An appellate court decision can be reversed or overruled; therefore, you must always update every case you find to confirm that it is still good law.
Citators track a case to update it and to provide cases and secondary sources that cite it. KeyCite® is the citator for Westlaw. Shepard's® is the citator for LexisNexis.
South Carolina colleges, universities and public libraries may subscribe to Westlaw or Lexis, which will include electronic access to KeyCite® or Shepard's®, respectively, for their patrons.
The law school library maintains a current print set of Shepard's South Carolina Citations for updating South Carolina appellate court opinions.
Shepard's® is also available for all state and federal cases through the University of South Carolina's subscription to LexisNexis Academic.
