The Emotional Juror, Todd E. Pettys

Todd E. Pettys

Addressing the dichotomy often drawn between emotions and rationality, I argue that, while emotions sometimes exert undesirable influences in the courtroom, there are a variety of ways in which emotions aid rational decision-making by jurors.

A History Of Representations Of Justice: Coincident Preoccupations Of Law And Film, Jessica M. Silbey

Jessica Silbey

The American trial and the art of cinema share certain epistemological tendencies. Both stake claims to an authoritative form of knowledge based on the indubitable quality of observable phenomena. Both are preoccupied (sometimes to the point of self-defeat) with sustaining the authority that underlies the knowledge produced by visual perception. The American trial and art of cinema also increasingly share cultural space. Although the trial film (otherwise known as the courtroom drama) is as old as the medium of film the recent spate of popular trial films, be they fictional such as Runaway Jury or documentary such as Capturing the …

The Fax As Valid Evidence In Argentine Law, Felipe Eduardo Zabalza, Leandro Javier Caputo

Felipe Eduardo Zabalza

Under Argentine law, the facsimile transmission (fax) is not acceptable under certain circumstances. A recent decision in “Flowtex France S.R.L. v. Flowtex Servicios Urbanos S.A.”, handed down by the National Court of Appeals on Commercial Matters, Chamber A, stated that “a simple photocopy of a fax is not enough proof of the existence of a loan contract”.

As background to this matter, the Argentine court ruled in an international case regarding a loan made by a French company to an Argentine company, with particular consideration of the facsimile as valid evidence in commercial proceedings.

Science In The Jury Box: Jurors' Views And Understanding Of Mitochondrial Dna Evidence, Valerie P. Hans, David H. Kaye, 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 …

Crawford’S Aftershock: Aligning The Regulation Of Non-Testimonial Hearsay With The History And Purposes Of The Confrontation Clause, Fred O. Smith

Fred O. Smith Jr.

This Article explores what the purposes, history and text of the Confrontation Clause have to say about the admission of non-testimonial hearsay statements. Part I examines historical sources such as the common law near the Founding, as well as the text of the clause, and concludes that non-testimonial hearsay was one of the ills that the Confrontation Clause was designed to protect. Part I additionally proposes a two-tiered approach to interpreting the Confrontation Clause, in which testimonial statements receive the most vigorous form of constitutional scrutiny, but non-testimonial statements receive meaningful scrutiny as well. The United States Constitution is no …

Towards A Scientific Standard For The Admissibility And Evaluation Of Psychiatric Evidence In War Crimes Prosecutions, Matthew J. Madalo

Matthew J Madalo

"Towards a Standard for the Admissibility and Evaluation of Psychiatric Evidence in War Crimes Prosecutions" explores the nature and use of psychiatric/psychological defenses and evidence in war crimes prosecutions. Part I of the article focuses on the differing goals and overlapping concerns between psychiatry and the law. In the international criminal legal context, the discussion will center on the types of psychiatric evidence and defenses that have been used or are likely to be used in war crimes prosecutions. Part II analyzes the applicable ICTY, ICR and ICC Statutes, Rules of Procedure and Evidence, and relevant United States common law …

Who Knew? The Admissibility Of Subsequent Remedial Measures When Defendants Are Without Knowledge Of The Injuries, Ryan G. Vacca

Akron Law Faculty Publications

Federal Rule of Evidence 407 and equivalent state court rules prohibit the introduction of subsequent remedial measures for the purpose of demonstrating negligence, culpable conduct, or product defect. The rule breaks down, however, in application and purpose, when a defendant undertakes a new safety measure after the plaintiff's injury but before the defendant had knowledge of the loss. Such a situation is not uncommon. Would-be defendants frequently improve their products and product safety, whether in response to injuries incurred by other users, business pressures, or simply advances in the state of the art and scientific knowledge. Toxic exposure cases, where …

Judging Genes: Implications Of The Second Generation Of Genetic Tests In The Courtroom, Diane E. Hoffmann, Karen H. Rothenberg

Faculty Scholarship

The use of DNA tests for identification has revolutionized court proceedings in criminal and paternity cases. Now, requests by litigants to admit or compel a second generation of genetic tests – tests to confirm or predict genetic diseases and conditions – threaten to affect judicial decision-making in many more contexts. Unlike DNA tests for identification, these second generation tests may provide highly personal health and behavioral information about individuals and their relatives and will pose new challenges for trial court judges. This article reports on an original empirical study of how judges analyze these requests and uses the study results …

Inadmissible, Eh?, Jocelyn Downie, Ronalda Murphy

Articles, Book Chapters, & Popular Press

In this commentary, we respond to Stacey Tovino's invitation to reflect further on specific legal issues she raises in relation to functional magnetic resonance imaging (fMRI) and the law (Tovino 2007). Specifically, we take up the issue of evidence law. We do this from a Canadian perspective because, unlike in the United States, this topic has not "been debated for almost 10 years" here (Tovino 2007, 44).

