ABROGATION
ABROGATION — (from Latin abrogatio) the formal repeal or abolition of a law, right, or agreement, typically because it is obsolete or contrary to current public policy. Abrogation is usually achieved by enacting a new law. Related concepts include: strict abrogation (complete replacement of an old law), derogation (partial repeal), obrogation (modification of an existing law), and subrogation (supplementing an old law).
