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 …

In Search Of A Theory Of Public Memory: The State, The Individual, And Marcel Proust, Brian F. Havel

Brian Havel

This Article posits the existence and pervasiveness of an official public (or State) memory that is primarily constructed using public law devices and statements of official policy. While official public memory serves the purposes of social control and stability, it also seeks to mask contestation and is, accordingly, neither complete nor authentic. Using philosophical, scientific, and literary sources, this Article demonstrates how the affective (emotional) memory that is unique to individuals creates a permanent potential for contestation and authenticity and therefore sets a natural conceptual limit to the power of officially managed memory to contrive the past. To help establish …

Leveling Felony Charges For Withholding Evidence, Jodi Nagzger

Jodi Nafzger

This Article addresses the intersection of the rule of Brady v. Maryland, 373 U.S. 83 (1963), and ABA Model Rule of Professional Conduct 3.8. Brady requires prosecutors to automatically disclose materially exculpatory evidence in the government’s possession to the defense. ABA Model Rule 3.8 requires a prosecutor in a criminal case “to make timely disclosure to the defense of all evidence or information known to the prosecutor that tends to negate the guilt of the accused or mitigates the offense.” The ABA issued a formal opinion in 2009 which concluded that the prosecutor’s ethical duty under 3.8 is broader in …

Surprise Vs. Probability As A Metric For Proof, Edward K. Cheng, Matthew Ginther

Edward Cheng

In this Symposium issue celebrating his career, Professor Michael Risinger in Leveraging Surprise proposes using "the fundamental emotion of surprise" as a way of measuring belief for purposes of legal proof. More specifically, Professor Risinger argues that we should not conceive of the burden of proof in terms of probabilities such as 51%, 95%, or even "beyond a reasonable doubt." Rather, the legal system should reference the threshold using "words of estimative surprise" -asking jurors how surprised they would be if the fact in question were not true. Toward this goal (and being averse to cardinality), he suggests categories such …

Impeaching Lying Parties With Their Statements During Negotiation: Demysticizing The Public Policy Rationale Behind Evidence Rule 408 And The Mediation-Privilege Statutes, Lynne H. Rambo

Lynne H. Rambo

Virtually all American jurisdictions have laws—either rules of evidence or mediation-privilege statutes or both—that exclude from evidence statements that parties make during negotiations and mediations. The legislatures (and sometimes courts) that have adopted these exclusionary rules have invoked a public policy rationale: that parties must be able to speak freely to settle disputes, and they will not speak freely if their statements during negotiation can later be admitted against them. This rationale is so widely revered that many courts have relied on it to prohibit the use of negotiation statements to impeach, even when the inconsistency of the negotiation statement …

Much Uncertainty About Uncertain Tax Positions, Robert D. Probasco

Robert Probasco

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 …

Limited Admissibility And Its Limitations, Lisa Dufraimont

Lisa Dufraimont

Among the challenges facing juries and judges in adjudicating cases is the obligation to use evidence for limited purposes. Evidence inadmissible for one purpose is frequently admissible for other purposes, a situation known as "limited admissibility". Where limited admissibility arises in jury trials, courts generally deliver limiting instructions outlining the inferences that can legitimately be drawn from the evidence and identifying prohibited lines of reasoning to be avoided. Limiting instructions represent an expedient solution to limited-admissibility problems, but they create obvious problems of their own. A thoughtful observer might suspect-as psychological studies confirm-that limiting instructions are likely to fail in …

Realizing The Potential Of The Principled Approach To Evidence, Lisa Dufraimont

Lisa Dufraimont

Ron Delisle's concern that lawyers and judges be constantly mindful of the purposes and policies underlying the rules of evidence led him to become one of the pioneers of the principled approach to evidence. This paper seeks to evaluate the extent to which the efforts of Canadian courts to incorporate principles into evidence law have alleviated the problem of the complexity of the traditional rules. Evidentiary rules are complex because they are dense or technical. Evidentiary principles are more capable of flexible and contextual application than evidentiary rules, but principles too are complex in the sense that they are less …

Self Incrimination And Cryptographic Keys, Gregory S. Sergienko

Greg Sergienko

Modern cryptography can make it virtually impossible to decipher documents without the cryptographic key thus making the availability of the contents of those documents depend on the availability of the key. This article examines the Fourth and Fifth Amendments' protection against the compulsory production of the key and the scope of the Fifth Amendment immunity against compelled production. After analyzing these questions using prevailing Fourth and Fifth Amendment jurisprudence, I shall describe the advantages of a privacy-based approach in practical and constitutional terms.

The Grand Jury: A Shield Of A Different Sort, R. Michael Cassidy, Julian A. Cook Iii

R. Michael Cassidy

According to the Washington Post, 991 people were shot to death by police officers in the United States during calendar year 2015, and 957 people were fatally shot in 2016. A disproportionate percentage of the citizens killed in these police-civilian encounters were black. Events in Ferguson, Missouri; Chicago, Illinois; Charlotte, North Carolina; Baton Rouge, Louisiana; and Staten Island, New York - to name but a few affected cities - have now exposed deep distrust between communities of color and law enforcement. Greater transparency is necessary to begin to heal this culture of distrust and to inform the debate going forward …

Using Prior Consistent Statements To Rehabilitate Credibility Or To Prove Substantive Assertions Before And After The 2014 Amendment Of Federal Rule Of Evidence 801(D)(1)(B), Floralynn Einesman

Floralynn Einesman

The Federal Rules of Evidence (FRE) expanded the non-hearsay category of admissible prior consistent statements with FRE 801(d)(1)(B)(ii) to include any statements counsel uses to rehabilitate a declarant’s credibility after that credibility has been attacked. FREV 801(d)(1)(B)(i) and (ii) require that a declarant testify and be subjected to cross-examination about the prior consistent statement. Under these rules, the time at which the declarant made the consistent statement and her reason for making it are critical.

When the declarant does not testify, however, under FRE 806 opposing counsel may still attack the declarant’s credibility. Under these circumstances, it is often challenging …

An Evidentiary Oddity: “Careful Habit” – Does The Law Of Evidence Embrace This Archaic/Modern Concept?, 43 Ohio N.U. L. Rev. 293 (2017), Marc Ginsberg

Marc D. Ginsberg

The concept of the “careful habit”[i] is intriguing. The law of evidence vigorously distinguishes between character evidence (largely inadmissible)[ii] and habit evidence (presumptively admissible).[iii] Character is understood as a propensity to act in a certain fashion[iv]—a person’s disposition. Habit is understood as non-volitional, repetitive specific conduct, in response to stimuli, over a rather lengthy period of time.[v] “Carefulness” is known by the law as a character trait.[vi] Carefulness should not be confused with habit, yet this confusion has occurred in multiple jurisdictions, many years ago and recently. This paper seeks to explore the development of the curious and anomalous concept …
