Winner of the 2021 Scribes Book Award From two legal luminaries, a highly original framework for restoring confidence in a government bureaucracy increasingly derided as “the deep state.” Is the modern administrative state illegitimate? Unconstitutional? Unaccountable? Dangerous? Intolerable? American public law has long been riven by a persistent, serious conflict, a kind of low-grade cold war, over these questions. Cass Sunstein and Adrian Vermeule argue that the administrative state can be redeemed, as long as public officials are constrained by what they call the morality of administrative law. Law and Leviathan elaborates a number of principles that underlie this moral regime. Officials who respect that morality never fail to make rules in the first place. They ensure transparency, so that people are made aware of the rules with which they must comply. They never abuse retroactivity, so that people can rely on current rules, which are not under constant threat of change. They make rules that are understandable and avoid issuing rules that contradict each other. These principles may seem simple, but they have a great deal of power. Already, without explicit enunciation, they limit the activities of administrative agencies every day. But we can aspire for better. In more robust form, these principles could address many of the concerns that have critics of the administrative state mourning what they see as the demise of the rule of law. The bureaucratic Leviathan may be an inescapable reality of complex modern democracies, but Sunstein and Vermeule show how we can at last make peace between those who accept its necessity and those who yearn for its downfall.

Winner of the Scribes Book Award "As brilliantly imaginative as it is urgently timely." -Richard H. Fallon, Jr., Harvard Law School "At no time more than the present, a defense of expertise-based governance and administration is sorely needed, and this book provides it with gusto." -Frederick Schauer, author of The Proof A highly original framework for restoring confidence in a government bureaucracy increasingly derided as "the deep state." Is the modern administrative state illegitimate? Unconstitutional? Unaccountable? Dangerous? America has long been divided over these questions, but the debate has recently taken on more urgency and spilled into the streets. Cass Sunstein and Adrian Vermeule argue that the administrative state can be redeemed so long as public officials are constrained by morality and guided by stable rules. Officials should make clear rules, ensure transparency, and never abuse retroactivity, so that current guidelines are not under constant threat of change. They should make rules that are understandable and avoid issuing contradictory ones. These principles may seem simple, but they have a great deal of power. Already, they limit the activities of administrative agencies every day. In more robust form, they could address some of the concerns of critics who decry the "deep state" and yearn for its downfall. "Has something to offer both critics and supporters...a valuable contribution to the ongoing debate over the constitutionality of the modern state." -Review of Politics "The authors freely admit that the administrative state is not perfect. But, they contend, it is far better than its critics allow." -Wall Street Journal

How should judges, in America and elsewhere, interpret statutes and the Constitution? Previous work on these fundamental questions has typically started from abstract views about the nature of democracy or constitutionalism, or the nature of legal language, or the essence of the rule of law. From these conceptual premises, theorists typically deduce an ambitious role for judges, particularly in striking down statutes on constitutional grounds. In this book, Adrian Vermeule breaks new ground by rejecting both the conceptual approach and the judge-centered conclusions of older theorists. Vermeule shows that any approach to legal interpretation rests on institutional and empirical premises about the capacities of judges and the systemic effects of their rulings. Drawing upon a range of social science tools from political science, economics, decision theory, and other disciplines, he argues that legal interpretation is above all an exercise in decisionmaking under severe empirical uncertainty. In view of their limited information and competence, judges should adopt a restrictive, unambitious set of tools for interpreting statutory and constitutional provisions, deferring to administrative agencies where statutes are unclear and deferring to legislatures where constitutional language is unclear or states general aspirations.

The Constitution of Risk is the first book to combine constitutional theory with the theory of risk regulation. The book argues that constitutional rulemaking is best understood as a means of managing political risks. Constitutional law structures and regulates the risks that arise in and from political life, such as an executive coup or military putsch, political abuse of ideological or ethnic minorities, or corrupt self-dealing by officials. The book claims that the best way to manage political risks is an approach it calls optimizing constitutionalism in contrast to the worst-case thinking that underpins precautionary constitutionalism, a mainstay of liberal constitutional theory. Drawing on a broad range of disciplines such as decision theory, game theory, welfare economics, political science, and psychology, this book advocates constitutional rulemaking undertaken in a spirit of welfare maximization, and offers a corrective to the pervasive and frequently irrational attitude of distrust of official power that is so prominent in American constitutional history and discourse."

