Take The Motherless Children Off The Street: Fetal Alcohol Syndrome And The Criminal Justice System, Michael L. Perlin, Heather Ellis Cucolo Apr 2023

Take The Motherless Children Off The Street: Fetal Alcohol Syndrome And The Criminal Justice System, Michael L. Perlin, Heather Ellis Cucolo

Articles & Chapters

Remarkably, there has been minimal academic legal literature about the interplay between fetal alcohol syndrome disorder (FASD) and critical aspects of many criminal trials, including issues related to the role of experts, quality of counsel, competency to stand trial, the insanity defense, and sentencing and the death penalty. Nor has there been any literature about the interplay between FASD-related issues and the legal school of thought known as therapeutic jurisprudence.

In this article, the co-authors will first define fetal alcohol syndrome and explain its significance to the criminal justice system. We will then look at the specific role of experts …


"Insanity Is Smashing Up Against My Soul": The Fifth Circuit And Competency To Be Executed Cases After Panetti V. Quarterman, Michael L. Perlin, Talia Roitberg Harmon Apr 2022

"Insanity Is Smashing Up Against My Soul": The Fifth Circuit And Competency To Be Executed Cases After Panetti V. Quarterman, Michael L. Perlin, Talia Roitberg Harmon

Articles & Chapters

One of the open secrets of death penalty law and policy is the astonishingly high percentage of individuals on death row with serious mental disabilities. This is well known to lawyers who represent this cohort (and presumably, equally well known to the district attorneys who nevertheless prosecute them and the judges who try and sentence them), but is not generally discussed in the press nor, certainly, in political discourse. In the aggregate, this is far beneath society’s radar.

It is now over 14 years since the US Supreme Court decided a case that clarified the underlying issues. In Panetti v. …


Authoring Prior Art, Joseph P. Fishman, Kristelia A. García Jan 2022

Authoring Prior Art, Joseph P. Fishman, Kristelia A. García

Publications

Patent law and copyright law are widely understood to diverge in how they approach prior art, the universe of information that already existed before a particular innovation’s development. For patents, prior art is paramount. An invention can’t be patented unless it is both novel and nonobvious when viewed against the backdrop of all the earlier inventions that paved the way. But for copyrights, prior art is supposed to be virtually irrelevant. Black-letter copyright doctrine doesn’t care if a creative work happens to resemble its predecessors, only that it isn’t actually copied from them. In principle, then, outside of the narrow …

The Disappointing History Of Science In The Courtroom: Frye, Daubert, And The Ongoing Crisis Of “Junk Science” In Criminal Trials, Jim Hilbert Jan 2019

The Disappointing History Of Science In The Courtroom: Frye, Daubert, And The Ongoing Crisis Of “Junk Science” In Criminal Trials, Jim Hilbert

Faculty Scholarship

Twenty-five years ago, the Supreme Court decided one of the most important cases concerning the use of science in courtrooms. In Daubert v. Merrell Dow Pharmaceuticals , the Court addressed widespread concerns that courts were admitting unreliable scientific evidence. In addition, lower courts lacked clarity on the status of the previous landmark case for courtroom science, Frye v. United States. In the years leading up to the Daubert decision, policy-makers and legal observers sounded the alarm about the rise in the use of "junk science" by so-called expert witnesses. Some critics went so far as to suggest that American businesses …


Neuroscience In Forensic Contexts: Ethical Concerns, Stephen J. Morse Feb 2017

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 …

Frazier V. Drake, 131 Nev. Adv. Op. 64 (Sep. 3, 2015), Adrian Viesca

Nevada Supreme Court Summaries

The Court of Appeals determined that (1) when three of the good-faith Beattie factors weigh in favor of the party that rejected the offer of judgment, the reasonableness of the fees requested by the offeror becomes irrelevant, and cannot, by itself, support a decision to award attorney fees to the offeror and (2) expert witness fees in excess of $1,500 now have factors to take into consideration in awarding such fees.

