John Hadden is the author of Georgia Law of Evidence, published by Thomson Reuters, which is updated annually each fall with the latest important Georgia decisions and evidence rule changes. These rules govern evidentiary issues in Georgia trial courts in civil and criminal matters and are largely patterned on the Federal Rules of Evidence since an update in 2013.

John also offers a free Georgia Evidence Code Quick Reference Guide summarizing the evidence code, which is provided for judges and lawyers across the state.
