Junk Science At Sentencing, Maneka Sinha

Faculty Scholarship

Junk science used in criminal trials has contributed to hundreds of wrongful convictions. But the problem is much worse than that. Junk science does not only harm criminal defendants who go to trial, but also the overwhelming majority of defendants—over ninety-five percent—who plead guilty, skip trial, and proceed straight to sentencing.

Scientific, technical, and other specialized evidence (“STS evidence”) is used regularly, and with increasing frequency, at sentencing. Despite this, Federal Rule of Evidence 702 and its state equivalents—which help filter unreliable STS evidence at trials—do not apply at the critical sentencing stage. In fact, at sentencing, no meaningful admissibility …

Unbuckling The Seat Belt Defense In Arkansas, Spencer G. Dougherty

Arkansas Law Review

The “seat belt defense” has been hotly litigated over the decades in numerous jurisdictions across the United States. It is an affirmative defense that, when allowed, reduces a plaintiff’s recovery for personal injuries resulting from an automobile collision where the defendant can establish that those injuries would have been less severe or avoided entirely had the plaintiff been wearing an available seat belt. This is an unsettled legal issue in Arkansas, despite the growing number of cases in which the seat belt defense is raised as an issue. Most jurisdictions, including Arkansas, initially rejected the defense, but the basis for …

Why Do We Admit Criminal Confessions Into Evidence?, David Crump

Seattle University Law Review

There is an enormous literature about the admissibility of criminal confessions. But almost all of it deals with issues related to self-incrimination or, to a lesser extent, with hearsay or accuracy concerns. As a result, the question whether we ever admit criminal confessions into evidence has not been the subject of much analysis. This gap is odd, since confessions are implicitly disfavored by a proportion of the literature and they often collide with exclusionary doctrines. Furthermore, the self-incrimination issue sometimes is resolved by balancing, and it would help if we knew what we were balancing. Therefore, one might ask: Why …

Brain Scans As Evidence: Truths, Proofs, Lies, And Lessons, Owen D. Jones, Francis X. Shen

Owen Jones

This contribution to the Brain Sciences in the Courtroom Symposium identifies and discusses issues important to admissibility determinations when courts confront brain-scan evidence. Through the vehicle of the landmark 2010 federal criminal trial U.S. v. Semrau (which considered, for the first time, the admissibility of brain scans for lie detection purposes) this article highlights critical evidentiary issues involving: 1) experimental design; 2) ecological and external validity; 3) subject compliance with researcher instructions; 4) false positives; and 5) drawing inferences about individuals from group data. The article’s lessons are broadly applicable to the new wave of neurolaw cases now being seen …

Between Brady Discretion And Brady Misconduct, Bennett L. Gershman

Dickinson Law Review (2017-Present)

The Supreme Court’s decision in Brady v. Maryland presented prosecutors with new professional challenges. In Brady, the Supreme Court held that the prosecution must provide the defense with any evidence in its possession that could be exculpatory. If the prosecution fails to timely turn over evidence that materially undermines the defendant’s guilt, a reviewing court must grant the defendant a new trial. While determining whether evidence materially undermines a defendant’s guilt may seem like a simple assessment, the real-life application of such a determination can be complicated. The prosecution’s disclosure determination can be complicated under the Brady paradigm because …

Where The Constitution Falls Short: Confession Admissibility And Police Regulation, Courtney E. Lewis

Dickinson Law Review (2017-Present)

A confession presented at trial is one of the most damning pieces of evidence against a criminal defendant, which means that the rules governing its admissibility are critical. At the outset of confession admissibility in the United States, the judiciary focused on a confession’s truthfulness. Culminating in the landmark case Miranda v. Arizona, judicial concern with the reliability of confessions shifted away from whether a confession was true and towards curtailing unconstitutional police misconduct. Post-hoc constitutionality review, however, is arguably inappropriate. Such review is inappropriate largely because the reviewing court must find that the confession was voluntary only by …

Every Juror Wants A Story: Narrative Relevance, Third Party Guilt And The Right To Present A Defense, John H. Blume, Sheri L. Johnson, Emily C. Paavola

Sheri Lynn Johnson

On occasion, criminal defendants hope to convince a jury that the state has not met its burden of proving them guilty beyond a reasonable doubt by offering evidence that someone else (a third party) committed the crime. Currently, state and federal courts assess the admissibility of evidence of third-party guilt using a variety of standards. In general, however, there are two basic approaches. Many state courts require a defendant to proffer evidence of some sort of direct link or connection between a specific third-party and the crime. A second group of state courts, as well as federal courts, admit evidence …

"Whodunit" Versus "What Was Done": When To Admit Character Evidence In Criminal Cases, Sherry Colb

Sherry Colb

In virtually every jurisdiction in the United States, the law of evidence prohibits parties from offering proof of an individual's general character traits to suggest that, on a specific occasion, the individual behaved in a manner consistent with those traits. In a criminal trial in particular, the law prohibits a prosecutor's introduction of evidence about the defendant's character as proof of his guilt. In this Article, Professor Colb proposes that the exclusion of defendant character evidence is appropriate in one category of cases but inappropriate in another. In the first category, which Professor Colb calls "whodunit" cases, the parties agree …

The Hidden Daubert Factor: How Judges Use Error Rates In Assessing Scientific Evidence, John B. Meixner Jr., Shari Seidman Diamond

Scholarly Works

In Daubert v. Merrell Dow Pharmaceuticals, the United States Supreme Court provided a framework under which trial judges must assess the evidentiary reliability of scientific evidence whose admissibility is challenged. One factor of the Daubert test, the “known or potential rate of error” of the expert’s method, has received considerably less scholarly attention than the other factors, and past empirical study has indicated that judges have a difficult time understanding the factor and use it less frequently in their analyses as compared to other factors. In this paper, we examine one possible interpretation of the “known or potential rate of …