An Economic Analysis Of Fact Witness Payment, Eugene Kontorovich, Ezra Friedman Jan 2011

An Economic Analysis Of Fact Witness Payment, Eugene Kontorovich, Ezra Friedman

Faculty Working Papers

In this paper we discuss the disparate treatment of perceptual (''fact'') witnesses and expert witnesses in the legal system. We highlight the distinction between the perceptual act of witnessing and the act of testifying, and argue that although there might be good reasons to regulate payments to fact witnesses, the customary prohibition on paying them for their services is not justified by reference to economic theory. We propose considering a court mediated system for compensating fact witnesses so as to encourage witnessing of legally important events.We construct a simple model of witness incentives, and simulate the effects of several possible …


Blind Expertise, Christopher Robertson Jan 2010

Blind Expertise, Christopher Robertson

Faculty Scholarship

The United States spends many billions of dollars on its system of civil litigation, and expert witnesses appear in a huge portion of cases. Yet litigants select and retain expert witnesses in ways that create the appearance of biased hired guns on both sides of every case, thereby depriving factfinders of a clear view of the facts. As a result, factfinders too often arrive at the wrong conclusions, thus undermining the deterrence and compensation functions of litigation. Court-appointment of experts has been widely proposed as a solution, yet it raises legitimate concerns about accuracy and has failed to gain traction …

Prosecutors, Ethics, And Expert Witnesses, Paul C. Giannelli, Kevin C. Mcmunigal Jan 2007

Prosecutors, Ethics, And Expert Witnesses, Paul C. Giannelli, Kevin C. Mcmunigal

Faculty Publications

Commentators who have examined the DNA exonerations have noted the disturbing role that prosecutors have played in these wrongful convictions. Another significant contributor to these miscarriages of justice is the misuse of expert testimony, a third of the cases according to some sources. This Article examines the intersection of these two factors - the prosecutor's role in using and presenting expert testimony.

Prosecutorial misconduct may occur during most stages of a trial, beginning with the selection of witnesses, including the improper "shopping" for experts. Additional abuses occur when prosecutors fail to abide by rules governing the pretrial disclosure of scientific …


Gatekeeping After Gilbert: How Lawyers Should Address The Court's New Emphasis, Brian Benner, Ronald L. Carlson Mar 2006

Gatekeeping After Gilbert: How Lawyers Should Address The Court's New Emphasis, Brian Benner, Ronald L. Carlson

Popular Media

In the world of modern trials, expert witnesses are the coin of the realm. Lawyers know that most of the time, experts are case-breakers. Their demeanor, knowledge, and presentation ability are key qualities. Accordingly, their persuasive effect on modern lay jurors makes it incumbent on judges to ensure that an expert's opinions are appropriately directed. That means not allowing an economist to testify about the medical dynamics of bone disease, for example.


Reconsidering The Medical Expert Witness System, Yunwei Jiang Jan 2006

Reconsidering The Medical Expert Witness System, Yunwei Jiang

LLM Theses and Essays

The expert witness is indispensable in a medical malpractice case. However, there are three main defects in the currently existing expert witness system. One is incompetence of expert witnesses. Another is professional negligence of expert witnesses. The other is dishonesty of expert witnesses. To make the expert witness system more efficient, this article examines currently existing rules and offers some proposals regarding the three issues. For the first one, the suggestion of this article is to rely on the standards of expert qualification and admitting expert testimony. For the second one, this article distinguishes expert witnesses from lay witnesses, and …


Emergency Contraception, Abortion And Evidence-Based Law, Rebecca Cook, Bernard Dickens, Joanna Erdman Jan 2006

Emergency Contraception, Abortion And Evidence-Based Law, Rebecca Cook, Bernard Dickens, Joanna Erdman

