Predicting Less, Understanding More: Shifting The Use Of Machine Learning From Individual Prediction To Structural Insights In Systems That Affect Children And Families, Amanda J. Fairchild, Joshua Gupta-Kagan, Andrew Barclay

Faculty Scholarship

Machine learning algorithms have been deeply embedded across domains, valued for their capacity to analyze large-scale data and to support a range of descriptive and predictive tasks. Despite their versatility, most applications to date have focused on individual-level prediction at the expense of broader structural insights. This paper shifts that focus by using comprehensive demographic, juvenile justice, and other key data from child-serving agencies in one southern state to examine how juvenile and family court intake structures shape case outcomes in delinquency referrals. Specifically, we combine machine learning algorithms with a doubly robust, potential outcomes-based modeling procedure to estimate the …

Ai Suppression: E-Discovery Software And Brady, Jason Hartline, Liren Shan, Alec Sun, Rebecca Wexler

Faculty Scholarship

Prosecutors regularly rely on AI e-discovery software, known as technology assisted review (TAR) tools, to sort and prioritize digital evidence. These tools implicate constitutional concerns: they can either risk suppressing or help to surface exculpatory and impeachment evidence that prosecutors must disclose under the Brady due process rule. Yet doctrine, agency guidance, and scholarship offer virtually no direction on their use.

This Article examines how TAR affects Brady compliance. Using computer science simulations on synthetic data sets, we show that TAR can either hide or help to expose Brady evidence, depending on how it is configured and the configurations of …

Metrics Not Thresholds: How To Regulate Ai And Other Expert Methods For Use In Criminal Investigations And Proceedings, Rebecca Wexler

Faculty Scholarship

Should regulators set performance thresholds for AI tools used in the criminal legal system? This Article draws on U.S. evidence law for guidance. Its answer is ... don’t. Instead of gatekeeping with ex ante performance thresholds, regulators should require or incentivize metrics of reliability that can be clearly communicated to end-user decisionmakers.

Drug War Repairs Guarantees, Amber Baylor

Faculty Scholarship

Drug legalization, especially cannabis legalization, is a critical step forward in states’ willingness to address systemic disparities, privacy intrusions, violence, and other harms of the drug war. Yet, reforms center on legalization and repair through a narrow lens, focused on changes to the penal code. The public has found that narrow forms of legalization cannot serve their purported reparative purpose. Narrowly drawn legalization is illusory. Drug war harms and punishment for legalized substance use continue. Legalization reforms are vulnerable to political trends, resulting in rollback and retrenchment of drug war operations.

Legalization cannot deliver on its reparative terms without guarantees. …

Uncomfortably Reminiscent: Odonnell V. Harris County In History And Memory, Kellen R. Funk

Faculty Scholarship

In ODonnell v. Harris County, a federal trial court enjoined the misdemeanor bail system of Houston, Texas, freeing approximately 20,000 indigent defendants annually. To do this, the trial court drew upon Reconstruction era precedents establishing intensive federal oversight of state criminal proceedings. The court explicitly invoked the Civil War and Reconstruction transformation of the federal judiciary, comparing the County’s defenses to slavery era arguments. Conversely, when the en banc Fifth Circuit reviewed a similar order in Dallas, Texas, six years later, it rejected this historical framework, condemning such litigation as an impermissible “ongoing federal audit of state criminal proceedings.” …

Evidence And Assessing Verbatim Transcription Quality Of Black English And Standard American English, L. Alexander Walker Iii

Faculty Scholarship

This chapter explores the accuracy of private transcription services when transcribing Black English and Standard American English. Courts and lawyers in the US regularly rely on transcripts from such services, but third-party verification of their accuracy, especially with respect to their quality when faced with nonstandard language varieties, is lacking. This study draws on experimental methods to contrast the quality of transcription services offered by transcribers and AI route. The quantitative results show that transcription by humans and AI resulted in more mistakes when transcribing Black English than when transcribing Standard American English. Furthermore, a qualitative analysis reveals that these …

