¶1 We reverse the judgment of the Court of Appeals in Grant v. State, 237 Ga. App. 892 (515 SE2d 872) (1999), because the State now concedes that the jury oath which is mandated by OCGA § 15-12-139 was never administered in this case. 1 It follows that Grant’s motion to set aside his conviction should have been granted and the case must be remanded for retrial. See Slaughter v. State, 100 Ga. 323 (28 SE 159) (1897).
¶2 Judgment reversed.
