The advantage of codification is that once the state legislature becomes accustomed to writing new laws as amendments to an existing code, the code will usually reflect democratic sentiment as to what the current law is (though the entire state of the law must always be ascertained by reviewing case law to determine how judges have interpreted a particular codified statute).
法典化的优势在于，一旦州立法机关习惯于将新法的制定作为现有法典的修正案，法典就会经常反映出对现有法律的民意(虽然整个法规体系必须由复查判例法确定法官怎样解释法典中某项特定的法律才能得知)。
