, the FBI, the Innocence Project, and the National Association of Criminal Defense Lawyers joined forces to review thousands of microscopic hair comparisons performed by FBI examiners over several of those decades. The results have been astounding. Based on the first few hundred cases in which hairs were said to match, it appears that examiners “exceeded the limits of science” in over 90% of their reports or testimony. The disclosure of this statistic has led to charges that the FBI “faked an entire field of forensic …

Electronically Stored Information And The Ancient Documents Exception To The Hearsay Rule: Fix It Before People Find Out About It, Daniel J. Capra

Faculty Scholarship

The first website on the Internet was posted in 1991. While there is not much factual content on the earliest websites, it did not take long for factual assertions—easily retrievable today—to flood the Internet. Now, over one hundred billion emails are sent, and ten million static web pages are added to the Internet every day. In 2006 alone, the world produced electronic information that was equal to three million times the amount of information stored in every book ever written. The earliest innovations in electronic communication are now over twenty years old—meaning that the factual assertions made by way of …

The New Stock Market: Sense And Nonsense, Merritt B. Fox, Lawrence R. Glosten, Gabriel Rauterberg

Faculty Scholarship

How stocks are traded in the United States has been totally transformed. Gone are the dealers on NASDAQ and the specialists at the NYSE. Instead, a company’s stock can now be traded on up to sixty competing venues where a computer matches incoming orders. High-frequency traders (HFTs) post the majority of quotes and are the preponderant source of liquidity in the new market.

Many practices associated with the new stock market are highly controversial, as illustrated by the public furor following the publication of Michael Lewis’s book Flash Boys. Critics say that HFTs use their speed in discovering changes in …

Decision-Making In The Dark: How Pre-Trial Errors Change The Narrative In Criminal Jury Trials, Kara Mackillop, Neil Vidmar

Faculty Scholarship

Over the past decade and a half, a great deal of attention has rightfully been given to the issue of wrongful convictions. In 2003, Jim Dwyer, Peter Neufeld and Barry Scheck published Actual Innocence, an eyeopening treatise on the reality of wrongful convictions in the United States. In the years since, more than 1400 innocent persons have been exonerated, and a very diverse research community of attorneys, academics, social scientists, and activists has developed in response to the realization offlaws in our criminal justice system. In 2012, Brandon Garrett's Convicting the Innocent quantitatively evaluated the first 250 DNA exonerations and …

Painful Disparities, Painful Realities, Amanda C. Pustilnik

Faculty Scholarship

Legal doctrines and decisional norms treat chronic claims pain differently than other kinds of disability or damages claims because of bias and confusion about whether chronic pain is real. This is law’s painful disparity. Now, breakthrough neuroimaging can make pain visible, shedding light on these mysterious ills. Neuroimaging shows these conditions are, as sufferers have known all along, painfully real. This Article is about where law ought to change because of innovations in structural and functional imaging of the brain in pain. It describes cutting-edge scientific developments and the impact they should make on evidence law and disability law, and, …

A Primer On The Use Of Dangerous Trial Exhibits, Robert M. Jarvis

Faculty Scholarship

It sometimes is necessary at trial to introduce a dangerous exhibit-such as a bomb, gun, or knife-to bolster a client's story, discredit an opposing witness, or give the jury a clearer picture of the underlying events. Doing so, however, requires care and planning. Not only do many courts have specific rules regarding how such exhibits are to be noticed, handled, and displayed, but there are also numerous practical and tactical considerations that must be weighed. In this Article, the author presents the first comprehensive discussion regarding dangerous trial exhibits and offers suggestions for their successful use.
