This constitutional responsibility is an important one, the exercise of which we do not undertake lightly, as it results in a binding and conclusive determination of the jurisdiction of the Court of Appeals. See, e.g., Paul Robinson, Inc. v. Haege, 218 Ga. App. 578, 579 ( 462 S.E.2d 396) (1995); Rewis v. Browning, 153 Ga. App. 352 (1) ( 265 S.E.2d 316) (1980); Hinton v. Ga. Power Co., 126 Ga. App. 416 (1) ( 190 S.E.2d 811) (1972); Woods v. State, 117 Ga. App. 546 ( 160 S.E.2d 922) (1968); Trainer v. City of Covington, 111 Ga. App. 425-426 ( 142 S.E.2d 75) (1965). Included among those cases over which the constitution grants this court general appellate jurisdiction are "[a]ll equity cases."
However, when the Barons filed their counterclaim for recovery of the expenses which were the basis of State Farm's petition, they effectively turned the controversy from one in which State Farm was seeking declaratory relief into one in which they were seeking affirmative relief. The entire controversy over coverage under the policy became, at that point, a suit by the Barons for affirmative relief from State Farm and, in our opinion, rendered moot any question of whether State Farm was or was not entitled to declaratory relief. Cf. Trainer v. City of Covington, 111 Ga. App. 425 ( 142 S.E.2d 75) (1965). If there were any doubts before the Barons filed their counterclaim that all rights had accrued in the controversy, those doubts were removed when their counterclaim was filed.
This court does not have power to render advisory opinions. Trainer v. City of Covington, 111 Ga. App. 425 ( 142 S.E.2d 75). 5. All other enumerations are either rendered moot or have no merit.
It follows that Richardson was not entitled to declaratory relief, which in this context would be nothing more than " an advisory opinion from the trial court as to which party would succeed on the merits of any claim" pertaining to the completed multi-party transaction. Skelton, 235 Ga.App. at 509, 510 S.E.2d 76. See Baker, 271 Ga. at 214-215(1), 518 S.E.2d 879; Trainer v. City of Covington, 111 Ga.App. 425, 426, 142 S.E.2d 75 (1965). 2.