Law Enforcement Privilege, Rebecca Wexler

Faculty Scholarship

You can’t question a secret you haven’t been told. The criminal legal system depends on fair and open proceedings to expose and regulate unlawful and unconstitutional police conduct through the courts. If police can use claims of secrecy to systematically thwart criminal defendants’ access to evidence, judicial review will fail. And yet that is exactly what is happening under a common-law doctrine called the “law enforcement privilege.” The privilege empowers police and prosecutors to rely on the results of secret investigative methods while withholding information from the defense about how those methods work. It risks perpetuating unconstitutional conduct, enabling wrongful …

The Influence Of The Race Of Defendant And The Race Of Victim On Capital Charging And Sentencing In California, Catherine M. Grosso, Jeffrey A. Fagan, Michael Laurence

Faculty Scholarship

The California Racial Justice Act of 2020 recognized racial and ethnic discrimination as a basis for relief in capital cases, expressly permitting several types of statistical evidence to be introduced. This statewide study of the influence of race and ethnicity on the application of capital punishment contributes to this evidence. We draw on data from over 27,000 murder and manslaughter convictions in California state courts between 1978 and 2002. Using multiple methods, we found significant racial and ethnic disparities in charging and sentencing decisions. Controlling for defendant culpability and specific statutory aggravators, we show that Black and Latinx defendants and …

Bail At The Founding, Kellen R. Funk, Sandra G. Mayson

Faculty Scholarship

How did criminal bail work in the Founding era? This question has become pressing as bail, and bail reform, have attracted increasing attention, in part because history is thought to bear on the meaning of bail-related constitutional provisions. To date, however, there has been no thorough account of bail at the Founding. This Article begins to correct the deficit in our collective memory by describing bail law and practice in the Founding era, from approximately 1790 to 1810. In order to give a full account, we surveyed a wide range of materials, including Founding-era statutes, case law, legal treatises, and …

Life, Liberty, And Data Privacy: The Global Cloud, The Criminally Accused, And Executive Versus Judicial Compulsory Process Powers, Rebecca Wexler

Faculty Scholarship

U.S. policymakers’ responses to a wave of global data privacy laws are creating a deep structural unfairness in the criminal legal system. In an era of cloud computing, when data about communications and activities occurring anywhere in the world can be stored on servers located anywhere else, access to such data can make the difference between convictions and acquittals. At the same time, new global data privacy laws risk cutting off cross-border access to digital evidence in criminal investigations. Recognizing the threat to law enforcement interests, U.S. policymakers enacted the CLOUD Act of 2018 to create special procedures for law …

The (Immediate) Future Of Prosecution, Daniel C. Richman

Faculty Scholarship

Even as others make cogent arguments for diminishing the work of prosecutors, work remains – cases that must be brought against a backdrop of existing economic inequality and structural racism and of an array of impoverished institutional alternatives. The (immediate) future of prosecution requires thoughtful engagement with these tragic circumstances, but it also will inevitably involve the co-production of sentences that deter and incapacitate. Across-the-board sentencing discounts based on such circumstances are no substitute for the thoughtful intermediation that only the courtroom working group – judges, prosecutors and defense counsel- can provide. The (immediate) future also requires prosecutors to do …

Unexceptional Protest, Amber Baylor

Faculty Scholarship

Anti-protest legislation is billed as applying only in the extreme circumstances of mass-movements and large scale civil disobedience. Mass protest exceptionalism provides justification for passage of anti-protest laws in states otherwise hesitant to expand public order criminal regulation. Examples include a Virginia bill that heightens penalties for a “failure to disperse following a law officer’s order”; a Tennessee law directing criminal penalties for “blocking traffic”; a bill in New York criminalizing “incitement to riot by nonresidents.” These laws might be better described as antiprotest expansions of public order legislation.

