In this area of law, the Rules of Evidence is the most important primary source. In Georgia, they are codified in Title 24 of the Official Code of Georgia Annotated. In 2011, the rules were revised to closely match their federal counterparts (in numbering and substance), considerably increasing the influence of the latter. Although most of the important codified law is contained here, you should still thoroughly research the rest of the O.C.G.A. to ensure that you find all of the relevant law.
