Abstract
The chapter concerns the relationship between the justification of criminal law and punishment and the justification of the state. It briefly surveys the debate between retributivists and consequentialists and argues that both are inappropriate when it comes to state punishment. It next turns to arguments by Vincent Chiao, Malcolm Thorburn, and Antony Duff that locate criminal law and punishment in public law. The final parts of the chapter develop an account of criminal law and punishment as best understood as constitutive elements of a liberal political community necessary to ensure stability, to reinforce the commitment of the members to the rules as regulative of their plans of life, and to communicate and censure the offender for the wrong that has been done.
