    The reason model of precedential constraint is supposed to generate a stricter doctrine than the minimalist result model. In the standard setting in which these models were originally formalized, that is exactly what we find. Surprisingly, however, in the more complex dimensional setting, the models become indistinguishable. In this paper, we provide an illuminating explanation of the collapse. We also shed light on recent proposals to modify the reason model, or the underlying dimensional setti…Read more

    Refining the argument from democracy
    Journal of Ethics and Social Philosophy 29 (3): 452-501. 2025.
    This paper presents a new version of the democratic argument for the freedom of expression that has the resources to give a plausible reply to the perennial objection—ordinarily considered fatal—that such accounts fail to deliver protections for abstract art, instrumental music, and lots of other deserving nonpolitical speech. The argument begins with the observation that there are different things that a free speech theory might aim to accomplish. It will hope to justify a right to free speech,…Read more

    The naturalized epistemology approach to evidence
    In Christian Dahlman, Alex Stein & Giovanni Tuzet (eds.), Philosophical Foundations of Evidence Law, Oxford University Press. 2021.
    Studying evidence law as part of naturalized epistemology means using the tools and results of the sciences to evaluate evidence rules based on the accuracy of the verdicts they are likely to produce. In this chapter, we introduce the approach and address skeptical concerns about the value of systematic empirical research for evidence scholarship, focusing, in particular, on worries about the external validity of jury simulation studies. Finally, turning to applications, we consider possible ref…Read more

    Carnapian frameworks
    Synthese 199 (1-2): 4097-4126. 2021.
    Carnap’s seminal ‘Empiricism, Semantics and Ontology’ makes important use of the notion of a framework and the related distinction between internal and external questions. But what exactly is a framework? And what role does the internal/external distinction play in Carnap’s metaontology? In an influential series of papers, Matti Eklund has recently defended a bracingly straightforward interpretation: A Carnapian framework, Eklund says, is just a natural language. To ask an internal question, the…Read more

    Vertical precedents in formal models of precedential constraint
    Artificial Intelligence and Law 27 (3): 253-307. 2019.
    The standard model of precedential constraint holds that a court is equally free to modify a precedent of its own and a precedent of a superior court—overruling aside, it does not differentiate horizontal and vertical precedents. This paper shows that no model can capture the U.S. doctrine of precedent without making that distinction. A precise model is then developed that does just that. This requires situating precedent cases in a formal representation of a hierarchical legal structure, and ad…Read more
