Citators developed as a way to check that a case was still good law. They are useful in a variety of contexts – updating statutes, finding additional sources, etc., but they are really important in determining whether you can rely on a case. Because cases are published chronologically and geographically, they are not ever organized by subject or updated the way statutes are. Without a citator, there’s no way to tell if a case has been overturned or otherwise criticized or questioned
