Id quod nostrum est
Id quod nostrum est, sine facto nostro ad alium transferi non potest. What belongs to us cannot be transferred to another without our consent. Dig. 50, 17, 11. But this must be understood with this qualification, that the government may take property for public use, paying the owner its value. The title to property may also be acquired, with the consent of the owner, by a judgment of a competent tribunal.
