Georgia Code Title 9. Civil Practice § 9-9-35

(a) If an arbitrator becomes de jure or de facto unable to perform his or her functions or for other reasons fails to act without undue delay, the arbitrator's mandate terminates if he or she withdraws from office or if the parties agree on the termination. Otherwise, if a controversy remains concerning any of these grounds, any party may request that the court specified in Code Section 9-9-27 decide on the termination of the mandate, which decision shall not be subject to appeal.

(b) If, under this Code section or subsection (b) of Code Section 9-9-34, an arbitrator withdraws from office or a party agrees to the termination of the mandate of an arbitrator, this shall not imply acceptance of the validity of any ground referred to in this Code section or subsection (b) of Code Section 9-9-33.
