Georgia Code Title 9. Civil Practice § 9-11-60

(a) Collateral attack.A judgment void on its face may be attacked in any court by any person. In all other instances, judgments shall be subject to attack only by a direct proceeding brought for that purpose in one of the methods prescribed in this Code section.

(b) Methods of direct attack.A judgment may be attacked by motion for a new trial or motion to set aside. Judgments may be attacked by motion only in the court of rendition.

(c) Motion for new trial.A motion for new trial must be predicated upon some intrinsic defect which does not appear upon the face of the record or pleadings.

(d) Motion to set aside.A motion to set aside may be brought to set aside a judgment based upon:

(e) Complaint in equity.The use of a complaint in equity to set aside a judgment is prohibited.

(f) Procedure; time of relief.Reasonable notice shall be afforded the parties on all motions. Motions to set aside judgments may be served by any means by which an original complaint may be legally served if it cannot be legally served as any other motion. A judgment void because of lack of jurisdiction of the person or subject matter may be attacked at any time. Motions for new trial must be brought within the time prescribed by law. In all other instances, all motions to set aside judgments shall be brought within three years from entry of the judgment complained of.

(g) Clerical mistakes.Clerical mistakes in judgments, orders, or other parts of the record and errors therein arising from oversight or omission may be corrected by the court at any time of its own initiative or on the motion of any party and after such notice, if any, as the court orders.

(h) Law of the case rule.The law of the case rule is abolished; but generally judgments and orders shall not be set aside or modified without just cause and, in setting aside or otherwise modifying judgments and orders, the court shall consider whether rights have vested thereunder and whether or not innocent parties would be injured thereby; provided, however, that any ruling by the Supreme Court or the Court of Appeals in a case shall be binding in all subsequent proceedings in that case in the lower court and in the Supreme Court or the Court of Appeals as the case may be.
