Derogation, in civil law and common law, is the partial suppression of a law. In contrast, annulment is the total abolition of a law by explicit repeal, and obrogation is the partial or total modification or repeal of a law by the imposition of a later and contrary one. It is sometimes used, loosely, to mean abrogation, as in the legal maxim lex posterior derogat priori ("a subsequent law derogates the previous one").
