Dworkin Versus Hart Revisited: The Challenge Of Non-Lexical Determination, Mitchell N. Berman Jun 2022

Dworkin Versus Hart Revisited: The Challenge Of Non-Lexical Determination, Mitchell N. Berman

All Faculty Scholarship

A fundamental task for legal philosophy is to explain what makes it the case that the law has the content that it does. Anti-positivists say that moral norms play an ineliminable role in the determination of legal content, while positivists say that they play no role, or only a contingent one. Increasingly, scholars report finding the debate stale. This article hopes to freshen it by, ironically, revisiting what might be thought its opening round: Dworkin’s challenge to Hartian positivism leveled in The Model of Rules I. It argues that the underappreciated significance of Dworkin’s distinction between rules and principles is …


Keeping Our Distinctions Straight: A Response To “Originalism: Standard And Procedure”, Mitchell N. Berman Jan 2022

Keeping Our Distinctions Straight: A Response To “Originalism: Standard And Procedure”, Mitchell N. Berman

All Faculty Scholarship

For half a century, moral philosophers have distinguished between a “standard” that makes acts right and a “decision procedure” by which agents can determine whether any given contemplated act is right, which is to say whether it satisfies the standard. In “Originalism: Standard and Procedure,” Stephen Sachs argues that the same distinction applies to the constitutional domain and that clear grasp of the difference strengthens the case for originalism because theorists who emphasize the infirmities of originalism as a decision procedure frequently but mistakenly infer that those flaws also cast doubt on originalism as a standard. This invited response agrees …


How Practices Make Principles, And How Principles Make Rules, Mitchell N. Berman Jan 2022

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 …


Of Law And Other Artificial Normative Systems, Mitchell N. Berman Jan 2019

Of Law And Other Artificial Normative Systems, Mitchell N. Berman

All Faculty Scholarship

Different theories of law are situated within different pictures of our normative landscape. This essay aims to make more visible and attractive one picture that reflects basic positivist sensibilities yet is oddly marginalized in the current jurisprudential literature. The picture that I have in mind tries to vindicate surface appearances. It maintains that the social world is densely populated by countless normative systems of human construction (“artificial normative systems”) whose core functions are to generate and maintain norms (oughts, obligations, powers, rights, prohibitions, and the like). The norms that these systems output are conceptually independent from each other, and may …


Kennedy's Legacy: A Principled Justice, Mitchell N. Berman, David Peters Jan 2019

Kennedy's Legacy: A Principled Justice, Mitchell N. Berman, David Peters

All Faculty Scholarship

After three decades on the Court, Justice Anthony Kennedy remains its most widely maligned member. Concentrating on his constitutional jurisprudence, critics from across the ideological spectrum have derided Justice Kennedy as “a self-aggrandizing turncoat,” “an unprincipled weathervane,” and, succinctly, “America’s worst Justice.” We believe that Kennedy is not as bereft of a constitutional theory as common wisdom maintains. To the contrary, this Article argues, his constitutional decisionmaking reflects a genuine grasp (less than perfect, more than rudimentary) of a coherent and, we think, compelling theory of constitutional law—the account, more or less, that one of has introduced in other work …


For Legal Principles, Mitchell N. Berman Jun 2017

For Legal Principles, Mitchell N. Berman

All Faculty Scholarship

Most legal thinkers believe that legal rules and legal principles are meaningfully distinguished. Many jurists may have no very precise distinction in mind, and those who do might not all agree. But it is widely believed that legal norms come in different logical types, and that one difference is reasonably well captured by a nomenclature that distinguishes “rules” from “principles.” Larry Alexander is the foremost challenger to this bit of legal-theoretic orthodoxy. In several articles, but especially in “Against Legal Principles,” an influential article co-authored with Ken Kress two decades ago, Alexander has argued that legal principles cannot exist.

The Tragedy Of Justice Scalia, Mitchell N. Berman Jan 2017

The Tragedy Of Justice Scalia, Mitchell N. Berman

All Faculty Scholarship

Justice Antonin Scalia was, by the time of his death last February, the Supreme Court’s best known and most influential member. He was also its most polarizing, a jurist whom most students of American law either love or hate. This essay, styled as a twenty-year retrospective on A Matter of Interpretation, Scalia’s Tanner lectures on statutory and constitutional interpretation, aims to prod partisans on both sides of our central legal and political divisions to better appreciate at least some of what their opponents see—the other side of Scalia’s legacy. Along the way, it critically assesses Scalia’s particular brand of …


Judge Posner’S Simple Law, Mitchell N. Berman Jan 2015

Judge Posner’S Simple Law, Mitchell N. Berman

All Faculty Scholarship

The world is complex, Richard Posner observes in his most recent book, Reflections on Judging. It follows that, to resolve real-world disputes sensibly, judges must be astute students of the world’s complexity. The problem, he says, is that, thanks to disposition, training, and professional incentives, they aren’t. Worse than that, the legal system generates its own complexity precisely to enable judges “to avoid rather than meet and overcome the challenge of complexity” that the world delivers. Reflections concerns how judges needlessly complexify inherently simple law, and how this complexification can be corrected.

Posner’s diagnoses and prescriptions range widely—from the Bluebook …


Before And After: Temporal Anomalies In Legal Doctrine, Leo Katz Jan 2003

Before And After: Temporal Anomalies In Legal Doctrine, Leo Katz

All Faculty Scholarship

Legal doctrine exhibits some striking temporal anomalies, previously not much adverted to. Wrongdoing looked at before it has occurred, and after is has occurred, is apt to look very different. I take up the two key components of wrongdoing seriatim, the harm-portion and the misconduct-portion: the "damage" part and the "liability" part. We tend to look at harm in a harm-agnifying way before it has occurred, and in a harm-inimizing way afterwards. We thus tend to think about negligence and the harm it wreaks in seemingly inconsistent ways. I examine and reject some possible explanations of this. Misconduct too looks …
