Probability, Individualization, And Uniqueness In Forensic Science Evidence: Listening To The Academies, David H. Kaye

Faculty Scholarship

Day in and day out, criminalists testify to positive, uniquely specific identifications of fingerprints, bullets, handwriting, and other trace evidence. A committee of the National Academy of Sciences, building on the writing of academic commentators, has called for sweeping changes in the presentation and production of evidence of identification. These include some form of circumscribed and standardized testimony. But the Academy report is short on the specifics of the testimony that would be legally and professionally allowable. This essay outlines possible types of testimony that might harmonize the testimony of criminalists with the actual state of forensic science. It does …

Truth Or Consequences: Self-Incriminating Statements And Informant Veracity, Mary Nicol Bowman

Faculty Articles

Courts treat self-incriminating statements by criminal informants as a significant factor favoring the reliability of the informant’s information when making probable cause determinations for the issuance of search warrants. Courts do so even though admissions of criminal activity usually undercut, rather than support, credibility. In using self-incriminating statements to support the informant’s reliability, courts tend to rely on a theory with significant theoretical flaws. Furthermore, recent United States Supreme Court jurisprudence in other contexts undercuts the reliability of using self-incriminating statements to support the veracity of other information. If courts adequately scrutinize the informant’s self-incriminating statements and the circumstances surrounding …

Relative Doubt: Familial Searches Of Dna Databases, Erin Murphy

Michigan Law Review

The continued growth of forensic DNA databases has brought about greater interest in a search method known as "familial" or "kinship" matching. Whereas a typical database search seeks the source of a crime-scene stain by making an exact match between a known person and the DNA sample, familial searching instead looks for partial matches in order to find potential relatives of the source. The use of a familial DNA search to identify the alleged "Grim Sleeper" killer in California brought national attention to the method, which has many proponents. In contrast, this Article argues against the practice of familial searching …

New Pleading, New Discovery, Scott Dodson

Michigan Law Review

Pleading in federal court has a new narrative. The old narrative was one of notice, with the goal of broad access to the civil justice system. New Pleading, after the landmark Supreme Court cases of Twombly and Iqbal, is focused on factual sufficiency, with the purpose of screening out meritless cases that otherwise might impose discovery costs on defendants. The problem with New Pleading is that factual insufficiency often is a poor proxy for meritlessness. Some plaintifs lack sufficient factual knowledge of the elements of their claims not because the claims lack merit but because the information they need is …

Liar! Liar! Impeaching A Witness On Cross-Examination, Maureen A. Howard

Articles

There are certain trial moments that can set an advocate’s heart a-flutter. One is the opportunity to show the jury that an adverse witness is not to be trusted. Even better is the chance to expose the witness to be a bald-faced liar.

Welcome to the wonderful world of impeachment. Impeachment is the art of discrediting the witness on cross-examination. There are seven impeachment techniques:

• Bias, interest, and motive

• Contradictory facts

• Prior convictions — FRE 609

• Prior bad acts — FRE 608 (b)

• Prior inconsistent statements — FRE 613

• Bad character for truthfulness — …

"I'M Dying To Tell You What Happened": The Admissibility Of Testimonial Dying Declarations Post-Crawford, Peter Nicolas

Articles

This Article demonstrates the existence and delineates the scope of a federal constitutional definition of "dying declarations" that is distinct from the definitions set forth in the Federal Rules of Evidence and their state counterparts. This Article further demonstrates that states have state constitutional definitions of "dying declarations" (for purposes of interpreting state constitutional analogues to the Confrontation Clause of the Sixth Amendment) that may differ in important respects from the federal constitutional definition of "dying declarations."

