Georgia courts have expressly held "that upon an express stipulation of the parties that they shall be admissible, the results of a lie detector test shall be admissible as evidence for the jury to attach to them whatever probative value they may find them to have." Jones v. State, 309 Ga. App. 886 (2011); Harris v. State, 308 Ga. App. 523 (2011). Without a prior stipulation, the results of a polygraph are not admissible.
