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.

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 …

The Future Of Confession Law: Toward Rules For The Voluntariness Test, Eve Brensike Primus

Michigan Law Review

Confession law is in a state of collapse. Fifty years ago, three different doctrines imposed constitutional limits on the admissibility of confessions in criminal cases: Miranda doctrine under the Fifth Amendment, Massiah doctrine under the Sixth Amendment, and voluntariness doctrine under the Due Process Clauses of the Fifth and Fourteenth Amendments. But in recent years, the Supreme Court has gutted Miranda and Massiah, effectively leaving suspects with only voluntariness doctrine to protect them during police interrogations. The voluntariness test is a notoriously vague case-by-case standard. In this Article, I argue that if voluntariness is going to be the framework for …

Disentangling Michigan Court Rule 6.502(G)(2): The "New Evidence" Exception To The Ban On Successive Motions For Relief From Judgment Does Not Contain A Discoverability Requirement, Claire V. Madill

Michigan Law Review

Michigan courts are engaging in a costly interpretative mistake. Confused by the relationship between two distinct legal doctrines, Michigan courts are conflating laws in a manner that precludes convicted defendants from raising their constitutional claims in postconviction proceedings. In Michigan, a convicted defendant who wishes to collaterally attack her conviction must file a 6.500 motion. The Michigan Court Rules generally prohibit “second or subsequent” motions. Nonetheless, section 6.502(G)(2) permits a petitioner to avoid this successive motion ban if her claim relies on “new evidence that was not discovered” before her original postconviction motion. Misguided by the similarity between the language …

Proving Personal Use: The Admissibility Of Evidence Negating Intent To Distribute Marijuana, Stephen Mayer

Michigan Law Review

Against the backdrop of escalating state efforts to decriminalize marijuana, U.S. Attorneys’ Offices continue to bring drug-trafficking prosecutions against defendants carrying small amounts of marijuana that are permitted under state law. Federal district courts have repeatedly barred defendants from introducing evidence that they possessed this marijuana for their own personal use. This Note argues that district courts should not exclude three increasingly common kinds of “personal use evidence” under Federal Rules of Evidence 402 and 403 when that evidence is offered to negate intent to distribute marijuana. Three types of personal use evidence are discussed in this Note: (1) a …

Making The Right Call For Confrontation At Felony Sentencing, Shaakirrah R. Sanders

University of Michigan Journal of Law Reform

Felony sentencing courts have discretion to increase punishment based on un-cross-examined testimonial statements about several categories of uncharged, dismissed, or otherwise unproven criminal conduct. Denying defendants an opportunity to cross-examine these categories of sentencing evidence undermines a core principle of natural law as adopted in the Sixth Amendment: those accused of felony crimes have the right to confront adversarial witnesses. This Article contributes to the scholarship surrounding confrontation rights at felony sentencing by cautioning against continued adherence to the most historic Supreme Court case on this issue, Williams v. New York. This Article does so for reasons beyond the unacknowledged …

A Model For Fixing Identification Evidence After Perry V. New Hampshire, Robert Couch

Michigan Law Review

Mistaken eyewitness identifications are the leading cause of wrongful convictions. In 1977, a time when the problems with eyewitness identifications had been acknowledged but were not yet completely understood, the Supreme Court announced a test designed to exclude unreliable eyewitness evidence. This standard has proven inadequate to protect against mistaken identifications. Despite voluminous scientific studies on the failings of eyewitness identification evidence and the growing number of DNA exonerations, the Supreme Court's outdated reliability test remains in place today. In 2012, in Perry v. New Hampshire, the Supreme Court commented on its standard for evaluating eyewitness evidence for the first …

Empty Promises: Miranda Warnings In Noncustodial Interrogations, Aurora Maoz

Michigan Law Review

You have the right to remain silent; anything you say can be used against you in a court of law. You have the right to an attorney; if you cannot afford an attorney, one will be provided to you at the state's expense. In 2010, the Supreme Court declined an opportunity to resolve the question of what courts should do when officers administer Miranda warnings in a situation where a suspect is not already in custody-in other words, when officers are not constitutionally required to give or honor these warnings. While most courts have found a superfluous warning to be …

