Debunked, Discredited, But Still Defended: Why Prosecutors Resist Challenges To Bad Science And Some Suggestions For Crafting Remedies For Wrongful Conviction Based On Changed Science, Aviva A. Orenstein
Articles by Maurer Faculty
Flawed science has significantly contributed to wrongful convictions. Courts struggle with how to address such convictions when the mistaken science (such as bogus expert claims about the differences between accidental fires and intentionally set ones) significantly affected the guilty verdict but there is no DNA evidence to directly exonerate the accused. My short piece explores why prosecutors often defend bad science. Mistakes in science tend to serve the prosecution, but there are other more subtle factors that explain prosecutors’ reluctance to address flawed forensic testimony. Such reluctance may arise from fondness for the status quo and a resistance to subverting …
Williams V. Illinois And The Confrontation Clause: Does Testimony By A Surrogate Witness Violate The Confrontation Clause?, Paul F. Rothstein, Ronald J. Coleman
Williams V. Illinois And The Confrontation Clause: Does Testimony By A Surrogate Witness Violate The Confrontation Clause?, Paul F. Rothstein, Ronald J. Coleman
Georgetown Law Faculty Publications and Other Works
This article comprises a four-part debate between Paul Rothstein, Professor of Law at Georgetown Law Center, and Ronald J. Coleman, who works in the litigation practice group at Cleary Gottlieb Steen & Hamilton LLP, on Williams v. Illinois, a Supreme Court case that involves the Confrontation Clause, which entitles a criminal defendant to confront an accusing witness in court. The issue at hand is whether said clause is infringed when a report not introduced into evidence at trial is used by an expert to testify about the results of testing that has been conducted by a non-testifying third party. …
The Witness Who Saw, He Left Little Doubt: A Comparative Consideration Of Expert Testimony In Mental Disability Law Cases, Michael L. Perlin, Astrid Birgden, Kris Gledhill
The Witness Who Saw, He Left Little Doubt: A Comparative Consideration Of Expert Testimony In Mental Disability Law Cases, Michael L. Perlin, Astrid Birgden, Kris Gledhill
Articles & Chapters
The question of how courts assess expert evidence - especially when mental disability is an issue - raises the corollary question of whether courts adequately evaluate the content of the expert testimony or whether judicial decision making may be influenced by teleology (‘cherry picking’ evidence), pretextuality (accepting experts who distort evidence to achieve socially desirable aims), and/or sanism (allowing prejudicial and stereotyped evidence). Such threats occur despite professional standards in forensic psychology and other mental health disciplines that require ethical expert testimony. The result is expert testimony that, in many instances, is at best incompetent and at worst biased. The …
Experts, Mental States, And Acts, Christopher Slobogin
Experts, Mental States, And Acts, Christopher Slobogin
Vanderbilt Law School Faculty Publications
This article, written for a symposium on "Guilt v. Guiltiness: Are the Right Rules for Trying Factual Innocence Inevitably the Wrong Rules for Trying Culpability?," argues that the definition of expertise in the criminal justice system, derived in the federal courts and in most states from Daubert v. Merrell Dow Pharmaceuticals Co., should vary depending on whether the issue involved is past mental state or past conduct. While expert psychological testimony about past acts ought to be based on scientifically verifiable assertions, expert psychological testimony about subjective mental states relevant to criminal responsibility need not meet the same threshold. This …
Statistics In The Jury Box: How Jurors Respond To Mitochondrial Dna Match Probabilities, David H. Kaye, Valerie P. Hans, B. Michael Dann, Erin J. Farley, Stephanie Albertson
Statistics In The Jury Box: How Jurors Respond To Mitochondrial Dna Match Probabilities, David H. Kaye, Valerie P. Hans, B. Michael Dann, Erin J. Farley, Stephanie Albertson
Cornell Law Faculty Publications
This article describes parts of an unusually realistic experiment on the comprehension of expert testimony on mitochondrial DNA (mtDNA) sequencing in a criminal trial for robbery. Specifically, we examine how jurors who responded to summonses for jury duty evaluated portions of videotaped testimony involving probabilities and statistics. Although some jurors showed susceptibility to classic fallacies in interpreting conditional probabilities, the jurors as a whole were not overwhelmed by a 99.98% exclusion probability that the prosecution presented. Cognitive errors favoring the defense were more prevalent than ones favoring the prosecution. These findings lend scant support to the legal argument that mtDNA …
The Structure Of Expertise In Criminal Cases, Christopher Slobogin
The Structure Of Expertise In Criminal Cases, Christopher Slobogin
Vanderbilt Law School Faculty Publications
This essay, part of a two-issue symposium on the implications of Daubert v. Merrell Dow Pharmaceuticals and its progeny, is built around three propositions about expert testimony and criminal cases. First, the "Daubert trilogy's" focus on verifiability as the threshold for expert testimony pushes the criminal justice system away from the notion that knowledge is socially constructed and toward a positivist epistemology that assumes we can know things objectively. Second, in the long run, that development will be good for prosecutors and bad for criminal defendants, given the different types of expertise on which they rely. Third, the consequence of …
Prosecutorial Use Of Expert Testimony In Domestic Violence Cases: From Recantation To Refusal To Testify, Audrey Rogers
Prosecutorial Use Of Expert Testimony In Domestic Violence Cases: From Recantation To Refusal To Testify, Audrey Rogers
Elisabeth Haub School of Law Faculty Publications
This article discusses the use of expert testimony in prosecuting those charged with domestic abuse. Part I provides a background on the need and nature of expert testimony in domestic violence cases and the requirements for the admission of such expert testimony. It traces the development of the role of expert testimony in domestic violence cases from its initial exclusive use as a defense tool to support self-defense claims to its present use by prosecutors to explain a complainant's recantation or other puzzling behavior. Part II discusses the appellate cases that have addressed the admissibility and scope of expert testimony …

A Look At Florida's Proposed Code Of Evidence, Charles W. Ehrhardt
A Look At Florida's Proposed Code Of Evidence, Charles W. Ehrhardt
Scholarly Publications
The law of evidence had been codified in three states, California, New Jersey and Kansas, prior to the United States Supreme Court's promulgation of the Proposed Federal Rules of Evidence. The submission of the rules to the Congress, and their approval, as amended, by the House of Representatives served as the catalyst for renewed interest in evidence codification. Three states have recently adopted comprehensive Rules of Evidence that closely parallel the Proposed Federal Rules, and at least four other states, including Florida, have drafted or are actively considering the adoption of such a codification. During the 1974 session of the …
