Abrogation

Abrogation [abrogatio, Lat.], the act of annulling; the repeal of a law. It stands opposed to rogation: it is distinguished from derogation, which implies the taking away only some part of a law; from subrogation, which denotes the adding a clause to it; from obrogation, which implies the limiting or restraining it; from dispensation, which only sets it aside in a particular instance; and from antiquation, which is the refusing to pass a law, Encyc.
