Dualism And Doctrine, Alex Stein, Dov Fox

Alex Stein

What kinds of harm among those that tortfeasors inflict are worthy of compensation? Which forms of self-incriminating evidence are privileged against government compulsion? What sorts of facts constitute a criminal defendant’s intent? Existing doctrine pins the answer to all of these questions on whether the injury, facts, or evidence at stake are “mental” or “physical.” The assumption that operations of the mind are meaningfully distinct from those of the body animates fundamental rules in our law.

A tort victim cannot recover for mental harm on its own because the law presumes that he is able to unfeel any suffering arising …

The New Doctrinalism: Implications For Evidence Theory, Alex Stein

Alex Stein

This Article revisits and refines the organizing principles of evidence law: case specificity, cost minimization, and equal best. These three principles explain and justify all admissibility and sufficiency requirements of the law of evidence. The case-specificity principle requires that factfinders base their decisions on the relative plausibility of the stories describing the parties’ entitlement–accountability relationship. The cost-minimization principle demands that factfinders minimize the cost of errors and the cost of avoiding errors as a total sum. The equal-best principle mandates that factfinders afford every person the maximal feasible protection against risk of error while equalizing that protection across the board. …

Catalogs, Alex Stein, Gideon Parchomovsky

Alex Stein

It is a virtual axiom in the world of law that legal norms come in two prototypes: rules and standards. The accepted lore suggests that rules should be formulated to regulate recurrent and frequent behaviors, whose contours can be defined with sufficient precision. Standards, by contrast, should be employed to address complex, variegated, behaviors that require the weighing of multiple variables. Rules rely on an ex ante perspective and are therefore considered the domain of the legislator; standards embody a preference for ex post, ad-hoc, analysis and are therefore considered the domain of courts. The rules/standards dichotomy has become a …

Intellectual Property Defenses, Alex Stein, Gideon Parchomovsky

Alex Stein

This Article demonstrates that all intellectual property defenses fit into three conceptual categories: general, individualized, and class defenses. A general defense challenges the validity of the plaintiff’s intellectual property right. When raised successfully, it annuls the plaintiff’s right and relieves not only the defendant, but also the entire world of the duty to comply with it. An individualized defense is much narrower in scope: Its successful showing defeats the specific infringement claim asserted by the plaintiff, but leaves the plaintiff’s right intact. Class defenses form an in-between category: They create an immunity zone for a certain group of users to …

Are People Probabilistically Challenged? Book Review Of Daniel Kahneman, Thinking, Fast And Slow (2011), Alex Stein

Alex Stein

Daniel Kahneman’s recent book, Thinking, Fast and Slow, is a must-read for any scholar and policymaker interested in behavioral economics. Thus far, behavioral economists did predominantly experimental work that uncovered discrete manifestations of people’s bounded rationality: representativeness, availability, anchoring, overoptimism, base-rate neglect, hindsight bias, loss aversion, and other misevaluations of probability and utility. This work has developed no causal explanations for these misevaluations. Kahneman’s book takes the discipline to a different level by developing an integrated theory of bounded rationality’s causes and characteristics. This theory holds that humans use two distinct modes of reasoning, intuitive (System 1) and deliberative (System …

The Relational Contingency Of Rights, Alex Stein, Gideon Parchomovsky

Alex Stein

In this Article, we demonstrate, contrary to conventional wisdom, that all rights are relationally contingent. Our main thesis is that rights afford their holders meaningful protection only against challengers who face higher litigation costs than the rightholder. Contrariwise, challengers who can litigate more cheaply than a rightholder can force the rightholder to forfeit the right and thereby render the right ineffective. Consequently, in the real world, rights avail only against certain challengers but not others. This result is robust and pervasive. Furthermore, it obtains irrespectively of how rights and other legal entitlements are defined by the legislator or construed by …

Strategic Enforcement, Alex Stein, Margaret H. Lemos

Alex Stein

Doctrine and scholarship recognize two basic models of enforcing the law: the comprehensive model, under which law-enforcers try to apprehend and punish every violator within the bounds of feasibility; and the randomized model, under which law enforcers economize their efforts by apprehending a small number of violators and heightening their penalties so as to make violations unattractive. This Article supplements this list of options by developing a strategic model of law enforcement. Under this model, law enforcers concentrate their effort on the worst, or most rampant, violators at a given point in time while leaving all others unpunished. This enforcement …
