Twenty Years After Krieger V Law Society Of Alberta: Law Society Discipline Of Crown Prosecutors And Government Lawyers, Andrew Flavelle Martin

Articles, Book Chapters, & Popular Press

Krieger v. Law Society of Alberta held that provincial and territorial law societies have disciplinary jurisdiction over Crown prosecutors for conduct outside of prosecutorial discretion. The reasoning in Krieger would also apply to government lawyers. The apparent consensus is that law societies rarely exercise that jurisdiction. But in those rare instances, what conduct do Canadian law societies discipline Crown prosecutors and government lawyers for? In this article, I canvass reported disciplinary decisions to demonstrate that, while law societies sometimes discipline Crown prosecutors for violations unique to those lawyers, they often do so for violations applicable to all lawyers — particularly …

Theorizing Corroboration, Maggie Wittlin

Faculty Scholarship

A child makes an out-of-court statement accusing an adult of abuse. That statement is important proof, but it also presents serious reliability concerns. When deciding whether it is sufficiently reliable to be admitted, should a court consider whether the child’s statement is corroborated—whether, for example, there is medical evidence of abuse? More broadly, should courts consider corroboration when deciding whether evidence is reliable enough to be admitted at trial? Judges, rule-makers, and scholars have taken significantly divergent approaches to this question and come to different conclusions.

This Article argues that there is a key problem with using corroboration to evaluate …

One Step Backward: The Ninth Circuit's Unfortunate Rule 404(B) Decision In United States V. Lague, Dora Klein

Faculty Articles

The federal courts' current approach to character evidence is widely recognized as problematic. Although Rule 404(b)(1) categorically prohibits the use of character evidence, Rule 404(b)(2) presents a list of examples of permitted purposes that has tempted courts to view the admission of other-acts evidence as proper so long as the evidence is merely relevant to a non-character purpose. Additionally, courts have misconstrued the inclusive structure of Rule 404(b) as creating a presumption

in favor of admissibility. Recent efforts to correct this mistakenly permissive view include decisions by several of the federal circuit courts of appeals recognizing that Rule 404(b) requires …

Critical Review Of The Use Of The Rorschach In European Courts, Igor Areh, Fanny Verkampt, Alfred Allan

Research outputs 2014 to 2021

In relation to the admissibility of evidence obtained using projective personality tests arose in F v. Bevándorlási és Állampolgársági Hivatam (2018). The Court of Justice of the European Union has held that an expert’s report can only be accepted if it is based on the international scientific community’s standards, but has refrained from stipulating what these standards are. It appears timely for European psychologists to decide what standards should be applied to determine whether or not a test is appropriate for psycholegal use. We propose standards and then apply them to the Rorschach because it was used in this case …

Requiring What’S Not Required: Circuit Courts Are Disregarding Supreme Court Precedent And Revisiting Officer Inadvertence In Cyberlaw Cases, Michelle Zakarin

Scholarly Works

As the age of technology has taken this country by surprise and left us with an inability to formally prepare our legal system to incorporate these advances, many courts are forced to adapt by applying pre-technology rules to new technological scenarios. One illustration is the plain view exception to the Fourth Amendment. Recently, the issue of officer inadvertence at the time of the search, a rule that the United States Supreme Court has specifically stated is not required in plain view inquiries, has been revisited in cyber law cases. It could be said that the courts interested in the existence …

Antitrust Harm And Causation, Herbert J. Hovenkamp

All Faculty Scholarship

How should plaintiffs show harm from antitrust violations? The inquiry naturally breaks into two issues: first, what is the nature of the harm? and second, what does proof of causation require? The best criterion for assessing harm is likely or reasonably anticipated output effects. Antitrust’s goal should be output as high as is consistent with sustainable competition.

