Neuropsychological Malingering Determination: The Illusion Of Scientific Lie Detection, Chunlin Leonhard, Christoph Leonhard
Neuropsychological Malingering Determination: The Illusion Of Scientific Lie Detection, Chunlin Leonhard, Christoph Leonhard
Georgia Law Review
Humans believe that other humans lie, especially when stakes are high. Stakes can be very high in a courtroom, from substantial amounts of monetary damages in civil litigation to liberty or life in criminal cases. One of the most frequently disputed issues in U.S. courts is whether litigants are malingering when they allege physical or mental conditions for which they are seeking damages or which would allow them to avoid criminal punishment. Understandably, creating a scientific method to detect lies is very appealing to all persons engaged in lie detection. Neuropsychologists claim that they can use neuropsychological assessment tests (Malingering …
How Florida’S Courts Should Evaluate The Admissibility Of Field Sobriety Testing And Blood Thc Levels Evidence In Marijuana Impaired Driving Prosecutions, Christopher Bomhoff
How Florida’S Courts Should Evaluate The Admissibility Of Field Sobriety Testing And Blood Thc Levels Evidence In Marijuana Impaired Driving Prosecutions, Christopher Bomhoff
FIU Law Review
Field sobriety and blood alcohol concentration tests are proven reliable techniques to determine whether a person us under the influence of alcohol. No such technique has been developed to reliably determine whether a person is under the influence of marijuana. However, despite a lack of scientific consensus regarding the reliability of field sobriety and blood toxicology tests to determine marijuana impairment, these methods are routinely used as evidence of guilt in marijuana impaired driving prosecutions. Twenty-four states have legalized the recreational use of marijuana, and Florida appears to be set to join them in the near future. As a result …
Brain Scans As Evidence: Truths, Proofs, Lies, And Lessons, Owen D. Jones, Francis X. Shen
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 …

Life After Daubert V. Merrell Dow: Maine As A Case Law Laboratory For Evidence Rule 702 Without Frye, Leigh Stephens Mccarthy
Life After Daubert V. Merrell Dow: Maine As A Case Law Laboratory For Evidence Rule 702 Without Frye, Leigh Stephens Mccarthy
Maine Law Review
In reaching its recent decision in Daubert v. Merrell Dow Pharmaceuticals, Inc., the United States Supreme Court grappled not with case law but with fundamental questions about the nature of science and its role in law. The court in Daubert addressed the problematic issue of admissibility of expert scientific testimony. In the end the Court rejected as an exclusionary rule the venerable standard set in 1923 by Frye v. United States. Frye held that scientific testimony was to be excluded unless it had gained “general acceptance” in its field. Daubert held that Rule 702 of the Federal Rules of Evidence …
Scientific Evidence And Forensic Science Since Daubert: Maine Decides To Sit Out On The Dance, Thomas L. Bohan
Scientific Evidence And Forensic Science Since Daubert: Maine Decides To Sit Out On The Dance, Thomas L. Bohan
Maine Law Review
In 1993, the Supreme Court of the United States stated that with the federal adoption of statutory rules of evidence in 1975, the common law rule for determining admissibility of scientific testimony was superseded, and that thenceforth admissibility of scientific testimony was to be determined solely by Federal Rule of Evidence 702 (Rule 702). The Frye standard had been adopted in one form or another by most of the federal circuits and by many of the state courts during the 70 years preceding Daubert. Referred to as the “general acceptance” standard, the Frye standard--although adopted in a variety of forms--had …

Innocent Suffering: The Unavailability Of Post-Conviction Relief In Virginia Courts, Kaitlyn Potter
Innocent Suffering: The Unavailability Of Post-Conviction Relief In Virginia Courts, Kaitlyn Potter
University of Richmond Law Review
This comment examines actual innocence in Virginia: the progress it has made, the problems it still faces, and the possibilities for reform. Part I addresses past reform to the system, spurred by the shocking tales of Thomas Haynesworth and others. Part II identifies three of the most prevalent systemic challenges marring Virginia's justice system: (1) flawed scientific evidence; (2) the premature destruction of evidence; and (3) false confessions and guilty pleas. Part III suggests ways in which Virginia can, and should, address these challenges to ensure that the justice system is actually serving justice.
Empiricism In Daubert And The California Supreme Court In Sargon, Robert Sanger
Empiricism In Daubert And The California Supreme Court In Sargon, Robert Sanger
Robert M. Sanger
California has become a Daubert state. In Sargon v. The University of Southern California, the California Supreme Court held that judges are the “gatekeepers” with regard to expert or scientific evidence in this state, just as has been the case in the federal system (and many other states) since the decision in Daubert. Now that California is avowedly a Daubert state, it is important to understand why courtroom evidence – scientific, expert or, for that matter, otherwise – is properly grounded in empiricism. Empiricism is the theory that knowledge is derived from experience. Understanding this empirical basis for both Daubert …

Dangerousness And Expertise Redux, Christopher Slobogin
Dangerousness And Expertise Redux, Christopher Slobogin
ExpressO
Civil commitment, confinement under sexual predator laws, and many capital and noncapital sentences depend upon proof of a propensity toward violence. This article discusses the current state of prediction science, in particular the advantages and disadvantages of clinical and actuarial prediction, and then analyzes how the rules of evidence should be interpreted in deciding whether opinions about propensity should be admissible. It concludes that dangerousness predictions that are not based on empirically-derived probability estimates should be excluded from the courtroom unless the defense decides otherwise. This conclusion is not bottomed on the usual concern courts and commentators raise about expert …
Scientific Evidence And The Ethical Obligations Of Attorneys, Michael J. Saks
Scientific Evidence And The Ethical Obligations Of Attorneys, Michael J. Saks
Cleveland State Law Review
This article considers the question: "What are the legal and ethical responsibilities of attorneys when offering scientific expert evidence to courts?" To a lesser extent it considers the responsibilities of attorneys to challenge such evidence when proffered and the ethical dimensions of the working relationship of lawyers and experts. Although the most prominent discussions of such issues have concerned so-called junk science in civil trials, the legal context upon which this article will focus is the criminal trial, where dubious science is more common, less questioned, and has even become institutionalized. The rules and practices of civil cases are provided …
