In the Principles of the Penal Code, Jeremy Bentham described offences that he labelled presumed or evidentiary. The conduct penalized under such offences is punished not because it is intrinsically wrong, but because it probabilistically indicates the presence of an intrinsic wrong. Bentham was sceptical of the need to create offences, but grudgingly accepted their value in light of deficiencies in procedure and the judiciary. These days the scepticism is even greater, with courts and commentators in the United States, Canada, (...) the United Kingdom and elsewhere believing that such offences deny a defendant the right to establish that he did not engage in the conduct that the presumed offence probabilistically but not necessarily indicates. On closer analysis, however, such scepticism appears unjustified. Almost all offences, and indeed almost all legal rules, are premised on a probabilistic relationship between the behaviour the rule encompasses and the behaviour that is the rule-maker's real concern. Presumed offences may make this relationship especially obvious, but it is a relationship that exists whenever the law operates by the use of rules. (shrink)

When does a defendant not deserve punishment because he is unaware that his conduct breaches a penal statute? Retributivists must radically rethink their answer to this question to do justice to our moral intuitions. I suggest that modest progress on this topic can be made by modeling our approach to ignorance of law on our familiar approach to ignorance of fact. We need to distinguish different levels of culpability in given mistakes and to differentiate what such mistakes may be about. (...) I discuss the advantages and disadvantages of this approach with special attention to how to contrast offenses from defenses. The alternative I tend to favor probably should not be implemented in existing penal codes. As a result, we are likely to remain dissatisfied with the decisions made by our criminal justice system about the exculpatory effect of ignorance of law. (shrink)

Orthodox criminal law doctrine treats mistakes of law and mistakes of fact differently for purposes of both exculpation and inculpation. Kenneth Simons’ paper in general defends this orthodoxy. I have earlier criticized the criminal law’s attempt to distinguish mistakes of law from mistakes of fact, and I continue to maintain, in opposition to Simons, that the distinction is problematic.

Gideon Yaffe is to be commended for beginning his exhaustive treatment by asking a surprisingly difficult question: Why punish attempts at all? He addresses this inquiry in the context of defending (what he calls) the transfer principle: “If a particular form of conduct is legitimately criminalized, then the attempt to engage in that form of conduct is also legitimately criminalized.” I begin by expressing a few reservations about the transfer principle itself. But my main point is that we are justified (...) in punishing attempts only when and for a different reason than Yaffe provides. I argue that attempts are legitimately punished only when they raise the risk that a harm will actually occur. To overcome the problems my explanation encounters with factually impossible attempts, I suggest an account of risk that relies on ordinary language and possible worlds. (shrink)

In Ignorance of Law, Douglas Husak’s main thesis is that ignorance of the law typically provides an excuse for breaking the law, but in the case of recklessness he claims that the excuse it provides is only a partial one, and in the case of willful ignorance he claims that it provides no excuse at all. In this paper I argue that, given the general principle to which Husak appeals in order to support his main thesis, he should revise his (...) position on the exculpatory significance of both recklessness and willful ignorance.

Proposing and consenting to sex are things that ordinary people manage to do all the time, yet legal regulation of sex seems to be an intractable problem. No one is satisfied with rape law, but no one knows quite what to do about it.
