Obrogation
In civil law, obrogation (Latin: obrogat from obrogare) is the modification or repeal of a law in whole or in part by issuing a new law.
In the canon law of the Catholic Church, obrogation is the enacting of a contrary law that is a revocation of a previous law; it may also be the partial cancellation or amendment of a law, decree, or legal regulation by the imposition of a newer one.
