Ellington, Justice.We granted George Bellamy’s pro se application for discretionary appeal to address whether the Superior Court of Muscogee County erred in entering an order denying the filing of Bellamy’s petition for mandamus. For the reasons set forth below, we reverse.

George Bellamy was convicted of malice murder in 1998 in Muscogee County. See Bellamy v. State , 272 Ga. 157, 527 S.E.2d 867 (2000). The indictment named him as "George Bellamy aka Michael Johnson aka Lamar Ellison." In 2014, Bellamy filed pro se a "Motion for Leave to Correct Indictment Misnomer," asserting that his legal name is actually Michael Johnson and that Bellamy is an alias. The motion was denied by Judge William C. Rumer in 2014, and this Court dismissed his untimely direct appeal from that order on February 2, 2015.

On July 3, 2017, with the assistance of counsel, Bellamy filed a substantially similar second motion entitled "Motion to Correct Clerical Error." On April 16, 2018, after two requests for a ruling had gone unanswered, Bellamy, pro se, filed a "Petition for Writ of Mandamus," seeking to have Judge Rumer "consider and issue a ruling on the pending motion to correct the clerical error." On June 7, 2018, another judge of the Superior Court of Muscogee County issued a form order denying the filing of Bellamy’s "Civil Complaint" against Judge Rumer pursuant to OCGA § 9-15-2 (d), pertaining to the judicial review of pro se filings. The superior court found that Bellamy’s pleading showed on its face such a complete absence of any "justifiable [sic] issues of law or fact that it cannot be reasonably believed that this Court could grant" the requested relief.

Upon granting Bellamy’s application for a discretionary appeal, this Court directed the parties to consider whether the superior court erred in denying the filing of the mandamus petition. Based on exhibits attached to its briefs, the State contends that Judge Rumer denied Bellamy’s pending motion to correct the alleged misnomer on September 25, 2018; therefore, the State argues, the issue raised in this appeal is moot. However, that order is not included in the official appellate record and the exhibits attached to the State’s brief are not part of the official record on appeal. Consequently, there is no evidence before this Court supporting the State’s contention that the appeal is moot. See Arnold v. State , 286 Ga. 418, 420 (2), 687 S.E.2d 836 (2010) (An exhibit attached to a brief which is not a part of the appellate record "does not constitute evidence that can be considered by this Court on appeal." (citation omitted)). Based on our review of the record, we must conclude that the superior court’s order denying the filing of Bellamy’s mandamus petition pursuant to OCGA § 9-15-2 (d) was error. A justiciable issue is patent from the face of Bellamy’s mandamus petition, that is, whether Judge Rumer failed to comply with his duty to timely rule on Bellamy’s pending motion. The record shows that, when Bellamy filed the mandamus petition, he had been waiting for a ruling on his motion for nine months, which is considerably outside the maximum period during which a judge is required to decide a pending motion. See OCGA § 15-6-21. For these reasons, the order denying the filing of Bellamy’s mandamus petition must be reversed.

Judgment reversed.
