Digital Cluster Markets, Herbert J. Hovenkamp Apr 2022

Digital Cluster Markets, Herbert J. Hovenkamp

All Faculty Scholarship

This paper considers the role of “cluster” markets in antitrust litigation, the minimum requirements for recognizing such markets, and the relevance of network effects in identifying them.

One foundational requirement of markets in antitrust cases is that they consist of products that are very close substitutes for one another. Even though markets are nearly always porous, this principle is very robust in antitrust analysis and there are few deviations.

Nevertheless, clustering noncompeting products into a single market for purposes of antitrust analysis can be valuable, provided that its limitations are understood. Clustering contributes to market power when (1) many customers …


Preliminary Damages, Gideon Parchomovsky, Alex Stein Jan 2022

Preliminary Damages, Gideon Parchomovsky, Alex Stein

All Faculty Scholarship

Historically, the law helped impecunious plaintiffs overcome their inherent disadvantage in civil litigation. Unfortunately, this is no longer the case: modern law has largely abandoned the mission of assisting the least well off. In this Essay, we propose a new remedy that can dramatically improve the fortunes of poor plaintiffs and thereby change the errant path of the law: preliminary damages. The unavailability of preliminary damages has dire implications for poor plaintiffs, especially those wronged by affluent individuals and corporations. Resource constrained plaintiffs cannot afford prolonged litigation on account of their limited financial means. Consequently, they are forced to either …


Individualizing Criminal Law’S Justice Judgments: Shortcomings In The Doctrines Of Culpability, Mitigation, And Excuse, Paul H. Robinson, Lindsay Holcomb Jan 2022

Individualizing Criminal Law’S Justice Judgments: Shortcomings In The Doctrines Of Culpability, Mitigation, And Excuse, Paul H. Robinson, Lindsay Holcomb

All Faculty Scholarship

In judging an offender’s culpability, mitigation, or excuse, there seems to be general agreement that it is appropriate for the criminal law to take into account such things as the offender’s youthfulness or her significantly low IQ. There is even support for taking account of their distorted perceptions and reasoning induced by traumatic experiences, as in battered spouse syndrome. On the other hand, there seems to be equally strong opposition to taking account of things such as racism or homophobia that played a role in bringing about the offense. In between these two clear points, however, exists a large collection …


After The Crime: Rewarding Offenders’ Positive Post-Offense Conduct, Paul H. Robinson, Muhammad Sarahne Jul 2021

After The Crime: Rewarding Offenders’ Positive Post-Offense Conduct, Paul H. Robinson, Muhammad Sarahne

All Faculty Scholarship

While an offender’s conduct before and during the crime is the traditional focus of criminal law and sentencing rules, an examination of post-offense conduct can also be important in promoting criminal justice goals. After the crime, different offenders make different choices and have different experiences, and those differences can suggest appropriately different treatment by judges, correctional officials, probation and parole supervisors, and other decision-makers in the criminal justice system.

Positive post-offense conduct ought to be acknowledged and rewarded, not only to encourage it but also as a matter of fair and just treatment. This essay describes four kinds of positive …


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 …


A Formulaic Recitation Will Not Do: Why The Federal Rules Demand More Detail In Criminal Pleading, Charles Eric Hintz Jan 2021

A Formulaic Recitation Will Not Do: Why The Federal Rules Demand More Detail In Criminal Pleading, Charles Eric Hintz

All Faculty Scholarship

When a plaintiff files a civil lawsuit in federal court, her complaint must satisfy certain minimum standards. Specifically, under the prevailing understanding of Federal Rule of Civil Procedure 8(a), a complaint must plead sufficient factual matter to state a claim to relief that is plausible on its face, rather than mere conclusory statements. Given the significantly higher stakes involved in criminal cases, one might think that an even more robust requirement would exist in that context. But in fact a weaker pleading standard reigns. Under the governing interpretation of Federal Rule of Criminal Procedure 7(c), indictments that simply parrot the …


