The property of subjects is under the eminent domain of the state, so that the state or those who act for it may use and even alienate and destroy such property, not only in the case of extreme necessity, in which even private persons have a right over the property of others, but for ends of public utility, to which ends those who founded civil society must be supposed to have intended that private ends should give way. But, when this is done, the state is bound to make good the loss to those who lose their property.