Making The Sale On Contingent Valuation, Sameer H. Doshi

Sameer H Doshi

Scholarship and jurisprudence have not seriously considered the question of whether the contingent valuation (CV) technique of monetizing preferences for non-tradeable public goods is consistent with the Daubert standards for scientific evidence. The greatest difficulty is in establishing that CV is testable and has measurable error rates; this problem is consonant with criticisms that economists have leveled at the CV method more generally. Additionally, the “state of the art” of contingent valuation practice has recommended the use of the willingness-to-pay question format for CV, rather than willingness-to-accept. This is misplaced in many cases, particularly in calculating damages in environmental tort …

Confronting The “Ongoing Emergency”: A Pragmatic Approach To Hearsay Evidence In The Context Of The Sixth Amendment, Ellen Liang Yee

ellen yee

The Supreme Court’s path breaking decision in Crawford v. Washington, 541 U.S 36 (2004), held that admission of an extrajudicial testimonial statement by an unavailable declarant-witness violates the Confrontation Clause unless the defendant has an opportunity to cross-examine the declarant. Unfortunately, the determination of admissibility for the trial court judge has not been simplified after Crawford. The role of the trial court judge has now shifted from determining the reliability of the hearsay evidence (as was required before Crawford) to a determination of the testimonial nature of the declarant’s statement. However, with some small exceptions, the Court in Crawford explicitly …

To Speak Or Not To Speak? Navigating The Treacherous Waters Of Parallel Investigations Following The Amendment Of Federal Rule Of Evidence 408, Mikah K. Story Thompson

Mikah K. Story Thompson

This article is the first to explore the true impact of the recently amended Fed. R. Evid. 408 on parallel proceedings. Parallel proceedings exist where the government conducts both a civil and criminal investigation against a defendant for single instance of alleged misconduct. Prior to the rule’s amendment, a defendant facing parallel proceedings had the ability to negotiate settlement of the civil suit without fear that any incriminating statements made during settlement talks would later re-surface in the criminal case. However, the amendment to Rule 408 singles out defendants facing parallel proceedings by stating that the government may use any …

Should Statements Made By Patients During Psychotherapy Fall Within The Medical Treatment Hearsay Exception? An Interdisciplinary Critique, Philip K. Hamilton

Philip K. Hamilton

This article challenges the prevailing view of courts that statements made to a mental health clinician are the functional equivalent of statements made for the purpose of any other kind of treatment and should therefore be admitted under the hearsay exception for statements made for the purposes of medical diagnosis or treatment. The article takes the position that, because of the nature of psychotherapy, patient statements to therapists are not sufficiently reliable to be included in the hearsay exception.

This use of the “medical treatment exception,” which began with statements of child victims in abuse cases, has been extended to …

Procedural Path Dependence: Discrimination And The Civil-Criminal Divide, Julie C. Suk

Julie C Suk

Procedural path dependence occurs when the particular features of the procedural system which has been charged with enforcing a given legal norm determine the substantive path of that legal norm. This article shows how the limits of employment discrimination law in two different national contexts can be explained by procedural dynamics. In France, as in several European countries, employment discrimination law is enforced predominantly in criminal proceedings. French criminal procedure enables the discovery of information necessary to proving the facts of discrimination, whereas the limited nature of French civil procedure makes it impossible for such information to be revealed. As …

Toward A Unified Theory Of Testimonial Evidence Under The Fifth And Sixth Amendments, Michael J.Z. Mannheimer

Michael J.Z. Mannheimer

There is an obvious parallel between the language of the Self-Incrimination Clause and that of the Confrontation Clause: the former forbids the government from forcing a criminal suspect to become a “witness against himself,” while the latter requires the government to allow a criminal defendant to confront the “witnesses against him.” The irresistible inference is that the word “witness” means the same thing in both Clauses. And, indeed, the Supreme Court has hinged the question of whether someone is a "witness" in both contexts on whether he or she has given "testimonial" evidence. Yet, at least at first blush, the …

Credibility: A Fair Subject For Expert Testimony?, Anne Poulin

Working Paper Series

This article explores the ways in which experts can assist the jury to assess the credibility of other witnesses and suggests analytical approaches to such expert testimony. The article argues that the courts should be more receptive to expert testimony bearing on witness credibility and engage in a more nuanced consideration of the role played by proffered expert testimony and how the role of the evidence affects its admissibility. Doing so should lead the courts to embrace the promise of the modern rules of evidence and permit experts to assist juries as they assess credibility.