Politics, Identity, And Pleading Decisions On The U.S. Courts Of Appeals, Stephen B. Burbank, Sean Farhang Jan 2021

Politics, Identity, And Pleading Decisions On The U.S. Courts Of Appeals, Stephen B. Burbank, Sean Farhang

All Faculty Scholarship

We report the results of an empirical study of appeals from rulings on motions to dismiss for failure to state a claim under Federal Rule of Civil Procedure 12(b)(6) after the Supreme Court’s decisions in Twombly and Iqbal. We first describe the role that pleading was intended to play in the original (1938) Federal Rules of Civil Procedure, review the Court’s decisions in Twombly and Iqbal, and offer a brief discussion of common themes in normative scholarship that is critical of Twombly and Iqbal, including the claim that they threaten to amplify ideological and subjective decision-making, particularly …


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 …


Ai In Adjudication And Administration, Cary Coglianese, Lavi M. Ben Dor Jan 2021

Ai In Adjudication And Administration, Cary Coglianese, Lavi M. Ben Dor

All Faculty Scholarship

The use of artificial intelligence has expanded rapidly in recent years across many aspects of the economy. For federal, state, and local governments in the United States, interest in artificial intelligence has manifested in the use of a series of digital tools, including the occasional deployment of machine learning, to aid in the performance of a variety of governmental functions. In this paper, we canvas the current uses of such digital tools and machine-learning technologies by the judiciary and administrative agencies in the United States. Although we have yet to see fully automated decision-making find its way into either adjudication …


Fair Questions: A Call And Proposal For Using General Verdicts With Special Interrogatories To Prevent Biased And Unjust Convictions, Charles Eric Hintz Jan 2021

Fair Questions: A Call And Proposal For Using General Verdicts With Special Interrogatories To Prevent Biased And Unjust Convictions, Charles Eric Hintz

All Faculty Scholarship

Bias and other forms of logical corner-cutting are an unfortunate aspect of criminal jury deliberations. However, the preferred verdict system in the federal courts, the general verdict, does nothing to counter that. Rather, by forcing jurors into a simple binary choice — guilty or not guilty — the general verdict facilitates and encourages such flawed reasoning. Yet the federal courts continue to stick to the general verdict, ironically out of a concern that deviating from it will harm defendants by leading juries to convict.

This Essay calls for a change: expand the use of a special findings verdict, the general …


How Medicalization Of Civil Rights Could Disappoint, Allison K. Hoffman Jul 2020

How Medicalization Of Civil Rights Could Disappoint, Allison K. Hoffman

All Faculty Scholarship

This essay reflects on Craig Konnoth’s recent Article, Medicalization and the New Civil Rights, which is a carefully crafted and thought-provoking description of the refashioning of civil rights claims into medical rights frameworks. He compellingly threads together many intellectual traditions—from antidiscrimination law to disability law to health law—to illustrate the pervasiveness of the phenomenon that he describes and why it might be productive as a tool to advance civil rights.

This response, however, offers several reasons why medicalization may not cure all that ails civil rights litigation’s pains and elaborates on the potential risks of overinvesting in medical rights-seeking. …


The Use Of Technical Experts In Software Copyright Cases: Rectifying The Ninth Circuit’S “Nutty” Rule, Shyamkrishna Balganesh, Peter Menell Jun 2020

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 …


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 …


Mitigations: The Forgotten Side Of The Proportionality Principle, Paul H. Robinson Jan 2020

Mitigations: The Forgotten Side Of The Proportionality Principle, Paul H. Robinson

All Faculty Scholarship

In the first change to the Model Penal Code since its promulgation in 1962, the American Law Institute in 2017 set blameworthiness proportionality as the dominant distributive principle for criminal punishment. Empirical studies suggest that this is in fact the principle that ordinary people use in assessing proper punishment. Its adoption as the governing distributive principle makes good sense because it promotes not only the classic desert retributivism of moral philosophers but also crime-control utilitarianism, by enhancing the criminal law’s moral credibility with the community and thereby promoting deference, compliance, acquiescence, and internalization of its norms, rather than suffering the …