The standard for proof of causation then depends on two things: the identity of the enforcer and the remedy that the plaintiff is seeking. It does not necessarily depend on which antitrust statute the plaintiff is seeking to enforce. For public agencies, enforcement …

Scientific Gerrymandering & Bifurcation, Katrina F. Kuh, Megan Edwards, Frederick A. Mcdonald

Elisabeth Haub School of Law Faculty Publications

Environmental litigation must often examine the propriety of corporate conduct in areas of scientific complexity. In the second generation of climate nuisance suits, for example, allegations of corporate participation in the climate disinformation campaign are woven into plaintiffs’ claims. Toxic tort suits, currently and most notably in the Roundup and PFAS litigation, present another area of environmental litigation grappling with the legal ramifications of alleged corporate deception about scientific information. Toxic tort suits often surface allegations, and in many cases disturbing evidence, of what we term corporate “scientific gerrymandering”— corporate efforts to finesse, slow, or even mislead scientific understanding of …

The Disruption Of Covid-19: How A Virtual World Creates Opportunity For Improvement In The Criminal Justice System’S Treatment Of Complainants Of Sexual Violence, Leah Roberston

Law in a Post-Pandemic World

This paper argues that the COVID-19 pandemic has normalized video conferencing within the legal system such that survivors ought to be able to routinely testify outside of the court environment. Though there have always been high rates of sexualized violence, the onset of the pandemic has led to increased rates of sexualized violence, which could lead to greater numbers of trials prosecuting perpetrators. However, only a small amount of complainants turn to the court as a form of justice. This is likely due to the inhumane conditions inflicted on complainants during the trial process. The pandemic has revealed that the …

“Rule Of Inclusion" Confusion, Dora Klein

Faculty Articles

Some rules of evidence are complex. The federal rules governing the admissibility of hearsay statements,' for example, include at least forty different provisions. Numerous judges and scholars have commented on the complexity of the hearsay rules. Not all rules of evidence are complex, however. For example, the federal rules governing the admissibility of character evidence are relatively straightforward: evidence that is offered for the purpose of proving character is inadmissible, subject to a few well-defined exceptions. Despite this relative straightforwardness, many of the federal circuit courts of appeals have overlaid the rules regarding character evidence particularly Rule 404(b)--with unnecessary interpretive …

Power And Statistical Significance In Securities Fraud Litigation, Jill E. Fisch, Jonah B. Gelbach

All Faculty Scholarship

Event studies, a half-century-old approach to measuring the effect of events on stock prices, are now ubiquitous in securities fraud litigation. In determining whether the event study demonstrates a price effect, expert witnesses typically base their conclusion on whether the results are statistically significant at the 95% confidence level, a threshold that is drawn from the academic literature. As a positive matter, this represents a disconnect with legal standards of proof. As a normative matter, it may reduce enforcement of fraud claims because litigation event studies typically involve quite low statistical power even for large-scale frauds.

This paper, written for …

Dispute Settlement Under The African Continental Free Trade Area Agreement: A Preliminary Assessment, Olabisi D. Akinkugbe

Articles, Book Chapters, & Popular Press

The African Continental Free Trade Area Agreement (AfCFTA) will add a new dispute settlement system to the plethora of judicial mechanisms designed to resolve trade disputes in Africa. Against the discontent of Member States and limited impact the existing highly legalized trade dispute settlement mechanisms have had on regional economic integration in Africa, this paper undertakes a preliminary assessment of the AfCFTA Dispute Settlement Mechanism (DSM). In particular, the paper situates the AfCFTA-DSM in the overall discontent and unsupportive practices of African States with highly legalized dispute settlement systems and similar WTO-Styled DSMs among other shortcomings. Notwithstanding the transplantation of …

Excessive Force: Justice Requires Refining State Qualified Immunity Standards For Negligent Police Officers, Angie Weiss

Seattle University Law Review SUpra

At the time this Note was written, there was no Washington state equivalent of the § 1983 Civil Rights Act. As plaintiffs look to the Washington state courts as an alternative to federal courts, they will find that Washington state has a different structure of qualified immunity protecting law enforcement officers from liability.

In this Note, Angie Weiss recommends changing Washington state's standard of qualified immunity. This change would ensure plaintiffs have a state court path towards justice when they seek to hold law enforcement officers accountable for harm. Weiss explains the structure and context of federal qualified immunity; compares …

The Use Of Technical Experts In Software Copyright Cases: Rectifying The Ninth Circuit’S “Nutty” Rule, Shyamkrishna Balganesh, Peter Menell

