How Practices Make Principles, And How Principles Make Rules, Mitchell N. Berman

All Faculty Scholarship

The most fundamental question in general jurisprudence concerns what makes it the case that the law has the content that it does. This article offers a novel answer. According to the theory it christens “principled positivism,” legal practices ground legal principles, and legal principles determine legal rules. This two-level account of the determination of legal content differs from Hart’s celebrated theory in two essential respects: in relaxing Hart’s requirement that fundamental legal notions depend for their existence on judicial consensus; and in assigning weighted contributory legal norms—“principles”—an essential role in the determination of legal rights, duties, powers, and permissions. Drawing …

But What Is Personalized Law?, Sandra G. Mayson

All Faculty Scholarship

In Personalized Law: Different Rules for Different People, Omri Ben-Shahar and Ariel Porat undertake to ground a burgeoning field of legal thought. The book imagines and thoughtfully assesses an array of personalized legal rules, including individualized speed limits, fines calibrated to income, and medical disclosure requirements responsive to individual health profiles. Throughout, though, the conceptual parameters of “personalized law” remain elusive. It is clear that personalized law involves more data, more machine-learning, and more direct communication to individuals. But it is not clear how deep these changes go. Are they incremental—just today’s law with better tech—or do they represent …

The Law And Economics Of Redistribution, Matthew Dimick

Journal Articles

Should legal rules be used to redistribute income? Or should income taxation be the exclusive means for reducing income inequality? This article reviews the legal scholarship on this question. First, it traces how the most widely cited argument in favor of using taxes exclusively--Kaplow & Shavell's (1994) double-distortion argument--evolved from previous debates about whether legal rules could even be redistributive and whether law and economics should be concerned exclusively with efficiency or with distribution as well. Next, it surveys the responses to the double-distortion argument. These responses appear to have had only limited success in challenging the sturdy reputation of …

Automatically Extracting Meaning From Legal Texts: Opportunities And Challenges, Kevin D. Ashley

Articles

This paper examines impressive new applications of legal text analytics in automated contract review, litigation support, conceptual legal information retrieval, and legal question answering against the backdrop of some pressing technological constraints. First, artificial intelligence (Al) programs cannot read legal texts like lawyers can. Using statistical methods, Al can only extract some semantic information from legal texts. For example, it can use the extracted meanings to improve retrieval and ranking, but it cannot yet extract legal rules in logical form from statutory texts. Second, machine learning (ML) may yield answers, but it cannot explain its answers to legal questions or …

Laws, Norms, And The Institutional Analysis And Development Framework, Daniel H. Cole

Articles by Maurer Faculty

Elinor Ostrom’s Institutional Analysis and Development (IAD) framework has been described as ‘one of the most developed and sophisticated attempts to use institutional and stakeholder assessment in order to link theory and practice, analysis and policy’. But not all elements in the framework are sufficiently well developed. This paper focuses on one such element: the ‘rules-in-use’ (a.k.a. ‘rules’ or ‘working rules’). Specifically, it begins a long-overdue conversation about relations between formal legal rules and ‘working rules’ by offering a tentative and very simple typology of relations. Type 1: Some formal legal rules equal or approximate the working rules; Type 2: …

Nature Of Rules And The Meaning Of Meaning, Kent Greenawalt

Faculty Scholarship

This essay addresses two problems in legal theory. What is the nature of rules, especially legal rules? What is the meaning of a legal rule?

My main concern is the relation between these two questions. I inquire whether a sensible view of how rules work commits one to any particular approach to meaning. For this inquiry, I focus on Frederick Schauer's illuminating treatment of rules in Playing by the Rules, which he says is linked to a particular view of meaning. I assert that the linkage is much less tight than he supposes, and that competing theories about meaning are …
