Abstract
It is common practice in the United Kingdom, the United States, and other common law countries to reduce criminal sentences in response to guilty pleas. This chapter contends that this practice violates the commonly accepted prohibiton on punishment of the innocent. I first consider various interpretations of what this prohibition requires of a system of punishment. Then I contend that insofar as sentence reductions provide significant prudential incentives to innocent people to plead guilty, these reductions run afoul of the most plausible construal of the prohibition on punishment of the innocent. I consider and respond to some possible objections, and then I consider the implications of my account.