While existing critiques of these laws emphasize the chilling effects on …

Ignorance Of The Rules Of Omission: An Essay On Privilege Law, Rebecca Wexler

Faculty Scholarship

Evidentiary privileges--that is, rules that empower people to withhold evidence from legal proceedings-are one thread in a mesh of secrecy powers that control the flow of information in society. They are part and parcel of the laws, rules, norms, and practicalities that determine who can conceal and who can compel, that allocate power based on access to knowledge and its opposite. Despite the significance of privileges and of the harms that they produce, our understanding of this body of law has profound gaps.5 The questions posed above turn out to be more challenging than they might at first appear. Notwithstanding …

The Crime Of Sedition: At The Crossroads Of Reform And Resurgence, Adam M. Smith, Charlene Yim, Marryum Kahloon, Human Rights Institute

Human Rights Institute

The offense of “sedition” — often characterized as criminalizing the incitement of rebellion against the government — is an archaic crime that is frequently used to target political speech. Introduced in the sixteenth century in England specifically to suppress dissent, sedition laws spread through the British colonies. These laws still persist in some legal systems, and while there are reforms underway in some of those jurisdictions, in a few outliers, the offense continues to be prosecuted — and in some there has been a resurgence in cases.

Sedition laws have been criticized by the United Nations (“U.N.”), human rights experts, …

Socialist Republic Of Vietnam V. Pham Thi Doan Trang, David Mccraw, Human Rights Institute

Human Rights Institute

On the night of October 6, 2020, at the conclusion of a virtual human rights meeting between the governments of the United States of America and Vietnam, Vietnamese police arrested the journalist and human rights activist Pham Thi Doan Trang at her home in Hanoi. Ms. Trang was arrested and detained for allegedly “conducting propaganda against the Socialist Republic of Vietnam” and “making, storing, spreading information, materials, items for the purpose of opposing the State of Socialist Republic of Vietnam” — two of the most notorious of Vietnam’s fifteen national security offenses.

It would be a full year — during …

Getting To Death: Race And The Paths Of Capital Cases After Furman, Jeffrey A. Fagan, Garth Davies, Ray Paternoster

Faculty Scholarship

Decades of research on the administration of the death penalty have recognized the persistent arbitrariness in its implementation and the racial inequality in the selection of defendants and cases for capital punishment. This Article provides new insights into the combined effects of these two constitutional challenges. We show how these features of post-Furman capital punishment operate at each stage of adjudication, from charging death-eligible cases to plea negotiations to the selection of eligible cases for execution and ultimately to the execution itself, and how their effects combine to sustain the constitutional violations first identified 50 years ago in Furman …

Law Enforcement Organization Relationships With Prosecutors, Daniel C. Richman

Faculty Scholarship

Although police departments and prosecutor’s o􀁽ces must closely collaborate, their organizational roles and networks, and the distinctive perspectives of their personnel, will inevitably and regularly lead to forceful dialogue and disruptive friction. Such friction can occasionally undermine thoughtful deliberation about public safety, the rule of law, and community values. Viewed more broadly, however, these interactions promote just such deliberation, which will become even healthier when the dialogue breaks out of the closed world of criminal justice bureaucracies and includes the public to which these bureaucracies are ultimately responsible. This chapter explores such organizational interactions and their value.

Beyond "Children Are Different": The Revolution In Juvenile Intake And Sentencing, Joshua Gupta-Kagan

Faculty Scholarship

For more than 120 years, juvenile justice law has not substantively defined the core questions in most delinquency cases — when should the state prosecute children rather than divert them from the court system (the intake decision), and what should the state do with children once they are convicted (the sentencing decision)? Instead, the law has granted certain legal actors wide discretion over these decisions, namely prosecutors at intake and judges at sentencing. This Article identifies and analyzes an essential reform trend changing that reality: legislation, enacted in at least eight states in the 2010s, to limit when children can …

