Enhanced Public Defense Improves Pretrial Outcomes And Reduces Racial Disparities, Paul S. Heaton Apr 2021

Enhanced Public Defense Improves Pretrial Outcomes And Reduces Racial Disparities, Paul S. Heaton

All Faculty Scholarship

Numerous jurisdictions are working to reform pretrial processes to reduce or eliminate money bail and decrease pretrial detention. Although reforms such as the abandonment of bail schedules or adoption of actuarial risk assessment tools have been widely enacted, the role of defense counsel in the pretrial process has received less attention.

This Article considers an approach to pretrial reform focused on improving the quality of defense counsel. In Philadelphia, a substantial fraction of people facing criminal charges are detained following rapid preliminary hearings where initial release conditions are set by bail magistrates operating with limited information. Beginning in 2017, the …


Class Certification In The U.S. Courts Of Appeals: A Longitudinal Study, Stephen B. Burbank, Sean Farhang Jan 2021

Class Certification In The U.S. Courts Of Appeals: A Longitudinal Study, Stephen B. Burbank, Sean Farhang

All Faculty Scholarship

There is a vast literature on the modern class action, but little of it is informed by systematic empirical data. Mindful both that there have been few Supreme Court class certification decisions and that they may not provide an accurate picture of class action jurisprudence, let alone class action activity, over time, we created a comprehensive data set of class certification decisions in the United States Courts of Appeals consisting of all precedential panel decisions addressing whether a class should be certified from 1966 through 2017, and of nonprecedential panel decisions from 2002 through 2017.

In Section I, through a …


Litigating Epa Rules: A Fifty-Year Retrospective Of Environmental Rulemaking In The Courts, Cary Coglianese, Daniel E. Walters Jan 2020

Litigating Epa Rules: A Fifty-Year Retrospective Of Environmental Rulemaking In The Courts, Cary Coglianese, Daniel E. Walters

All Faculty Scholarship

Over the last fifty years, the U.S. Environmental Protection Agency (EPA) has found itself repeatedly defending its regulations before federal judges. The agency’s engagement with the federal judiciary has resulted in prominent Supreme Court decisions, such as Chevron v. NRDC and Massachusetts v. EPA, which have left a lasting imprint on federal administrative law. Such prominent litigation has also fostered, for many observers, a longstanding impression of an agency besieged by litigation. In particular, many lawyers and scholars have long believed that unhappy businesses or environmental groups challenge nearly every EPA rule in court. Although some empirical studies have …


Boots And Bail On The Ground: Assessing The Implementation Of Misdemeanor Bail Reforms In Georgia, Andrea Woods, Sandra G. Mayson, Lauren Sudeall, Guthrie Armstrong, Anthony Potts Jan 2020

Boots And Bail On The Ground: Assessing The Implementation Of Misdemeanor Bail Reforms In Georgia, Andrea Woods, Sandra G. Mayson, Lauren Sudeall, Guthrie Armstrong, Anthony Potts

All Faculty Scholarship

This Article presents a mixed-methods study of misdemeanor bail practice across Georgia in the wake of reform. We observed bail hearings and interviewed system actors in a representative sample of fifty-five counties to assess the extent to which pretrial practice conforms to legal standards clarified in Senate Bill 407 and Walker v. Calhoun. We also analyzed jail population data published by county jails and by the Georgia Department of Community Affairs. We found that a handful of counties have made promising headway in adhering to law and best practices, but that the majority have some distance to go. Most …


American Pipe Tolling, Statutes Of Repose, And Protective Filings: An Empirical Study, David Freeman Engstrom, Jonah B. Gelbach Mar 2017

American Pipe Tolling, Statutes Of Repose, And Protective Filings: An Empirical Study, David Freeman Engstrom, Jonah B. Gelbach

All Faculty Scholarship

This paper offers a conceptual and empirical analysis of a key issue that overhangs CalPERS v. ANZ Securities, soon to be decided by the Supreme Court. In particular, the paper offers an empirical estimate of the plausible quantity of wasteful protective filings that putative class members might make if the Court were to hold that American Pipe tolling does not apply to statutes of repose in the federal securities laws.


