Yes, you have a right to see the evidence/discovery in your case before you are forced to enter a plea of guilty or not guilty. However, you or your attorney must first file a Motion for Discovery in this case. This Motion for Discovery is usually made pursuant to the SC Rules of Criminal Procedure, Rule 5, and well as the Supreme Court case Brady v. Maryland, and its progeny. This is why a Motion for Discovery is sometimes referred to as a Rule 5/Brady motion.