Articles, Book Chapters, & Popular Press

Courts and legal tribunals increasingly decline to serve as religious or moral guardians, and require social evidence to support litigants' claims. Recent cases on emergency contraception and abortion are examined to show how judicial interpretations can take account of evidence of the impact that different understandings of the law will have for how ordinary people can plan their lives and reproductive choices. In an emergency contraception case, an interpretation was rejected that would have criminalized choices that millions of decent, law-abiding physicians, pharmacists and women routinely make. In an abortion case, three judges unanimously rejected a government ministry's defence of …


Expert Testimony In Capital Sentencing: Juror Responses, John H. Montgomery, J. Richard Ciccone, Stephen P. Garvey, Theodore Eisenberg Jan 2005

Expert Testimony In Capital Sentencing: Juror Responses, John H. Montgomery, J. Richard Ciccone, Stephen P. Garvey, Theodore Eisenberg

Cornell Law Faculty Publications

The U.S. Supreme Court, in Furman v. Georgia (1972), held that the death penalty is constitutional only when applied on an individualized basis. The resultant changes in the laws in death penalty states fostered the involvement of psychiatric and psychologic expert witnesses at the sentencing phase of the trial, to testify on two major issues: (1) the mitigating factor of a defendant’s abnormal mental state and (2) the aggravating factor of a defendant’s potential for future violence. This study was an exploration of the responses of capital jurors to psychiatric/psychologic expert testimony during capital sentencing. The Capital Jury Project is …


Jurors' Evaluations Of Expert Testimony: Judging The Messenger And The Message, Sanja Kutnjak Ivkovic, Valerie P. Hans Apr 2003

Jurors' Evaluations Of Expert Testimony: Judging The Messenger And The Message, Sanja Kutnjak Ivkovic, Valerie P. Hans

Cornell Law Faculty Publications

Jurors are laypersons with no specific expert knowledge, yet they are routinely placed in situations in which they need to critically evaluate complex expert testimony. This paper examines jurors' reactions to experts who testify in civil trials and the factors jurors identify as important to expert credibility. Based on in-depth qualitative analysis of interviews with 55 jurors in 7 civil trials, we develop a comprehensive model of the key factors jurors incorporate into the process of evaluating expert witnesses and their testimony. Contrary to the frequent criticism that jurors primarily evaluate expert evidence in terms of its subjective characteristics, the …

A Healer Or An Executioner: The Proper Role Of A Psychiatrist In A Criminal Justice System, Gregory Dolin Jan 2003

A Healer Or An Executioner: The Proper Role Of A Psychiatrist In A Criminal Justice System, Gregory Dolin

All Faculty Scholarship

This article argues that despite the benefits of ridding the criminal justice system of some uncertainty and ignorance with respect to mental health issues, the very close involvement of psychiatrists in the criminal justice system as practiced in the United States is not only illogical and bad policy, but also unethical from the viewpoint of medical ethics. Part II of this article will lay the groundwork for the argument by discussing the history of the insanity defense, and of science's involvement with criminal justice; while Part III, will look into the association of science and the administration of justice in …


The Other Shoe Drops: Minnesota Rejects Daubert, Peter B. Knapp Jan 2002

The Other Shoe Drops: Minnesota Rejects Daubert, Peter B. Knapp

Faculty Scholarship

In 1991, the United States Supreme Court handed decided Daubert v. Merrell Dow Pharmaceuticals, Inc., rejecting the long-standing federal test for the admissibility of scientific testimony articulated in Frye v. United States. Unlike many states, however, which embraced Daubert within years--or even months--of the federal decision, Minnesota declined to make Daubert the law of the jurisdiction. In a pair of cases decided in 2000, Goeb v. Tharaldson and Sentinel Mgmt. v. Aetna Casualty & Surety, the court held that Minnesota would retain the general acceptance test. The court's rejection of Daubert can be read as an attempt to give the …

Articles

In United States v. Llera Plaza, 188 F. Supp. 2d 549 (E.D. Pa. 2002), a federal district initially limited expert opinion testimony on fingerprint identifications because the government was unable to show that such identifications were sufficiently valid and reliable under Federal Rule of Evidence 702. Then, the court withdrew the opinion. This article reproduces an exchange of notes on the initial opinion submitted by five law professors.


