 In contrast, the holder of a power-right does have an ability. This is the normative ability to exercise authority in a certain way. (Sumner 1987, 28) This normative ability confers freedom in a different sense. A judge is free to sentence a convicted criminal to prison. The judge is not merely allowed to sentence the prisoner: her power-right gives her the ability—that is, the authority—to do so. Her (power-) right makes her free to sentence in a way that non-judges are not free to sentence.