Party's Over: Admissibility Of Post-Trial Juror Testimony Should Depend On The Nature Of The Conduct, Justin Gillett

University of Michigan Journal of Law Reform Caveat

What do you call a weeklong period in which you and a handful of acquaintances drink alcohol every day at lunch, sleep though the afternoons, smoke marijuana and ingest a couple lines of cocaine on occasion? You call it the time when a jury convicted Anthony Tanner and William Conover of conspiracy to defraud the United States and commit various acts of mail fraud. Under a current rule of evidence, which precludes juror testimony to impeach a verdict except on extraneous prejudicial information, juror intoxication is not an external influence about which jurors may testify. A new test for the …

J.D.B. V. North Carolina And The Reasonable Person, Christopher Jackson

Michigan Law Review First Impressions

This Term, the Supreme Court was presented with a prime opportunity to provide some much-needed clarification on a "backdrop" issue of law-one of many topics that arises in a variety of legal contexts, but is rarely analyzed on its own terms. In J.D.B. v. North Carolina, the Court considered whether age was a relevant factor in determining if a suspect is "in custody" for Miranda purposes, and thus must have her rights read to her before being questioned by the police. Miranda, like dozens of other areas of law, employs a reasonable person test on the custodial question: it asks …

Proposal To Reverse The View Of A Confession: From Key Evidence Requiring Corroboration To Corroboration For Key Evidence, Boaz Sangero, Mordechai Halpert

University of Michigan Journal of Law Reform

Both case law and legal literature have recognized that all, and not just clearly statistical, evidence is probabilistic. Therefore, we have much to learn from the laws of probability with regard to the evaluation of evidence in a criminal trial. The present Article focuses on the confession. First, we review legal and psychological literature and show that the probability of a false confession and, consequently, a wrongful conviction, is far from insignificant. In light of this, we warn against the cognitive illusion, stemming from the fallacy of the transposed conditional, which is liable to mislead the trier of fact in …

Confrontation And Domestic Violence Post-Davis: Is There And Should There Be A Doctrinal Exception, Eleanor Simon

Michigan Journal of Gender & Law

Close to five million intimate partner rapes and physical assaults are perpetrated against women in the United States annually. Domestic violence accounts for twenty percent of all non-fatal crime experienced by women in this county. Despite these statistics, many have argued that in the past six years the Supreme Court has "put a target on [the] back" of the domestic violence victim, has "significantly eroded offender accountability in domestic violence prosecutions," and has directly instigated a substantial decline in domestic violence prosecutions. The asserted cause is the Court's complete and groundbreaking re-conceptualization of the Sixth Amendment right of a criminal …

"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. …

Davis And Hammon: A Step Forward, Or A Step Back?, Tom Lininger

Michigan Law Review First Impressions

Prosecutors, defense attorneys, and lower court judges hoped that the Supreme Court’s ruling in the consolidated cases of Davis v. Washington and Hammon v. Indiana (hereafter simply Davis) would provide a primer on testimonial hearsay. In retrospect, these hopes were somewhat unrealistic. The Davis ruling could not possibly clear up all the confusion that followed Crawford v. Washington, the landmark 2004 case in which the Court strengthened the right of the accused to confront declarants of testimonial hearsay. In Davis, the Court focused on the facts under review and developed a taxonomy that will be useful in similar cases, but …

Circling Around The Confrontation Clause: Redefined Reach But Not A Robust Right, Lisa Kern Griffin

Michigan Law Review First Impressions

The Supreme Court’s consolidated ruling in United States v. Davis and United States v. Hammon is a classic of the genre of consensus opinions to which the Roberts Court aspired in its first, transitional term. The opinion, authored by Justice Scalia, contains practical accommodations unusual in a decision by the Court’s fiercest proponent of first principles. The restraint that characterized the term is, of course, more about considerations of logistics (including the desire to avoid re-arguments after the mid-term replacement of Justice O’Connor) than about the alignment of logic. Because it reflects temporary institutional constraints rather than intellectual agreement, the …

