O.C.G.A. § 23-3-110: Bill of peace; when entertained; ancillary injunction.

(a) It being the interest of this state that there shall be an end of litigation, equity will entertain a bill of peace:

(1) To confirm some right which has been previously satisfactorily established by more than one legal trial and is likely to be litigated again;

(2) To avoid a multiplicity of actions by establishing a right, in favor of or against several persons, which is likely to be the subject of legal controversy; or

(3) In other similar cases.

(b) As ancillary to this jurisdiction, equity will grant perpetual injunctions.