All Faculty Scholarship

Courts have long been skeptical about the use of expert witnesses in copyright cases. More than four decades ago, and before Congress extended copyright law to protect computer software, the Ninth Circuit in Krofft Television Prods., Inc. v. McDonald’s Corp., ruled that expert testimony was inadmissible to determine whether Mayor McCheese and the merry band of McDonaldland characters infringed copyright protection for Wilhelmina W. Witchiepoo and the other imaginative H.R. Pufnstuf costumed characters. Since the emergence of software copyright infringement cases in the 1980s, substantially all software copyright cases have permitted expert witnesses to aid juries in understanding software …

Confronting Memory Loss, Paul F. Rothstein, Ronald J. Coleman

Georgetown Law Faculty Publications and Other Works

The Confrontation Clause of the Sixth Amendment grants “the accused” in “all criminal prosecutions” a right “to be confronted with the witnesses against him.” A particular problem occurs when there is a gap in time between the testimony that is offered, and the cross-examination of it, as where, pursuant to a hearsay exception or exemption, evidence of a current witness’s prior statement is offered and for some intervening reason her current memory is impaired. Does this fatally affect the opportunity to “confront” the witness? The Supreme Court has, to date, left unclear the extent to which a memory-impaired witness can …

The Meaning Of A Misdemeanor In A Post-Ferguson World: Evaluating The Reliability Of Prior Conviction Evidence, John D. King

Scholarly Articles

Despite evidence that America’s low-level courts are overburdened, unreliable, and structurally biased, sentencing judges continue to uncritically consider a defendant’s criminal history in fashioning an appropriate punishment. Misdemeanor courts lack many of the procedural safeguards that are thought to ensure accuracy and reliability. As with other stages of the criminal justice system, people of color and poor people are disproportionately burdened with the inaccuracies of the misdemeanor system.

This Article examines instances in which sentencing courts have looked behind the mere fact of a prior conviction and assessed whether that prior conviction offered any meaningful insight for the subsequent sentence. …

Exporting American Discovery, Yanbai Andrea Wang

All Faculty Scholarship

This Article presents the first comprehensive study of an intriguing and increasingly pervasive practice that is transforming civil litigation worldwide: US judges now routinely compel discovery in this country and make it available for disputes and parties not before US courts. In the past decade and a half, federal courts have received and granted thousands of such discovery requests for use in foreign civil proceedings governed by different procedural rules. I call this global role played by US courts the “export” of American discovery.

This Article compiles and analyzes a dataset of over three thousand foreign discovery requests filed between …

Social Media, Venue And The Right To A Fair Trial, Leslie Y. Garfield Tenzer

Elisabeth Haub School of Law Faculty Publications

Judicial failure to recognize social media's influence on juror decision making has identifiable constitutional implications. The Sixth Amendment right to a fair trial demands that courts grant a defendant's change of venue motion when media-generated pretrial publicity invades the unbiased sensibility of those who are asked to sit in judgment. Courts limit publicity suitable for granting a defendant's motion to information culled from newspapers, radio, and television reports. Since about 2014, however, a handful of defendants have introduced social media posts to support their claims of unconstitutional bias in the community. Despite defendants' introduction of negative social media in support …

Uncovering Juror Racial Bias, Christian Sundquist

Articles

The presence of bias in the courtroom has the potential to undermine public faith in the adversarial process, distort trial outcomes, and obfuscate the search for justice. In Pena-Rodriguez v. Colorado (2017), the U.S. Supreme Court held for the first time that the Sixth and Fourteenth Amendments required post-verdict judicial inquiry in criminal cases where racial bias clearly served as a “significant motivating factor” in juror decision-making. Courts will nonetheless likely struggle in interpreting what constitutes a "clear statement of racial bias" and whether such bias constituted a "significant motivating factor" in a juror's verdict. This Article will examine how …

An Erie Approach To Privilege Doctrine., Megan M. La Belle

Scholarly Articles

This short essay considers the HannStar and Silver cases and begins a discussion of the impact that the Erie doctrine has—and, more importantly, ought to have—on privilege law. While Erie is considered by many as “one of the modern cornerstones of our federalism,” the doctrine is important too for the change it can effect through the cross pollination of ideas among tribunals. Because privilege laws reflect deliberate policy choices by legislatures and courts, the Erie doctrine arguably plays a particularly vital role in developing this area of the law.

