New directions in theories of criminalization

Over the past few decades criminal law scholarship has been dominated by moralistic conceptions of the criminal law but recent years have seen the emergence of the so-called ‘political turn’ in criminal law theorizing. In this article I analyze the theory proffered by Vincent Chiao, one of the most persuasive proponents of the political or ‘public law’ trend, in contradistinction to the moralistic theory of criminalization defended by Anthony Duff. I demonstrate that the differences between the two theories are more nuanced and more complex than first appears. In fact, because of how it concerns itself only with moral wrongdoing of a certain kind – namely, public wrongdoing – it turns out that Duff’s theory is best analyzed as a version of the public law account of criminal law. I argue that taking on Chiao’s public law approach, but allowing it to be informed by the principles of Duff’s (rather than Chiao’s) political philosophy, holds out the most promise for reaching a satisfactory conception of criminal law. I finish by considering this conclusion in light of the fact that hybrid theories are nothing new in the debate between retributivism and instrumentalism, a dividing line along which Chiao’s and Duff’s theories fall. I argue that the particular hybrid theory I defend holds important advantages over other such theories.
