What is the criminal law for? One influential answer is that the criminal law vindicates pre-political rights and condemns wrongdoing. In Criminal Law in the Age of the Administrative State, Vincent Chiao offers an alternative, public law account. By starting with the political morality of public institutions, rather than the interpersonal morality of private relationships, the public law account makes the case for regarding criminal law and criminal justiceas animated by the same political virtues that gave rise to the institutions of the modern administrative and welfare state. Chiao then shows how this approach to criminal justice provides a fresh perspective on a range of problems, from mass incarceration to overcriminalization, to due process and thecollateral consequences of a criminal conviction.