Introduction, Shari S. Diamond, Richard O. Lempert

Articles

Experts bedeviled the legal system long before seventeenth-century Salem, when the town's good citizens relied on youthful accusers and witchcraft experts to identify the devil's servants in their midst. As in Salem, claims of expertise have often been questioned and objections raised about the bases of expert knowledge. Expertise, then and now, did not have to be based on science; but the importance of science and the testimony of scientific experts has since medieval times been woven into the fabric of the English jurisprudence that Americans inherited. In cases as long ago as 1299 we find examples of courts seeking …

A Tale Of Two Standards: Why Wyoming Courts Should Apply The Actual Substantial Evidence Standard When Reviewing Workers’ Compensation Cases, Michael C. Duff

All Faculty Scholarship

In Wyoming, as in almost all states, facts in contested workers’ compensation cases are developed within an administrative agency. When agency factual findings are challenged in court, the level of judicial deference applied to the agency is important and may be outcome determinative. Wyoming courts claim to apply the “substantial evidence” standard of review, often expressed as evidence that a “reasonable mind could accept” as supporting an agency determination. The Wyoming Supreme Court, however, also sometimes upholds workers’ compensation agency decisions that are deemed “not contrary to the overwhelming weight of the evidence.” It is unclear whether this latter formulation …

Character Flaws, Frederic Bloom

Publications

Character evidence doctrine is infected by error. It is riddled with a set of pervasive mistakes and misconceptions—a group of gaffes and glitches involving Rule 404(b)’s “other purposes” (like intent, absence of accident, and plan) that might be called “character flaws.” This Essay identifies and investigates those flaws through the lens of a single, sensational case: United States v. Henthorn. By itself, Henthorn is a tale worth telling—an astonishing story of danger and deceit, malice and murder. But Henthorn is more than just a stunning story. It is also an example and an opportunity, a chance to consider character …

The Logic And Limits Of Event Studies In Securities Fraud Litigation, Jill E. Fisch, Jonah B. Gelbach, Jonathan Klick

All Faculty Scholarship

Event studies have become increasingly important in securities fraud litigation after the Supreme Court’s decision in Halliburton II. Litigants have used event study methodology, which empirically analyzes the relationship between the disclosure of corporate information and the issuer’s stock price, to provide evidence in the evaluation of key elements of federal securities fraud, including materiality, reliance, causation, and damages. As the use of event studies grows and they increasingly serve a gatekeeping function in determining whether litigation will proceed beyond a preliminary stage, it will be critical for courts to use them correctly.

This Article explores an array of …

Bias On Trial: Toward An Open Discussion Of Racial Stereotypes In The Courtroom, Mikah K. Thompson

Faculty Works

In the 2017 case Pena-Rodriguez v. Colorado, the U.S. Supreme Court discussed several safeguards that are in place to assist the trial court in identifying racial bias among jurors. These safeguards include voir dire examination regarding racial bias, observation of juror demeanor and conduct that might demonstrate racial bias, reports of racially biased comments or actions by jurors during trial, and non-juror evidence of racial bias after trial. The Court acknowledged that these safeguards may be insufficient at times and therefore added a fifth one, holding that trial courts may review evidence suggesting that racial bias was a motivating factor …

Error Costs, Legal Standards Of Proof And Statistical Significance, Michelle Burtis, Jonah B. Gelbach, Bruce H. Kobayashi

All Faculty Scholarship

The relationship between legal standards of proof and thresholds of statistical significance is a well-known and studied phenomena in the academic literature. Moreover, the distinction between the two has been recognized in law. For example, in Matrix v. Siracusano, the Court unanimously rejected the petitioner’s argument that the issue of materiality in a securities class action can be defined by the presence or absence of a statistically significant effect. However, in other contexts, thresholds based on fixed significance levels imported from academic settings continue to be used as a legal standard of proof. Our positive analysis demonstrates how a …

Grave Crimes And Weak Evidence: Fact-Finding Evolution In International Criminal Law, Nancy Amoury Combs

Faculty Publications

International criminal courts carry out some of the most important work that a legal system can conduct: prosecuting those who have visited death and destruction on millions. Despite the significance of their work--or perhaps because of it--international courts face tremendous challenges. Chief among them is accurate fact-finding. With alarming regularity, international criminal trials feature inconsistent, vague, and sometimes false testimony that renders judges unable to assess with any measure of certainty who did what to whom in the context of a mass atrocity. This Article provides the first-ever empirical study quantifying fact-finding in an international criminal court. The study shines …
