    Justifications, Powers, and Authority
    Yale Law Journal 117 1070. 2008.
    Criminal law theory made a significant advance roughly thirty years ago when George Fletcher popularized the important conceptual distinction between justifications and excuses. In the intervening years, however, very little progress has been made in exploring the structure and function of justification defenses. The reason for this failure, I suggest, is a widely shared misconception about their place within the criminal law’s institutional structure. Contrary to what is generally believed, it …Read more

    Policing and Public Office
    University of Toronto Law Journal 70 248-266. 2020.
    In this paper, I argue that policing can be defended as consistent with the equality of all before the law – but not by denying that policing occupies a special place in our legal order that is dangerously close to certain ancien régime privileges. In order to defend the special privileges of policing, it is essential to show that they are something quite different from the ancien régime privileges that they in some respects resemble. The crucial conceptual tool for making that argument is the i…Read more

    Reinventing the Nightwatchman State?
    University of Toronto Law Journal 60 425-443. 2010.
    This article raises a principled objection to the privatization of certain core police services. Whereas most of the literature critical of privatizing security services has focused on the negative consequences of doing so (corruption, waste, etc.), the argument here focuses squarely on the standing of private parties to perform police services. According to an important strain of liberal political theory, certain tasks are assigned to the state not because it is deemed to be more efficient at d…Read more

    The Constitution of Criminal Law: Justifications, Policing and the State’s Fiduciary Duties (review)
    Criminal Law and Philosophy 5 (3): 259-276. 2011.
    This paper, originally written for a conference on criminal law in times of emergency, considers the implications of the ‘German Airliner case’ for criminal law theory. In that case, the German constitutional court struck down as unconstitutional a law empowering state officials to order the shooting down of a hijacked plane on the grounds that the state could not order the killing of innocent civilians. Some have argued that despite this ruling, individual officials should still be entitled to …Read more

    Criminal Punishment and the Right to Rule
    University of Toronto Law Journal 70 44-63. 2019.
    Criminal justice is much more deeply connected to the very possibility of state authority than is usually understood. In this article, I argue that, whatever else criminal justice might accomplish, there is one task that it must accomplish. This, I argue, is because a certain idea of criminal justice is built into the very idea of state authority as we know it. It is just part of the idea of individuals having a private right, I argue, that there exists a legal mechanism for vindicating those ri…Read more

    How can we make moral sense of the international humanitarian law doctrine of combatant immunity? The doctrine is morally shocking to many: It holds soldiers on both sides of a war immune from criminal prosecution for their otherwise criminal acts of killing, maiming, destroying property, etc., carried out as part of their country's war effort. That is, soldiers who kill as part of an attack benefit from the immunity just as much as those defending their country. Traditionally, just war theorist…Read more

    Philosophical Foundations of Constitutional Law (edited book)
    Oxford University Press UK. 2016.
    Constitutional law has been and remains an area of intense philosophical interest, and yet the debate has taken place in a variety of different fields with very little to connect them. In a collection of essays bringing together scholars from several constitutional systems and disciplines, Philosophical Foundations of Constitutional Law unites the debate in a study of the philosophical issues at the very foundations of the idea of a constitution: why one might be necessary; what problems it must…Read more