Privacy Asymmetries: Access To Data In Criminal Defense Investigations, Rebecca Wexler

Faculty Scholarship

This Article introduces the phenomenon of “privacy asymmetries,” which are privacy statutes that permit courts to order disclosures of sensitive information when requested by law enforcement but not when requested by criminal defense counsel. In the U.S. adversarial criminal legal system, defense counsel are the sole actors tasked with investigating evidence of innocence. Law enforcement has no constitutional, statutory, or formal ethical duty to seek out evidence of innocence. Therefore, statutes that selectively suppress defense investigations selectively suppress evidence of innocence. Privacy asymmetries form a recurring, albeit previously unrecognized, pattern in privacy statutes. They likely arise from legislative oversight and …

The Practice And Pedagogy Of Carceral Abolition In A Criminal Defense Clinic, Nicole Smith Futrell

Faculty Scholarship

Current social and racial justice movements have helped to advance deeper interest in the long-standing work of carceral abolitionists. Abolitionists understand that the criminal legal process ineffectively uses state-sanctioned violence, surveillance, punishment, and exclusion to address, and counterproductively perpetuate, the underlying problems that produce violence and harmful behavior in our communities. Abolition focuses on dismantling our current carceral systems and finding completely new, restorative, and collaborative ways of addressing harmful social behaviors. While abolitionist thought has long existed in organizing and non-legal academic spaces, law students and legal scholars are increasingly considering how a carceral abolitionist perspective can inform legal …

Constructing Countervailing Power: Law And Organizing In An Era Of Political Inequality, Kate Andrias

Faculty Scholarship

This Article proposes an innovative approach to remedying the crisis of political inequality: using law to facilitate organizing by the poor and working class, not only as workers, but also as tenants, debtors, welfare beneficiaries, and others. The piece draws on the social-movements literature, and the successes and failures of labor law, to show how law can supplement the deficient regimes of campaign finance and lobbying reform and enable lower-income groups to build organizations capable of countervailing the political power of the wealthy. As such, the Article offers a new direction forward for the public-law literature on political power and …

Populist Prosecutorial Nullification, Kerrel Murray

Faculty Scholarship

No one doubts that prosecutors may sometimes decline prosecution notwithstanding factual guilt. Everyone expects prosecutors to prioritize enforcement based on resource limitation and, occasionally, to decline prosecution on a case-by-case basis when they deem justice requires it. Recently, however, some state prosecutors have gone further, asserting the right to refuse categorically to enforce certain state laws. Examples include refusals to seek the death penalty and refusals to prosecute prostitution or recreational drug use. When may a single actor render inert her state’s democratically enacted law in this way? If the answer is anything other than “never,” the vast reach of …

Design Justice In Municipal Criminal Regulation, Amber Baylor

Faculty Scholarship

This article explores design justice as a framework for deeper inclusion in municipal criminal court reform. Section I provides a brief summary of a typical litigant’s path through modern municipal courts. Then, section I explores the historic role of municipal courts, the insider/outsider dichotomy of municipal criminal regulation, and the limitations of past reform efforts. Section II shifts into an overview of participatory design and discusses the new emergence of design justice. Within the discussion of design justice, the article focuses on three precepts of design justice: excavating the history and impact of the courts, creating tools for participation, and …

Thailand V. Does 1-5 Of The Organization For Thai Federation, Human Rights Institute, Demetra Sorvatzioti

Human Rights Institute

From November 2019 to January 2020, the Human Rights Clinic at Columbia Law School monitored the trial of five individuals on charges of sedition and membership in a secret society, the latter predicated on the defendants’ alleged affiliation with the Organization for Thai Federation (OTF), an organization whose political platform includes changing the existing political system from a constitutional monarchy to republicanism. Specifically, the defendants were accused of a range of nonviolent activities in support of OTF, from distributing flyers and t-shirts to communicating with other supporters of OTF — all activities protected by their right to freedom of expression …