Politics, Identity, And Class Certification On The U.S. Courts Of Appeals, Stephen B. Burbank, Sean Farhang Jan 2020

Politics, Identity, And Class Certification On The U.S. Courts Of Appeals, Stephen B. Burbank, Sean Farhang

All Faculty Scholarship

This Article draws on novel data and presents the results of the first empirical analysis of how potentially salient characteristics of Court of Appeals judges influence class certification under Rule 23 of the Federal Rules of Civil Procedure. We find that the ideological composition of the panel (measured by the party of the appointing president) has a very strong association with certification outcomes, with all-Democratic panels having dramatically higher rates of procertification outcomes than all-Republican panels—nearly triple in about the past twenty years. We also find that the presence of one African American on a panel, and the presence of …


Dimensions Of Delegation, Cary Coglianese Nov 2019

Dimensions Of Delegation, Cary Coglianese

All Faculty Scholarship

How can the nondelegation doctrine still exist when the Supreme Court over decades has approved so many pieces of legislation that contain unintelligible principles? The answer to this puzzle emerges from recognition that the intelligibility of any principle dictating the basis for lawmaking is but one characteristic defining that authority. The Court has acknowledged five other characteristics that, taken together with the principle articulating the basis for executive decision-making, constitute the full dimensionality of any grant of lawmaking authority and hold the key to a more coherent rendering of the Court’s application of the nondelegation doctrine. When understood in dimensional …


Our Administered Constitution: Administrative Constitutionalism From The Founding To The Present, Sophia Z. Lee Jun 2019

Our Administered Constitution: Administrative Constitutionalism From The Founding To The Present, Sophia Z. Lee

All Faculty Scholarship

This article argues that administrative agencies have been primary interpreters and implementers of the federal Constitution throughout the history of the United States, although the scale and scope of this "administrative constitutionalism" has changed significantly over time as the balance of opportunities and constraints has shifted. Courts have nonetheless cast an increasingly long shadow over the administered Constitution. In part, this is because of the well-known expansion of judicial review in the 20th century. But the shift has as much to do with changes in the legal profession, legal theory, and lawyers’ roles in agency administration. The result is that …


The Genius Of Common Law Intellectual Property, Shyamkrishna Balganesh Jan 2019

The Genius Of Common Law Intellectual Property, Shyamkrishna Balganesh

All Faculty Scholarship

Among Richard Epstein’s influential contributions to legal scholarship over the years is his writing on common law intellectual property. In it, we see Epstein’s attempt to meld the innate logic of the common law’s conceptual structure with the realities of the modern information economy. Common law intellectual property refers to different judge made causes of action that create forms of exclusive rights and privileges in intangibles, interferences with which are then rendered enforceable through private liability. In this Essay, I examine Epstein’s writing on two such doctrines: “hot news misappropriation” and “cyber-trespass”, which embraces several important ideas that modern discussions …


Certainty Versus Flexibility In The Conflict Of Laws, Kermit Roosevelt Iii Jan 2019

Certainty Versus Flexibility In The Conflict Of Laws, Kermit Roosevelt Iii

All Faculty Scholarship

Traditional choice of law theory conceives of certainty and flexibility as opposed values: increase one, and you inevitably decrease the other. This article challenges the received wisdom by reconceptualizing the distinction. Rather than caring about certainty or flexibility for their own sake, it suggests, we care about them because each makes it easier to promote a certain cluster of values. And while there may be a necessary tradeoff between certainty and flexibility, there is no necessary tradeoff between the clusters of values. It is possible to improve a choice of law system with regard to both of them. The article …


