The annulment of a law by constitutional authority. It stands opposed to rogation; and 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 dispensation, which only sets it aside in a particular instance; and from on-liquation, which is the refusing to pass a law. Encyc. Lond.
—Implied abrogation. A statute is said to work an "implied abrogation" of an earlier one, when the later statute contains provisions which are inconsistent with the further continuance of the earlier law; or a statute is impliedly abrogated when the reason of it or the object for which it was passed, no longer exists.
