Bending The Rules Of Evidence, Edward K. Cheng, G. Alexander Nunn, Julia Simon-Kerr

Northwestern University Law Review

The evidence rules have well-established, standard textual meanings—meanings that evidence professors teach their law students every year. Yet, despite the rules’ clarity, courts misapply them across a wide array of cases: Judges allow past acts to bypass the propensity prohibition, squeeze hearsay into facially inapplicable exceptions, and poke holes in supposedly ironclad privileges. And that’s just the beginning.

The evidence literature sees these misapplications as mistakes by inept trial judges. This Article takes a very different view. These “mistakes” are often not mistakes at all, but rather instances in which courts are intentionally bending the rules of evidence. Codified evidentiary …

The Evidentiary Implications Of Interpreting Black-Box Algorithms, Varun Bhatnagar

Northwestern Journal of Technology and Intellectual Property

Biased black-box algorithms have drawn increasing levels of scrutiny from the public. This is especially true for those black-box algorithms with the potential to negatively affect protected or vulnerable populations.1 One type of these black-box algorithms, a neural network, is both opaque and capable of high accuracy. However, neural networks do not provide insights into the relative importance, underlying relationships, structures of the predictors or covariates with the modelled outcomes.2 There are methods to combat a neural network’s lack of transparency: globally or locally interpretable post-hoc explanatory models.3 However, the threat of such measures usually does not bar an actor …

Artificial Intelligence As Evidence, Paul W. Grimm, Maura R. Grossman, Gordon V. Cormack

Northwestern Journal of Technology and Intellectual Property

This article explores issues that govern the admissibility of Artificial Intelligence (“AI”) applications in civil and criminal cases, from the perspective of a federal trial judge and two computer scientists, one of whom also is an experienced attorney. It provides a detailed yet intelligible discussion of what AI is and how it works, a history of its development, and a description of the wide variety of functions that it is designed to accomplish, stressing that AI applications are ubiquitous, both in the private and public sectors. Applications today include: health care, education, employment-related decision-making, finance, law enforcement, and the legal …

Innovating Criminal Justice, Natalie Ram

Northwestern University Law Review

From secret stingray devices that can pinpoint a suspect’s location, to advanced forensic DNA-analysis tools, to recidivism risk statistic software—the use of privately developed criminal justice technologies is growing. So too is a concomitant pattern of trade secret assertion surrounding these technologies. This Article charts the role of private law secrecy in shielding criminal justice activities, demonstrating that such secrecy is pervasive, problematic, and ultimately unnecessary for the production of well-designed criminal justice tools.

This Article makes three contributions to the existing literature. First, the Article establishes that trade secrecy now permeates American criminal justice, shielding privately developed criminal justice …

Gatekeeping Science: Using The Structure Of Scientific Research To Distinguish Between Admissibility And Weight In Expert Testimony, David L. Faigman, Christopher Slobogin, John Monahan

Northwestern University Law Review

Fundamental to all evidence rules is the division of responsibility between the judge, who determines the admissibility of evidence, and the jury, which gauges its weight. In most evidentiary contexts, such as those involving hearsay and character, threshold admissibility obligations are clear and relatively uncontroversial. The same is not true for scientific evidence. The complex nature of scientific inference, and in particular the challenges of reasoning from group data to individual cases, has bedeviled courts. As a result, courts vary considerably on how they define the judge’s gatekeeping task under Federal Rule of Evidence 702 and its state equivalents.

Forced Decryption As Equilibrium—Why It’S Constitutional And How Riley Matters, Dan Terzian

Northwestern University Law Review

This Essay considers whether the government can force a person to decrypt his computer. The only courts to consider the issue limited their analyses to rote application of predigital doctrine and dicta. This is a mistake; courts should instead aim to maintain the ex ante equilibrium of privacy and government power. This approach—seeking equilibrium—was just endorsed by the Supreme Court in Riley v. California, a recent Fourth Amendment case. Yet Riley’s rationale also extends to the Fifth Amendment’s Self-Incrimination Clause, and maintaining equilibrium there requires permitting forced decryption. Because current doctrine can be interpreted as allowing forced decryption, …

Trial By Google: Judicial Notice In The Information Age, Jeffrey Bellin, Andrew Guthrie Ferguson

Northwestern University Law Review

This Article presents a theory of judicial notice for the information age. It argues that the ease of accessing factual data on the Internet allows judges and litigants to expand the use of judicial notice in ways that raise significant concerns about admissibility, reliability, and fair process. State and federal courts are already applying the surprisingly pliant judicial notice rules to bring websites ranging from Google Maps to Wikipedia into the courtroom, and these decisions will only increase in frequency in coming years. This rapidly emerging judicial phenomenon is notable for its ad hoc and conclusory nature—attributes that have the …

High Expectations And Some Wounded Hopes: The Policy And Politics Of A Uniform Statute On Videotaping Custodial Interrogations, Andrew E. Taslitz

Northwestern Journal of Law & Social Policy

Much has been written about the need to videotape the entire process of police interrogation of suspects. Videotaping discourages abusive interrogation techniques, improves police training in proper techniques, reduces frivolous suppression motions, and improves jury decision making about the voluntariness and accuracy of a confession. Despite these benefits, only a small number of states have adopted legislation mandating electronic recording of the entire interrogation process. In the hope of accelerating legislative adoption of this procedure and of improving the quality of such legislation, the Uniform Law Commission (ULC) ratified a uniform recording statute for consideration by the states. I was …