Hushing Contracts, David A. Hoffman, Erik Lampmann Jan 2019

Hushing Contracts, David A. Hoffman, Erik Lampmann

All Faculty Scholarship

The last few years have brought a renewed appreciation of the costs of nondisclosure agreements that suppress information about sexual wrongdoing. Recently passed bills in a number of states, including New York and California, has attempted to deal with such hush contracts. But such legislation is often incomplete, and many courts and commentators continue to ask if victims of harassment can sign enforceable settlements that conceal serious, potentially metastasizing, social harms. In this Article, we argue that employing the public policy doctrine, courts ought to generally refuse to enforce hush agreements, especially those created by organizations. We restate public policy …


Preserving Life By Ranking Rights, John William Draper Dec 2018

Preserving Life By Ranking Rights, John William Draper

Librarian Scholarship at Penn Law

Border walls, abortion, and the death penalty are the current battlegrounds of the right to life. We will visit each topic and more in this paper, as we consider ranking groups of constitutional rights.

The enumerated rights of the Due Process Clauses of the Fifth and Fourteenth Amendments—life, liberty, and property—merit special treatment. They have a deeper and richer history that involves ranking. Ranking life in lexical priority over liberty and property rights protects life first and maximizes safe liberty and property rights in the absence of a significant risk to life. This is not new law; aspects of it …


A General Mitigation For Disturbance-Driven Crimes?: Psychic State, Personal Choice, And Normative Inquiries, Paul H. Robinson Oct 2018

A General Mitigation For Disturbance-Driven Crimes?: Psychic State, Personal Choice, And Normative Inquiries, Paul H. Robinson

All Faculty Scholarship

It is argued here that the narrow provoked “heat of passion” mitigation available under current law ought to be significantly expanded to include not just murder but all felonies and not just “heat of passion” but potentially all mental or emotional disturbances, whenever the offender’s situation and capacities meaningfully reduce the offender’s blameworthiness for the violation. In determining eligibility for mitigation, the jury should take into account (a) the extent to which the offender was acting under the influence of mental or emotional disturbance (the psychic state inquiry), (b) given the offender’s situation and capacities, the extent to which one …


Rights And Retrenchment In The Trump Era, Stephen B. Burbank, Sean Farhang Oct 2018

Rights And Retrenchment In The Trump Era, Stephen B. Burbank, Sean Farhang

All Faculty Scholarship

Our aim in this essay is to leverage archival research, data and theoretical perspectives presented in our book, Rights and Retrenchment: The Counterrevolution against Federal Litigation, as a means to illuminate the prospects for retrenchment in the current political landscape. We follow the scheme of the book by separately considering the prospects for federal litigation retrenchment in three lawmaking sites: Congress, federal court rulemaking under the Rules Enabling Act, and the Supreme Court. Although pertinent data on current retrenchment initiatives are limited, our historical data and comparative institutional perspectives should afford a basis for informed prediction. Of course, little in …


The Federal Rules Of Inmate Appeals, Catherine T. Struve Jan 2018

The Federal Rules Of Inmate Appeals, Catherine T. Struve

All Faculty Scholarship

The Federal Rules of Appellate Procedure turn fifty in 2018. During the Rules’ half-century of existence, the number of federal appeals by self-represented, incarcerated litigants has grown dramatically. This article surveys ways in which the procedure for inmate appeals has evolved over the past 50 years, and examines the challenges of designing procedures with confined litigants in mind. In the initial decades under the Appellate Rules, the most visible developments concerning the procedure for inmate appeals arose from the interplay between court decisions and the federal rulemaking process. But, as court dockets swelled, the circuits also developed local case management …


The Subversions And Perversions Of Shadow Vigilantism, Paul H. Robinson, Sarah M. Robinson Jan 2018

The Subversions And Perversions Of Shadow Vigilantism, Paul H. Robinson, Sarah M. Robinson

All Faculty Scholarship

This excerpt from the recently published Shadow Vigilantes book argues that, while vigilantism, even moral vigilantism, can be dangerous to a society, the real danger is not of hordes of citizens, frustrated by the system’s doctrines of disillusionment, rising up to take the law into their own hands. Frustration can spark a vigilante impulse, but such classic aggressive vigilantism is not the typical response. More common is the expression of disillusionment in less brazen ways by a more surreptitious undermining and distortion of the operation of the criminal justice system.

