    Are there any rules?
    The Journal of Ethics 5 (3): 199-219. 2001.
    Widespread, deep controversy as to the content of the law of a community is compatible with the view that the law is a system of rules. I defend that view through a critique of Ronald Dworkin's discussion of Riggs v. Palmer 22 N.E. 188. Dworkin raised an important challenge for jurisprudence: to account for the fact that legal rights and duties are frequently controversial. I offer an explanation of the possibility of deep disagreement about the application of social rules, which reconciles cont…Read more

    The impossibility of the rule of law
    Oxford Journal of Legal Studies 19 (1): 1-18. 1999.
    No community fully achieves the ideal of the rule of law. Puzzles about the content of the ideal seem to make it necessarily unattainable (and, therefore, an incoherent ideal). Legal systems necessarily contain vague laws. They typically allow for change in the law, they typically provide for unreviewable official decisions, and they never regulate every aspect of the life of a community. It may seem that the ideal can never be achieved because of these features of legal practice. But I ask what…Read more

    Law is Necessarily Vague
    Legal Theory 7 (1): 377--83. 2001.
    In fact, law is necessarily very vague. So if vagueness is a problem for legal theory, it is a serious problem. The problem has to do with the ideal of the rule of law and with the very idea of law: if vague standards provide no guidance in some cases, how can the life of a community be ruled by law? The problem has long concerned philosophers of law; the papers at this symposium address it afresh by asking what legal theory may have to learn from (or contribute to) work on vagueness in philosop…Read more

    Vagueness and Legal Theory
    Legal Theory 3 (1): 37-63. 1997.
    The use of vague language in law has important implications for legal theory. Legal philosophers have occasionally grappled with those implications, but they have not come to grips with the characteristic phenomenon of vagueness: the sorites paradox. I discuss the paradox, and claim that it poses problems for some legal theorists (David Lyons, Hans Kelsen, and, especially, Ronald Dworkin). I propose that a good account of vagueness will have three consequences for legal theory: (i) Theories that…Read more

    Raz on Gaps: The Surprising Part
    In Lukas H. Meyer, Stanley L. Paulson & Thomas Winfried Menko Pogge (eds.), Rights, culture, and the law: themes from the legal and political philosophy of Joseph Raz, Oxford University Press. 2003.
    In English law, there are various ways in which contracts can be invalid or unenforceable because they are immoral — and yet English lawyers know that many contracts are conclusively binding. The first two sources of legal gaps that Joseph Raz identifies do not seem surprising. Vagueness in the sources of law leads to gaps in borderline cases, and there is a gap if the law includes inconsistent rules, with no way of deciding which is effective. In those situations it seems right to say that the …Read more

    How to Speak the Truth
    American Journal of Jurisprudence 46 (1): 229-248. 2001.
    Argues that some important problems in the theory of legal interpretation can be resolved with three techniques that John Finnis used in Natural Law and Natural Rights to address a methodological problem in jurisprudence: (1) The analogy principle: The application of a word such as “friendship” or “law” is not based on a set of features shared by each instance, but is based on similarities of a variety of kinds, seen by the people who use the words as justifying the extension of the word. (2) Th…Read more

    The Logic of Freedom and Power
    In Samantha Besson & John Tasioulas (eds.), The philosophy of international law, Oxford University Press. pp. 245-259. 2010.
    A state is sovereign if it has complete power within a political community, and complete independence. It may seem that the idea of sovereignty is objectionable because of two moral principles, or incoherent because of a paradox. The paradox is that a sovereign state must be capable of binding itself and must also be incapable of binding itself. The moral principles are that no state can justly exercise complete power internally, or complete independence (since complete independence would imply …Read more

    Morality and the Making of Law: Four Questions
    Jurisprudence 1 (2): 267-275. 2010.
    I address four questions that arise out of Nigel Simmonds's book, Law as a Moral Idea : Is politics a moral idea too? Is there any such thing as law making? Is there a right answer to every legal dispute? What justifies a judicial decision? To each question I propose an answer that shares much with Simmonds's views, but diverges. Simmonds is right to call law a 'moral idea', and that implies a connection between law and a moral ideal; in my view, the connection is compatible with a necessary con…Read more

    Vagueness in Law
    Oxford University Press. 2000.
    Vagueness leads to indeterminacies in the application of the law in many cases. This book responds to the challenges that those indeterminacies pose to a theory of law and adjudication. The book puts controversies in legal theory in a new light, using arguments in the philosophy of language to offer an explanation of the unclarities that arise in borderline cases for the application of vague expressions. But the author also argues that vagueness is a feature of law, and not merely of legal lang…Read more

    The infant in the snow
    In Timothy Endicott, Joshua Getzler & Edwin Peel (eds.), Properties of Law: Essays in Honour of Jim Harris, Oxford University Press. 2006.
    Suppose that you are wandering across the tundra, and you find an infant, all alone, in the snow. She is incapable of discourse, and yet she has the same human rights as anyone who is capable of discourse. Those rights do not depend on the practices or conventions of your people, or hers. Human discourse and human conventions play no role in human rights. I elaborate these claims through a critique of J.W. Harris’s groundbreaking analytical account of human rights. I conclude that some welfare r…Read more

    Interpretation, jurisdiction, and the authority of law
    American Philosophical Association Newsletter 6 14-19. 2007.
    People can be autonomous, if they are subject to authority. In particular, they can be autonomous if they are subject to the authority of law. I defend the first claim through a study of Joseph Raz's compelling account of authority; I claim that his work leads to the conclusion that autonomous judgment is needed to determine the jurisdiction of an authority, and to interpret its directives. I defend the second claim by arguing that law does not claim unlimited jurisdiction, and need not claim un…Read more