Davis/Hammon, Domestic Violence, And The Supreme Court: The Case For Cautious Optimism, Joan S. Meier

Michigan Law Review First Impressions

The Supreme Court’s consolidated decision in Davis v. Washington and Hammon v. Indiana offers something for everyone: by “splitting the difference” between the two cases—affirming one and reversing the other—the opinion provides much grist for advocates’ mills on both sides of this issue. While advocates for defendants’ rights are celebrating the opinion’s continued revitalization of the right to confrontation, which began in Crawford v. Washington, advocates for victims have cause for celebration as well: the decision is notable for its reflection of the Court’s growing—albeit incomplete— awareness and understanding of the dynamics of domestic violence and their implications for justice. …

Still "Left In The Dark": The Confrontation Clause And Child Abuse Cases After Davis V. Washington, Anthony J. Franze, Jacob E. Smiles

Michigan Law Review First Impressions

In his concurring opinion in Crawford v. Washington, Chief Justice Rehnquist criticized the majority for holding that the Confrontation Clause applies to “testimonial” statements but leaving for “another day” any effort to define sufficiently what “testimonial” means. Prosecutors and defendants, he said, “should not be left in the dark in this manner.” Over the next two years, both sides grappled with the meaning of testimonial, each gleaning import from sections of Crawford that seemingly proved their test was the right one. When the Court granted certiorari in Davis v. Washington and Hammon v. Indiana (hereinafter Davis), hopes were high that …

Davis V. Washington And Hammon V. Indiana: Beating Expectations, Robert P. Mosteller

Michigan Law Review First Impressions

I begin with a question of effectiveness: does the new Confrontation Clause doctrine effectively protect defendants with respect to the most im-portant types of problematic out-of-court statements? Although they leave much room for the introduction of hearsay in the immediate aftermath of crime generally, Davis v. Washington and Hammon v. Indiana (together hereinafter Davis) are better opinions from that broad perspective than I had feared. The new doctrine now covers and provides substantial procedural protection for a very important class of problematic hearsay—statements made to government agents investigating past crime.

Refining Crawford: The Confrontation Claus After Davis V. Washington And Hammon V. Indiana, Andrew C. Fine

Michigan Law Review First Impressions

Clarification of the Supreme Court’s newly minted interpretation of the Confrontation Clause was desperately needed, and Davis v. Washington and Hammon v. Indiana promised to provide it. Two terms earlier, in Crawford v. Washington, the Supreme Court had worked a revolutionary transformation of Confrontation Clause analysis by overruling Ohio v. Roberts and severing the link between hearsay jurisprudence and the Clause. Crawford was hailed by the criminal defense bar, since it seemed to presage a sharp reduction in the frequency of so-called “victimless” trials by holding that “testimonial” hearsay, no matter how reliable, was constitutionally inadmissible in the absence of …

Proposed Amendments To Fed. R. Crim. P. 26: An Exchange: Remote Testimony - A Prosecutor's Perspective, Lynn Helland

University of Michigan Journal of Law Reform

Although the Supreme Court has declined, for now, to endorse the Judicial Conference proposal to add a Rule 26(b) of the Federal Rules of Criminal Procedure to permit live video testimony under limited circumstances, I agree with Professor Friedman that the matter is far from over. This is both because the potential benefits to be realized from the use of remote video testimony are too large to ignore and because, on closer inspection, any Confrontation Clause concerns that might underlie the Court's hesitation to adopt the proposal are not warranted. My purpose in writing is to summarize some of the …

Establishing Inevitability Without Active Pursuit: Defining The Inevitable Discovery Exception To The Fourth Amendment Exclusionary Rule, Stephen E. Hessler

Michigan Law Review

Few doctrines of constitutional criminal procedure generate as much controversy as the Fourth Amendment exclusionary rule. Beyond the basic mandate of the rule - that evidence obtained in violation of an individual's right to be secure against unreasonable search and seizure is inadmissible in a criminal proceeding - little else is agreed upon. The precise date of the exclusionary rule's inception is uncertain, but it has been applied by the judiciary for over eight decades. While the Supreme Court has emphasized that the rule is a "judicially created remedy," and not a "personal constitutional right," this characterization provokes argument as …