Turkey Vs. Ahmet Tuna Altınel, René Provost, Human Rights Institute

Human Rights Institute

Ahmet Tuna Altınel is a Professor of Mathematics at the University of Lyon-1 in France. During a visit to Turkey, his passport was seized. When he inquired as to its whereabouts, he was arrested on suspicion of “propaganda for a terrorist organization,” soon thereafter charged with “membership in a terrorist organization,” and detained for nearly three months. The predicate for this charge was social media posts inviting attendance at an event in France entitled “Cizre — the Story of a Massacre” and interpretation assistance Mr. Altınel provided at the event. After his eventual release from pre-trial detention, the prosecution again …

Government Of Thailand & Chaiwat Limlikhitaksorn V. Wuth Boonlert & Samak Donnapee, Human Rights Institute, Lionel Blackman

Human Rights Institute

In 2019, Samak Donnapee, a retired forestry officer, and Wuth Boonlert, an indigenous human rights advocate, were prosecuted and tried for criminal defamation. The charges, brought by a government officer, Chaiwat Limlikhit-aksorn, (in his private capacity) and the Public Prosecutor, relate to Facebook posts by Samak Donnapee. The Prosecution alleged that the Facebook posts suggested that government employee Chaiwat Limlikhit-aksorn owned land that unlawfully encroached onto a national park that is also traditionally indigenous land. Wuth Boonlert was accused of sharing one of these posts with no further commentary. None of the posts named Chaiwat Limlikhit-aksorn.

Chaiwat Limlikhit-aksorn, a senior …

Faculty Books

The COVID-19 crisis has ended and upended lives around the globe. In addition to killing over 160,000 people, more than 35,000 in the United States alone, its secondary effects have been as devastating. These secondary effects pose fundamental challenges to the rules that govern our social, political, and economic lives. These rules are the domain of lawyers. Law in the Time of COVID-19 is the product of a joint effort by members of the faculty of Columbia Law School and several law professors from other schools.

This volume offers guidance for thinking about some the most pressing legal issues the …

Board Compliance, John Armour, Brandon L. Garrett, Jeffrey N. Gordon, Geeyoung Min

Faculty Scholarship

What role do corporate boards play in compliance? Compliance programs are internal enforcement programs, whereby firms train, monitor and discipline employees with respect to applicable laws and regulations. Corporate enforcement and compliance failures could not be more high-profile, and have placed boards in the position of responding to systemic problems. Both case law on boards’ fiduciary duties and guidance from prosecutors suggest that the board should have a continuing role in overseeing compliance activity. Yet very little is actually known about the role of boards in compliance. This paper offers the first empirical account of public companies’ engagement with compliance …

Boynton V. Virginia And The Anxieties Of The Modern African-American Customer, Amber Baylor

Faculty Scholarship

In 1958, Bruce Boynton was arrested for ordering food in a Whites-Only diner and charged with criminal trespass. Sixty years later, African Americans continue to face arrest and threat of arrest in commercial establishments based on discriminatory trespass claims. When store owners or employees decide to exclude would-be patrons from their establishment for discriminatory reasons, both overt and implicit, they rely on the police to enforce this form of discrimination. This article considers the legacy of Boynton v. Virginia, particularly the resonance of Boynton’s unaddressed claim, that the state enforcement of discriminatory trespass allegations is an Equal Protection …

Race And Reasonableness In Police Killings, Jeffrey A. Fagan, Alexis D. Campbell

Faculty Scholarship

Police officers in the United States have killed over 1000 civilians each year since 2013. The constitutional landscape that regulates these encounters defaults to the judgments of the reasonable police officer at the time of a civilian encounter based on the officer’s assessment of whether threats to their safety or the safety of others requires deadly force. As many of these killings have begun to occur under similar circumstances, scholars have renewed a contentious debate on whether police disproportionately use deadly force against African Americans and other nonwhite civilians and whether such killings reflect racial bias. We analyze data on …