Experts, Carl E. Schneider Jul 2001

Experts, Carl E. Schneider

Articles

George Bernard Shaw famously said that all professions are conspiracies against the laity. Less famously, less elegantly, but at least as accurately, Andrew Abbott argued that professions are conspiracies against each other. Professions compete for authority to do work and for authority over work. The umpire in these skirmishes and sieges is the government, for the state holds the gift of monopoly and the power to regulate it. In Abbott's terms, "bioethics" is contesting medicine's power to influence the way doctors treat patients. If it follows the classic pattern, bioethics will solicit work and authority by recruiting government's power. A …


Detection Of Deception: The Case Of Handwriting Expertise, Samuel R. Gross Jan 2001

Detection Of Deception: The Case Of Handwriting Expertise, Samuel R. Gross

Articles

The basic method of handwriting identification is the same now as it was in Twelfth Night: to compare the questioned writing with other writings by the supposed writer. This can be done from memory if (like Malvolio) one is already familiar with the claimed author's handwriting, or by examining the questioned document together with known samples. It's a simple, obvious task. Any person-certainly any literate person--can have a go at it. The claim by handwriting experts, now and in the past, is equally simple: We can do it better.


Evidence Issues In Domestic Violence Civil Cases, Jane C. Murphy, Jane H. Aiken Jan 2000

Evidence Issues In Domestic Violence Civil Cases, Jane C. Murphy, Jane H. Aiken

All Faculty Scholarship

New laws and policies aimed at protecting victims of domestic violence have been adopted across the country over the last twenty years.The legal approaches taken to protect battered women and control family violence have resulted in significant changes in family law. New laws include statutes permitting civil protection or restraining orders, and laws requiring that domestic violence be considered in custody and/or visitation decisions. Both of these types of statutory reforms can provide protection to adult victims of domestic violence and their children. Evaluating a parent's fitness by considering past acts of violence to other family members results in decisions …

Substance And Form In Scientific Evidence: What Daubert Didn't Do, Samuel R. Gross

Book Chapters

On its face, Daubert v. Merrell Dow Pharmaceuticals was about as easy a case as the Supreme Court gets. The plaintiffs claimed that their birth defects were caused by the anti-nausea drug Bendectin, which their mothers had used during their gestation. In response to a motion for summary judgment by the defendant, the plaintiffs presented affidavits of eight expert witnesses who offered their opinions - based on a variety of studies - that Bendectin was indeed the culprit. The federal district court that heard the motion granted summary judgment to the defendant, and the Ninth Circuit affirmed. Both lower courts …

Should Michigan Rule Of Evidence 703 Be Revised?, Brian Benner, Ronald L. Carlson Jun 1991

Should Michigan Rule Of Evidence 703 Be Revised?, Brian Benner, Ronald L. Carlson

Popular Media

Technical witnesses regularly assist the fact-finding process in Michigan trials. Jury or bench trials in federal and state courts routinely feature the appearance of experts. Properly policed by our courts, few forms of testimony hold more promise for advancing the truth-seeking function of American litigation. The expanding presence of experts raises hard questions. Are the Michigan rules in turn with modern needs? Should the state rule controlling the basis for expert opinion be aligned with the federal pattern? If Michigan Rule of Evidence 703 could stand revision, does proper alteration require significant additions not presently contained in either state or …


The Expert In U.S. And German Patent Litigation, James Maxeiner Jan 1991

The Expert In U.S. And German Patent Litigation, James Maxeiner

All Faculty Scholarship

The expert often plays a crucial role in patent litigation in both Germany and the United States. Determination of facts and application of law to facts frequently require a technical understanding that only an expert can provide. Despite the similarity of the problem of conveying information to the decision-maker, the role of the expert in the two systems and the manner in which the problem of providing technical knowledge necessary for the decision is solved are so very different, that German jurists who transfer their German experiences and expectations over to US procedures, are in danger of experiencing great disappointment …