This Article then shows that some of the definitions of "dying declarations" contained in federal and state hearsay exceptions exceed the federal and …

Another "Straightforward Application": The Impact Of Melendez-Diaz On Forensic Testing And Expert Testimony In Controlled Substance Cases, John Wait

Campbell Law Review

Part I of this Article will analyze Melendez-Diaz with a focus on extracting indicators within the opinion that lend guidance as to how the opinion could be extended to Bullcoming and to expert testimony based on forensic reports in controlled substance cases. Part II will provide an overview of the tests utilized by the SBI to determine the nature and quantity, if any, of suspected controlled substances with the goal of ascertaining who, under Melendez-Diaz, should be subject to confrontation. Part III will provide a prediction of the outcome in Bullcoming. Finally, Part IV will review the pending cases from …

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 …

Countermeasure Mechanisms In A P300-Based Concealed Information Test, John B. Meixner Jr., J. Peter Rosenfeld

Scholarly Works

The detection of deception has been the focus of much research in the past 20 years. Though much controversy has surrounded one deception detection protocol, the “Control Question Test” (NRC 2003, Ben-Shakhar 2002), an alternative test, the Guilty Knowledge Test (GKT), developed by Lykken (1959, 1960), is based on scientific principles and has been well-received in the scientific community. The GKT presents subjects with various stimuli, one of which is a guilty knowledge item (termed the probe, such as the gun used to commit a crime). The other stimuli in the test consist of control items that are of the …

Much Uncertainty About Uncertain Tax Positions, Robert D. Probasco

Faculty Scholarship

The Internal Revenue Service (IRS) announced in January 2010 a new initiative to require certain businesses to report “uncertain tax positions” on a new schedule filed with their annual tax returns. Draft schedules and instructions issued in April 2010 clarified some of the mechanical aspects of the new requirement but left many open issues and questions. The IRS proposal built on requirements by the Financial Accounting Standards Board (FASB) in FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes (“FIN 48”). The standard requires companies, in their financial statements, to reserve some of the benefits from any position taken …

Constructing Systemic Safeguards Against Informant Perjury, Peter A. Joy

Scholarship@WashULaw

Reliance on an informant's testimony as the primary basis for charging and convicting the accused is fraught with problems. While the hypothetical explicitly addresses the ethical dilemmas defense counsel faces when her client is trading false testimony in exchange for a reduced charge and shorter sentence, the hypothetical also implicitly illustrates the inadequacies of our criminal justice system's current handling of testimony from cooperating witnesses.

The focus on the ethical, and perhaps moral, obligations of Lawyer representing a potentially perjurious Client begs larger questions. Are there safeguards the prosecutor's office could employ to ensure that the trial prosecutor, who is …

The Disordered And Discredited Plaintiff: Psychiatric Evidence In Civil Litigation, Deirdre M. Smith

Cardozo Law Review

This Article examines civil defendants' use of evidence of a plaintiff's alleged current or prior psychiatric diagnosis or treatment by analyzing and critiquing the three primary rationales offered in support of the relevancy of such evidence: (1) to suggest an alternative cause of the plaintiff's alleged psychological injuries; (2) to impeach the plaintiff's credibility by asserting that a mental illness interferes with the plaintiff's ability to recount or to perceive events accurately; and (3) to reveal certain propensities that inform how the plaintiff likely acted with respect to the events at issue in the litigation. While attaching a label of …

Electronic Records And The Law Of Evidence In Canada: The Uniform Electronic Evidence Act Twelve Years Later, Luciana Duranti, Corinne M. Rogers, Anthony F. Sheppard

All Faculty Publications

This article analyzes the adequacy of The Uniform Electronic Evidence Act, twelve years after its adoption, in dealing with the complexity of the records created, used, or stored in the digital environment. In the face of rapidly changing technology, the authors believe that the nature and characteristics of electronic records cannot be accounted for by simple modifications to the existing law of evidence, but require a new enactment following upon a close collaboration among records professions, legal and law enforcement professions, and the information technology profession. The new rules, comprehensively encompassing issues of relevance, admissibility, and weight of electronic documentary …

A Second Chance At Justice: Why States Should Adopt Aba Model Rules Of Professional Conduct 3.8(G) And (H), Michele K. Mulhausen

University of Colorado Law Review

Prosecutors, defense attorneys, jurists, and citizens alike cringe at the thought of their fellow citizens serving criminal sentences for crimes that they did not commit. Unfortunately, evidence sometimes emerges after conviction that would exonerate the defendant. As a result, in February 2008, the American Bar Association adopted two amendments, (g) and (h), to the existing Model Rule 3.8, which governs the conduct of prosecutors. The two amendments place an affirmative duty on prosecutors to investigate "new, credible and material evidence." If the evidence creates a "reasonable likelihood" that the convicted defendant did not commit the crime, the prosecutor must "seek …
