The Missing Algorithm: Safeguarding Brady Against The Rise Of Trade Secrecy In Policing, Deborah Won

Michigan Law Review

Trade secrecy, a form of intellectual property protection, serves the important societal function of promoting innovation. But as police departments across the country increasingly rely on proprietary technologies like facial recognition and predictive policing tools, an uneasy tension between due process and trade secrecy has developed: to fulfill Brady’s constitutional promise of a fair trial, defendants must have access to the technologies accusing them, access that trade secrecy inhibits. Thus far, this tension is being resolved too far in favor of the trade secret holder—and at too great an expense to the defendant. The wrong balance has been struck.

Controlling The Jury-Teaching Function, Richard D. Friedman

Articles

When evidence with a scientific basis is offered, two fundamental questions arise. First, should it be admitted? Second, if so, how should it be assessed? There are numerous participants who might play a role in deciding these questions—the jury (on the second question only), the parties (through counsel), expert witnesses on each side, the trial court, the forces controlling the judicial system (which include, but are not limited to, the appellate courts), and the scientific establishment. In this Article, I will suggest that together, the last two—the forces controlling the judicial system and the scientific establishment—have a large role to …

Cabining Judicial Discretion Over Forensic Evidence With A New Special Relevance Rule, Emma F.E. Shoucair

Michigan Law Review

Modern forensic evidence suffers from a number of flaws, including insufficient scientific grounding, exaggerated testimony, lack of uniform best practices, and an inefficacious standard for admission that regularly allows judges to admit scientifically unsound evidence. This Note discusses these problems, lays out the current landscape of forensic science reform, and suggests the addition of a new special relevance rule to the Federal Rules of Evidence (and similar rules in state evidence codes). This proposed rule would cabin judicial discretion to admit non-DNA forensic evidence by barring prosecutorial introduction of such evidence in criminal trials absent a competing defense expert or …

Face-To-Face With Facial Recognition Evidence: Admissibility Under The Post-Crawford Confrontation Clause, Joseph Clarke Celentino

Michigan Law Review

In Crawford v. Washington, the Supreme Court announced a major change in Confrontation Clause doctrine, abandoning a decades-old framework that focused on the common law principles of hearsay analysis: necessity and reliability. The new doctrine, grounded in an originalist interpretation of the Sixth Amendment, requires courts to determine whether a particular statement is testimonial. But the Court has struggled to present a coherent definition of the term testimonial. In its subsequent decisions, the Court illustrated that its new Confrontation Clause doctrine could be used to bar forensic evidence, including laboratory test results, if the government failed to produce the …

Adaptation And The Courtroom: Judging Climate Science, Kirsten Engel, Jonathan Overpeck

Michigan Journal of Environmental & Administrative Law

Climate science is increasingly showing up in courtroom disputes over the duty to adapt to climate change. While judges play a critical role in evaluating scientific evidence, they are not apt to be familiar with the basic methods of climate science nor with the role played by peer review, publication, and training of climate scientists. This Article is an attempt to educate the bench and the bar on the basics of the discipline of climate science, which we contend is a distinct scientific discipline. We propose a series of principles to guide a judge’s evaluation of the reliability and weight …

A Tale Of Two Sciences, Erin Murphy

Michigan Law Review

It was the best of times, it was the worst of times . .. . So might one describe the contrasting portraits of DNA's ascension in the criminal justice system that are drawn in David Kaye's The Double Helix and the Law of Evidence and Sheldon Krimsky and Tania Simoncelli's Genetic Justice: DNA Data Banks, Criminal Investigations, and Civil Liberties. For Kaye, the double helix stands as the icon of twenty-first-century achievement, a science menaced primarily by the dolts (lawyers, judges, and the occasional analyst) who misuse it. For Krimsky and Simoncelli, DNA is a seductive forensic tool that is …

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 …

"False But Highly Persuasive": How Wrong Were The Probability Estimates In Mcdaniel V. Brown?, David H. Kaye

Michigan Law Review First Impressions

In McDaniel v. Brown, the Supreme Court will review the use of DNA evidence in a 1994 trial for sexual assault and attempted murder. The Court granted certiorari to consider two procedural issues—the standard of federal postconviction review of a state jury verdict for sufficiency of the evidence, and the district court's decision to allow the prisoner to supplement the record of trials, appeals, and state postconviction proceedings with a geneticist's letter twelve years after the trial. The letter from Laurence Mueller, a professor at the University of California at Irvine, identified two obvious mistakes in the state's expert testimony. …

Torts And Innovation, Gideon Parchomovsky, Alex Stein

Michigan Law Review

This Essay exposes and analyzes a hitherto overlooked cost of tort law: its adverse effect on innovation. Tort liability for negligence, defective products, and medical malpractice is determined by reference to custom. We demonstrate that courts' reliance on custom and conventional technologies as the benchmark of liability chills innovation and distorts its path. Specifically, recourse to custom taxes innovators and subsidizes replicators of conventional technologies. We explore the causes and consequences of this phenomenon and propose two possible ways to modify tort law in order to make it more welcoming to innovation.