Human reason is limited. What are the consequences of this fact for the contested lawmaking claims between courts, legislatures and the executive branch? In light of the limits of reason, how should legal institutions be designed? In Law and the Limits of Reason, Adrian Vermeule criticizes the view that the limits of reason counsel in favor of judicial lawmaking in the style of the common law. He argues that there is no logical connection between the limits of reason, on the one hand, and the superiority of common law or of judge-made constitutional law on the other. The relatively small number of judges on relevant courts, their limited informational base and generalist rather than specialized skills, ensure that judicial reason is itself sharply limited and that the argument to judicial lawmaking from the limits of reason outruns the logical, causal, and evidentiary support.
Instead, Adrian Vermeule proposes and defends a "codified constitution" - a regime in which legislatures have the primary authority to develop constitutional law over time, through statutes and constitutional amendments. Precisely because of the limits of human reason, large modern legislatures, with their numerous membership, complex internal structures for processing information and their abundant informational resources, are the most effective lawmaking institutions. Law and the Limits of Reason, now in paperback, serves as a thought-provoking companion to any constitutional law course of study.

Ronald Dworkin once imagined law as an empire and judges as its princes. But over time, the arc of law has bent steadily toward deference to the administrative state. Adrian Vermeule argues that law has freely abandoned its imperial pretensions, and has done so for internal legal reasons. In area after area, judges and lawyers, working out the logical implications of legal principles, have come to believe that administrators should be granted broad leeway to set policy, determine facts, interpret ambiguous statutes, and even define the boundaries of their own jurisdiction. Agencies have greater democratic legitimacy and technical competence to confront many issues than lawyers and judges do. And as the questions confronting the state involving climate change, terrorism, and biotechnology (to name a few) have become ever more complex, legal logic increasingly indicates that abnegation is the wisest course of action. As Law's Abnegation makes clear, the state did not shove law out of the way. The judiciary voluntarily relegated itself to the margins of power. The last and greatest triumph of legalism was to depose itself.

A constitutional order is a system of systems. It is an aggregate of interacting institutions, which are themselves aggregates of interacting individuals. In The System of the Constitution, Adrian Vermeule analyzes constitutionalism through the lens of systems theory, originally developed in biology, computer science, political science and other disciplines. Systems theory illuminates both the structural constitution and constitutional judging, and reveals that standard views and claims about constitutional theory commit fallacies of aggregation and are thus invalid. By contrast, Vermeule explains and illustrates an approach to constitutionalism that considers the systemic interactions of legal and political institutions and of the individuals who act within them.

In Terror in the Balance, Posner and Vermeule take on civil libertarians of both the left and the right, arguing that the government should be given wide latitude to adjust policy and liberties in the times of emergency. They emphasize the virtues of unilateral executive actions and argue for making extensive powers available to the executive as warranted. The judiciary should neither second-guess security policy nor interfere on constitutional grounds. In order to protect citizens, government can and should use any legal instrument that is warranted under ordinary cost-benefit analysis. The value gained from the increase in security will exceed the losses from the decrease in liberty. At a time when the 'struggle against violent extremism' dominates the United States' agenda, this important and controversial work will spark discussion in the classroom and intellectual press alike.

Ever since Arthur M. Schlesinger Jr. used "imperial presidency" as a book title, the term has become central to the debate about the balance of power in the U.S. government. Since the presidency of George W. Bush, when advocates of executive power such as Dick Cheney gained ascendancy, the argument has blazed hotter than ever. Many argue the Constitution itself is in grave danger. What is to be done? The answer, according to legal scholars Eric Posner and Adrian Vermeule, is nothing. In The Executive Unbound, they provide a bracing challenge to conventional wisdom, arguing that a strong presidency is inevitable in the modern world. Most scholars, they note, object to today's level of executive power because it varies so dramatically from the vision of the framers of the Constitution. But Posner and Vermeule find fault with James Madison's premises. Like an ideal market, they write, Madison's separation of powers has no central director, but it lacks the price system which gives an economy its structure; there is nothing in checks and balances that intrinsically generates order or promotes positive arrangements. In fact, the greater complexity of the modern world produces a concentration of power, particularly in the White House. The authors chart the rise of executive authority, noting that among strong presidents only Nixon has come in for severe criticism, leading to legislation which was designed to limit the presidency, yet which failed to do so. Political, cultural and social restraints, they argue, have been more effective in preventing dictatorship than any law. The executive-centered state tends to generate political checks that substitute for the legal checks of the Madisonian constitution. Piety toward the founders and a historic fear of tyranny have been powerful forces in American political thinking. Posner and Vermeule confront them both in this startlingly original contribution.