If The Glove Don’T Fit, Try Newer Gloves: The Unplanned Obsolescence Of The Substantial Similarity Standard For Experimental Evidence, Jonathan M. Hoffman

Jonathan M Hoffman

In the context of a recent Fifth Circuit decision, this article reviews the law concerning the admissibility of “experimental” and demonstrative evidence. The standards used to determine the admissibility of both categories of evidence predate the Federal Rules of Evidence. These standards for admission of such evidence are obsolete and at odds with the Federal Rules. The issue is particularly important in the wake of the Kumho Tire decision and the 2000 amendments to Federal Rule of Evidence 702, as engineers and other technical experts are increasingly called upon to test their hypotheses, even as the courts’ continued use of …

Evidentiary Value Of Expert Opinion Under Indian Evidence Act, Krishna Kumari Areti

Krishna Kumari Areti prof

Law of evidence allows a person –who is a witness to state the facts related to either to a fact in issue or to relevant fact, but not his inference. It applies to both criminal law and civil law. The opinion of any person other than the judge by whom the fact has to be decided as to the existence of the facts in issue or relevant facts are as a rule, irrelevant to the decision of the cases to which they relate for the most obvious reasons- for this would invest the person whose opinion was proved with the …

Search And Seizure On Steroids: United States V. Comprehensive Drug Testing And Its Consequences For Private Information Stored On Commercial Electronic Databases, Aaron S. Lowenstein

Aaron S Lowenstein

This article critiques the Ninth Circuit’s recent decision in United States v. Comprehensive Drug Testing. This case received some attention because it stems from the investigation into the use of steroids in Major League Baseball. It should have received much more attention, however, because of its troubling expansion of the government’s authority to access our private digital information without a warrant.

Executing a search warrant for information stored on a computer database poses special problems. Because targets of government investigations can easily conceal incriminating digital evidence, investigators often must search an entire computer hard drive in order to effectively execute …

Miranda Is Not Enough: A New Justification For Demanding "Strong Corroboration" To A Confession, Boaz Sangero

Prof. Boaz Sangero

Following research conducted in recent years—some of it regarding evidence obtained through DNA testing—no doubt remains that, in reality, innocent persons are convicted of crimes and that, in a significant number of these cases, wrongful convictions are solely based on the out-of-court confessions of accused persons obtained by police interrogators.This Article discusses existing law regarding confessions and convictions based on confessions. While this body of law deals in a relatively satisfactory manner with the fear that the confession is involuntary (primarily, through Miranda rules), unfortunately, it does not adequately address the serious fear of false confessions.The Article is designed to …

If You Could Read My Mind: Implications Of Neurological Evidence For Twenty-First Century Criminal Jurisprudence, John G. New

John G. New

The advent of new technologies has permitted cognitive neuroscientists to explore the neural mechanisms underlying deceptive behaviors. Lawyers and law enforcement entities have shown great interest in exploring the legal consequences of employing such technologies; indeed such interest extends back to the days of phrenology and the advent of polygraphy. This article recounts current advances in the development of “truth telling” technologies, particularly functional magnetic resonance imaging (fMRI) and Brain Fingerprinting and recent attempts to introduce the latter into court as scientific evidence. The second part of the article explores the challenges to constitutional jurisprudence, especially to the Fifth and …

Do Rules Of Evidence Apply (Only) In The Courtroom? Deceptive Interrogations In The United States And Germany, Jacqueline E. Ross

Jacqueline E Ross

Scholars who compare common law and civil law countries have long argued that civil law legal systems like Germany do not employ formal rules of evidence comparable to those which govern American courtrooms. The complex and restrictive nature of American evidentiary rules is said to be an artifact of the adversarial process and lay juries, which the legal system does not trust to evaluate evidence dispassionately. Civil law systems that commit fact-finding to mixed panels of lay and professional judges are said to have less need for formal rules of evidence that withhold information from decision-makers.

My essay challenges this …

Who Knew? Admissibility Of Subsequent Remedial Measures When Defendants Are Without Knowledge Of The Injuries, Mark Boyko, Ryan Vacca

Mark Boyko

Federal Rule of Evidence 407 prohibits the introduction of subsequent remedial measures for the purposes of demonstrating negligence, culpable conduct, or product defect. But the rule breaks down when a defendant undertakes the new safety measure after the plaintiff's injury, but before the defendant had knowledge of the loss. This situation is not uncommon. Toxic exposure cases represent a prime example where defendants are likely to have improvements before learning of a plaintiff's injury. Should evidence of these improvements be admissible? The literal text of Rule 407 suggests not. Yet admitting this evidence may not have the same chilling effect …

Criminal Performances: Film, Autobiography, And Confession, Jessica M. Silbey

Jessica Silbey

This article questions the criminal justice emphasis on filmed confession as the superlative evidentiary proffer that promotes accuracy and minimizes unconstitutional coercion by comparing filmed confessions to autobiographical film. It suggests that analyzing filmed confessions as a kind of autobiographical film exposes helpful tensions between the law’s reliance on confession as revealing the inner self and the literary and filmic conception of confession as constituting one self among many. Through a close examination of several filmed confessions along side an examination of the history of autobiographical writing and film, this article shows how filmed confessions do not reveal the truthfulness …
