The flexibility to renegotiate can facilitate long-term contracting and thereby beneficial reliance investments and risk allocation. The prospect of modification can induce contracting parties who expect their bargaining power to improve to enter into contracts earlier and realize the advantages of longer-term relationships. Otherwise, those parties might decline to contract or delay until those opportunities realize, thereby foregoing the benefits of long-term risk allocation or reliance investments. The parties decide not only whether, but also when, to make legally binding commitments to each other. Courts should be more lenient in enforcing contract modifications that, prompted by a shift in bargaining power, may have only a redistributive effect. Parties can design under-compensatory damages that would provide a credible threat of breach ex post to facilitate ex post modification. Requiring good faith in modification (along with damages) can constrain possible holdup and protect reliance investments and risk allocation.

This Article benefited from presentations at the Harvard-Yale-Stanford Junior Faculty Forum, the Law and Society Association Annual Meeting, the 2024 Access to Justice Roundtable, the Property Worksin- Progress Workshop, the State and Local Courts Workshop, and the State and Local Government Law Workshop. Emmeline Basco provided excellent research assistance and Yi Yao provided excellent assistance with data analysis. I am very grateful to the editors of The University of Chicago Law Review for their outstanding editorial work. All errors are my own.

Eviction cases make up over a quarter of all cases filed in the federal and state civil courts and have enormous consequences for tenants, who are nearly always unrepresented by counsel. These cases overwhelmingly settle, yet settlement scholars have entirely overlooked eviction both empirically and theoretically. The Article presents results from the first empirical study of eviction settlement negotiations. The study involved rigorous analysis of an original dataset of over one thousand hand-coded settlements, observations of settlement negotiations in the hallways of housing court, and dozens of interviews. The findings demonstrate that unrepresented tenants—who make up the vast majority of tenants in the eviction system—have no meaningful influence over settlement terms. Rather, the terms are set by landlords and their attorneys. Drawing on the empirical findings and scholarship about contracts of adhesion, the Article develops the theoretical concept of “settlements of adhesion.”

The Contractualization of Disability Rights Law
Yaron Covo
Assistant Professor, Case Western Reserve University School of Law.

For helpful comments on earlier drafts, I thank Sania Anwar, Ian Ayres, Abbe Gluck, Adi Goldiner, Hanoch Dagan, Doron Dorfman, Klaas Eller, Elizabeth Emens, Jasmine Harris, Avery Katz, Craig Konnoth, Juliet Kostritsky, Shirley Lin, Daniel Markovits, Petros Mavroidis, Jamelia Morgan, Szymon Osmola, David Pozen, Jessica Roberts, Emily Rock, Elle Rothermich, Kate Sapirstein, Ani Satz, Michael Ashley Stein, Karen Tani, and Cristina Tilley, as well as participants in the Junior Scholars Conference at Northeastern School of Law (2024), the Junior Faculty Forum at Richmond School of Law (2024), the 47th Health Law Professors Conference (2024), and the Ninth Annual Health Law Works-in-Progress Retreat at Seton Hall Law School (2025). Lastly, I thank the editors of The University of Chicago Law Review for their insightful and helpful edits and suggestions.

In this Article, Yaron Covo argues that disability rights law in the United States is shaped not only by civil rights statutes but also by contract law doctrines. Contract law surfaces in the disability rights context through judicial determinations of accommodations negotiations and spending clause language in disability rights statutes. The Article argues that this intertwining has eroded rights under statutes meant to promote equality and protect vulnerable classes. The Article concludes with two recommendations: replacing the “individualized” negotiation model with a uniform model and adding certain mandatory rules and defaults in the disability rights context.

On FRAND-ly Terms: Examining the Role of Juries in Standard-Essential Patent Disputes
Marta Krason
B.S., Massachusetts Institute of Technology; M.S., Stanford University; J.D. Candidate 2026, The University of Chicago Law School.

I would like to thank Professor Jonathan Masur and the editors and staff of The University of Chicago Law Review, including Andy Wang, Zoë Ewing, Jonah Klausner, Karan Lala, Eric Haupt, Eugene DeCosse, and Helen Chamberlin, for their thoughtful advice and insights.

Holders of patents covering technology standards, known as standard-essential patents (SEP), control the rights to an invention with no commercially-viable alternative or that cannot be designed around while still complying with a standard. This gives SEP holders significant leverage in licensing negotiations. Standards development organizations (SDOs) play an important role in curbing opportunistic behavior by patent holders. SDOs require SEP holders to license their patents on fair, reasonable, and non-discriminatory (FRAND) terms. However, courts have mischaracterized FRAND commitments, concluding that these disputes carry a Seventh Amendment guarantee to a jury trial. This mischaracterization undermines the fair resolution of FRAND disputes, and a different approach is necessary. In this Comment, Marta Krason proposes an alternative analytical framework that more accurately characterizes FRAND disputes by drawing on principles from contract and property law, concluding that the constitutionally proper adjudicator is a judge, not a jury.

Critics of the criminal enforcement system have condemned the expansion and privatization of electronic monitoring, criminal diversion, parole, and probation. But the astonishing perversion of contract involved in these new practices has gone unnoticed. Though incarceration-alternative (IA) contracting is sometimes framed as humane, historical and current context illuminates its coercive nature. IA contracting must be examined under classical contract theory and in light of the history of economic exploitation using criminal enforcement power harnessed to contract, including in the racial peonage system under Jim Crow. This Article documents this systematic underregulation through the first empirical study of legal regimes for IA contracts. To the extent that the theoretical limits of contract are not presently reflected in the common law of contract, regulatory reforms that better regulate seller and government practices might reduce the risk of exploitation.

Essay
A Story of Two Holy Grails: How Artificial Intelligence Will Change the Design and Use of Corporate Insolvency Law
Felix Steffek
Felix Steffek is Professor of Law at the University of Cambridge. He serves as Director of the Centre for Corporate and Commercial Law (3CL) and holds a JM Keynes Fellowship in Financial Economics. He is Global Distinguished Professor of Law at the University of Notre Dame, SGRI Visiting Professor at Singapore Management University, and Senior Member of Newnham College.

The author is grateful for the very helpful comments received at the conference on ‘How AI Will Change the Law’ organized by the University of Chicago Coase-Sandor Institute for Law and Economics, the University of Chicago Law Review, and the Oxford Business Law Blog, in particular from Tony Casey who contributed a formal comment.

This Essay explores the two holy grails of AI and the law: predicting court decisions and predicting contracts. While there is some overlap between the two, because in order to draft contracts one needs to know the law, both issues can be functionally distinguished. These two areas, and their importance in the context of increasing AI development, are explored more deeply within the context of corporate insolvency law.

Contractual Evolution

Conventional wisdom portrays contracts as static distillations of parties’ shared intent at some discrete point in time. In reality, however, contract terms evolve in response to their environments, including new laws, legal interpretations, and economic shocks. While several legal scholars have offered stylized accounts of this evolutionary process, we still lack a coherent, general theory that broadly captures the dynamics of real-world contracting practice. This paper advances such a theory, in which the evolution of contract terms is a byproduct of several key features, including efficiency concerns, information, and sequential learning by attorneys who negotiate several deals over time.

I thank Saul Levmore for his thoughtful comments. The Frank Greenberg Fund provided generous research support for this Essay.