Shadow vigilantes, as they might be called, can affect the …


Our Principled Constitution, Mitchell N. Berman Jan 2018

Our Principled Constitution, Mitchell N. Berman

All Faculty Scholarship

Suppose that one of us contends, and the other denies, that transgender persons have constitutional rights to be treated in accord with their gender identity. It appears that we are disagreeing about “what the law is.” And, most probably, we disagree about what the law is on this matter because we disagree about what generally makes it the case that our constitutional law is this rather than that.

Constitutional theory should provide guidance. It should endeavor to explain what gives our constitutional rules the contents that they have, or what makes true constitutional propositions true. Call any such account a …


Could Official Climate Denial Revive The Common Law As A Regulatory Backstop?, Mark P. Nevitt, Robert Percival Jan 2018

Could Official Climate Denial Revive The Common Law As A Regulatory Backstop?, Mark P. Nevitt, Robert Percival

All Faculty Scholarship

The Trump Administration is rapidly turning the clock back on climate policy and environmental regulation. Despite overwhelming, peer-reviewed scientific evidence, administration officials eager to promote greater use of fossil fuels are disregarding climate science. This Article argues that this massive and historic deregulation may spawn yet another wave of legal innovation as litigants, including states and their political subdivisions, return to the common law to protect the health of the planet. Prior to the emergence of the major federal environmental laws in the 1970s, the common law of nuisance gave rise to the earliest environmental decisions in U.S. history. In …


Constructive Ambiguity And Judicial Development Of Insider Trading, Jill E. Fisch Jan 2018

Constructive Ambiguity And Judicial Development Of Insider Trading, Jill E. Fisch

All Faculty Scholarship

The Texas Gulf Sulphur decision began what has become a fifty-year project of developing U.S. insider trading regulation through judicial lawmaking. During the course of that project, the courts developed a complex, fraud-based approach to determining the scope of liability. The approach has led, in many cases, to doctrinal uncertainty, a result that is reflected in the recent decisions in Newman, Salman, and Martoma.

n the face of this uncertainty, many commentators have called for a legislative solution. This article argues, however, that the true challenge of insider trading regulation is a lack of consensus about the …


Teva And The Process Of Claim Construction, Lee Petherbridge Ph.D., R. Polk Wagner Jan 2018

Teva And The Process Of Claim Construction, Lee Petherbridge Ph.D., R. Polk Wagner

All Faculty Scholarship

In Teva Pharmaceuticals USA, Inc. v. Sandoz, Inc., the Supreme Court addressed an oft-discussed jurisprudential disconnect between itself and the U.S. Court of Appeals for the Federal Circuit: whether patent claim construction was “legal” or “factual” in nature, and how much deference is due to district court decisionmaking in this area. In this Article, we closely examine the Teva opinion and situate it within modern claim construction jurisprudence. Our thesis is that the Teva holding is likely to have only very modest effects on the incidence of deference to district court claim construction but that for unexpected reasons the …


Still Living After Fifty Years: A Census Of Judicial Review Under The Pennsylvania Constitution Of 1968, Seth F. Kreimer Jan 2018

Still Living After Fifty Years: A Census Of Judicial Review Under The Pennsylvania Constitution Of 1968, Seth F. Kreimer

All Faculty Scholarship

The year 2018 marked the fiftieth anniversary of the Pennsylvania Constitution of 1968. The time seems ripe, therefore, to explore the Pennsylvania Supreme Court’s exercise of judicial review under the 1968 Pennsylvania Constitution. This Article constitutes the first such comprehensive exploration.

The Article begins with an historical overview of the evolution of the Pennsylvania Constitution, culminating in the Constitution of 1968. It then presents a census of the 372 cases in which the Pennsylvania Supreme Court has vindicated distinctive Pennsylvania Constitutional rights under the Constitution of 1968.

Analysis of these cases leads to three conclusions:

1. Exercise of independent constitutional …