Same Old, Same Old: Scientific Evidence Past And Present, Edward K. Cheng

Michigan Law Review

For over twenty years, and particularly since the Supreme Court's Daubert decision in 1993, much ink has been spilled debating the problem of scientific evidence in the courts. Are jurors or, in the alternative, judges qualified to assess scientific reliability? Do courts really need to be concerned about "junk science"? What mechanisms can promote better decision making in scientific cases? Even a cursory scan of the literature shows the recent explosion of interest in these issues, precipitating new treatises, hundreds of articles, and countless conferences for judges, practitioners, and academics. To this literature, Professor Tal Golan adds Laws of Men …

Bayes' Law, Sequential Uncertainties, And Evidence Of Causation In Toxic Tort Cases, Neal C. Stout, Peter A. Valberg

University of Michigan Journal of Law Reform

Judges are the gatekeepers of evidence. Arguably, the most difficult duty for a judicial gatekeeper is to screen the reliability of expert opinions in scientific fields such as medicine that are beyond the ken of most judges. Yet, judges have a duty to scrutinize such expert opinion evidence to determine its reliability and admissibility. In toxic tort cases, the issue of causation-whether the alleged exposures actually caused the plaintiffs injury-is nearly always the central dispute, and determining admissibility of expert causation opinion is a daunting challenge for most judges. We present a comprehensive review of the courts' struggles with the …

Electronic Discovery Sanctions In The Twenty-First Century, Shira A. Scheindlin, Kachana Wangkeo

Michigan Telecommunications & Technology Law Review

At the federal level, the Civil Rules Advisory Committee has responded to the "unique and necessary feature of computer systems--the automatic recycling, overwriting, and alteration of electronically stored information"--with a proposed amendment to Rule 37. The proposed Rule 37(f) would shield litigants from sanctions for the destruction of electronic data if the party "took reasonable steps to preserve the information after it knew or should have known the information was discoverable in the action" and "the failure resulted from the loss of the information because of the routine operation of the party's electronic information system." The safe harbor provision would …

Expert Information And Expert Evidence: A Preliminary Taxonomy, Samuel R. Gross, Jennifer L. Mnookin

Articles

Federal Rule of Evidence 702 speaks in very general terms. It governs every situation in which "scientific, technical or other specialized knowledge will assist the trier of fact," and provides that, in that situation, "a witness qualified as an expert by knowledge, skill, experience, or education, may testify thereto in the form of an opinion or otherwise . . . .' In 2000, following a trio of Supreme Court cases interpreting Rule 702, the Rule was amended to include a third requirement, in addition to the helpfulness of the testimony and the qualifications of the witness: reliability. Under Rule 702 …

Expert Testimony On Fingerprints: An Internet Exchange, Richard D. Friedman, David H. Kaye, Jennifer Mnookin, Dale Nance, Michael Saks

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.

Daubert's Backwash: Litigation-Generated Science, William L. Anderson, Barry M. Parsons, Drummond Rennie

University of Michigan Journal of Law Reform

In the 1993 landmark case Daubert v. Merrell Dow Pharmaceuticals, the United States Supreme Court articulated its position on the admissibility of scientific evidence. The Court reasoned that federal judges should rely on the processes scientists use to identify unreliable research, including the process of peer review, to determine when scientific evidence should be inadmissible. In response, lawyers and their clients, seeking to rely on such evidence, have begun funding and publishing their own research with the primary intention of providing support to cases they are litigating. This Article examines the phenomenon of litigation-generated science, how it potentially undermines …

Dna As Evidence: Viewing Science Through The Prism Of The Law, Peter Donnelly, Richard D. Friedman

Articles

In this article, we analyze a problem related to DNA evidence that is likely to be of great and increasing significance in the near future. This is the problem of whether, and how, to present evidence that the suspect has been identified through a DNA database search. In our view, the two well-known reports on DNA evidence issued by the National Research Council (NRC) have been badly mistaken in their analysis of this problem. The mistakes are significant because the reports have carried great authority with American courts; moreover, the DNA Advisory Board of the FBI has endorsed the second …

Jury Trial Techniques In Complex Civil Litigation, Ronald S. Longhofer

University of Michigan Journal of Law Reform

Ronald Longhofer, an experienced litigator, discusses the challenges inherent in trying a complex civil case to a jury. He explores aspects of complex litigation that often impede jurors from effectively hearing such cases. In conclusion, he suggests litigation techniques which have proved successful in overcoming such obstacles and effectively translating complex evidence to jurors.