Time For Final Action On 18 U.S.C. § 3292, Abraham Abramovsky, Jonathan I. Edelstein

Michigan Journal of International Law

18 U.S.C. § 3292 was enacted in order to meet a compelling prosecutorial need-the increasing necessity of obtaining evidence from abroad via procedures which are frequently time-consuming. However, the statute contains numerous ambiguities, as well as built-in disadvantages both to prosecutors and defendants, which diminish its value as a prosecutorial evidence-gathering device while increasing the possibility that defendants' rights and expectations will be violated. However, it is possible to interpret the statute in a manner which is consistent with its terms and purpose and which concomitantly preserves the rights of the Government and of grand jury targets.

Reconceiving The Right To Present Witnesses, Richard A. Nagareda

Michigan Law Review

Modem American law is, in a sense, a system of compartments. For understandable curricular reasons, legal education sharply distinguishes the law of evidence from both constitutional law and criminal procedure. In fact, the lines of demarcation between these three subjects extend well beyond law school to the organization of the leading treatises and case headnotes to which practicing lawyers routinely refer in their trade. Many of the most interesting questions in the law, however, do not rest squarely within a single compartment; instead, they concern the content and legitimacy of the lines of demarcation themselves. This article explores a significant, …

The Emerging International Consensus As To Criminal Procedure Rules, Craig M. Bradley

Michigan Journal of International Law

This article will demonstrate that these general claims, as well as certain observations about specific countries, were, with one significant exception, substantially wrong when they were written. More importantly, due to significant developments in several countries in the years since those reports came out, they are even more wrong now. That is, not only have the U.S. concepts of pre-interrogation warnings to suspects, a search warrant requirement, and the use of an exclusionary remedy to deter police misconduct been widely adopted, but in many cases other countries have gone beyond the U.S. requirements.

The Admission Of Criminal Histories At Trial, Department Of Justice Office Of Legal Policy

University of Michigan Journal of Law Reform

As part of a continuing series of studies on impediments to the search for truth in criminal investigation and adjudication, the Office of Legal Policy has carried out a review of the law governing the admission of the criminal records of defendants and other persons at trial. The results of this review are set out in this Report.

The Search And Seizure Exclusionary Rule, Department Of Justice Office Of Legal Policy

University of Michigan Journal of Law Reform

The fourth amendment guarantees the "right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures." This guaranty is not self-executing, however, and the courts and criminal justice systems in this country have long been bedeviled by questions concerning appropriate methods of ensuring its observance. As a result of the Supreme Court's decisions in Weeks v. United States and Mapp v. Ohio, the method principally relied upon today is a judicially created rule excluding from criminal trials evidence obtained in violation of the defendant's fourth amendment rights.

Police-Obtained Evidence And The Constitution: Distinguishing Unconstitutionally Obtained Evidence From Unconstitutionally Used Evidence, Arnold H. Loewy

Michigan Law Review

The article will consider four different types of police-obtained evidence: evidence obtained from an unconstitutional search and seizure, evidence obtained from a Miranda violation, confessions and lineup identifications obtained in violation of the sixth amendment right to counsel, and coerced confessions. My conclusions are that evidence obtained from an unconstitutional search and seizure is excluded because of the police misconduct by which it was obtained. On the other hand, evidence obtained from a Miranda violation is (or ought to be) excluded because use of that evidence compromises the defendant's procedural right not to be compelled to be a witness against …

Confusing The Fifth Amendment With The Sixth: Lower Court Misapplication Of The Innis Definition Of Interrogation, Jonathan L. Marks

Michigan Law Review

This Note examines how these courts have applied or misapplied Innis, and concludes that, while many of these decisions are consistent with Miranda and Innis, too many others are not. In order to evaluate these cases, it is first necessary to understand the meaning and significance of Innis. Part I thus considers Innis and its background. Part II then examines lower court decisions applying the Innis test, dividing these decisions into six groups based on the most common factual scenarios. Because the cases deal with factually specific police practices, this method constitutes the most useful way to …
