When you Shepardize® a case [called KeyCite in WestlawNext], LexisNexis provides a report showing every opinion where that case has been referenced, all treatments of the case, and, most importantly, whether or not the case is "good law." If the case has been overruled, it is considered "bad law" and may no longer be cited as a legal precedent.