Dna Database Searches And The Legal Consumption Of Scientific Evidence, Peter Donnelly, Richard D. Friedman

Articles

DNA evidence has transformed the proof of identity in criminal litigation, but it has also introduced daunting problems of statistical analysis into the process. In this Article, we analyze a problem related to DNA evidence that is likely to be of great and increasing significance in the near future. This is the problem of whether, and how, to present evidence that the suspect has been identified through a DNA database search. In our view, the two well-known reports on DNA evidence issued by the National Research Council ("NRC"), each of which has carried great authority with the American courts on …

Galileo's Revenge: Junk Science In The Courtroom, John F. Baughman

Michigan Law Review

A Review of Galileo's Revenge: Junk Science in the Courtroom by Peter W. Huber

The Future Of Evidence Law: Or, Some Prophecies About Proof, John W. Reed

Other Publications

I am honored to participate in this seminar that is part of the celebration surrounding the dedication of Colorado's new State Judicial Building. But that feeling of honor is tempered by an awareness of the responsibility and perils of the role I have been asked to play. With the assignment, "The Future of Evidence Law," I have been asked to play the prophet, to be a seer of sorts, and to suggest what rules and principles will govern proof at trials at some date in the future. Exactly what date was not specified in the invitation-a decade, perhaps? A generation? …

Evidence Problems In Criminal Cases, John W. Reed

Book Chapters

The Federal Rules of Evidence, enacted by Congress, became effective on July 1, 1975. Ten states have adopted state versions of the Federal Rules to govern trials in their courts, and about half the remaining states are considering whether to follow suit. Michigan is one of these latter states. Early in 1977 a committee appointed by the Supreme Court of Michigan proposed rules of evidence for Michigan closely patterned on the Federal Rules, and, if all goes well, the Court will promulgate rules for the Michigan courts to become effective in 1977 or soon thereafter. Michigan lawyers should be aware …

The Psychiatrist As An Expert Witness: Some Ruminations And Speculations, Bernard L. Diamond, David W. Louisell

Michigan Law Review

Consider the difference between the expert testimony of an orthopedic surgeon in a personal injury suit and the testimony of a psychiatrist in a murder trial in which some elements of the mens rea are at issue. In both instances an expert opinion is received in evidence, providing the trier of fact with technical, specialized information which must, or should, be available in order to permit a rational decision-making process. Well-established rules govern the nature of expert evidence and its mode of presentation. In legal theory, the orthopedic surgeon and the psychiatrist are both experts-physicians-who perform comparable functions in the …

Scientific Investigation And Defendants' Rights, B. J. George Jr.

Michigan Law Review

Advances in science, medicine and industry have made much of the world a more pleasant place in which to live. In general more men are living a physically more satisfying life in more comfortable surroundings than preceding generations. But with this has come a parallel increase in criminality to the point that the term "crime wave" is heard with increasing frequency. Many crimes are facilitated in their commission by adaption or application of new scientific discoveries by criminal elements. A natural consequence is that already overburdened police departments turn as quickly as is financially possible to new scientific techniques in …

Social Scientists Take The Stand: A Review And Appraisal Of Their Testimony In Litigation, Jack Greenberg

Michigan Law Review

"How to inform the judicial mind, as you know, is one of the most complicated problems,'' said Justice Frankfurter during argument of the school segregation cases. And as law deals more and more with issues of great public consequence the judiciary's need for knowledge increases. Much of this knowledge is within the realm of what are called the social sciences.

Although jurisprudents and social scientists have long complained of a gulf between law and social science, little notice has been given to the recent, recurrent collaboration between the two at the trial level. In a variety of cases social scientists' …

Evidence - Validity Of Statutory Presumption Of Intoxication From A Finding Of 0.15 Percent Concentration Of Alcohol In The Blood, Donald F. Oosterhouse S.Ed.

Michigan Law Review

Defendant was tried and convicted of the statutory crime of driving an automobile while under the influence of intoxicating liquor. The state introduced into evidence the result of a blood test, voluntarily submitted to by the defendant, which showed 0,20% concentration of alcohol in the defendant's blood. Arizona statutes established a rebuttable presumption of no intoxication if such tests showed a concentration of 0.05%, or less, of alcohol in one's blood, and of intoxication if the tests showed a concentration of 0.15%, or more. Breath, urine, and direct blood tests are authorized by the statute. Defendant argued that the statute …
