Abstract

Thomas Hurka derives rights to punish from what I will term the Libertarian Rights Principle, which is “that there is really only one natural right, namely the equal right of all persons to the most extensive liberty compatible with a like liberty for other persons, and that all other natural rights are species or instances of the right to liberty.” These rights to punish, he says, extend only to punishing violators of rights, never to “punishing” the innocent; extend only to punishing for violations pursuant to intentions publicly announced prior to these violations; are subject to the “upper limit qualification” that a permissible punishment for the violation of a right cannot be an act that would violate a more important right ; and are subject to the “minimum necessary qualification” that a punishment p for violating a right r is not permissible if a punishment p' that would, were it permitted, violate a less important right than would p, would protect r as effectively as would p.
