Derogation
(重定向自Derogate)
Derogation is the partial suppression of a law, as opposed to abrogation—total abolition of a law by explicit repeal—and obrogation—the partial or total modification or repeal of a law by the imposition of a later and contrary one. The term is used in canon law, civil law, and common law. It is sometimes used, loosely, to mean abrogation, as in the legal maxim: Lex posterior derogat priori, i.e. a subsequent law imparts the abolition of a previous one.
