Georgia Code Title 51. Torts § 51-7-82

(a) It shall be a complete defense to any claim for abusive litigation that the person against whom a claim of abusive litigation is asserted has voluntarily withdrawn, abandoned, discontinued, or dismissed the civil proceeding, claim, defense, motion, appeal, civil process, or other position which the injured person claims constitutes abusive litigation within 30 days after the mailing of the notice required by subsection (a) of Code Section 51-7-84 or prior to a ruling by the court relative to the civil proceeding, claim, defense, motion, appeal, civil process, or other position, whichever shall first occur; provided, however, that this defense shall not apply where the alleged act of abusive litigation involves the seizure or interference with the use of the injured person's property by process of attachment, execution, garnishment, writ of possession, lis pendens, injunction, restraining order, or similar process which results in special damage to the injured person.

(b) It shall be a complete defense to any claim for abusive litigation that the person against whom a claim of abusive litigation is asserted acted in good faith; provided, however, that good faith shall be an affirmative defense and the burden of proof shall be on the person asserting the actions were taken in good faith.

(c) It shall be a complete defense to any claim for abusive litigation that the person against whom a claim of abusive litigation is asserted was substantially successful on the issue forming the basis for the claim of abusive litigation in the underlying civil proceeding.
