A Coe is a type of legislation that purports to exhaustively cover a complete system of law or a particular area of law as it existed at the time the code was enacted, by a process of codification. Though the process and motivations for codification are similar in common law and civil law systems, their usage is different. In a civil law country, a Code typically exhaustively covers the complete system of law. By contrast, in a common law country a Code is a less common form of legislation, which differs from usual legislation that, when enacted, modify the existing common law only to the extent of its express or implicit provision, but otherwise leaves the common law intact. By contrast, a code entirely replaces the common law in a particular area, leaving the common law inoperative unless and until the code is repealed.[disputed]