Class Actions And The Counterrevolution Against Federal Litigation, Stephen B. Burbank, Sean Farhang Jan 2017

Class Actions And The Counterrevolution Against Federal Litigation, Stephen B. Burbank, Sean Farhang

All Faculty Scholarship

In this article we situate consideration of class actions in a framework, and fortify it with data, that we have developed as part of a larger project, the goal of which is to assess the counterrevolution against private enforcement of federal law from an institutional perspective. In a series of articles emerging from the project, we have documented how the Executive, Congress and the Supreme Court (wielding both judicial power under Article III of the Constitution and delegated legislative power under the Rules Enabling Act) fared in efforts to reverse or dull the effects of statutory and other incentives for …


Actions Speak Louder Than Images: The Use Of Neuroscientific Evidence In Criminal Cases, Stephen J. Morse Jun 2016

Actions Speak Louder Than Images: The Use Of Neuroscientific Evidence In Criminal Cases, Stephen J. Morse

All Faculty Scholarship

This invited commentary for Journal of Law & the Biosciences considers four empirical studies previously published in the journal of the reception of neuroscientific evidence in criminal cases in the United States, Canada, England and Wales, and the Netherlands. There are conceded methodological problems with all, but the data are nonetheless instructive and suggestive. The thesis of the comment is that the courts are committing the same errors that have bedeviled the reception of psychiatric and psychological evidence. There is insufficient caution about the state of the science, and more importantly, there is insufficient understanding of the relevance of the …


The Subterranean Counterrevolution: The Supreme Court, The Media, And Litigation Retrenchment, Stephen B. Burbank, Sean Farhang Jan 2016

The Subterranean Counterrevolution: The Supreme Court, The Media, And Litigation Retrenchment, Stephen B. Burbank, Sean Farhang

All Faculty Scholarship

This article is part of a larger project to study the counterrevolution against private enforcement of federal law from an institutional perspective. In a series of articles emerging from the project, we show how the Executive, Congress and the Supreme Court (wielding both judicial power under Article III of the Constitution and delegated legislative power under the Rules Enabling Act) fared in efforts to reverse or dull the effects of statutory and other incentives for private enforcement. An institutional perspective helps to explain the outcome we document: the long-term erosion of the infrastructure of private enforcement as a result of …


Can We Learn Anything About Pleading Changes From Existing Data?, Jonah B. Gelbach Jan 2015

Can We Learn Anything About Pleading Changes From Existing Data?, Jonah B. Gelbach

All Faculty Scholarship

In light of the gateway role that the pleading standard can play in our civil litigation system, measuring the empirical effects of pleading policy changes embodied in the Supreme Court's controversial Twombly and Iqbal cases is important. In my earlier paper, Locking the Doors to Discovery, I argued that in doing so, special care is required in formulating the object of empirical study. Taking party behavior seriously, as Locking the Doors does, leads to empirical results suggesting that Twombly and Iqbal have had substantial effects among cases that face Rule 12(b)(6) motions post-Iqbal. This paper responds to …


Litigating Toward Settlement, Christina L. Boyd, David A. Hoffman Jan 2013

Litigating Toward Settlement, Christina L. Boyd, David A. Hoffman

All Faculty Scholarship

Civil litigation typically ends when the parties compromise. While existing theories of settlement primarily focus on information exchange, we instead examine how motion practice, especially non-discovery motions, can substantially shape parties’ knowledge about their cases and thereby influence the timing of settlement. Using docket-level federal district court data, we find a number of strong effects regarding how motions can influence this process, including that the filing of a motion significantly speeds case settlement, that granted motions are more immediately critical to settlement timing than motions denied, and that plaintiff victories have a stronger effect than defendant victories. These results provide …
