Georgia Code Title 9. Civil Practice § 9-6-27

(a) Upon the presentation of an application for mandamus, if the mandamus nisi is granted the judge shall cause the same to be returned for trial not less than ten nor more than 30 days from such date. The defendant shall be served at least five days before the time fixed for the hearing.

(b) If no issue of fact is raised by the application and answer, the case shall be heard and determined by the court without the intervention of a jury.

(c) If an issue of fact is involved, it may be heard by the judge upon the consent of all parties. Otherwise, the case shall be set for trial upon the first day of the next term of the superior court as other jury cases are tried. However, if the court has a scheduled session for jury trials which will occur before the next term, the case shall stand for trial at the present term.
