    Innocence Lost: A Problem for Punishment as Duty
    Law and Philosophy 36 (3): 225-254. 2017.
    Constrained instrumentalist theories of punishment – those that seek to justify punishment by its good effects, but limit its scope – are an attractive alternative to pure retributivism or utilitarianism. One way in which we may be able to limit the scope of instrumental punishment is by justifying punishment through the concept of duty. This strategy is most clearly pursued in Victor Tadros’ influential ‘Duty View’ of punishment. In this paper, I show that the Duty View as it stands cannot find…Read more

    Prevention and the Limits of the Criminal Law (edited book)
    with Andrew Ashworth and Lucia Zedner
    Oxford University Press. 2013.
    Are preventive justice measures justified? Do they needlessly blur the boundaries between criminal and civil law, signalling a change in the architecture of security? The contributors in this volume re-assess the foundations for the range of coercive measures that states now take in the name of prevention and public protection.

    Should Retributivists Prefer Prepunishment?
    Social Theory and Practice 41 (2): 275-285. 2015.
    Some philosophers believe that we can, in theory, justifiably prepunish people—that is, punish them for a crime before they have committed that crime. In particular, it has been claimed that retributivists ought to accept prepunishment. The question of whether prepunishment can be justified has sparked an interesting and growing philosophical debate. In this paper I look at a slightly different question: whether retributivists who accept that prepunishment can be justified should prefer postpuni…Read more

    Could the Presumption of Innocence Protect the Guilty?
    Criminal Law and Philosophy 8 (2): 431-447. 2014.
    At criminal trial, we demand that those accused of criminal wrongdoing be presumed innocent until proven guilty beyond any reasonable doubt. What are the moral and/or political grounds of this demand? One popular and natural answer to this question focuses on the moral badness or wrongness of convicting and punishing innocent persons, which I call the direct moral grounding. In this essay, I suggest that this direct moral grounding, if accepted, may well have important ramifications for other ar…Read more

    Can I be a Luck Egaliatarian and a Rawlsian?
    Ethical Perspectives 19 (3): 371-397. 2012.
    Rawls’s difference principle and the position dubbed ‘luck egalitarianism’ are often viewed as competing theories of distributive justice. However, recent work has emphasised that Rawlsians and luck egalitarians are working with different understandings of the concept of justice, and thus not only propose different theories, but different theories of different things. Once they are no longer seen in direct competition, there are some questions to be asked about whether these two theories can be …Read more
