There is a difference between finding the most recent cases on a legal issue and making sure those cases are still good law.
You can use subscription databases (e.g., Westlaw Edge and Lexis+) and free websites (e.g., SC Judicial Department and Google Scholar) to find the most recent cases on a specific legal issue in your jurisdiction.
However, to make sure the cases you find are still good law for the legal issue you are researching, you must use a citator. Keycite® is the citator for Westlaw Edge and Shepard's® is the citator for Lexis+.
Shepard's® is also available for all state and federal cases through the University of South Carolina's subscription to Nexis Uni™.
You must update every case you plan to cite to confirm that it still supports the point of law for which you are citing it. An opinion may be reversed, overruled, or superseded by statute, i.e., it has negative history. The precedential value of an opinion may also be affected when subsequent courts distinguish it, decline to follow it, criticize it, or question its validity, i.e., it has negative treatment.
The Westlaw example below shows a red flag on the South Carolina Court of Appeals State v. Jenkins opinion that was reversed by the South Carolina Supreme Court.
In Lexis, the State v. Jenkins opinion appears with a red stop sign.
The videos below demonstrate how to do both.
