Benjamin Ewing and Douglas Kysar’s article, Prods and Pleas, discusses one benefit of the fragmented American governance system: the opportunity for institutions to influence the agendas of other, more powerful institutions. The authors illustrate this point with an extensive discussion of the potential for common law nuisance cases to direct congressional attention to the issue of climate change. Their general point is well taken, but they focus too heavily on the common law rather than the more important judicial role in public law, and they mention only in passing the role of states as independent policy centers. Furthermore, besides nudging Congress or the executive branch, public law litigation and state legislative activity can also help fill the gaps created by congressional or presidential policy defaults.

This Essay comments on Benjamin Ewing and Douglas A. Kysar’s article, Prods and Pleas: Limited Government in an Era of Unlimited Harm. Ewing and Kysar suggest that we augment the traditional conception of constitutional “checks and balances” with one of “prods and pleas,” i.e., that different branches of government can provide incentives to induce action from other branches. They use federal climate nuisance litigation as an example of how such prods and pleas can and should operate. In the existing political climate, I am skeptical that governmental branches listen to reasoned arguments from other branches; thus, I argue that “pleas” will be ineffective. Ewing and Kysar’s theory of prods, however, contains an important insight. Branches often respond to political incentives, such that when one branch reaches a decision that undermines the political goals of key actors in other branches (a “prod”), action is possible. In this Age of Dysfunction, when one of the major American political parties seeks to paralyze legislative action, I suggest three areas where judicial prodding might be appropriate: 1) where legislation is blocked by a filibuster; 2) where opposition to legislation rejects science; and 3) where the legislative process produces results that discriminate against diffuse and invisible (and thus powerless) groups. I then use Ewing and Kysar’s example of climate change policy and argue that under current circumstances, judicial prodding is, in fact, appropriate.

This Essay argues that we have been undergoing a profound sociocultural transformation over the last several centuries, which relates to the emergence of international law. This transformation is every bit as fundamental as those we once went through when transitioning from hunter-gatherer forms of life (which did not yet have legal systems or engage a distinctive sense of legal obligation) to more sedentary forms of agricultural life (with larger population densities, incipient domestic legal institutions, and—ultimately—an emergent distinction between morality and law). The primary mechanism that has been supporting this transformation is “outcasting”—as Oona Hathaway and Scott Shapiro have recently defined the term in their Yale Law Journal article of the same name. This Essay argues that outcasting provides the evolutionary stability conditions for a distinctive and emergent sense of international legal obligation in us. This shared sense of obligation is one of the basic preconditions for a genuine de facto system of international law—a fact that has important normative implications for how to evaluate international law.

In view of the billions of dollars and enormous effort that might otherwise be wasted, the public interest will be best served if the Supreme Court of the United States reaches the merits of the present challenges to the Patient Protection and Affordable Care Act (ACA) during its October 2011 Term. Potentially standing in the way, however, is the federal Tax Anti-Injunction Act (TAIA), which bars any “suit for the purpose of restraining the assessment or collection of any tax.” The dispute to date has mostly turned on the fraught and complex question of whether the ACA’s exaction for being uninsured qualifies as a “tax” for purposes of the TAIA. We argue that the Supreme Court need not resolve this issue because the TAIA does not apply for a distinct reason: the present challenges to the ACA do not have “the purpose” of restraining tax assessment or collection. In order for the TAIA not to bar refund suits, the TAIA must be read to bar suits with the immediate purpose of restraining tax assessment or collection. The present challenges do not have such an immediate purpose because the very authority to assess or collect will not exist until long after the litigation is concluded. Among other virtues, this resolution of the TAIA question does not predetermine whether the tax power justifies the minimum coverage provision.