The (In)Admissibility Of False Confession Expert Testimony, David A. Perez

Touro Law Review

This Comment discusses the relationship between police interrogation tactics and false confessions in order to address the admissibility of false confession expert testimony, a question that has traditionally been left to the discretion of the trial judge. The current literature-indeed, the prevailing consensus-argues for drastic changes to police interrogation practices to prevent false confessions and, in combination with such changes, demands that expert testimony on false confessions be admitted in criminal trials. Despite the relative unanimity in the literature, state and federal courts remain bitterly divided on the question of admissibility of false confession expert testimony. Each decision in this …

Shaken Baby Syndrome, Abusive Head Trauma, And Actual Innocence: Getting It Right, Keith A. Findley, Patrick D. Barnes, David A. Moran, Waney Squier

Articles

In the past decade, the existence of shaken baby syndrome (SBS) has been called into serious question by biomechanical studies, the medical and legal literature, and the media. As a result of these questions, SBS has been renamed abusive head trauma (AHT). This is, however, primarily a terminological shift: like SBS, AHT refers to the two-part hypothesis that one can reliably diagnose shaking or abuse from three internal findings (subdural hemorrhage, retinal hemorrhage, and encephalopathy) and that one can identify the perpetrator based on the onset of symptoms. Over the past decade, we have learned that this hypothesis fits poorly …

"Sweet Childish Days": Using Developmental Psychology Research In Evaluating The Admissibility Of Out-Of-Court Statements By Young Children, Lynn Mclain

All Faculty Scholarship

A three-year-old child, while being bathed by her babysitter, innocently mentions that her “pee-pee” hurts. When the babysitter asks the child how she hurt it, she says, “Uncle Ernie (her mother’s boyfriend) told me not to tell.” A subsequent medical examination reveals that the child has gonorrhea, a sexually transmitted disease.

By the time of trial, the child is four and-a-half-years old. When questioned by the trial judge, she cannot explain to the judge’s satisfaction, “the difference between the truth and a lie.” Moreover, she has no long term memory of the incident. The judge rules the child incompetent to …

The Nrc Report And Its Implications For Criminal Litigation, Paul C. Giannelli

Faculty Publications

The National Research Council, an arm of the National Academy of Sciences, issued a landmark report on forensic science in February 2009. In the long run, the report’s recommendations, if adopted, would benefit law enforcement and prosecutors. The recommendations would allow forensic science to develop a strong scientific basis and limit evidentiary challenges regarding the reliability of forensic evidence. In keeping with its congressional charge, however, the NRC Committee did not directly address admissibility issues. Nevertheless, given its content, the report will inevitably be cited in criminal cases. Indeed, within months, the United States Supreme Court cited the report, noting …

Post-Crawford: Time To Liberalize The Substantive Admissibility Of A Testifying Witness's Prior Consistent Statements, Lynn Mclain

All Faculty Scholarship

The United States Supreme Court's 1995 decision in Tome v. United States has read Federal Rule of Evidence 801(d)(1)(B) to prevent the prosecution's offering a child abuse victim's prior consistent statements as substantive evidence. As a result of that decision, the statements will also be inadmissible even for the limited purpose of helping to evaluate the credibility of a child, if there is a serious risk that the out-of-court statements would be used on the issue of guilt or innocence.

Moreover, after the Court's March 2004 decision in Crawford v. Washington, which redesigned the landscape of Confrontation Clause analysis, other …

The Sexual Innocence Inference Theory As A Basis For The Admissibility Of A Child Molestation Victim's Prior Sexual Conduct, Christopher B. Reid

Michigan Law Review

The sexual innocence inference refers to the thought process a jury follows when it hears a young child testify about sexual acts and matters that reveal an understanding of such acts beyond the capacity likely at his or her age. A jury is likely to assume that because the child is so young, he or she must be innocent of sexual matters. Shocked by the child's display on the witness stand, the jury may then infer that the child could have acquired such knowledge only if the charged offense of child molestation is true. To rebut this inference, a defendant …

Balancing The Right To Confrontation And The Need To Protect Child Sexual Abuse Victims: Are Statutes Authorizing Televised Testimony Serving Their Purpose?, Kimberley Seals Bressler

Seattle University Law Review

This Comment begins by providing a brief outline of the procedures regulating the use of televised testimony. Next, against the larger backdrop of the history of the right to confrontation, Part III addresses the treatment of televised testimony as hearsay. This section presents a recent Maryland decision as an illustration of the undesirable analogy of televised testimony to hearsay that leads to a more difficult admission standard. Part III concludes with the argument that televised testimony is the functional equivalent of in-court testimony, and thus, a hearsay analysis is inappropriate. Part IV of this Comment presents a recent Supreme Court …

Constitutional Constraints On The Admissibility Of Grand Jury Testimony: The Unavailable Witness, Confrontation, And Due Process, Barbara L. Strack

University of Michigan Journal of Law Reform

Defendants, however, have raised serious constitutional objections to the introduction of grand jury testimony when the witness is unavailable to testify at trial. These claims have focused on the confrontation clause of the sixth amendment and the due process clauses of the fifth and fourteenth amendments. Defendants have contended that the introduction of testimony from a grand jury proceeding which cannot be subjected to cross-examination fatally compromises the defendant's right to a fair trial. Lower courts are split over admitting grand jury testimony in these circumstances, and the Supreme Court has yet to rule on the issue. As a result, …
