Abrogation

The destruction or annulling of a former law by an act of the legislative power, by constitutional authority, or by usage. It stands opposed to rogation; and is distinguished from derogation, which implies the taking away of only some part of a law; from subrogation, which denotes the substitution of a clause; from dispensation, which only sets it aside in a particular instance; and from antiquation, which is the refusing to pass a law.

For example, the abrogation of the Eighteenth Amendment to the Constitution, which prohibited the manufacture or sale of intoxicating liquors, was accomplished by the enactment of the Twenty-first Amendment. Implied abrogation takes place when a new law contains provisions that are positively contrary to a former law, without expressly abrogating such laws, or when the order of things for which the law has been made no longer exists.
